Q. Hi I am a healthy and fit 52 and for all my life have had a small gap between my 2 top front teeth. However over the last 6 months or so the gap has widened so far that I can get my tongue in between them! I have been to my dentist who said that she cant see why as I have no sign of gum disease and have healthy teeth. As I cant find an NHS dentist she siad she would refer me to an orthodentist but this is going to cost i just know it!!!I am not that worried about the gap itself butr am concerend that there is something causing it that I should be concerend about. Any suggestions? and also is there any way I can be referered for NHS treatment by my GP?
