I had my teeth whiten at the dentist a little over a year ago. I am a light smoker but have been tyring to quit and only smoke once or twice a week which compared to what I use to do almost a pack every two to three days I have made really good progress.
My question is that although my teeth are still white they are not as white as they use to be when I first had the whitening treatment done. Should I go back to the dentist to have them re whiten or wait until I am able to fully quit smoking altogether. Which I am weening off and hope to be done with smoking in another few months. What would be best?
