A few years back I did this, using specially moulded mouth trays and gel. I need to do it again now, but the gel has escalated in price, plus chances are I would need another mouth tray made, because teeth do move slightly, and that's the most expensive part.
I always thought shop bought tooth whitening kits were rubbish- I remember DD messing about with one and not seeing any results - and also I've been scared off laser whitening.
However, am I right in saying that the over the counter kits are now much better quality? And that laser whitening (although probably expensive like mouth trays) is also much better/safer these days?
Would be great to hear anyone's thoughts!
