I think I understand the question. I purchased an electric toothbrush and the vibrations started up an abcess that probably would not have happened had I have been using an ordinary toothbrush. My friend who is a dentist thought the electric toothbrush was finding a weakness in a tooth and worrying it enough to start the abcess. Her advice was to go back to a normal toothbrush and leave the battery ones alone. My advice would be a good Wisdom toothbrush, decent toothpaste and a good mouthwash.
