My teeth are looking yellow and I'm getting very self conscious about smiling and talking now. I've started to buy tooth whitening strips from the supermarket and expensive whitening toothpastes but I am not seeing much improvement.
I think need to do something more drastic, but I am a bit confused. I read something about a tray you use each day for a couple of weeks. I think they sell them online and so I'm wondering if I can buy one of those things and if it's better than going to the dentist, or if it's better to go to my dentist? And would the dentist be a one off thing, like go in, they do their magic and I walk out with white teeth? Sorry am clueless, any advice appreciated.
