My partner recently noticed and told me that my gums have receded quite badly and that I need to be careful with how hard I brush my teeth. I've never noticed this before but since it's been pointed out I can't stop checking them and have realised that he is right and they do look quite badly damaged. I'm 24 and take good care of my teeth but haven't been to the dentist in a while due how expensive it is now to even just book a check up! I'm becoming increasingly worried but with having nothing to compare them to I feel quite clueless as to whether they are as bad as I'm thinking they are and if I should even be worrying about tooth loss any time soon! Here is a picture of my teeth and gums for anyone to assess and tell me if they are as and as I'm beginning to think!
Any help and advice is greatly appreciated!!
