What is Bruxism?

Bruxism is a medical condition where babies grind their teeth during the day or at night. It doesn’t only affect babies but can occur in children and adults too. If you’ve never been a teeth grinder before, you still can be one later in life.

During the first few months, the babies experience a fair amount of body changes. Teething is one notable change you can see. A little discomfort might occur while the baby is developing teeth. It often happens when the babies are sleeping or under stress.

Causes of teeth grinding.

Teeth grinding can happen for multiple factors. It takes time for all the teeth to develop. Ofcourse, all teeth don’t grow at once. As your baby eats, it gets unstable as babies don’t have enough teeth to support the food. Another cause is due to unaligned teeth. If your baby is under the teething process, they might subconsciously be grinding their teeth to comfort the pain and uneasiness. Most children stop scraping after losing their baby teeth.
