There are many oral care products on the market with proven clinical benefits. They include fluoride toothpastes, toothpastes containing anti-plaque agents and a range of antiseptic rinses. There are also products that might help your oral health but which have little or no evidence to support them such as calcium, magnesium, vitamins C, D, B12, and herbs like curcumin, and probiotics. They are, however, used by millions of people at the recommendation of their dentist.
You should look to see if a product is endorsed by the American Dental Association to give you the confidence that the product is safe and effective.
