Boutique Teeth Whitening

[pandorawithtreaclecolouredhair]

Went to the dentist today for usual hygienist and dental check up, and saw a poster in the waiting room advertising Boutique teeth whitening.
The dentist took a mould for a mouth tray, and I have an appointment to return for instructions and tray and gel.
Might have to have a new front crown fitted if the new whiteness doesn't match it.
Anyone had this treatment, and how were the results?

I've used it, works brilliantly. Don't use them for more than suggested, 4 hours? It can make your teeth really sensitive if you over do it, and wipe of any excess bleach from your gums.

I had yellowy teeth and they are white now. I haven't used up all four tubes yet. I'm a dental nurse and would definitely recommend it.
