Good day, someone's children were grinding their teeth at night like in a dream? We have this noise every night, we went to a neurologist, dentist, pediatrician. I gave everyone in the family antiparasitic treatment. Nothing helped. The only thing that gave a temporary effect was treatment from the neurologist. Has anyone encountered bruxism around 2-3 years old? And how was it treated by which specialist?
