Can you smoke with a spring retainer in?

Smoking: smoking is unhealthy at anytime and I would suggest that you speak your dentist and he would probably tell you that it's not a good idea

Smoking: Smoking irritates oral tissues, making tooth position correction less successful and less stable. Smoking causes oral cancer, lung cancer, shortens your life, stains your fingers, stains your teeth, prematurely ages your facial skin, gives you bad breath, allows the bacteria that cause gum disease to be more effective. Now would be the perfect time to quit.
