My dentist is advising periodontal treatment as he says I have gum disease. When checking my teeth he regularly calls out numbers too his dental nurse, the majority being 1s and 2s with a couple of 3s. My gums appear to me to be pink and healthy, they have not bled for a long time. I brush twice daily and use an electronic flossier twice daily. I am highly suspicious that he is trying to drum up business, £275 plus 6 mthly maintenance checks. Is there anyone out there that can give me independent advice?
