Flouride
Applications

Fluoride Applocation 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, dentine or cementum of the tooth and can be used to help prevent decay, remineralise the tooth surface and to treat dentine hypersensitivity

Fluoride varnishes are available in different flavours 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.
