That article has little about self-care for teeth. ATMI the “standard” three things recommended by dentists are brushing (using a tooth brush and tooth paste), flossing, and daily “swishing” of mouthwash in one’s mouth. Something I discovered a few years ago should interest many: I discovered that I can make a black area of delay disappear (become a brilliant white) by daily painting the spot with ethanol (drinking alcohol). The mouthwash sold in stores seems much to weak to achieve such a result.
