Bruxism in children
Bruxism (grinding of teeth) in 11 months old is not very common but it can happen at any age.
Depending upon the duration, the teeth can wear away somewhat. There is nothing that you can do for an 11 month old. However, I have personally never seen enough severe damage to primary (baby) teeth that would become problematic. Often, it's temporary. Don't worry.See a pedodontist for child's 1st visit.
