I have noticed recently that the gums around the 2 pre-molars on my bottom teeth seem to have receded quite a lot. On one side the tooth itself feels a bit sensitive. The tooth is not smooth between the tooth and gum.
I had bleeding gums in pregnancy a few years ago but nothing since. My last check up was last February and the dentist saw no problems.
What can I do to prevent them receding further? And can I do anything to make them better?
