Tooth enamel is the white portion of the tooth seen in your mouth. The enamel is the hardest substance in your body. It covers the “crown” of the tooth. Enamel acts as an insulator of your teeth. Hence, it protects the inner dentin from the external stimulus. The insulating properties of the enamel is due to it’s high mineral content. At 99% mineralization, enamel is considered a unique mineralised structure in your body. The highly crystallised structure of enamel makes it a strong structure. It is also this property of enamel that makes tooth whitening procedures possible.
When the calcium in enamel is replaced by fluoride, the surface of enamel becomes stronger. The new crystalline structure is then more resistant to decay. The acids of the bacteria cannot attack the tooth as easily. Therefore, brushing your teeth with a fluoridated paste or drinking water with optimised fluoride content or taking your child to your dentist for topical fluoride application plays a significant role on preventing tooth decay.
Wearing out of enamel causes tooth sensitivity. Faulty toothbrushing, consumption of highly acidic food, tooth decay are some of the reasons for loss of enamel.
