Dental Health and Fluoride Treatment
When Is Fluoride Intake Most Critical? continued...
In addition, people with certain conditions may be at increased risk of tooth decay and would therefore benefit from additional fluoride treatment. They include people with:
- Dry mouth conditions: Also called xerostomia, dry mouth caused by diseases such as Sjögren's syndrome, certain medications (such as allergy medications, antihistamines, antianxiety drugs, and high blood pressure drugs), and head and neck radiation treatment makes someone more prone to tooth decay. The lack of saliva makes it harder for food particles to be washed away and acids to be neutralized.
- Gum disease: Gum disease, also called gingivitis, can expose more of your tooth and tooth roots to bacteria increasing the chance of tooth decay.
- History of frequent cavities: If you have one cavity every year or every other year, you might benefit from additional fluoride.
- Presence of crowns and/or bridges or braces: These treatments can put teeth at risk for decay at the point where the crown meets the underlying tooth structure or around the brackets of orthodontic appliances.
Ask your dentist if you could benefit from additional fluoride.
Are There Risks Associated With Fluoride Use?
Fluoride is safe and effective when used as directed but can be hazardous at high doses (the "toxic" dosage level varies based on an individual's weight). For this reason, it's important for parents to carefully supervise their children's use of fluoride-containing products and to keep fluoride products out of reach of children, especially children under the age of 6.
In addition, excess fluoride can cause defects in the tooth's enamel that range from barely noticeable white specks or streaks to cosmetically objectionable brown discoloration. These defects are known as fluorosis and occur when the teeth are forming -- usually in children younger than 6 years. Fluorosis, when it occurs, is usually associated with naturally occurring fluoride, such as that found in well water. If you use well water and are uncertain about the mineral (especially fluoride) content, a water sample should be tested. Although tooth staining from fluorosis cannot be removed with normal hygiene, your dentist may be able to lighten or remove these stains with professional-strength abrasives or bleaches.
