We know this will be very important to many.
Teeth Problems That Can Be Caused By A Bad Bite
Crooked, crowded and overlapping teeth can cause a wide range of problems, including:
- Tooth decay and gum disease – teeth that are not in proper alignment are hard to clean, particularly if they overlap. A build-up of plaque can cause tooth decay and gum disease.
- Wear and tear – the teeth of the upper and lower jaw are meant to come together in a specific way, with the upper teeth slightly protruding over the lower teeth. If they are misaligned, the action of chewing may grind the teeth unevenly.
- Jaw injury – the jaw joint is called the temporo-mandibular joint, which is also known as the TMJ. A bad bite may place stress and strain on this joint; this can cause localized problems such as pain, headaches as well as clicking or grinding noises when the jaw opens and closes.
- Speech impediments – many sounds are made with the tongue against or near the teeth. Misaligned teeth or jaws can interfere with speech.
- Self-confidence – a person may be reluctant to smile due to misaligned teeth.
How We Diagnose Orthodontic Problems
Problems with teeth and jaw alignment are identified using a number of tests, including:
- Dental X-rays both inside and outside the mouth
- Photographs both inside and outside the mouth
- Duplicate your bite in stone casts using impression materials
Once the problems are diagnosed, we create a step-by-step corrective plan. Any existing dental findings will likely need to be addressed before orthodontic treatment can begin. For instance, any decay must be treated and a dental cleaning must be performed. Also, teeth that are causing crowding may need to be removed before orthodontic treatment can be started.
Types of Treatment Options
The range of corrective orthodontic devices includes:
- Braces – Braces are the most efficient and accurate way of moving teeth. Brackets are cemented to each tooth that needs to be moved with special dental glue and are typically made of a clear ceramic material or stainless steel. These brackets act like a handle on the tooth so that it can be moved into its correct position when force is applied to the brackets. Visits to our office every few weeks are needed to adjust the forces on the teeth as the teeth are slowly moved into a desired position.
- Elastics or rubber bands are sometimes used in orthodontic treatment. Elastics are helpful in aligning the upper and lower jaws. When help is needed to move teeth, elastics may be stretched from these teeth and attached to a bracket on either the upper or lower teeth. It’s important to wear the elastics as instructed or orthodontic treatment will take longer.
- Headgear – if the teeth need extra pressure, headgear and bands may be worn. Basically, tensioned rubber bands are hooked to the braces and connected to a strap worn around the head, usually at night.
Risks of Orthodontic Treatment
Some of the risks of orthodontics include:
- Dental hygiene problems – braces and wires make cleaning the teeth more difficult. This can cause decay, discoloration and permanent marks.
- Mouthguards – It is strongly recommended that you obtain a special mouthguard if you play sports involving contact with another player.
- Relapse – teeth have fibers attached to the roots and those fibers have memory, which can caused properly aligned teeth to rotate out of alignment once the force on the teeth are removed. When wisdom teeth appear, also known as third molars, this can also caused properly aligned teeth to relapse. It is important that you wear your retainers for the prescribed time after fixed treatment has ended.
- Soft tissue injury – the braces may dig into the gums or cheeks.
Teeth cleaning is part of good oral hygiene and involves the removal of dental plaque from teeth with the intention of preventing cavities, gingivitis, and periodontal disease. Our experienced dental hygienists recommend a routine cleaning every six months.
We remove the plaque through a deep-cleaning method called scaling and root planing. Scaling means scraping off the tartar from above and below the gum line. Root planing gets rid of rough spots on the tooth root where the germs gather, and helps remove bacteria that contribute to the disease.
Medications may be used with treatment that includes scaling and root planing, but they cannot always take the place of surgery. Depending on the severity of gum disease, we may still suggest surgical treatment. Long-term studies will be needed to determine whether using medications reduces the need for surgery and whether they are effective over a long period of time. Here are some medications that are currently used:
What is it?
Why is it used?
