Q. I didn’t want braces when I was younger, but now have teeth that are too big and crowded for my mouth. I am now 24 and have both and overbite and underbite. My middle two top teeth (bunny teeth) have pushed forwards even further and one is now crossing over the other due to lack of space. I find it very difficult to close my mouth, which makes eating, talking and sleeping difficult (I sleep on my face to keep my mouth shut so I can breathe properly). Where I am stretching my jaw to close my mouth, I am getting pains in my neck and ears and I would like to get my teeth fixed before things get any worse. My teeth are fairly straight and otherwise healthy, but too far forwards in varying degrees. I have had all four wisdom teeth removed this year. I work full time in an office and having a metal brace would make my job very difficult (I have to talk to clients) as I alerady find it difficult to talk. I am therefore considering getting invisalign to pull my teeth back. Could you give me more information on this. What is involved, roughly how much is it likely to cost and how long will it take to work? Will it make talking more difficult as a metal brace would?
