A Deep Dive into Dental Sealants

  • What Are They?

    Dental sealants are protective barriers applied to the chewing surfaces of back teeth. Their job is simple: fend off tooth decay. But behind this simple job is a world of science and precision. Ain't it just the bee's knees?

  • Dental sealants is another safety net that can be used to protect your teeth from tooth decay and cavities. It is a thin plastic coating that are placed on the chewing surface of the back of the teeth to help protect them from decay. these quick and easy, tooth - coloured plastic resin coatings will fill those little groves forming a protective shield over the tooth's enamel so that bacteria have nowhere to hide. 
  • Dental sealants are placed on the chewing surfaces of the molars and premolars because they have grooves that make them vulnerable to decay. These grooves and fissures can be hard to clean with a normal toothbrush. Plaque accumulates in these areas attacking the enamel causing cavities to develop.
  • Why Bother?

    Ever heard the saying, "An ounce of prevention is worth a pound of cure?" Dental sealants are the embodiment of this idiom. They can save you not only from cavities but also from the dreaded drilling. And who wouldn't want that?

  • Due to the high probability of developing cavities in the back teeth, teenagers and children are ideal candidates for dental sealants.

    However, sealants can also benefit adults without fillings or decay.

    Typically, you should take your child to get sealants as soon as the permanent premolars and molars come in. By doing this, you protect their teeth from the cavity-prone years

The Procedure: Step by Step

  1. Preparation

    Before anything else, the tooth is cleaned. Any lingering bits of lunch or morning coffee are bid adieu.

  2. Application

    The tooth is then dried and a liquid sealant solution is applied. Don't panic! This just roughens the surface, allowing the sealant to stick better.

  3. Sealant Placement

    The tooth is dried once again and the sealant is painted on. It's as artistic as it sounds but with a focus on precision.

  4. Hardening

    Using a special light, the sealant is hardened and voila! You've got yourself a sealed tooth. Pretty nifty, right?
