A4Perhaps you came to this article expecting suggestions for oil pulling, apple cider vinegar rinses, and baking soda scrubs. The ADA’s position on DIY teeth whitening treatments is that they do more harm than good, and we agree. Often these treatments remove surface stains, which makes you think that they’re working; what you don’t see is that they’re also eroding your enamel in the process and in the long-term, this will cause yellower teeth. Stick with professional teeth whitening, ADA-approved products, and good oral hygiene for the best results.
