Fluoride treatment and insurance
Why fluoride is usually preventive, the age limits many plans put on it, and what to tell an adult patient whose plan won't pay.
The National Association of Dental Plans lists fluoride treatment in the diagnostic and preventive group, which is usually paid without a deductible. Whether it is paid for a given patient often depends on age.
Typical limits
- An age limit. Many plans pay fluoride for children only, up to an age the plan sets. Some plans pay it for adults too, often only when there is a higher risk of decay.
- A frequency limit, often tied to the cleaning schedule.
Before the visit
- Look for fluoride under limitations, with its age and frequency rules.
- For an adult, check whether fluoride is covered at all before applying it.
- If it isn't covered, tell the patient the fee and let them decide.
This is how plans usually work, not how every plan works. The patient's own plan documents and the insurer decide what's paid.
