My 12 yo son has just seen the orthodontist. His canines are much higher up than the rest of his front teeth, and his bottom front teeth are seriously wonky. But, as not a single one is more than 4mm out of line (3 mm in 2 places doesn't count) it's not on the NHS. My son doesn't see the point: all that effort and who needs a beautiful smile? And his teeth may get decay earlier, but hey, they may not. I think most people nowadays do have beautiful smiles, and he doesn't realise people judge you for this. Besides, it's not just 1 wonky tooth, these canines really define his smile. Do I make it compulsory? How to convince him? Or is it just not important?
