When it comes to teeth whitening, dentists say custom-fit bleaching trays for at-home whitening are the most effective option. Three-quarters of the dentists in this survey said it works great.
Dentists feel that in-office gel bleaching and laser teeth whitening work okay, but they are not impressed with store-bought teeth whiteners.
“The at-home custom-fit tray whitening method works best," said one dentist. "Over the course of several days, the patient can control the degree of tooth whitening to her own preferences — something that cannot be said for the other methods. And once the custom trays are made, the patient can easily and efficiently perform the later 'touch-ups' that inevitably will be needed with the passage of time."
"Who trusts a pimply faced kid at the mall to whiten their teeth?" asked a California dentist.
"Any monkey can whiten teeth," said a Florida dentist. "The art is whitening to the fullest extent possible, which varies from person to person; and then to do it predictably without creating sensitivity. Sensitivity can be a real show stopper."
