Fluoride varnish is a dental treatment that can help prevent tooth decay, slow it down, or stop it from getting worse. Fluoride varnish is made with fluoride, a mineral that can strengthen tooth enamel (outer coating on teeth).
Keep in mind that fluoride varnish treatments cannot completely prevent cavities. Fluoride varnish treatments can best help prevent decay when a child is also brushing using the right amount of toothpaste with fluoride, flossing regularly, getting regular dental care, and eating a healthy diet.
Is Fluoride Varnish Safe?
Fluoride varnish is safe and used by dentists and doctors all over the world to help prevent tooth decay in children. Only a small amount is used, and hardly any fluoride is swallowed. It is quickly applied and hardens. Then it is brushed off after 4 to 12 hours.
Some brands of fluoride varnish make teeth look yellow. Other brands make teeth look dull. However, the color of your child's teeth will return to normal after the fluoride varnish is brushed off. Most children like the taste.
How is Fluoride Varnish Put on the Teeth?
Fluoride varnish is painted on the top and sides of each tooth with a small brush. It is sticky but hardens once it comes in contact with saliva. Your child may feel the hardened varnish with his tongue but will not be able to lick the varnish off.
It does not hurt when the varnish is applied. However, young children may still cry before or during the procedure. Fortunately, brushing on the varnish takes only a few minutes. Also, applying the varnish may be easier when a child is crying because his mouth will be slightly open.
You may be asked to hold your child in your lap while you are placed knee-to-knee with the person applying the varnish.
