How can I whiten my teeth?: Dr Pratish Dholakia, Dentist
There's two different ways to whiten your teeth. There's what we call the 'office whitening' or 'power whitening'.
It's basically an in-surgery treatment, it takes about an hour to two hours. What we do is we paint a special gel on to your teeth. Shine a blue light to activate the gel. Leave it on for 15 minutes. Wash it off, another layer, 15 minutes, wash it off. You have three or four applications during that space of time. The advantage of that is you have instant whiter teeth there. Disadvantage is you're sat in the chair for an hour or two hours - that can be a bit uncomfortable for some patients with their jaws. And the other disadvantage, is you may get some sensitivity, and that varies from patient to patient.
The other method is the one where we do it at home, where we will take moulds of your teeth and make some special trays that fit your teeth. You basically squirt some gel into the trays, pop it on to your teeth, wear it for anywhere between half an hour and four hours a day. Advantage of that, is it is at your own convenience. Far less instances of sensitivity and if you keep those trays in a safe place you can use those trays to do a top-up stage down the line.
