Dental sealant is a thin-layered plastic coating, which is painted on the chewing surfaces of teeth (usually the back teeth- the premolars and molars) to prevent tooth decay. This lasts for many years. The sealant gets bonded into the depressions and grooves of the teeth very quickly, forming a protective shield over the enamel. This blocks out germs and food. Once applied, sealants protect against 80% of cavities for two years and continue to protect against 50% of holes for up to 4 years. Studies say children aged 6 to 11 years without sealants have almost three times more first molar cavities than children with sealants.
The hard enamel coating which protects the teeth gets changed as it ages to become stronger. Fluoride, which we can get in toothpaste and some drinking water or treatments available at the dental office — can strengthen enamel. But, sometimes, it’s hard to get fluoride into those pits and fissures regularly. Fortunately, there is an excellent solution to this problem: dental sealants. Sealants are generally placed in liquid form on the tooth and then cured either with light activation or chemically. Before the process begins, the tooth surface is first treated with an acid etch to enhance the wetting of the tooth. This is done with the liquid sealant and to optimize the mechanical retention of the sealant. Sealants must also be of low enough viscosity to flow readily into the pits and fissures on the tooth surface and to wet the tooth adequately. According to state law and regulations, sealants can be applied by a dentist, dental hygienist, or another qualified dental professional. This procedure is usually done in dental offices or using portable dental equipment in community settings like a school. A sealed tooth is less prone to the cavity, need more expensive dental treatment later on, or, most importantly, cause your dental pain.
A cavity is mostly developed on the chewing surfaces of the back teeth, as these layers are not smooth, unlike other areas of your teeth. Instead, they are consist of tiny grooves referred to as “pits and fissures,” catch bacteria and food particles. And the bristles on a toothbrush can’t always reach all the way to clean. This stimulates the perfect condition for tooth decay.
The Procedure Of Dental Sealant Placement
As because tooth enamel does not carry any nerves, putting a sealant is painless and does not routinely need numbing shots. At first, the tooth or teeth to be sealed are tested, and if minimal decay is found, it will be easily removed. The tooth will then be properly cleaned and dried. Then a solution that will little roughen or “etch” the surface is applied to make the sealing material fixed better. The tooth is then washed thoroughly and dried again. The sealant is then placed on the tooth in liquid form and becomes hard in about a minute with the help of a curing light.

Sealed teeth need the same conscientious dental hygiene as unsealed teeth. It would help if you continued to brush
