Q.
Dear Dr. Solanki, I have been told I have tetracycline stained teeth due to acne treatment. I had Zoom whitening treatment almost 2 years ago which did lighten them somewhat but the effect did not last. I have trays to use at home ‘nitewhite’16% (now out of date). How often should I have used the home treatment (I sleep badly so prefer not to use them at night), I did not want to use them often as I worry that I will harm my teeth/gums. Does whitening actually work on tetracycline staining and if so how often is it safe to have the treatment? Alternatively is there a more effective treatment than Zoom. I don’t want to go down the Laminate route due to expense and damage to teeth. I will be most grateful if you would advise me. Kind regards
