People generally say they are not that bad but I know they are, the bottom ones are hard to clean behind and get a build of hard plaque behind them, I try my best and floss every day but the brushes don’t fit in all the gaps.
This is what I meant when I said your teeth could be prone to getting decayed and you could get gum disease. Sorry you are going through this: I hope you get help. 
@Shellyboobs
People can't even get bloody fillings done on the NHS to fix acute dental pain in many areas.
And what bollocks about 'do you pay tax, NI...' Around 50% of tax payers get more out than they put in, so don't try to make out entitlement to free treatment should be dependent on paying in.
OP, I'd recommend seeing a good orthodontist as others have mentioned, but to be quite honest it's a bit off to be declaring that you can't possibly get married because you couldn't bear to have photos done. Spare a thought for other people with fair greater 'aesthetic issues'.
Jesus. Have you had a bad day or something?!
What an unpleasant post. There is no need to be so rude and snarky. I am only trying to help, and make the OP feel better. And no need to be so rude to the OP either by saying some people have WORSE problems.
There are a few people on mumsnet who could start an argument in an empty room. 
IMO, the OP deserves to get the treatment on her teeth on the NHS. Her teeth look like she will have lots of problems with decay in the future. She is as entitled as anyone else. FFS, people have boob jobs and gastric bands on the NHS. Why the hell should she not be allowed treatment on her teeth?!
If you don't think so, then fine, but there is no need to be so rude.
Sorry if you have had a bad day. Hope tomorrow is better for you.
