Can Clenching Your Teeth Cause Cavities

clenching teeth causes cavitiesResearch has proven that tooth clenching and grinding at night is one of the leading causes of damage to teeth. The need for dental work such as fillings, crowns and root canals in many cases is caused by clenching or bruxism. During clenching episodes, cracks develop on the surface of teeth. Bacteria gets into the cracks and causes cavities and decay. Often the cracks get down to the nerve of the tooth and they need root canals or extractions and dental implants.

Teeth Clenching with Amalgam Fillings

In cases where there are silver fillings, teeth clenching causes mercury gas release from amalgam fillings. It may be best to remove amalgam fillings in a safe way to prevent mercury exposure for the dentist, staff and patient. We use the IAOMT safe protocol to remove amalgam fillings.

Gum Disease Caused by Teeth Clenching

Tooth clenching and grinding is also one of the leading causes of gum disease. The gums support the teeth and cover and protect the roots of the teeth. When clenching occurs, the fibers that attach the gums to the roots of the teeth are torn loose and the gums lower leaving the roots of teeth exposed to the mouth. Loss of gum tissue is termed gum recession. The pressure from clenching also causes inflammation between the jaw bone and periodontal ligament. Long term inflammation in gum tissues results in bone loss. Deterioration of the gums leads to root cavities, fillings by the gum line, food trapping in between teeth and ultimately tooth loss. Teeth lost from gum disease can be replaced with implants.

Clenching is Caused by Sleep Apnea and Bite Misalignments

The two leading causes of tooth clenching and bruxism are night time airway issues such as upper airway restriction syndrome/obstructive sleep apnea and bite misalignments. Past orthodontics can also play a role in bruxism. Especially in cases where so called extraction-retraction braces have been done. Tooth clenching seems to be related to cases where orthodontics was done for long periods of time and where treatment outcomes were not good. Especially in cases where braces and extractions and retraction were used. If you you clench your teeth, you should be evaluated. There is a strong link between sleep apnea TMJ and a tied tongue.

 

Expanders can Prevent Kids from Teeth Clenching

Most teeth clenching can be prevented by promoting optimal oral and facial development in kids at a young age. Expanders in kids will stimulate the mouth to grow larger so all the teeth fit and the bite is balanced. Too much focus is on straight teeth and braces and not enough emphasis on the bite, airway and tongue function. Common expanders for kids include the Schwarz Appliance and the ALF Appliance.

Lack of Education and Training about Teeth Clenching in Dentistry

Most dentists are not trained in diagnosing clenching problems from the standpoint of correcting it. A qualified TMJ expert will diagnose the problems and treat the condition so the teeth grinding habits cease and do not occur anymore. Novel treatments correct the underlying cause of the TMJ problem and do not involve wearing a night guard or other dental TMJ appliance forever. In short, a cure for TMD is possible in many cases and lifetime night guards and clenching should not be accepted.

Why teeth grinding or bruxism is damaging to teeth and TMJ?

Bruxism or teeth clenching is an alarming condition and needs to be managed as soon as diagnosed.

  • Unchecked grinding of teeth can cause wearing of tooth enamel of all teeth exposing sensitive dentin,

  • If no definitive management is performed, eventually teeth will be removed and dental implants will remain the only option for restoration of lost structure and function of your mouth..

Is it safe to place porcelain crowns over my work or damaged teeth during Bruxism?

Metal free and tooth colored cosmetic restorations are popular these days. Advanced dentistry provides pleasing, functional and long lasting porcelain crowns for boosting your smiles and confidence at work. However, these porcelain crowns have the side effect of wearing natural tooth enamel when teeth grinding occurs. Porcelain or ceramic crowns must be avoided if you are suffering from Bruxism or teeth clenching. Zirconia is a much better material choice.

Proper evaluation of oral health conditions involving your TMJ and tooth contacts during function and rest is essential before including these restorations in the treatment. Consult a specialist TMJ dentist in this regard. Furthermore, continuous contact and grinding can result in chipping off and breakage of ceramic crowns due to their brittleness.

Can TMJ disorder develop the habit of teeth grinding?

  • Treatment of the root cause i.e. stress, anxiety or mal-aligned teeth,
  • Custom made and fit night guard fitting your teeth must be worn during sleep hours,
  • Jaw exercises,
  • Avoid biting and chewing hard foods,
  • Relax your face muscles.
