Uses
A dental caries preventive, for once daily self-applied topical use. It is well established that 1.1% sodium fluoride is safe and extraordinarily effective as a caries preventive when applied frequently with mouthpiece applicators. 1-4 SF 1.1% Brush-On Gel in a squeeze-tube is easily applied onto a toothbrush as well as a mouthpiece tray. This prescription dental gel should be used once daily following use of a regular toothpaste unless otherwise instructed by your dental professional. May be used whether or not drinking water is fluoridated since topical fluoride cannot produce fluorosis. (See WARNINGS for exception.)
Dosage and administration
Follow these instructions unless otherwise instructed by your dental professional: 1. After brushing thoroughly with toothpaste, rinse as usual. Adults and pediatric patients 6 years of age or older, apply a thin ribbon of gel to the teeth with a toothbrush or mouth trays once daily for at least one minute, preferably at bedtime. 2. After use, adults expectorate gel. For the best results, do not eat, drink, or rinse for 30 minutes. Pediatric patients, age 6-16, expectorate gel after use and rinse mouth thoroughly.
Contraindications
Do not use in pediatric patients under age 6 years unless recommended by a dentist or physician.
Warnings
Prolonged daily ingestion may result in various degrees of dental fluorosis in pediatric patients under 6 years, especially if the water fluoridation exceeds 0.6 ppm, since younger pediatric patients frequently cannot perform the brushing process without significant swallowing. Use in pediatric patients under age 6 years requires special supervision to prevent repeated swallowing of gel which could cause dental fluorosis. Read directions carefully before using. If using a mouthpiece application, prolonged exposure (longer than 1 minute) may result in oral irritation, such as burning. KEEP THIS PRODUCT OUT OF THE REACH OF CHILDREN. IN CASE OF ACCIDENTAL OVERDOSAGE, SEEK PROFESSIONAL ASSISTANCE OR CONTACT A POISON CONTROL CENTER IMMEDIATELY.
Precautions
Not for systemic treatment. DO NOT SWALLOW.
Side effects (adverse reactions)
Allergic reactions and other idiosyncrasies have been rarely reported.
Pregnancy
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 the litter size or fetal weight and did not increase the frequency of skeletal or visceral malformations. Epidemiological studies conducted in areas with high levels of naturally fluoridated water showed no increase in birth defects. Heavy exposure to fluoride in utero development may result in skeletal fluorosis which becomes evident in childhood.
Breastfeeding
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 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.
Use in children
The use of SF 1.1% Brush-On Gel in pediatric age groups 6 to 16 years as a caries preventive is supported by pioneering clinical studies with 1.1% sodium fluoride gels in mouth trays in students age 11-14 years conducted by Englander, et al. 2,3,4. Safety and effectiveness in pediatric patients below the age of 6 years have not been established. Please refer to the CONTRAINDICATIONS and WARNINGS sections.
Overdose
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 and 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) have 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) have been ingested, induce emesis, 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 (a thin ribbon) of SF 1.1% Brush-On Gel contains 2 mg flouride. A 2 oz. tube contains 266 mg fluoride.
