Bruxism (Teeth Grinding) - What you need to know

in

Article By Dr. Rouel Vergara, D.M.D., Gen.Dent.Cert.

Bruxism, commonly known as teeth grinding, is a condition considered as movement disorder of the jaw.

Grinding or clenching of teeth usually characterises this condition.

Even though the cause of bruxism is unknown, experts suggest that psychological stress plays a major role. 

According to  recent studies available, women are more affected than men.

It is estimated that between 20%-30% of  the adult population are affected and approximately 15% of kids have a similar condition.

Depending on the severity of teeth grinding, sometimes it may not require treatment. However, bruxism can lead to many issues in oral health. 

This includes tooth damage, breakage of dental fillings, toothache, headache and temporomandibular joint (TMJ) disorder. 

Most patients suffering from bruxism are unaware that they have one until complications develop.

So it is important to know the signs and symptoms of bruxism.

Here are the things you need to know to determine if you suffer from this condition:

 

  1. Grinding of teeth at night that may be loud enough, making it noticeable by your partner

  2. Teeth becoming worn down leading to exposed deeper layer of teeth

  3. Increased sensitivity of teeth

  4. Toothache

  5. Tired and tight jaw muscles even after you’ve slept

  6. Headache

  7. Facial pain

  8. Earache

  9. Indentations on tongue

 

As mentioned earlier, treatment of bruxism depends on the severity of the condition.

Solutions may vary from case to case.  Occlusal Splint (night guard) is the most common solution dentists can provide.

This dental device is worn at nighttime to protect teeth while sleeping.

There are also various jaw exercise and therapy options that can be implemented.

Here are my other helpful tips to minimise teeth grinding:

 

  1. Relax. Reduce stress in your life or work.

  2. Avoid alcohol. It increases teeth grinding after consumption

  3. Reduce caffeine intake.

  4. Do not chew on objects such as pens or pencils
