The Benefits of Dental Sealants for Children

Over the last twenty years, awareness of the importance of applying dental sealants has increased. Yet many parents who did not undergo this procedure in their youth may need to educate themselves to gain a certain level of comfort before bringing in their own children for the procedure. A pediatric dentist or dental hygienist will be able to answer specific questions about sealants, but a basic understanding of their purpose and how they help to protect teeth will also help you to make an informed decision.

What Is a Dental Sealant?

A dental sealant is a protective barrier placed on children's teeth for the purpose of sealing out food and bacteria which result in cavities. Sealants used in conjunction with a comprehensive dental care routine that includes proper brushing, flossing, fluoride treatments and a healthy diet, will help maintain dental health. While brushing and flossing are critical components of any dental health regimen, sealants provide additional protection for the grooved areas of teeth from what is known as pit and fissure decay.

Which Teeth Should Be Sealed and When?

The number of teeth that should be sealed depends on your child's incidence towards dental caries. For maximum protection, dental sealants should be applied as soon as possible after permanent tooth eruption. This would be around age 6 for most children.

Who Applies Dental Sealants?

Sealants are placed during an office visit by a trained dental professional (dental hygienist, dentist). Prior to application, teeth should be properly cleaned and examined. The tooth is dried, a material is placed onto the tooth, then rinsed and dried off. Next, the sealant material is placed on the biting surface of the tooth and a special light is placed above the tooth to harden the sealant into the tooth surface. This procedure is usually is quick and painless; the child will need to stay still during the appointment.

  1. Tooth preparation – first, the dental hygienist will polish the surface of the tooth to remove plaque and food debris from the pit and fissure surfaces. Next the hygienist will isolate and dry the tooth. Then the hygienist will etch the surface of the tooth, rinse off the etching material and dry the tooth.

  2. Sealant application – the hygienist will apply the dental sealant material to the surface of the tooth with a brush; a self-curing light will be used for about 30 seconds to bond the sealant to the tooth surface.

  3. Evaluation – finally, the dental hygienist and dentist will evaluate the dental sealant and check its occlusion. Once the dental sealant has hardened it becomes a hard plastic coating, and you can chew on the tooth again.
