Q. Dear Dr Justin Glaister, Well, I do not know where to start. Firstly I have to get rid of my wisdom teeth (the pain is killing me), and then I have a problem with basicly all my other teeth. My teeth will start breaking bit by bit, starting near the root, and it hurts badly, I have about 10 teeth that is broken. I could not eat for the past few days and whenever I drink hot or cold drinks it hurts. My dentist in south africa said that it is a shortage off calsium. I had this problem since I was 14 (now 22). I live in Swanage, Dorset, England, BH191AN. Is there any advise you can give me in this matter? Regards,
