Q. Hi sir, I am 27 and I feel very anxious about my bottom two teeth thinning. I often feel a strange sensation (not pain but sort of sore) with these teeth..and feel like I need to chew something. As I child I never drank much milk but I have now started to drink at least 2 small glasses everyday and sometimes take vitamin D and calcium supplements. Is there anything more I can do to protect my teeth? I am still young and want my teeth to last me a life time. Please advice. Much appreciated, Has
