Hi Fagin

Teeth whitening is one of the best ways to get your teeth whiter and enhance your smile.
There are two types of systems
1-Power whitening (laser) - at my practice in Surrey, we use 1 hour Zoom -advanced power - very reputable

2- Home whitenng - bespoke trays made in which you place the whitening gel in the tray and then wear the trays for at least 3 hours at a time.- this can take up to 2 weeks

The results and what system best suits you is usually assessed at your initial visit. It does also depend on the inital colour of your teeth as greyer teeth are more difficult to whiten than yellower based teeth. With the Power whitening you can achieve up to 10 shades lighter!

How long it lasts, as Pagdeep mentioned is dependant on you lifestyle and this would determine how often you top up. Most commonly once every 6 months or so.

Many practices have whitening procedures on special offer as they are so popular.

I hope this helps
