Q. To Dr Caplan I am going to be 18 in a week and a halfs time, and have been worried about my teeth and the appearance of my teeth from a very early age. I had “goofy teeth” – which got corrected with braces which i had when i was 13. However there other things happening, e.g.. when i was ten, i fell down and broke one of my front teeth, and had it filled out.. in which you couldnt tell that much that half of it was not real. Hoever when i had braces, it caused an abscess, and the root of the tooth was dying.. and turned dark grey.. and died. the appearnce of my grey tooth this year has been improved by firstly having re root canals twice early this yr, and then a bleaching process which i was quite happy with comparing it to the darkness before. I am now more concerned with the gaps i have around my upper teeth, ( i took my braces off around 3 or so yrs ago- however.. later on after my retainers i was still having problems with my dead tooth…and stopped wearing my retainers only after my orthodontist told me i could stop wearing them) and since.. i have tiny gaps between my front 6 teeth.. and a slightly bigger gap in between my front teeth which has made my uncomfortable to smile ifront of.. and talk to other people. I have thought about getting invisalign, though i looked at the price of an orthodontist fees aroun my area.. and i believe it said from £4,000 which i was shocked to see! .. im still 17 but im sure by the time i would get treatment it would not be viable through the NHS.. to even get braces. i’m unsure on what to get.. and ive been reserching on invisalign.. and trying to find out if it actually worth it, as it is very expensive- i know its hard to judge a course of treatment from an email,.. but was wondering whether you could perhaps suggest one nonetheless and give me some helpful advice. Thankyou and apologies for the very long email!
