Q. I have always had terrible oral hygiene since a child because I refused to brush my teeth. I am now 21 years old and I am now starting to pay the price. My front tooth has a big chip in it, the next tooth has a huge chip behind it, I’ve recently lost half of of a premolar and I’ve had to remove a molar for also losing half of it. My teeth are also very off-coloured , I have black stuff just where the tooth meets the gum, my bottom gums are starting to get a little black growing on it and I have terrible breath. I really want my smile back so I can meet girls again and be happy without feeling embarrassed about my hygiene. What kind of treatment would I have to undertake to fix my rotting teeth and bad breath?,
