Bruxism – Teeth Grinding

Bruxism is the act of clenching or grinding your teeth. The problem occurs mostly at night, when most people are unaware that they have the habit. An estimated 8% of adults are teeth grinders, and 1/3 of parents report that their children have the habit.

What are the causes?

Exactly why bruxism occurs is not clear. But there are circumstances that make people more susceptible to it.

  • Anxiety and stress – People with nervous tension, anger, pain, or frustration can put forceful tension on their teeth. It is estimated that 70% of bruxism is related to anxiety and stress.
  • Sleep disorders – Snoring, obstructive sleep apnea, sleep talking, or aggression while asleep increase the likelihood that a person also grinds his or her teeth while asleep.
  • Lifestyle – Bruxism is much more common in people who use psychoactive substances (antidepressants, anti-anxiety medication, sleep aids, tobacco, caffeine, and alcohol).

What are the symptoms of teeth grinding?

  • Gum recession, abnormal wearing of the teeth, tooth pain
  • Neck pain, jaw pain, earaches, headaches
  • Jaw clicking or popping
  • Sensitivity in the teeth

Why seek treatment?

If teeth grinding is left untreated, the results can be damaging to your oral health and overall health. In addition to toothaches, headaches, and facial pain, your sleep can be affected. If the problem progresses, it can lead to tempormandibular joint (TMJ) disorder. Teeth can wear and break and require restoration.

Bruxism treatment

An occlusal split, or mouthguard, can be custom fit by your dentist for maximum effectiveness. The mouthguard moves your lower jaw forward to limit teeth grinding. It also relaxes the jaw, which in turn relieves jaw pain and soreness.

If it is suspected that teeth grinding is related to sleep apnea, a sleep study may be recommended. A sleep apnea machine (CPAP) or an oral appliance can be used to alleviate sleep apnea.

Behavioral approaches, including relaxation techniques, medication, or reducing stress factors in life may be recommended.
