This readily available liquid is effective for treating and preventing dental cavities

A recent study conducted by researchers at the New York University College of Dentistry reveals the effectiveness of an inexpensive liquid in combating dental cavities in elementary school students. This liquid, known as silver diamine fluoride, is found to be just as effective as dental sealants in preventing cavities, according to the study published in JAMA Pediatrics.


Dental cavities represent the most widespread chronic disease among children, leading to pain, school absences, and decreased academic performance. To combat this issue, dental sealant programs in schools are generally encouraged. These programs involve the application of a protective coating on teeth, administered by dental professionals.

However, silver diamine fluoride emerges as a promising alternative. Initially approved by the FDA for treating tooth sensitivity, this liquid is also found to be effective in eliminating bacteria responsible for cavities and remineralizing the enamel to prevent new cavities.

The study followed more than 4,000 elementary school students for four years. Conducted in New York City schools, it compared the effectiveness of silver diamine fluoride with that of traditional sealants. The results, published in JAMA Pediatrics, demonstrate that silver diamine fluoride prevents as many cavities as sealants, thus offering an economical and effective alternative in the fight against cavities.

Ryan Richard Ruff, Associate Professor of Epidemiology and Health Promotion at New York University, states that silver diamine fluoride can not only halt the progression of cavities but also prevent their onset. This research paves the way for a more inclusive and accessible approach to pediatric dental care.
