Happy Teeth Dental Center offers prescription strength whitening kits for patients. These include custom made take-home trays, which you can use in the comfort of your own home. Dental whitening doesn’t harm your teeth or remove enamel but your teeth may become more porous and sensitive in the process. It is imperative that you avoid coffee, sodas, red wine, cigarettes, and anything that can stain your teeth when you start your treatment and for 2 weeks after you finish. All whitening treatments require an exam, x-rays, and cleaning before beginning. To see if you’re a candidate for dental whitening, inquire with your dentist.
