I had mine on for about two years, and I'm supposed to wear retainers after that but the things aren't helping so I just sort of gave up. Ugh. Waste of money, honestly.

There's nothing much you can do about it at the beginning stage except drink liquids and stuff, though.

Er... I can't really help you, seeing as I've always been lucky enough not to get braces. But I did get fillings on my teeth when I was six (something about there not being enough fluoride in the water resulting in me getting cavities...).

Then, I ate nothing but chocolate pudding for two days straight.

Sorry...
