I got Zoom whitening in June, but now my teeth are not as white as they were at first. My dentist gave me the impression that my teeth would stay white. I am concerned that I paid for treatment that is not going to last. Is this normal? And if so, how often will I need to repeat the treatment? Thank you. Jade

Jade –

When you receive in-office Zoom Whitening, your teeth will be ultra-bright–much brighter than in the following days. In a week or so, after your teeth rehydrate, the color might be a few shades darker than when you first received the treatment, but that’s normal. In-office Zoom treatment jumpstarts the process. But you may need to follow up with another in-office whitening session or take-home whitening.

Your dentist probably gave you a take-home whitening kit to use after in-office treatment. When you use the kit as directed by your dentist, your teeth will continue to whiten. But do not use the take-home kit more than directed by your dentist. It is possible to over-bleach your teeth. When that happens, teeth can get brittle and turn dark.

If you follow your dentist’s instructions for at-home treatment but want your teeth even whiter, speak with our dentist about it. They will explain how to safely whiten your teeth without causing a lot of sensitivity or damaging your tooth structure.
