0.2% Neutral Sodium Fluoride



Wentworth Sodium Fluoride Rinse 0.2% of neutral sodium fluoride is a mint-flavored, neutral, aqueous solution.

Active Ingredient

Sodium Fluoride 0.2% (w/v)

Inactive Ingredients

benzoic acid, flavor, glycerin, poloxamer 338, propylene glycol, sodium benzoate, water, FD&C Blue No. 1


Topical application of sodium fluoride increases tooth resistance to acid dissolution, promotes remineralization, and inhibits the cariogenic microbial process.

Wentworth Alcohol Free Indications and Usage

A dental caries preventive, for weekly self-applied topical use. Weekly rinsing with a neutral 0.2% sodium fluoride solution protects against dental caries in adults and pediatric patients. Wentworth Sodium Fluoride Rinse provides a ready-to-use preparation for convenient administration and favorable compliance. May be used in areas where drinking water is fluoridated since topical fluoride cannot produce fluorosis. (See WARNINGS for exception.)


Do not use in patients with dysphagia. Do not use in pediatric patients under age 6 years unless recommended by a dentist or physician.


Keep out of reach of infants and children. Pediatric patients under age 12 should be supervised in the use of this product. Patients under age 6 require special supervision to prevent repeated swallowing of rinse since they frequently swallow significant amounts while rinsing. Prolonged daily ingestion may result in dental fluorosis in patients under age 6, especially if the water fluoridation exceeds 0.6 ppm. Read directions carefully before using.




Not for systemic treatment. DO NOT SWALLOW.

Carcinogenesis, Mutagenesis, Impairment of Fertility

No carcinogenesis was found in mice or female rats treated with fluoride at doses ranging from 4.1 to 9.1 mg/kg of body weight. Equivocal evidence of carcinogenesis was reported in male rats treated with 2.5 and 4.1 mg/kg of body weight. In another study, no carcinogenesis was observed in rats treated with fluoride up to 11.3 mg/kg of body weight. Epidemiological data provide no credible evidence for an association between fluoride, either naturally occurring or added to drinking water, and risk of human cancer.

Fluoride ion is not mutagenic in standard bacterial systems but has been associated with chromosome aberrations in cultured human and rodent cells at doses much higher than expected human exposures. Some in vivo report chromosome damage in rodents while other studies using similar protocols report negative results.

Potential adverse reproductive effects of fluoride exposure in humans has not been adequately evaluated. Adverse effects on reproduction were reported for rats, mice, fox, and cattle exposed to 100 ppm or greater concentrations of fluoride in their diet or drinking water. Other studies conducted in rats demonstrated that lower concentrations of fluoride (5 mg/kg of body weight) did not result in impaired fertility and reproductive capabilities.


Teratogenic Effects

Pregnancy Category B

It has been shown that fluoride crosses the placenta of rats, but only 0.01% of the amount administered is incorporated in fetal tissue. Animal studies (rats, mice, rabbits) have shown that fluoride is not a teratogen. Maternal exposure to 12.2 mg fluoride/kg of body weight (rats) or 13.1 mg/kg of body weight (rabbits) did not affect litter size or fetal weight and did not increase frequency of skeletal or visceral malformations. There are no adequate and well-controlled studies in pregnant women. However, epidemiological studies conducted in areas with high levels of naturally fluoridated water showed no increase in birth defects. Heavy exposure to fluoride during in utero development may result in skeletal fluorosis which becomes evident in childhood.

Nursing Mothers

It is not known if fluoride is excreted in human milk. However, many drugs are excreted in milk, and caution should be exercised when products containing fluoride are administered to a nursing woman. Reduced milk production was reported in farm-raised fox when the animals were fed a diet containing a high concentration of fluoride (98-137 mg/kg of body weight). No adverse effects on parturition, lactation, or offspring were seen in rats administered fluoride up to 5 mg/kg of body weight.

Pediatric Use

The use of Wentworth® Sodium Fluoride Rinse as a weekly caries preventive in pediatric patients aged 6 to 16 years is supported by adequate and well-controlled clinical studies in students aged 6 to 12 years.1-4 Safety and effectiveness in pediatric patients below the age of 6 years have not been established. Please refer to the CONTRAINDICATIONS and WARNINGS sections.

Geriatric Use

Of the total number of subjects in clinical studies of 1.1% (w/v) sodium fluoride, 15 percent were 65 and over, while 1 percent were 75 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

Adverse Reactions to Wentworth Alcohol Free

In patients with mucositis, gingival tissues may be hypersensitive to flavor present in formulation. Allergic reactions and other idiosyncrasies are rarely reported.


Accidental ingestion of large amounts of fluoride may result in acute burning in the mouth and sore tongue. Nausea, vomiting, and diarrhea may occur soon after ingestion (within 30 minutes) and are accompanied by salivation, hematemesis, and epigastric cramping abdominal pain. These symptoms may persist for 24 hours. If less than 5 mg fluoride/kg body weight (i.e., less than 2.3 mg fluoride/lb body weight) has been ingested, give calcium (e.g., milk) orally to relieve gastrointestinal symptoms and observe for a few hours. If more than 5 mg fluoride/kg body weight (i.e., more than 2.3 mg fluoride/lb body weight) has been ingested, induce vomiting, give orally soluble calcium (e.g., milk, 5% calcium gluconate or calcium lactate solution) and immediately seek medical assistance. For accidental ingestion of more than 15 mg fluoride/kg of body weight (i.e., more than 6.9 mg fluoride/lb body weight), induce vomiting and admit immediately to a hospital facility.

A treatment dose (10 mL or two teaspoonfuls) of Wentworth® Sodium Fluoride Rinse contains approximately 9 mg fluoride. One 16 fl. oz. bottle contains approximately 429 mg fluoride.


For caries — Adults and pediatric patients over age 6 years, 2 teaspoons (10 mL). Once a week, preferably at bedtime after thoroughly brushing the teeth, rinse vigorously around and between the teeth for one minute, then expectorate. DO NOT SWALLOW. For maximum benefit, do not eat, drink, or rinse mouth for at least 30 minutes afterwards.


Plastic bottle with child-resistant closure containing 16 fl. oz. (473 mL) (NDC 11527-735-16).


Store at Controlled Room Temperature, 68-77°F (20-25°C).
