My front two teeth were bonded after a collision with a surf boat rowing oar five months ago (I now wear a mouthguard), since then I had them repaired and then they chipped, got that fixed now but now its happened again for absolutely no reason, I'm really unsure as to whether I go back to this dentist get them fixed the same way or what I do. I'm only 17 so I don't want to have to keep doing this until I have enough money for something stronger.
