Sealants greatly aid in the prevention of cavities, especially among the young ones. Recent studies show that about 4 million preschoolers suffer from tooth decay. Experts state that cavities in these children are often due to food particles being trapped in hard to clean spots in the mouth, particularly the grooves and depressions on the chewing surfaces of the back teeth. When the food particle reacts with bacteria, acid forms and in turn breaks down tooth enamel. This process leads to the formation of cavities.
How do sealants help in preventing cavities? These clear or tooth colored sealants, typically made of plastic, prevent bacteria and food particles from residing in these susceptible areas like the pits and grooves on the chewing surfaces of back teeth.
Where and how are sealants applied? For children, they are applied on permanent back teeth. In terms of their application, to seal the pits and grooves, they are painted onto the teeth surface.How long do they last? It is important to note that sealants go through the natural wear and get damaged over time; therefore, they are not permanent. Typically, they last for five years or more depending on the material used. Regardless of this fact, they are still wise investments as getting them is less expensive than having decays treated.
Do sealants prevent oral diseases or problems in general? No, they don’t. Having sealants is not equal to not suffering from decays or other dental diseases. Fact is, sealants do not prevent the onset of gum diseases and decay between teeth. This is why it is still imperative to take your child to regular dental check-ups.