How is it used?
|Prescription antimicrobial mouthrinse||A prescription mouthrinse containing an antimicrobial called chlorhexidine||To control bacteria when
treating gingivitis and after gum surgery
|It’s used like a regular mouthwash|
|Antiseptic “chip”||A tiny piece of gelatin filled with the medicine chlorhexidine||To control bacteria and reduce the size of periodontal pockets||After root planing, it’s placed in the pockets where the medicine is slowly released over time.|
|Antibiotic gel||A gel that contains the antibiotic doxycycline||To control bacteria and reduce the size of periodontal pockets||We place it in the pockets after scaling and root planing. The antibiotic is released slowly over a period of about seven days.|
|Antibiotic micro-spheres||Tiny, round particles that contain the antibiotic minocycline||To control bacteria and reduce the size of periodontal pockets||We place it in the micro-spheres into the
pockets after scaling and root planing. The particles release minocycline slowly over time.
|Enzyme suppressant||A low dose of the medication doxycycline that keeps destructive enzymes in check||To hold back the body’s enzyme response
— If not controlled, certain enzymes can break down gum tissue
|This medication is in pill form. It is used in combination with scaling and root planing.|
Temporomandibular joint and muscle disorders, commonly called “TMJ,” are a group of conditions that cause pain and dysfunction in the jaw joint and the muscles that control jaw movement. We don’t know for certain how many people have TMJ disorders, but some estimates suggest that over 10 million North Americans are affected. The condition appears to be more common in women than men. TMJ is referred to by different names such as TMD, TMJ disorder, and TMJ dysfunction.
For most people, pain in the area of the jaw joint or muscles does not signal a serious problem. Generally, discomfort from these conditions is occasional and temporary, often occurring in cycles. The pain eventually goes away with little or no treatment. Some people, however, develop significant, long-term symptoms.
What is the temporomandibular joint?
The temporomandibular joint connects the lower jaw, called the mandible, to the bone at the side of the head, which is the temporal bone. If you place your fingers just in front of your ears and open your mouth, you can feel the joints. Because these joints are flexible, the jaw can move smoothly up and down and side to side, enabling us to talk, chew, and yawn. Muscles and ligaments attached to and surrounding the jaw joint control its position and movement.
When we open our mouths, the rounded ends of the lower jaw, called condyles, glide along the joint socket of the temporal bone. The condyles slide back to their original position when we close our mouths. To keep this motion smooth, a soft disc lies between the condyle and the temporal bone. This disc absorbs shocks to the jaw joint from chewing and other movements.
The temporomandibular joint is different from the body’s other joints since the joint actually dislocates after opening past a certain point. The combination of hinge and sliding motions makes this joint among the most complicated in the body. Also, the tissues that make up the temporomandibular joint differ from other load-bearing joints, like the knee or hip. Because of its complex movement and unique makeup, the jaw joint and its controlling muscles can pose a tremendous challenge to both patients and health care providers when problems arise.
What are TMJ disorders?
Disorders of the jaw joint and chewing muscles – and how people respond to them – vary widely. Researchers generally agree that the conditions fall into three main categories:
Myofascial pain, the most common temporomandibular disorder, involves discomfort or pain in the muscles that control jaw function.
Internal derangement of the joint involves a displaced disc, dislocated jaw, or injury to the condyle.
Arthritis refers to a group of degenerative/inflammatory joint disorders that can affect the temporomandibular joint.
A person may have one or more of these conditions at the same time. Some people have other health problems that co-exist with TMJ disorders, such as chronic fatigue syndrome, sleep disturbances or fibromyalgia, a painful condition that affects muscles and other soft tissues throughout the body. It is not known whether these disorders share a common cause.
People who have a rheumatic disease, such as rheumatoid arthritis, may develop TMJ disease as a secondary condition. Rheumatic diseases refer to a large group of disorders that cause pain, inflammation, and stiffness in the joints, muscles, and bone. Both rheumatoid arthritis and some TMJ disorders involve inflammation of the tissues that line the joints. The exact relationship between these conditions is not known.
How jaw joint and muscle disorders progress is not clear. Symptoms worsen and ease over time, but what causes these changes is not known. Most people have relatively mild forms of the disorder. Their symptoms improve significantly, or disappear spontaneously, within weeks or months. For others, the condition causes long-term, persistent and debilitating pain.
