Q. Hi, I am 21 years old and have an 18 month old daughter. over the past few years my teeth have started to rot away and can sometimes be very painful. i cannot remember the last time i went to the dentist as i have a fear of going there. at the moment i have lost a tooth on the top row and now have only a quarter of a tooth that did originally have a filling. i have noticed when i brush my teeth on the bottom row i can now c through a tooth and see the gums beneath which really shocked me, as i did not know how bad they had got. Please can you recommend anythin which is not too expensive that can help me please?,
