Healthy Mouth, Healthy Kids

Underbite plus teeth grinding



My son is 15 months. He currently has his two front bottom and top teeth. He has an underbite and grinds his teeth continually. It is as if the teeth are aligned in such a way that they grind when he closes his mouth or chews. Can anything be done to stop it? Should we see a dentist? Have you heard of this happening before?


It is very common for infants and young children to grind their teeth and it usually causes no long-term problems. It is a good idea to have your child examined now by a pediatric dentist who can assess his developing occlusion ("bite") and discuss future treatment concerns/options.
