When we look at our teeth ae are looking at the outermost layer of the tooth called enamel. This layer is the hardest substance in the human body (even harder than bones) and is made up purely of minerals.
The enamel layer acts as a shield and provides a first line of defense to the underlying layers of the tooth (dentin and nerves). The enamel layer is translucent and this layer gives the teeth their bright, white appearance.
Unfortunately, the enamel once damaged or lost due to decay, poor eating habits or poor oral hygiene cannot be brought back. Hence, it is crucial to try and keep the enamel layer as healthy as possible.
Fluoride varnish application is one of the best ways to strengthen the enamel layer and protect your teeth from decay. Fluoride acts by binding to the tooth minerals and forming an extremely hard substance called fluorapatite.
Fluoride varnish application is an extremely simple and effective process to protect your teeth. The varnish is simply applied to your teeth and is left the harden for some time and you’re done! There is no need for any dental anaesthesia for the application of this material.
Fluoride varnish application leads to strengthening of the tooth enamel making the teeth more resistant to decay. It reduces the need for any other forms of dental intervention like composite fillings and root canal procedures. This reduction in additional dental treatments and increased tooth protection makes fluoride varnish application cost effective.
The regimen of fluoride application as recommended by the American Dental Association is once every 6 months.
