A complete guide to the NightGuard

What’s a Dental Night Guard?

So, are you facing teeth grinding issue during the day or while in sleep? Even if you not, having information about the teeth grinding disorder is always helpful. The medical term for teeth grinding disorder is Bruxism.

In teeth grinding, you either clench, gnash or grind your teeth very often unconsciously. This happens, particularly at night. Why Bruxism is bad for oral health? Well, because our teeth just are not built to withstand this constant force and abrasion. Continuous and extensive grinding our teeth caused various oral health issue, sometimes serious jaw pain.

According to the American Dental Association, about 10 to 15 percent of adults are suffering from the Bruxism; I believe this number is under-reported because most of us really do not know about it even if we have this problem.

How can you identify whether you have Bruxism or Not?

Well, most of the time, Bruxism gets unnoticed as there are no separate or clear symptoms related to the teeth. Awake bruxism starts in the morning and lasts until you sleep, so you can notice the teeth grinding habit. However, your family member can only notice Sleep bruxism, when they see you are grinding your teeth. When you grind your teeth, sometimes it makes noise that can be noticed by your partner easily.

If you are grinding your teeth frequently, you may wake with a sore jaw, a dull headache or tooth pain. These symptoms are very common but not necessarily, it is visible in call cases.

However, you may be experiencing bruxism if you notice any of the following symptoms:

  • Teeth grinding sound at night
  • Tight and painful Jaw muscles
  • Long-lasting pain in the face, cheek
  • Swelling on the side of your lower jaw caused by clenching
  • Flattened, fractured, chipped or damaged teeth.
  • Increased tooth sensitivity, tooth pain and loosen teeth
  • A headache and earache without having a problem with your ear. Jaw muscles movement triggers other related muscles and thus the pain.
  • Sleep abnormality like snoring, sleep talking and other disorder link sleep apnea.
  • Disorders that occur in the temporomandibular joints (TMJs), located just in front of your ears, which may sound like clicking when you open and close your mouth
