Introducing Dental Sealants


Dental sealants are the coverings for damaged or broken teeth. They seal the surface of the teeth and ensure that the teeth are safe from decay and cavities in the long run. Placing a layer between the teeth's biting surfaces and bacteria and food helps keep them free of cavities. Here is a brief guideline about everything you need to know before getting the sealants.

Procedure for getting sealants:

  1. The tests taken before getting the sealants include a detailed examination of the teeth. Teeth X-rays should be taken from different angles to know the exact position and condition of the teeth. You must thoroughly clean your teeth with a toothbrush before going to the dentist, as it will remove all the junk trapped between the teeth that can lead to complications.
  2. The dentist positions your chin in an elevated manner to smoothly do the procedure. After opening the mouth and getting in a perfect position, the dentist covers all the surrounding teeth except those that require sealant application. They use cotton rolls to protect the rest of the teeth and separate them from the affected tooth.
  3. Now is when acidic etchant is applied to make the surface rough. The etching material can be in liquid or gel form. The etchant should come in contact with the soft tissues and skin. It needs to stay on each tooth for about15 20 seconds.
  4. After 15 to 20 seconds, they rinse off the material thoroughly and dry the mouth using a dried high-volume mouth vacuum. The tooth's surface will appear chalky once the saliva is dried out; re-etch the teeth if it doesn't have a frosty appearance.
  5. The surface is filled with the sealant material, which flows from one end to the other. It should not entrap any air. The final step is to let it heal and cure.

How long do dental sealants last?

Dental sealants last for 10 to 12 years on average. Sometimes they get damaged because the chewing surface comes in contact with the food and goes through the wearing and tearing process many times a day. To ensure that they are safe and remain undamaged, you need to go for regular checkups so that if there is any damage, it can be repaired earlier. If the dental sealants receive proper care, they can last longer than the expected time.

How much do they cost?

The cost of the sealants varies from country to country. It also depends upon the quality of the material used for making the sealants. On average, the cost of dental sealants for one tooth is almost 40$ to 60$. But looking at the perks they provide for having them for a very long time makes them cost-efficient and worth it.


Going for dental sealants in case of crooked or damaged teeth to enjoy the food properly makes more sense for making your teeth healthy, but the process is very budget-friendly. Taking proper care makes them cost-efficient and reliable.
