One of the most common dental problems in the world is cavities. The bacterial buildup between your teeth causes it. This buildup is often a result of poor oral hygiene or leftover food particles between your teeth. When your teeth are exposed to bacteria and plaque, cavities will start to form. Although there are different procedures, like dental fillings to remove cavities from your teeth, one of the most effective treatments is dental sealants.

In this blog, we will learn how dental sealants work against cavities and keep your teeth healthy. So, let’s begin!

What Are Dental Sealants?

Dental sealants are a protective layer of plastic coating that is applied to the surface of your teeth. They are meant to fill the gaps and pits where your food leftover and bacteria is trapped. It is a non-invasive and effective procedure that can protect your teeth for years to come.

Who Should Get Dental Sealants?

Dental sealants should be applied to the following individuals:

  • Children: Their permanent teeth are most vulnerable to cavities.
  • Adults: An individual with an existing cavity or a filling in their teeth can benefit from sealants.
  • People with Deep Grooves: Individuals with deep pits and grooves are at a high risk of developing cavities.

How Sealants Protect Your Teeth from Cavities?

Here is how dental sealants protect your teeth from cavities:

Physical Barrier:

A sealant creates a shield around your teeth. This shield will prevent food and bacteria from entering the pits and grooves of your teeth.

Sealing Out Bacteria:

When the surface of your teeth is sealed properly, microorganisms like bacteria and debris cannot enter the pits. The protective layer will prevent them from reaching the surface and breaking the enamel.

Easier Cleaning:

The sealant makes the surface of your teeth smooth. This makes brushing easier and also reduces the risk of plaque and bacterial buildup.

How Are Sealants Applied?

A dental sealant is applied by following these steps:

1. Cleaning – A dental expert will clean and dry your teeth thoroughly.
2. Preparation – Once your teeth are dry, a conditioning gel is applied.
3. Rinsing and Drying – The conditioning gel is then rinsed off, and your teeth are dried again.
4. Application – A plastic sealant is applied to the surface of your teeth.
5. Hardening – With the help of a special blue light, the sealant is hardened.
