FluorosisQuestion:

Sherry, RDH, asked: Is fluoride varnish recommended for patients with fluorosis? Thank you!

Answer:

Thanks for the question, Sherry!

According to the American Academy of Pediatric Dentistry’s Guideline on Fluoride Therapy, “Decisions concerning the administration of fluoride are based on the unique needs of each patient, including the risks and benefits (i.e., risk of mild or moderate fluorosis versus the benefits of decreasing caries increment and, in some cases preventing, devastating dental disease).” (1) As we know, fluorosis occurs when developing enamel is exposed to excessive quantities of fluoride. Most cases of fluorosis occur from ingestion of too much fluoride, whether by fluoride supplements, overfluoridated drinking water, fluoridated toothpaste, or some combination of these. The risk of developing fluorosis is greatest before eight years of age, when the teeth are developing and enamel is being mineralized. (2) Of course, we do not know if a patient has dental fluorosis until the teeth erupt. When treating patients younger than eight years of age, clinicians should counsel caregivers on fluoride supplementation after considering the level of fluoride in the drinking water in that area. Parents should also be directed about the proper use of fluoride toothpaste for young children in order to avoid overconsumption. The American Dental Association's fluoride toothpaste recommendations are a smear the size of a grain of rice for children under three years of age and a small, pea-sized amount for children three to six years old. (3)

When applying fluoride varnishes, clinicians focus on patients with moderate to high caries risk. While each patient has different host and home-care factors, many patients with fluorosis are less susceptible to decay due to the overabundance of fluoride.

In the end, adolescent and adult patients with fluorosis may have low risk of decay and may not require fluoride varnish or an in-office treatment. However, this decision should be made on a case-by-case basis, and if the patient exhibits moderate or high caries risk, there is no additional risk of fluorosis by performing a topical fluoride varnish.
