Is Silver Diamine Fluoride as Effective as Dental Sealant?

Boy at the dentist

When it comes to protecting children’s teeth from cavities, dental sealants have long been the gold standard. But in recent years, silver diamine fluoride (SDF) has emerged as a strong alternative, especially for patients who need a non-invasive, quick solution. Several studies now suggest that silver diamine fluoride may be just as effective as dental sealants in preventing cavities. So, what does the research say, and how do you know which option is right for your child or yourself?

What is Silver Diamine Fluoride?

Silver diamine fluoride is a topical liquid that combines the antibacterial properties of silver with the remineralizing effects of fluoride. It’s painted directly onto the surface of a tooth to stop or prevent cavities, especially in hard-to-reach areas or in patients who may not tolerate traditional dental procedures.

Unlike sealants, which form a physical barrier, SDF works by killing bacteria and hardening weakened enamel. It’s painless, fast, and doesn’t require drilling, making it particularly useful for young children, seniors, and individuals with special healthcare needs.

What the Research Says

Recent studies have begun to compare the long-term effectiveness of SDF with that of traditional dental sealants. A particularly influential study published in JAMA Network Open in 2021 evaluated children in school-based oral health programs. Researchers found that SDF was non-inferior to sealants in preventing tooth decay over a two-year period. This means SDF performed just as well as sealants in reducing the occurrence of new cavities.

Another study from the Journal of Dental Research reinforced this finding, showing that biannual applications of SDF significantly reduced the development of new carious lesions in primary teeth. The researchers emphasized SDF’s potential as a cost-effective and accessible alternative to sealants, especially in underserved communities.

Advantages of Silver Diamine Fluoride

  • No drilling or numbing needed: Great for anxious patients or young children.
  • Quick and painless application: Takes only a minute or two per tooth.
  • Affordable: Often less expensive than sealants.
  • Accessible: Ideal for community and school-based dental programs.

Drawbacks to Consider

The most notable downside of SDF is staining. It turns active cavities a dark brown or black color, which can be cosmetically unappealing, especially on front teeth. However, this isn’t an issue for its preventive use on back molars, where it’s often applied instead of a sealant.

Should You Choose SDF or Sealants?

The choice depends on the patient’s age, oral health needs, and comfort level with dental procedures. For patients who are cavity-prone but unable to sit through traditional treatment, SDF offers a highly effective, non-invasive option. For others, especially those concerned about discoloration or aesthetics, sealants may still be the preferred route.

 

Silver diamine fluoride is proving to be more than just a temporary solution—it’s a legitimate preventive tool supported by growing scientific evidence. As studies continue to highlight its effectiveness, especially in school and community settings, SDF may soon become a go-to choice alongside traditional dental sealants.
