Crown, fillings and whitening
Stained, worn teeth. A crown, several tooth-colored fillings and whitening were done together.

Professional teeth whitening here comes two ways: in the dental chair, or with a kit you use at home. Which suits you depends on how fast you want it, how sensitive your teeth are, and what is already in your mouth.

Fillings and crowns do not whiten
Whitening works on natural enamel, so tell us about existing dental work first.
Whitening works best on stain that has built up on natural teeth.

A crown, a veneer or a filling keeps the shade it was made in, and teeth that are gray or purple may not respond to whitening.
Both lighten the shade of your natural teeth. They differ in how quickly, how much, and what you put up with on the way.

Whichever product is used, a whitening visit is three moves.
Whitening gel is made for enamel, not for gum tissue. The gums and lips are covered before any gel goes on.
The gel sits on the teeth for a set time, which depends on the product. Sensitive teeth are the reason to say so before it starts.
The gel can go on more than once in a visit. Afterwards the shade is checked against where you started, which is what the shade guide is for.

Whitening works on natural enamel and nothing else. A cavity, worn enamel or gum disease is a reason to treat first and whiten second, and a crown or a veneer will not change shade at all. A dentist can see every one of those before any gel goes on. A store-bought kit does not include that exam.
The kind of whitening you get is chosen to fit your mouth.
An exam shows whether whitening will suit your teeth, and that is better known before you buy anything.
It can, with either method. Whitening gel passes through the enamel, and some teeth react to that with a brief ache or a sharp edge to hot and cold. It is more likely if your teeth are already sensitive, so say so before you choose. With a take-home kit you can ease off when your teeth tell you to; in the chair, say so the moment something stings.
It is not permanent, and how long it holds is mostly down to what your teeth meet afterwards. Coffee, tea, red wine and tobacco all stain again, and brushing well and keeping up with cleanings keep stain from settling back in. Nobody can promise you a length of time.
No. Whitening works on natural tooth enamel, so a crown, a veneer or a tooth-coloured filling keeps the shade it was made in. That matters most for front teeth: if you have work there, the natural teeth beside it will lighten and it will not, and it is far better to know that before you start than after. Mention any dental work when you call and it can be looked at first.
Earlier than feels necessary. Leave room before the photo date rather than whitening at the last minute, so that any sensitivity has time to settle and a second round is possible if you want one. In-office whitening is the faster of the two, so it suits a closer date, but call early whichever you choose.
