My dentist gave me the high end sonic care for free. Probably because after the bloody horror of a deep cleaning, they didn’t want to have to wade through that mess again.
Even though I brushed all the time, my gums were being destroyed by bacteria. But 6mo after a deep clean and proper maintenance, I dind’t even bleed once from a follow up cleaning. My dental hygienist was ecstatic at how much better it was. Lesson learned, even if it doesn’t hurt, go to the dentist for maintenance.
