Dental Sealants – Types, Application, and Uses

Dental Sealants – Types, Application, and Uses

December 1, 2020

Dental sealants in Burlington, ON, refer to a thin plastic coating coated on the tooths chewing surfaces, mostly in the molars and premolars. Their primary purpose is usually to prevent tooth decay. Immediately after application, the sealants quickly bond with tooth the grooves and depressions on the teeth, thus protecting those teeth’ enamel.

Brushing and flossing can remove the food particles and plaque lodged on the teeth’ chewing surfaces, but the brush bristles won’t get deep into the nooks and crannies inside the back teeth. Therefore, sealants protect these susceptible areas of teeth from tooth cavities and decay by sealing plaque out.

Who Should Get Dental Sealants?

Molars and Premolars have the highest likelihood of developing cavities and decay. Dental sealants are, therefore, mostly addressed to children and teenagers. Dental sealants for adults are applied to adults who don’t have fillings or decay in the back teeth.

Dental sealants for kids are best applied to baby teeth as soon as they come out. This way, the baby molars and premolars are protected from the effects of tooth decay. The most affected age by decay are children of ages 6 – 14.

In other cases, Skyway Dental Care sealants can be applied to baby teeth that have started to develop deep grooves or depressions. Baby teeth play such an essential role in directing the baby’s correct tooth spacing at a young age. Therefore, it’s good to protect these teeth at an early age to avoid losing them prematurely.

Dental Sealant Procedure

The process of sealant application is a simple and painless one. It only takes a few minutes for your hygienist to cover each tooth with a sealant. Below is the process for the application of dental sealants.

  • First, the teeth on which the sealant material is to be applied is thoroughly cleaned to remove any dominant plaque and tartar.
  • The teeth are then carefully dried and coated using cotton to keep them as dry as possible.
  • To roughen them up, an acid solution is then laced on the chewing surfaces of the teeth being treated. This enhances the bonding of the sealant with teeth.
  • Next, the teeth are rinsed them dried
  • The last step is painting the sealant to the tooth enamel. It bonds directly to the tooth and later hardens. To speed up the hardening process, a special curing light is used on the sealant material.

How long do Sealants Last?

Sealants are meant to protect you from tooth decay for 10 years or more. However, they need to be checked for chipping and wearing that comes with constant use of back teeth. During the dental checkups, your sealants can be replaced if necessary.

What Materials are Used for Dental Sealants?

There are two types of sealants according to the material used. The two categories include:

  • Glass Ionomer
  • When applied, glass ionomer sealants take on an acid-base reaction when applied to the patient’s tooth. Glass Ionomer sealants also release fluoride, strengthening the tooth enamel for years. Dentist in Burlington applies sealants mostly on primary teeth.

    Pros: Their main advantage is the fact that they continually release fluoride, which minimizes the risk of tooth decay by more than 35%. The fluoride contains anti-bacterial properties that keep the teeth healthy and strong.

    Glass ionomer sealants can leak with time. However, the fluoride ions present in the sealants will protect teeth even after the leaks. Glass ionomer materials have superior aesthetics and always blend well with the color of natural teeth.

    Cons: Their main disadvantage is that they require more care than composite resin sealants. Glass ionomer provides more protection to teeth but has a lower retention rate.

  • Composite Resin
  • A curing light is used to apply composite resin sealants. They contain a plastic compound and ceramics, which blend with the color of teeth.

    Pros: Composite resin materials are strong and durable. They also have a higher retention rate compared to glass ionomers. Composite resins can last for 5 – 10 years. The composite resin material is also similar to your teeth color.

    Cons: Their only disadvantage is they don’t use an acid-base bonding reaction and do not release fluoride. When they eventually wear down, they do not effectively protect against cavities, as glass ionomers do.
