One of the best things about your aligner trays is that they’re invisible. Smoking will discolor them, so it is best to not smoke with your Invisalign trays in your mouth. Of course, you still need to wear them for 20 to 22 hours per day, so a regular smoking habit might interfere with Invisalign treatment. You do receive new trays every two weeks or so, therefore, you may be able to negotiate this matter successfully. Consult with the dentists at our Carmichael office to determine if Invisalign and your particular smoking habits can coexist successfully. If not, we could use traditional braces to solve your orthodontic problem.
