Is it serious for her teeth? What can I do to help her stop grinding her teeth? The noise is unbearable.

If a child is grinding their teeth, it is not usually a cause for concern, especially at a young age. It is a common behavior in infants and often just a passing phase. However, if the habit persists as they grow older, it can potentially wear down their teeth. In some cases, a dental appliance may be required to address this issue. It is important to monitor the situation and consult with a dentist if necessary.
