Fluoride is a naturally occurring mineral that helps prevent tooth decay and build strong teeth. Enamel is the outer surface of teeth which can be weakened by plaque bacteria attack, a process called demineralization. Minerals like fluoride, calcium and phosphate are deposited to the enamel layer from the food and waters we consume, a process called remineralization. Tooth decay occurs when demineralization exceeds the remineralization process. Hence the addition of fluoride in toothpaste, water supply and or fluoride treatment at the dentist can quicken the remineralization process and prevent tooth decay.
Fissure sealants is a preventive dental treatment that is common in children’s and adult dentistry. It is also known as pit and fissure sealants and as the name suggests there are hard protective coatings that cover and protect teeth with deep, narrow grooves that are at a high risk of developing decay. The deep grooves are hard to reach with toothbrush bristles hence allowing collection of food and plaque. By creating a smooth surface that is more easily cleaned, fissure sealants can significantly reduce the risk of decay and the need for fillings in the future.
