What if I told you that a cheap, effective and painless method of stopping tooth decay had just been invented! You’d be pretty happy. What if I told you that a cheap, effective and painless method of stopping tooth decay was invented over 100 years ago and has been available in other countries for decades but only now is it starting to be used in the United States as a non-FDA approved, off-label treatment?
Studies show silver diamine fluoride stops decay in 60 to 70 percent of cases with one application. A second application six months later boosts the treatment’s long-term effectiveness to more than 90 percent.
In addition to killing cavity-causing bacteria, the treatment hardens tooth structure, desensitizes the tooth and even stops new cavities from forming. Applying the liquid on the exposed root surfaces of older adults once a year is “a simple, inexpensive, and effective way” to prevent cavities, a 2018 study concluded.
