All my life I've brushed my teeth 2 or more times a day. I've flossed every day. I've used mouthwash every day. All my life whenever I would go to the dentist every 6 months for my cleaning I'd have 2 or 3 cavities I'd have to come back & get filled. For the last year & a half I've done a test. For 1 year I stopped using mouthwash altogether. I only flossed if I felt like I had something stuck in my teeth. I only brushed my teeth if I was my house (sometimes every other day), or if I felt like I just had to. For 2 cleanings in a row I had absolutely no cavities! For the last 6 months I started brushing, flossing & mouth washing as usual & guess what? 3 cavities! What's up with that!
