The sealing of dental fissures is a comparatively new direction in dentistry. It is a preventive measure that is supposed to protect the teeth against decay. Everybody knows that bacteria living in the food remnants on the surface of our teeth, is harmful to them. But why is teeth cleansing not enough?
To figure out whether fissure sealing is an option, let us first explain what they are. Fissures are the pits and relief on the surface of our teeth. They can have different shapes and depth; it is individual for each person. When the fissures are deep, saliva isn’t able to properly clean them, which leads to tooth decay.
The deeper the fissures are, the more food remnants gather inside them. Which means more material that will rot, producing more bacteria to ruin your teeth. Depending on the depth and shape of the fissures, they might require either invasive or non-invasive sealing. This procedure is especially important for children whose enamel is not strong enough and can easily be ruined by the decay.
The non-invasive method is just a filling of the fissure with a special sealant. It requires an overall healthy tooth and only works if the fissures has a simple shape. It is perfect for both the constant or freshly appeared primary teeth.
The invasive method is for the fissures whose shape is complicated or they are closed by chewing protrusions. In such cases, a pediatric dentist must widen it. It is performed without penetrating the dental enamel. The absence of tooth decay is also obligatory here.
The sealant can be either transparent or opaque. In the first case, it is convenient to watch the state of the fissure but impossible to determine the preservation of the sealant. With the opaque sealant, the situation is the opposite. All of them are enriched with fluorine to give teeth an additional protection.
When is it better to seal the fissures? Not later than half a year after dentition. This period is very important because the teeth must be protected before the fissures are filled with bacteria. So, the protection of your child’s teeth is your own responsibility and you are to decide, to seal or not to seal.
