Yes after three full days of dental hygiene I’m am tired of teeth work and smelly stuff. The teeth are not the only thing that smell sometimes I’ll get a big whif of sweat smell I’m thinking it’s me. I cleaned the teeth of a 9 year old who had never brushed her teeth ever. It was bad. I talked with her father and said she needs to brush or there is a high probability she will loose her teeth. If she loses her teeth she may end up not married, this is very serious, it is much harder to be independent in a poor country, than in the United States.
