First off, the suction can be bad for the healing process...this goes for tobacco and cannabis alike. Secondly, cannabis dries the mouth which is a bad thing when you are healing. It concentrates the bacteria that every mouth has. I had most of my teeth pulled a few years ago, and yes, I smoked as soon as I got home from the dentist. I also kept my mouth moist by lots of drinking liquids (mostly water). Roll your joints looser than normal so you won't need as much suction and drink liquids! Everything healed up just fine. - Granny:hippy:
