I purchased this product because my husband has dry mouth and is always looking for something to help him with it. He had the original oral b sonic toothbrush since they were first introduced. It lasted 10 years until we finally tried out a more modern electric dental brush. This newer version was too weak for him, he can't get enough vibration that makes his teeth feel clean, so back it went.
