Q. Hi, I am thinking of having some kind of treatment to straighten my teeth, and am not sure about which route to take. I am currently considering both cosmetic and orthodontic procedures. I have spoken to my dentist, who has been really unhelpful, and pretty obstructive, refusing to talk about either option, saying she isn’t qualified. She refused to answer even the basics, like would I be able to have invisible braces fitted? She has referred me to an orthodontist, but this will cost me £100 for the initial consultation. My question really is, I am 30 years old – how long is it likely that I would have to have fixed braces on for (presuming that this is the only option for me). I think that my teeth are over-crowded, so it’s likely I would have to have teeth out. I was told by an old dentist that I had an overbite of 7mm. If I had to wear this for 2 years or more, I may consider cosmetic work. Can you give me some rough approximations on cost for 4 front teeth straightening? Also can you tell me what is involved with cosmetic work?
