food for teeth ? Answered
Hello. I've heard that teeth were able to absorb some substances/molecules thanks to the porosity of the enamel. Unlike bones, as they are not self-regenerating from the outside, I was wondering what substances may be usefull to offset the erosion of the enamel (remineralization ?). Is there something that could be concidered as a "food" for teeth ? Also, about dental caries, as they are mainly caused by bacteria eating "fermentable carbohydrates" who generate acidity, here is a question that may sound stupid, but that is serious : - to make the work of those bacteria harder, is it better to sleep with the mouth wide opened (oxygened mouth) or with the mouth closed (anaerobic conditions) ?
