One question worth asking
Is fluoride covered at my age on this plan, or is it an out-of-pocket line?
Custom fluoride tray
D5986. A custom-made tray for applying fluoride gel at home, usually after radiation treatment.
Fluoride is painted or brushed onto teeth to strengthen enamel and slow early decay. Silver diamine fluoride is a stronger liquid that can stop a small cavity from growing without drilling.
The teeth are dried and the varnish is painted on in a minute or two; it sets on contact with saliva and keeps working for months. Silver diamine fluoride is a different liquid that can stop a small cavity from growing without drilling, though it stains the treated spot dark. Codes differ by which product is used and whether it is counted per visit, per tooth or per arch. Most plans file this as Preventive. What they actually pay varies by plan.
