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.

My entire family gives Dr. Schmidt 5 stars! He is skilled, experienced, trustworthy, and you can tell he enjoys his job. My two children love to go to the dentist, and I think that speaks volumes. He makes you feel comfortable and at ease, even during unpleasant procedures. I trust Dr. Schmidt completely and know that he would never recommend unnecessary dental work. Oh, and by the way you cannot feel a thing when he gives you a shot.
The office staff is fun and super helpful as well. If you are looking for a dentist you will not regret coming to Dr. Schmidt!

THE place to go if you're scared of dentists. Dr. Schmidt is funny and relaxes you immediately. He makes a real effort so you don't feel pain. I hadn't gone in years and was hyperventilating before I went. Dr Schmidt's whole team was great. Told them I was nervous and they were great. Now, I'm never afraid to go. I trust him to the point that I eventually got braces (his recommended orthodontist was fabulous too) and today I've got a great smile.
He has several chairs. They can take X-rays right in the chair, and you can see them yourself on a big screen.
The office is a bit hidden in the interior corner of the shopping center, so you won't notice it from the parking lot.
My embarrassing moment... Going to the fish and chip place a few spots away to buy British candy afterward. I don't eat it right away!

Dr. Schmidt is the best dentist around. I have experienced a few different approaches and Dr. Schmidt's is the most comforting and knowledgeable. You never leave feeling negative or like you got raked over the coals. I was referred to Dr. Schmidt years ago by a close family friend and have not turned back. My family sees him and I have referred everyone I know to him. Over the years his staff has changed a lot but everyone I have come across is great. Highly recommended!

Jonathan G.
