I have chronic periodontitis and have recently been to have a deep clean. My Dentist said that my gum pockets are quite bad between 4-8 cm I am doing everything that I can to keep it under control. I don't smoke, clean twice a day, waterpick and floss, but my gums still swell and bleed occasionally in just one place. I have asked my dentist to refer me to a specialist, as the local dental hospital would not accept me. It is looking very likely that I will have to go private. Can anyone recommend a good Gum Specialist, in Greater London that will not bankrupt me.
