9mnth old baby teeth cut through last montg his irritable again this month and has bronchitis could his top teeth be cutting through waking a lot nite?

Possibly: You don't indicate if anything else is going on. Is the baby normal during the day, feeding well, without fever, etc. Also do not indicate who made the diagnosis of bronchitis and whether the cause was determined. A 9 month old should be evaluated by a pediatrician. Good luck and hope he is better soon.

Baby teeth: There are 20 of them that need to erupt. your child will have teething symptoms with each one. Important that you NOW schedule your child for 1st dental visit, preferably with a Pediatric Dental Specialist, a Pedodontist, who is trained to evaluate dent-facial growth and development.
