Full mouth teeth whitening by Dr. Andre Singer, DDS. Dental office located at 7810 17th Avenue in Bensonhurst Brooklyn. He will fabricate custom bleaching trays and provide a powerful bleaching agent. The procedure involves bleaching your teeth at home daily for 30 minutes for approximately 7-10 days until you achieve the shade you desire.  The home bleaching system is far safer than an in office bleaching system. If a patient encounters cold sensitivity, you stop bleaching your teeth for a few days. An in office system can result in extreme cold sensitivity.
