Bruxism is not an uncommon problem, faced by as many as 20% of the population. Commonly known as tooth grinding or clenching, it is usually a nighttime activity and is classified as a sleep disorder and a habitual behaviour.
“I Don’t Have Bruxism!” … Are You Sure?
Unless someone observes you grinding your teeth in your sleep, you may not even be aware that you are engaging in this behavior. Here are some signs that may serve as clues of bruxism:
- chewed tissue on inside of cheek
- cracks in teeth, tooth wear, failed fillings and damaged dental work
- earaches, itchy ears, ringing in the ear
- flattened and worn-down teeth
- jaw joint or muscle tenderness or sorenes
- headaches—especially in the morning
- loose teeth
- tooth sensitivity—especially to temperature changes
- dizziness
- sore neck or shoulders
Consequences of Tooth Grinding and Clenching
In addition to the symptoms described above, bruxism is one of the leading causes of tooth loss and gum recession. Teeth and gums can only withstand so much excessive stress and force. Eventually, they become severely compromised by the ongoing stress and pressure created by the constant clenching and grinding. Severe cases of bruxism can cause or worsen Tempomandibular Joint (TMJ) disorder and even change the appearance of one’s face.
Nightguards
Dental nightguards or splints are often successful in preventing the ongoing abrasion of tooth surfaces. The most effective of these appliances are custom-made from molds taken of the patients upper and lower teeth. These mouthguards are typically worn on a long-term basis throughout every night.
Anterior Deprogrammer
For many people, a specific type of nightguard is believed to be more effective in eliminating bruxism than a standard nightguard or splint. This type of appliance does not permit the back teeth to come into contact and grind against each other.
Other Tips to Help Stop Grinding
- avoid foods and beverages containing caffeine
- avoid alcohol, which seems to intensify grinding
- avoid chewing gum or chewing on pens, pencils or other non-edible items; fingernail chewing can also lead to bruxism
- during the day, try not to clench by putting the tip of your tongue in between your front teeth
- try to remain relaxed and reduce stress as much as possible
- relax your jaw muscles before bed with a warm heating pad or washcloth if they are stiff or painful
Above all else, discuss this problem with both your dentist and your physician. Sometimes bruxism may be a result of problems with the respiratory, digestive or nervous system. Your dentist can assist you with treatment and give you options to repair any possible damage to teeth and gums.
