What is Bruxism?
Bruxism is when you clench (tightly hold your top and bottom teeth together) or grind (slide your teeth back and forth over each other) your teeth. People can clench and grind without being aware of it. It can happen during both the day and night, although sleep-related bruxism is often a bigger problem because it is harder to control.
If you often wake up with jaw pain, earaches, or headaches, you may have a common condition called “bruxism.”
Possible Complications with Bruxism
If not corrected, bruxism can lead to many complications listed below:
- Increased dental or TMD problems
- Fractured teeth
- Tooth Loss
- Receding gums
Causes of TMJ & Migraine Headache
There is some disagreement about the cause of bruxism. Daily stress may be the trigger in many people. Some people probably clench their teeth and never feel symptoms. Factors that influence whether or not bruxism causes pain and other problems will vary from person to person. They may include:
- How much stress you are under
- How long and tightly you clench and grind
- Whether your teeth are misaligned or a new filling or crown is ‘high’
- Your posture
- Your ability to relax
- Your diet
- Your sleeping habits
- Tinnitus (ringing, hissing, buzzing in ears)
Clenching the teeth puts pressure on the muscles, tissues, and other structures around your jaw. Dr. Walk has seen patients with broken veneers, fractured teeth, and damaged porcelain crowns, all caused by clenching and grinding. These symptoms can cause temporomandibular joint problems (TMJ).
Other Symptoms of bruxism include the following:
- Anxiety, stress, and tension
- Enlarged facial muscles (masseters and temporalis especially)
- Earache (due in part because the structures of the temporomandibular joint are very close to the ear canal, and because you can feel pain in a different location than its source; this is called referred pain)
- Eating disorders
- Muscle tenderness, especially in the morning
- Hot, cold, or sweet sensitivity in the teeth
- Insomnia and sleep interruption episodes
- Sore or painful jaw
- Tinnitus (ringing, hissing, buzzing in ears)
How is TMJ diagnosed?
An exam can rule out other disorders that may cause similar jaw pain or ear pain, including:
- Dental disorders
- Ear disorders, such as ear infections
- Problems with the temporomandibular joint (TMJ)
Dr. Walk will, in many cases send patient home with an overnight EMG testing device to ascertain bruxism, grinding and clenching. The test results usually reveal mild, medium or severe bruxism. Treatment will vary accordingly.
The goals of treatment are to reduce pain, prevent permanent damage to the teeth, and reduce clenching as much as possible.
The following self-care steps may help relieve pain:
- Avoid eating hard foods like nuts, candies, and steak.
- Avoid chewing gum.
- Drink plenty of water every day.
- Get plenty of sleep.
- Massage the muscles of the neck, shoulders, and face. Look for small, painful nodules called trigger points that can cause pain throughout the head and face
- Relax your face and jaw muscles throughout the day. The goal is to make facial relaxation a habit.
- Try to reduce your daily stress and learn relaxation techniques.
Botox and TMJ Treatment
Dr. Walk usually takes a frontline approach for muscle relaxation utilizing Botox. This is very helpful and usually reverses symptoms in as little as one week. Neuromuscular toxins (Botox) in combination with mouth guards do wonders for these issues.
How Do Mouth Guards Help With TMD?
Night guards are an easy way to prevent the wear and damage that teeth-grinding causes over time. Custom-made by our office from soft material to fit your teeth, a night guard is inserted over your top or bottom arch and prevents contact with the opposing teeth.
Splints for TMJ Treatment
To prevent damage to the teeth, mouth guards or splints are often used to treat teeth grinding, clenching, and TMJ disorders. A splint may help protect the teeth from the pressure of clenching.
Some people find that the symptoms go away as long as they use the splint, but pain returns when they stop. The splint may also not work as well over time.
Types of Splints
There are many types of splints. Some fit over the top teeth, some on the bottom. They may be designed to keep your jaw in a more relaxed position or provide some other function. If one type doesn’t work, another may.
A splint called the NTI-tss fits over just the front teeth. The idea is to keep all of your back teeth (molars) completely separated, under the theory that most clenching is done on these back teeth. With the NTI, the only contact is between the splint and a bottom front tooth.
When to Contact a Medical Professional
See a dentist immediately if you are having trouble eating or opening your mouth. Keep in mind that a wide variety of possible conditions, from arthritis to whiplash injuries, can cause TMJ symptoms. Therefore, see your dentist for a full evaluation if self-care measures do not help within several weeks.
