Some people with bruxism unconsciously clench their teeth together during the day, often when they feel anxious or tense. This is different from tooth grinding or clenching that occurs at night, which is called sleep bruxism. Most children who are bruxers do so at night, while adults are either daytime or nighttime bruxers. (Mayo Clinic)

However, luckily he has grown out of the grind teeth period and now, I don’t hear it happens anymore. Many doctors said these are due to stress but as a mom, it is so hard to accept that our kid is stressed out when we have done all we can to give them a happy world.

But with all the start of kindie, new environment, new babysitter and etc, kids do get stressed and grind teeth in their sleep.
