Q.
I’ve had a cracking sound in my jaw for the last month. What causes this and will it go away on it’s own?
A.
Temporomandibular joints (TMJ) are involved in many functions such as eating, talking and swallowing. Like any other joint in the body, one or both can be injured, sometimes just by biting awkwardly or by sleeping with an unnatural head position. Obvious trauma such as falls, auto accidents, etc., can also severly injure these joints. Arthritis, loss of bite, poor dentures and loss of teeth are still other factors to consider as possible causes of TMJ dysfunction. Non- trauma related, sudden onset TMJ pain, whether cracking upon opening/closing or not, usually resolves by itself if the joint is rested for a period of time (no bagels, etc.). If the pain, cracking sound continues, a dentist should be seen. Often a guard/splint will be made to help aid in the healing process. Sometimes, an oral surgeon will be consulted for futher evaluation should conservative measures fail.

Q.
I am 90 years old. I wonder if it is possible to have a molar taken out? I have been using Oragel for quite some time now to relieve the pain.
A.
A dental visit is in order. An x-ray and an oral examination will be done to determine the status of the molar in question. Once the problem is determined, various choices will be presented to you. An extraction is usually the last choice unless the tooth is grossly infected/loose, severely fractured or causing you intense discomfort. The treating dentist will make the appropriate diagnosis. Your age is really not a factor. If an extraction or root canal is necessary, there are many ways to mitigate any medications you may be taking or physical diseases you may have. Today’s dentistry is not limited by age and extractions are no longer the only options available for sore teeth.