What causes TMJ disorders?
Trauma to the jaw or temporomandibular joint plays a role in some TMJ disorders. But for most jaw joint and muscle problems, scientists don’t know the causes. For many people, symptoms seem to start without obvious reason. Research disputes the popular belief that a bad bite or orthodontic braces can trigger TMJ disorders. Because the condition is more common in women than in men, scientists are exploring a possible link between female hormones and TMJ disorders.
There is no scientific proof that clicking sounds in the jaw joint lead to serious problems. In fact, jaw clicking is common in the general population. Jaw noises alone, without pain or limited jaw movement, do not indicate a TMJ disorder and do not warrant treatment.
The roles of stress and tooth grinding as major causes of TMJ disorders are also unclear. Many people with these disorders do not grind their teeth, and many long-time tooth grinders do not have painful joint symptoms. Scientists note that people with sore, tender chewing muscles are less likely than others to grind their teeth because it causes pain. Researchers also found that stress seen in many persons with jaw joint and muscle disorders is more likely the result of dealing with chronic jaw pain or dysfunction than the cause of the condition.
What are the signs and symptoms?
A variety of symptoms may be linked to TMJ disorders. Pain, particularly in the chewing muscles and/or jaw joint, is the most common symptom. Other likely symptoms include:
Radiating pain in the face, jaw, or neck.
Jaw muscle stiffness.
Limited movement or locking of the jaw.
Painful clicking, popping or grating in the jaw joint when opening or closing the mouth.
A change in the way the upper and lower teeth fit together.
How are TMJ disorders diagnosed?
There is no widely accepted, standard test now available to correctly diagnose TMJ disorders. Because the exact causes and symptoms are not clear, identifying these disorders can be difficult and confusing. Currently, we note the patient’s description of symptoms, take a detailed medical and dental history, and examine problem areas, including the head, neck, face, and jaw. Imaging studies may also be recommended.
You may want to consult us to rule out known causes of pain. Facial pain can be a symptom of many other conditions, such as sinus or ear infections, various types of headaches, and facial neuralgias (nerve-related facial pain). Ruling out these problems first helps in identifying TMJ disorders.
How are TMJ disorders treated?
Because more studies are needed on the safety and effectiveness of most treatments for jaw joint and muscle disorders, experts strongly recommend using the most conservative, reversible treatments possible. Conservative treatments do not invade the tissues of the face, jaw, or joint, or involve surgery. Reversible treatments do not cause permanent changes in the structure or position of the jaw or teeth. Even when TMJ disorders have become persistent, most patients still do not need aggressive types of treatment.
Because the most common jaw joint and muscle problems are temporary and do not get worse, simple treatment is all that is usually needed to relieve discomfort.
There are steps you can take that may be helpful in easing symptoms, such as:
Eating soft foods.
Applying ice packs.
Avoiding extreme jaw movements (such as wide yawning, loud singing, and gum chewing).
Learning techniques for relaxing and reducing stress.
Practicing gentle jaw stretching and relaxing exercises that may help increase jaw movement.
We can recommend exercises if appropriate for your particular condition.
For many people with TMJ disorders, short-term use of over-the-counter pain medicines or nonsteroidal anti-inflammatory drugs (NSAIDS), such as ibuprofen, may provide temporary relief from jaw discomfort. When necessary, we can prescribe stronger pain or anti-inflammatory medications, muscle relaxants, or anti-depressants to help ease symptoms.
We may recommend an oral appliance called a bruxism splint, stabilization splint, night guard, or bite guard, which is a plastic guard that fits over the upper or lower teeth. Stabilization splints are the most widely used treatments for TMJ disorders. Studies of their effectiveness in providing pain relief, however, have been inconclusive. If a stabilization splint is recommended, it should be used only for a short time and should not cause permanent changes in the bite. If a splint causes or increases pain, stop using it and let us know.
The conservative, reversible treatments described are useful for temporary relief of pain – they are not cures for TMJ disorders. If symptoms continue over time, come back often, or worsen, please let us know.
