PreviDent OrthoDefense

INDICATIONS AND USAGE A dental caries preventive; for twice daily self-applied topical use. PreviDent® 5000 Ortho Defense™ 1.1% sodium fluoride toothpaste in a squeeze bottle is easily applied onto a toothbrush. This prescription toothpaste should be used twice daily in place of your regular toothpaste unless otherwise instructed by your dental professional. May be used in areas where 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. Adults and pediatric patients 6 years of age or older, apply a thin ribbon of PreviDent® 5000 Ortho Defense™ to a toothbrush. Brush teeth thoroughly twice daily for two minutes in place of your regular toothpaste. 2. After use, adults expectorate. For best results, do not eat, drink, or rinse for 30 minutes. Pediatric patients, age 6-16, expectorate 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 age 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 toothpaste which could cause dental fluorosis. Pediatric patients under age 12 should be supervised in the use of this product. Read directions carefully before using. Keep out of reach of infants and children.

ADVERSE REACTIONS Allergic reactions and other idiosyncrasies have been rarely reported.

Pregnancy 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 the litter size or fetal weight and did not increase the 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.
