Hello Dr, I am 42 years old and i continuously brush my teeth yet they keep on rotting and i do not know why. I brush my teeth in the morning and before i go to my bed. I have filled many of my teeth. Please help me. I brush my teeth in multiple ways, like circles and up and down an side ways. All of my mother’s teeth have fallen out and she has dentures in and also my brother. I am really distraught and would like to know what could be the cause of this because my confidence is being affected quite badly and I’m scared of what could happen in the future considering my mother and brother’s situations. Thank you, looking forward to your response.
