Fluoride Application by gels/foam is a highly concentrated form of fluoride which is applied to the tooth's surface, by a dentist, dental hygienist or other health care professional, as a type of topical fluoride therapy. It is not a permanent treatment but due to its adherent nature, it is able to stay in contact with the tooth surface for several hours. It may be applied to the enamel, dentin or cementum of the tooth and can be used to help prevent decay, remineralize the tooth surface and to treat dentin hypersensitivity.

• Fluoride varnishes are available in different flavors which can be advantageous when treating younger patients.
• Fluoride trays filled with fluoride foam.
• They are easily and quickly applied.
• Due to the small amounts used and the rapid setting time, there is only a small or negligible amount of fluoride ingested.
• Application requires very little equipment and so it can be applied in settings where a dental operatory is not available.
• It has a sticky consistency which helps it to adhere to the tooth's surface thereby allowing the fluoride to stay in contact with the tooth.
• Based on published findings, professionally applied fluoride varnish does not appear to be a risk factor for dental fluorosis, even in children under the age of 6. This is due to the reduction in the amount of fluoride which may potentially be swallowed during the fluoride treatment because of the small quantities used and the adherence of the varnish to the teeth.

According to the published findings, professionally applied fluoride varnish does not appear to be a risk factor for dental fluorosis, even in children under the age of six. This is because of the reduction in the amount of fluoride which may also be swallowed during the fluoride treatment. The small quantities of dental fluorides used and the adherence of the varnish to the teeth are of great benefit for the individuals with the probability of dental caries. So, it is necessary to take proper care from time to time to avoid such cases of dental fluorosis in the sooner or later years.

Nowadays, there are different types of fluoride application methods which are now utilized successfully based on the dental status of the patients. You can choose from the available methods and get the best fluoride application done for yourself.
