How old does one have to be in order to have whitening performed on them?
Most dentists will not perform an In-Office whitening session on the teeth of someone younger than fourteen years of age. In fact, many prefer to wait until they are closer to sixteen. If some compromise needs to be reached, the dentist may choose to fabricate custom whitening trays and give out a very low concentration gel, or recommend over-the-counter whitening strips or products that are milder and less effective.
