Time to quit?
With few exceptions, smoking and gum disease go hand in hand. Smoking makes plaque much more aggressive to the gums.
It also reduces the blood supply to the gums (vasoconstriction) which means that the effects of the body’s own immune defences are compromised. If you smoke, it is very important that you keep your teeth and gums very clean.
Of course, the best advice is to quit.
