Bruxism

Bruxism refers to an oral parafunctional activity that occurs in most humans at some point in their lives.   Grinding of the teeth and clenching of the jaw are the two main characteristics of this condition, which can occur during the day or at night.

Bruxism is one of the most common known sleep disorders and causes most of its damage during sleeping hours.  The clenching and grinding which accompanies bruxism is symptomatic of a malfunctioning chewing reflex, which is turned off in non-sufferers when sleeping.  For sufferers, deep sleep or even naps cause the reflex nerve control center in the brain to turn off and the reflex pathways to become active.

Typically, the incisors and canines (front 6 upper and lower teeth) of opposing arches grind against each other laterally.  This side to side action puts undue strain on the medial pterygoid muscles and the temporomandibular joints.  Earache, depression, headaches, eating disorders, and anxiety are among the most common symptoms of bruxism; these symptoms also accompany health issues such as chronic stress, Alzheimer’s disease, and alcohol abuse.

Bruxism is frequently misdiagnosed or not diagnosed at all, because it is only one of several potential causes of tooth wear.  Only a trained professional can tell the difference between bruxing wear and wear caused by overly aggressive brushing, acidic soft drinks, and abrasive foods.

A BiteStrip® is an economical device used to diagnose bruxism at home.  The device itself is a small electromyography which senses and monitors any activity in the jaw muscles during sleep.  The frequency and severity of the condition can then be assessed and the best treatment plan can be formulated.

Reasons for the treatment of bruxism

Here are some of the main reasons why bruxism should be promptly treated:

  • Gum recession and tooth loss – Bruxism is one of the leading causes of gum recession and tooth loss. It damages the soft tissue directly and leads to loose teeth and deep pockets, where bacteria can colonize and destroy the supporting bone. 
  • Occlusal trauma – The abnormal wear patterns on the occlusal (chewing) surfaces can lead to fractures in the teeth, which may require restorative treatment.
  • Arthritis – In severe and chronic cases, bruxing can eventually lead to painful arthritis in the temporomandibular (TMJ) joints (the joints that allow the jaw to open smoothly).
  • Myofascial pain – The grinding associated with bruxism can eventually shorten and blunt the teeth.  This can lead to debilitating headaches and muscle pain in the myofascial region.
Treatment options for bruxism

There is no single cure for bruxism, though a variety of helpful devices and tools are available.  Here are some common ways in which bruxism is treated:

  • Mouthguards – An acrylic mouthguard can be designed from tooth impressions to minimize the abrasive action of tooth surfaces during normal sleep.  Mouthguards should be worn on a long-term basis to help to stabilize the occlusion as well as prevent damage to teeth and to the temporomandibular joint.
  • NTI-tss device – This device is fitted by a health professional and only covers the front teeth.  The goal of the NTI-tss is to prevent the grinding of the rear molars by limiting the contraction of the temporalis muscle.
  • Botox® – Botox® can be injected into the muscles to relax and weaken them.  Botox® is an excellent treatment for bruxism because it weakens the muscles enough to prevent grinding but not enough to interfere with everyday functions like chewing and speaking.

Other methods of treatment include relaxation exercises, stress management education, and biofeedback mechanisms.  When the bruxing is under control, there are a variety of dental procedures such as crowns, gum grafts, and crown lengthening that can restore a pleasant aesthetic appearance to the smile.

Dr. Salaveria and his staff were friendly, knowledgeable, professional, and they listened to me. I recently moved here from out of state and it looks like I've found my new dentist!

NO Pain! I am a HUGE baby when it comes to dental work and I am SO impressed. They made me feel comfortable and I am amazed that after a root canal, I had NO PAIN! Highly recommend their services. Their staff was wonderful from Rose at the front office to Brittany who assisted the procedure. Absolutely recommend!!!

My last experience at the dentist was as an uninsured individual about 6-8 years ago and I went to Western Dental. After almost 2 hours in their chair for 2 fillings and they had only gotten one of them done, I walked out of the office and never looked back. A few years went by and all of a sudden one of my molars caved in and I knew I had to get it taken care of. I now have insurance through my work and found Dr. Salaveria through their list of network providers. I saw all the positive reviews here on Yelp (and no negative ones...) and thought it was too good to be true but figured I would give them a shot. Best decision I ever made!

This is by far the best dentist experience I could have dreamed of. I had about 6 fillings done in less time than it took the Western Dental folks to do one. Not to mention he is very gentle and uses different techniques to make me comfortable since I have severe issues with my TMJ. I can almost fall asleep in his chair. They referred me out for two root canals (which have to be done by a specialist, and who they referred me to was also equally amazing) at this point and I have had one crown put in by them and will be having another crown done shortly. I can honestly say that I look forward to getting the work done with them. ....well... as much as anyone can look forward to dental work that is.

Bottom line: The reviews speak for themselves! Don't doubt it!
