Hi I have a front upper tooth chipped (a nip underneath when I was hit with a stick many years ago- only mentioning this in case you think I don’t look after my teeth) I have had it repaired with something that was bonded onto it although it still shows a hair crack line where the join is barely visible unless seen close up. Would it be better to have a veneer or a crown as regards longetivity and if so how much will it cost? Also out of interest are there any technological advances better than lumineer or other long term solutions I heard a while back in the papers that a technique was being innovated whereby a whole tooth could be re-grown somehow. Many Thanks!
