Bruxism describes a range of related behaviours including teeth grinding, gnashing and clenching of the jaw. Its usually a subconscious behavior performed whilst asleep.
Bruxism can lead to permanent damage to the teeth as the enamel is worn away. However it can also lead to headaches and disorders of the TMJ (temperomandibular joint). Bruxism sufferers are three times more likely to suffer headaches as well as aching jaw and face muscles; earache; tightness/ stiffness of the shoulders; limitation of mouth opening; sleep disruption; excess tooth mobility; inflamed and receding gums. A stressful lifestyle is also a factor in bruxing.
The most effective way to reduce the tension from bruxing is to wear a night guard or occlusal splint. This is a device that is kept in the mouth overnight and acts as a spacer so you avoid tooth to tooth contact as well as deprogramming the muscles to reduce the tension.

Migraines can be debilitating especially if you suffer from ones that make you feel sick and you end up having to take a couple of days off work. Even regular headaches can make you lose focus and have a negative impact on your life.
Did you know that headaches and migraines can be triggered by clenching of the jaw? The term is called bruxing with is a parfanctional habit. Contrary to common belief, functional habits such as chewing are not the main cause of the wearing of teeth. Parafunctional habits are the most destructive forces for a number of reasons. Whereas teeth rarely come into contact during normal chewing, grinding of teeth may occur 1–4 hours in a 24 hour period, most often during sleep. The amount of force placed on teeth during functional habits is 20–80 psi (0.14–0.55 MPa), but the pressure can range from 300 to 3000 psi (2.07 to 20.7 MPa) during parafunctional habits. Thats a minimum of 15 times more pressure!
The direction of forces during functional habits are placed vertically along the long axis of teeth, which is the least harmful because of the anatomical structure of the attachemnt of teeth to the bone. On the other hand, parafunctional habits direct their forces horizontally and that is when un due stress can occur on the TMJ (temporomandibular joint).
People who suffer from headaches, neck, shoulder and backache often have parafunctional habits. This kind of habit can damage your teeth, jaw joint and affect your chewing muscles. The treatment to reduce the force from bruxing is straight forward: an occlusal splint or nightguard can reduce the tension by 75%. Just ask your dentist about it and imagine less migraines and headaches in the future!

Bruxism (teeth grinding) is the involuntary clenching or grinding of the teeth. This subconscious behaviour most often occurs when you are asleep. Bruxism can create huge forces and can cause broken teeth, loose fillings and loss of tooth surface enamel. Bruxing can also cause sensitivity to hot and cold drinks and food, headaches, trigger migraines and other facial pain. The leading cause of tooth grinding is stress. These times of stress can be episodic but can lead to habitual clenching or grinding.
The best non invasive method for reducing bruxing is a deprogramming splint. These are sometimes called night guards, bite guards, occlusal splints and many other names. It is an appliance which is generally worn at night. It acts as a spacer between the teeth and can reduce the bruxing habit by 70%. This reduction in biting force can relieve triggering factors for migraines, headaches and prevent damage to the teeth.

Teeth grinding is much more common than people think. A client came to Time Dental suffering from sensitve teeth. It happened every time he had something cold to drink and sometimes when he brushed his teeth. He had been tolerating this for a very long time and thought it was normal.
On assessing his mouth, teeth and gums, he had alot of wear on his back teeth. Vertical enamel fracture lines were also visible on the majority of his front teeth. But he also had multiple large holes/cavities at the gum line of many of his back teeth. He reported suffering from regular headaches and again thought that this was just something people regularly suffered from.
What he was not aware of was that he was clenching and grinding his teeth at night and in the daytime. If you are someone who grinds your teeth or even clench your teeth together you are putting 10 times more pressure on your teeth than normal. This huge amount of stress causes the thinnest part of enamel on your teeth which is by the gum line to start shattering. The end result is a hole by the gum line of the tooth called an Abfraction cavity. If left as a cavity the tooth is exposed as it has lost its enamel layer and is now susceptible to cold temperature changes and tooth decay.
To help stop the cavity from progressing, white fillings or composite fillings are a great way to seal the hole and protect the tooth around the gum line. The next step is to deal with the tooth grinding. The best way that consistently delivers results is to provide a night guard or splint that helps reduce the stress and tension on the teeth. This will also reduce the occurance of headaches.
