Why my child chew his teeths when he is in sleep again and again?

Allergies?: Bruxism in children has been linked to allergies. Other causes are possible. Make an appointment with your dentist, pedodontist or pediatric ENT for an evaluation.

Normal & can be tx.: Most children clench and/or grind their teeth at night. This is very common. Depending on the age of the child, a appliance can be made to protect their teeth at night. So don't worry but do address the problem with your dentist before too much damage is done.

Possibilities: Three main reasons for nighttime pediatric teeth grinding are 1)digestive problems, especially sensitivity to dairy-so no dairy before bed;use of probiotics and flax seed or cod liver oil(1tsp per day helps 2) airway issues-clenching the jaws together opens the pharyngeal airway-check for enlarged adenoids/tonsils or 3)a crossbite between the upper and lower teeth-upper jaw may need expansion.

Many causes: It is a common condition that actually have multiple possible causes. Research literature has suggested that childhood teeth grinding usually stops naturally once they get more and more permanent teeth. Because the teeth are changing and the face is growing, night guard that locks the teeth in place is not recommended. Bad as they sound, the damage to teeth is usually minimal.
