can teeth whitening be repeated?

[Pete X]

Hi

I would like to have my teeth whitening again, although I had them whitened one year ago with britesmile at a clinic in london. The results were great at the time but my teeth look yellow now and the whitening has almost fully faded. I would like to know if teeth whitening can be repeated every year just to top up the whitening results?

Teeth whitening can be repeated as long as your teeth are healthy. Generally home whitening kits are used to top up power whitening when the teeth whitening results fade because power whitening carries higher risk of damage to tissues than home teeth whitening.