Other types of treatments, such as surgical procedures, invade the tissues. Surgical treatments are controversial, often irreversible, and should be approach with caution where possible. There have been no long-term clinical trials to study the safety and effectiveness of surgical treatments for TMJ disorders. Nor are there standards to identify people who would most likely benefit from surgery. Failure to respond to conservative treatments, for example, does not automatically mean that surgery is necessary.
Wisdom teeth get their name because they usually appear around age 18. They can erupt straight, crooked or not at all. Even if they come in straight, wisdom teeth might need to be extracted due to a lack of space and the ability to be cleaned and maintained. Please read and view the images below for the various types of erupting patterns and impactions.
The lower tooth, in the image to the left, is partially vertically impacted. This means that part of the tooth is above the bone and visible in the mouth, and part of it is submerged in the bone. This tooth could still erupt properly as the tooth next to it is not in its way.
The upper tooth is fully vertically impacted. This means that the entire tooth is submerged in the bone.
If no tooth movement is shown after a few years, then we know that the teeth are impacted and should be considered for removal. This tooth could still erupt properly as the tooth next to it is not in its way.
The lower tooth, in the image to the left, is partially mesially erupted. This means that part of the tooth is above the bone and visible in the mouth and part of it is submerged in the bone and that is it tilted mesially, which means it is tipped toward the front of the mouth. This tooth will not likely erupt properly as the tooth next to it is in its way. These teeth typically need to be extracted because the bacteria that get under the gum tissue are almost impossible to clean, which causes an infection. The tooth next to the wisdom tooth can also decay due to the wisdom tooth.
The upper tooth is fully mesially impacted. This means that the entire tooth is submerged in the bone and is tipped toward the front of the mouth. These teeth can be observed for a few years but it is best if they get removed especially if other teeth need to be removed.
The lower tooth, in the image to the left, is partially distally erupted. This means that part of the tooth is above the bone and visible in the mouth, and part of it is submerged in the bone and that is it tilted distally, which means it is tipped toward the back of the mouth. This tooth will not likely erupt properly due to a lack of space toward the back of the jaw. These teeth typically need to be removed because the bacteria that gets under the gum tissue is almost impossible to clean, which then causes an infection.
The upper tooth is fully distally impacted. This means that the entire tooth is submerged in bone and is tipped toward the back of the mouth. These teeth can be observed for a few years but it is best if they get removed especially if other teeth need to be removed.
Both of the teeth, in the image to the left, are horizontally impacted. This means that the tooth is perpendicular where they should be. This tooth will not erupt properly since there is no place for them to go and there is almost no chance that they will be guided into proper position in the mouth.
These teeth typically need to be extracted but they can be observed for a few years but it is best if they get removed especially if other teeth need to be removed.
This is the most common type of fracture and it has the best long term prognosis. In this type of fracture, a part of the tooth can completely break off and, occasionally, no pain is felt after the tooth fractures.
Treatment for this type of fracture is to place a crown on the tooth. If the fracture extends into the middle part of the tooth, root canal therapy would be required in addition to a crown.
Vertical Furcation Fracture
This tooth has a vertical crack that extends vertically into or toward the furcation. The furcation, which is where the arrow is pointing, is the place where the tooth splits into two or more separate roots. The nerve is almost always involved in a vertical furcation crack. The tooth rarely separates into two pieces because the tooth is held in position by the surrounding bone.
The prognosis for this type of crack is fair but it depends on how deep the crack extends into the internal aspect of the tooth. The options are to treat the tooth with a root canal followed by a build up, post and crown or to extract the tooth.
Split Root Fracture
A split root fracture, known as a subgingival oblique fracture can be restorable but it depends on where the fracture ends. Subgingival means below the gumline. If the fracture is not to far below the gumline, the tooth can be restored with a procedure called crown lengthening followed by a crown. The tooth might also require root canal treatment. If the fracture is too far below the gumline, it is unrestorable and requires extraction.
These types of fractures occur for various reasons such as biting down on very hard foods or foreign objects, the presence of a previous filling in the tooth, and a tooth that had root canal therapy that was not treated with a crown.
