Is airflow technique safe for cleaning kids stained teeth?my daughter has 2 years and a half.the stains on teeth are caused by bacteria(dr. confirmed)

It is perfectly safe: air flow polishing technique is far superior to traditional cleaning methods.

Pedodontist: Your child should have been under the care of a Dentist, preferably a Pediatric Dental Specialist (Pedodontist) since her 1st birthday. Discolored areas must be evaluated, may be infected teeth (cavities). If stained, not decayed, Airflow may be acceptable.
