I haven't really got any big issue. My teeth are just going a bit yellow. Not pleased. I've always had a bright smile but it seems that's no longer really the case. I love the 'shape' and straightness of my teeth so didn't want veneers 
However, a friend of mine has a husband who's a dentist. She said whitening at a dentist won't really do anything, and the only way to get white teeth is to get veneers.
I thought you could get them bleached at a dentist but apparently it just doesn't work.
Can anyone point me in the right direction? Not bothered about things like bonding for teeth since I like how they look apart from their colour now
