What is the reason why babies clench their teeth when sleeping?

Gnashing of teeth is what we usually call bruxism. The medical explanation for bruxism is the sound made by the upper and lower teeth biting together during sleep. Babies often grind their teeth when they sleep, and many parents will ask a question: What is the reason why babies grind their teeth when they sleep? Or why do babies grind their teeth when they sleep, but adults don’t?
