Bad, no. Obsessive Compulsive, yes. But at least you'll have white teeth and a bright smile.......
I might do a Beto-type video in the future about visiting my dental hygienist. She worked on my teeth cleaning when she was a student at a dental school and told me I had the HEALTHIEST teeth of anybody she ever saw then (and since). NO cavities and NO fillings. Genetic. My father also had the same healthy teeth plus my teeth are basically duplicates of his teeth since we both have the same small size teeth that are incredibly durable.
Maybe. It turns out that the effects of toothpaste ‘whiteners’ which make just-brushed teeth look whiter in the bathroom mirror, wear of by the time you get to work.
