Dentists and doctors all over the world use fluoride varnish to help prevent, slow down, or stop tooth decay from progressing further. Fluoride varnish treatments can best help prevent decay if the patient is also brushing with a fluoride toothpaste, flossing, getting regular dental care, and eating a healthy diet.
Fluoride varnish is painted on the top and sides of each tooth with a small brush. It microscopically soaks into the tooth throughout the day, but can last for several weeks to several months. Although it initially feels sticky when it is first applied, it will eventually dissolve as you go about your day. It can be brushed off 4 to 12 hours after application. Fluoride is an excellent preventative care service.
Daily use of fluoride in our water and toothpaste is normal and not harmful to your body. In recent years, the CDC has lowered the amount of fluoride in the drinking water because it has become pervasive in our society such as in foods, chewing gums, and toothpaste. Fluoride is still a viable adjunct to preventing tooth decay and the majority of developed countries continue to use it.