Vertical Root Fracture
Vertical root fractures are not a very common type of fracture and it usually occurs with teeth that have had root canal therapy. If the fracture is very short in length, the tooth can possibly be saved by performing an apicoectomy. This involves gaining access to the root tip within the bone and removing the part of the root that is fractured. The only other option is an extraction.
Oblique Root Fractures
Oblique Root Fractures are fractures that are limited to the roots of teeth and the crown portion is intact. The fractured root is generally entirely below the gumline and usually entirely in bone.
If the fracture is close to the crown as shown by number 1 the tooth is usually unrestorable. The tooth might be able to be treated with endodontic therapy and root amputation if the remaining roots are strong and healthy but the overall prognosis is poor.
If the fracture is close to the tip of the root as shown by number 2, the tooth can try to be restored with root canal therapy. The root canal cannot be performed on the fractured root tip and the body tends to resorb the untreated piece. The prognosis for this procedure is fair to good, and regular exams are recommended to check how the body responds to the treatment.

How Teeth Are Restored
After diagnosing the problem and devising a treatment plan, the next step to restore a tooth to health is to make you comfortable. We will give you a local anesthetic so that you do not feel any discomfort. After the decay is removed, the tooth is ready to receive either a direct restoration or an indirect restoration.
A direct restoration means that the tooth can likely be restored in one visit and that there is sufficient tooth structure for the filling to go inside of the tooth. Examples of direct restorations are amalgam, which is silver-colored; and composite, which is tooth-colored. There have been more amalgam fillings placed worldwide than any other kind of filling, but tooth-colored fillings are being placed more frequently in recent years because they match the remaining teeth and look like the natural tooth.
An indirect filling means that the restoration is made outside of your mouth, either by a lab or by a milling machine. An indirect filling also needs to be cemented into place. Examples of indirect restorations are crowns, inlays, and onlays. A crown covers the entire tooth, an inlay fits inside the tooth and can replace a wall of the tooth, and an onlay replaces at least one cusp of the tooth.
Most indirect restorations take two or more appointments to complete, with the exception of restorations that are milled by a machine in the office. Cast gold is the most durable indirect restoration material, but porcelain ceramics are gaining in popularity because of their superior esthetic qualities.
Composite fillings are also called plastic or tooth colored fillings. Getting this kind of filling depends on where the tooth is in your mouth. There is a lot of force applied to the back teeth when we bite, so size and location is important when deciding to use this type of restoration. To place this filling, we remove all decay and other filling material from your tooth. A bonding material is placed and then the composite resin is put into the prepared tooth in thin layers. Each layer gets hard with the help of a special light that we hold over the tooth to cure the material. When the last layer of the filling is hard, we shape the material so it looks and feels natural.
- Single visit
- Conservative tooth preparation
- Does not corrode
Porcelain is the most natural looking of the choices we have to restore teeth. It is used either by itself in veneers, inlays, onlays, and crowns, as well as combined with metal for crowns. Porcelain restorations require two visits or they can be milled in the office with a milling machine. After the porcelain is cemented to your tooth, it is very difficult to notice that the tooth had any treatment at all.
- Resistance to surface wear
- Long lasting
- Wears well as it holds up to chewing force
When the structure of an entire tooth is compromised, a crown, which covers all of the surfaces of the tooth, will need to be placed. A dental crown is a tooth-shaped “cap” that is placed over a tooth — to cover the tooth to restore its shape and size, strength, and improve its appearance. The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.
The example to the left illustrates a fractured front tooth.
The first step is to prepare the tooth for a crown, which requires reduction of the tooth so that the lab has enough room to produce a life-like crown. We then take an impression, select the proper color for the crown and make a temporary, at which time the first appointment is completed.
Your case is then sent to the lab to make the crown, which is then tried in and adjusted. Our job is to communicate what your wishes and desires are to the lab technicians so your new crown will be in harmony with the surrounding teeth.
Before your new crown is cemented, we check the fit, the contacts, the bite and the color to make sure it has the same characteristics of your natural teeth.
