Why is the child always "grinding his teeth" recently?

Patient's question:

No

Doctor's answer:

It should be due to the teething period. My baby started teething at eight months, and now at nine months, this is happening too. Even when there's nothing to play with and when bored, it's the same. Last week, I posted a similar question here, and a friend reminded me to give my baby more opportunities to bite things. Since then, this kind of forceful has reduced a lot.
