Why Does a Baby Grind Their Teeth?

Teeth grinding in infants may be caused by temporomandibular joint dysfunction, parasitic infections, chewing muscle coordination issues, or tooth replacement. Here are some possible reasons:

1. Temporomandibular Joint Dysfunction

If a baby uses their chewing muscles excessively or chews with one side of their mouth for extended periods, it can lead to temporomandibular joint dysfunction, which can cause nighttime teeth grinding. Additionally, poor dental occlusion can also contribute to teeth grinding. In such cases, parents should take their child to a dentist for orthodontic correction and treatment.

2. Parasitic Infections

Some children may have parasitic infections that can cause nighttime teeth grinding. Parents can give their child anti-parasitic medication to resolve this issue.

3. Chewing Muscle Coordination Issues

If a child frequently sleeps with their head tilted to one side, it can lead to chewing muscle coordination issues. Long-term pressure on the chewing muscles can cause abnormal contractions, resulting in teeth grinding.

4. Tooth Replacement

During the tooth replacement period, children may experience itching in their gums, which can cause mild teeth grinding. Parents don't need to worry about this as it is a normal phenomenon. It is essential to encourage good oral hygiene practices in children during this time.
