My friend brushes his teeth 2-3 times a day (sometimes more but never less). He uses a Philips Sonicare toothbrush which is supposed to be gentle on teeth. He also grinds his teeth in his sleep, and uses a mouthguard at night. When he brushes, he does it with his Sonicare for at least 20 minutes, sometimes a lot longer. This time does not include the flossing and rinsing. All in all it is usually at least an hour long ritual. He mostly uses regular instead to whitening toothpaste because it's less harsh on enamel. He claims if he doesn't brush his teeth so long, they become gray. He does also complain sometimes about his teeth being sensitive, and his dentist has reccomended using Sensodyne toothpaste. When you take into account how many times a day he brushes, and for how long, it's about an hour of scrubbing on those teeth daily, when most people spend maybe 10 minutes brushing a day. How can I convince him this is harmful? I need reputable sources.
