Due in large part to fluoride, tooth decay is far less prevalent then it was a generation ago. The American Dental Association (ADA) says fluoride reduces tooth cavities in adults and children. It also strengthens tooth structure and makes teeth more resilient to acid that is formed by bacteria.
Systemic fluorides are consumed through fluoridated water and in fluoride drops or tablets. Topical fluoride can be found in toothpaste, professional fluoride treatments and in mouth rinses. The ADA recommends the use of fluoride mouth rinses for anyone over age 6, since younger children may inadvertently swallow the rinse.
Dental fluoride rinses are meant to be rinsed and spit out. They can be purchased over-the-counter, or stronger varieties may be prescribed by your dentist. The ADA says as with all nutrients, fluoride is safe when used as directed. There are possible side effects linked to the use of dental fluoride rinses.
Sodium Fluoride Effects
Sodium fluoride rinse (including Listermint and PreviDent) strengthens tooth enamel and diminishes the effects of bacteria and acid on teeth. When used as directed, few side effects are connected to sodium fluoride rinses. Some people may experience black, tarry stools, diarrhea, bone or joint pain or vomiting.
Fluoride Topical Effects
Fluoride topical rinses (including ACT fluoride rinse, Oral-B Anti-Cavity and PerioMed) are often used by people who don't have access to adequate levels of fluoride topical in their drinking water. The side effects associated with fluoride topical are discolored teeth and a deterioration of tooth enamel. Other possible adverse reactions are weakness, headache and upset stomach.
Allergic Effects
Severe allergic responses to both sodium fluoride and fluoride topical rinses include swelling of the mouth, lips, tongue and/or face, hives, rash and itching. Additional reactions include tightness in the chest and breathing problems.
Contact your doctor right away if you experience any of these symptoms following the use of dental fluoride rinses. Also inform your doctor and dentist if you are on a low-salt or salt-free diet, since you may require special tests or may be advised against using fluoride topical rinses.
