Teeth Grinding


Bruxism is a condition of unconscious teeth clenching and grinding, either while awake or asleep. Mild bruxism may not require treatment. However, in some individuals, bruxism can be frequent and severe enough to lead to headaches, earaches, facial pain, jaw disorders, loss of teeth enamel, increased tooth sensitivity and flattening and or chipping of teeth.  

Bruxism sufferers who grind and clench their teeth while sleeping often woke up with a sore jaw. The constant clenching and grinding causes the masseter muscles located alongside the jaw to enlarge, eventually giving a square-like appearance of the jawline.

Chances are you may have bruxism and may not be aware of it until compilations develop, therefore it is important to know the signs and symptoms of bruxism and seek regular dental care.


Symptoms of bruxism may include:

  • Teeth grinding or clenching
  • Teeth that are flattened, fractured, chipped or loose
  • Worn tooth enamel, exposing deeper layers of your tooth
  • Increased tooth pain or sensitivity
  • Tired or tight jaw muscles, or a locked jaw that won’t open or close completely
  • Jaw, neck or face pain or soreness
  • Pain that feels like an earache
  • Dull headache starting in the temples
  • Damage from chewing on the inside of your cheeks
  • Sleep disruption

Your dentist may check for the following to evaluate the extent of bruxism:

  • Tenderness in your jaw muscles
  • Dental abnormalities such as broken or missing teeth
  • Other damages to your teeth, underlying bone and the inside of your cheeks with the help of X-rays.

Fortunately, treatments with BOTOX® (Botulinum Toxin Type A), can provide relief from jaw soreness and reduce the appearance of a square jaw.

How is the procedure done?

By injecting small doses of BOTOX® into the masseter muscles, it weakens the muscles to stop the involuntary grinding of the teeth and clenching of the jaw. This significantly relaxes the muscles, reduces the wear and tear on the teeth due to grinding and reduce the appearance of square jaw.

The dosage recommended for the treatment will vary depending on your individual situation and the severity of your bruxism.

Effectiveness of BOTOX® for Bruxism

Although BOTOX® injections are not a cure for bruxism, they can effectively control the uncomfortable symptoms of bruxism. The effects of BOTOX® typically lasts for four to six months and a repeat treatment is usually recommended within four to six months to maintain the desired result.

Consult our dentists if you have any of the symptoms listed above or any other concerns about your teeth or jaw.
