Fluoride Treatment Aftercare: What to Do (and Avoid) for Healthy Teeth

Quick Navigation

Fluoride treatment is a simple and effective way to strengthen enamel and help protect teeth from decay. While the procedure itself takes only a few minutes, proper aftercare plays an important role in maximizing its benefits.

Here are practical guidelines on what to do — and what to avoid — after your fluoride treatment.

After fluoride coating

Patient should not rinse with water for 30 minutes. There is no danger if patient accidentally swallowed the fluoride coating.

If fluoride gel has been applied

• It is recommended to refrain from water and refrain from food for 30 minutes.

In case of enameling with fluoride varnish (In children with early tooth decay)

• Refrain from water and food for 1 hour after coating the fluoride varnish.

• Abstain from eating solid foods or foods that need to be chewed for at least 2 hours, but can eat soft foods and drink water.

• No brushing and flossing on the day of applying fluoride varnish both before bed and during the day. You can brush teeth normally the next day.

• If yellow stain is found on the teeth, don’t brush it off. The yellow stain will disappear by itself in 2-3 days.

• If irritation or allergies occur, rinse with clean water several times. If condition doesn’t improve, take the child to the dentist.

Following these simple recommendations will help fluoride work effectively and support long-term oral health. If you have any questions or concerns after your visit, our team at Bigmouthten Dental Clinic, Chiang Mai is always happy to assist.
