FLUORIDE APPLICATION & FISSURE SEALANT
Fluoride application is when a dentist 'paints' a fluoride to strengthen teeth. This is usually applied on children and sometimes adults with a high risk of decay.
The fluoride ion comes from the element fluorine. Fluoride, either applied topically to erupted teeth, or ingested orally (called systemic fluoride) during tooth development, helps to prevent tooth decay, strengthen tooth enamel, and reduce the harmful effects of plaque. Fluoride also makes the entire tooth structure more resistant to decay and promotes remineralization, which aids in repairing early decay before the damage is even visible.
Sealants protect the chewing surfaces of teeth. This is done by painting dental resin on the teeth to make sure food and bacteria do not get stuck in the grooves of your back teeth. When the grooves ( called pits and fissures) are sealed, teeth are much less susceptible to cavities.
