Q. I am a 21 year ol mother of two and my teeth have been beautifully straight and healthy up until the pregnancy of my second child, now they are always getting chipped and the enamel has worn very very badly. I am a smoker and my teeth have became discolored i am wondering if i would be able to get vaneers or something on the NHS to sort out the awful mess they have got into as i am embarressed to smile and getting married next year!
