I have been helping patients whiten their smile with bleaching systems for over 20 years. In the last two years, I have been offering a new system, called the KoR Whitening System. This process includes bleaching in the office and at home. The results have been absolutely astounding. After the bleaching results have been attained, it is recommended to bleaching once monthly at home to maintain the lighter shade. Patients with very dark teeth and staining have attained changes I have never seen prior to using the KoR bleaching products.#fb
