My dentist feels that I should see a specialist because I have gum disease, but I feel nothing and my gums do not bleed. Is it possible that I still have periodontitis?

People may  have periodontitis and not know it nor feel it One reason for that is that usually the first symptom of periodontitis is gum bleeding during toothbrushing which many people think as normal. If you think that your gums do not bleed and still your dentist feels that you have periodontistis, it is possible that you would expect to see tones of blood to come out for teeth while you brush. Whereas what you should expect to see it is usually only some drops of blood on teeth after brushing. And that is still pathologic.

Moreover if you are a smoker the symptom of gum bleeding further reduces because smoking causes vasoconstriction.
