Hello. I would like one of my lower front teeth to go back in line with the rest as it is indented. I have been told that I could wear an invisible brace (removable) for 6 month at a cost of £2,600. Would that cost be about right? Also, my husband has the same problem except his problem tooth is on the top set of teeth.  His tooth has protruded slightly more than usual over the last couple of months and so he too has been told that an invisible brace could be fitted and would solve the problem in 6 months at a cost of £2,600. Please give some advice. Thank you, Dr Shaffie.
