Learn about Sealants, what are they, how they help, what to consider when choosing sealants.

Sealant use in preventing Dental Caries

Has your dentist talked to you about using sealant in your child’s teeth? Sealants are used, as the name suggests, to seal-off the groves of the teeth and make them “flat”. These sealants make the tooth “flat” and food is less likely to get caught in the groves and cause caries. The effectiveness of sealants in preventing caries is believed to be as high as 51% compared to no sealant1.  Normal wear and tear of biting forces can cause sealants to lose effectiveness over time. However, a study showed effectiveness lasted nearly 9 years2. Sealants are not for everyone, for example if your child’s teeth are naturally flat, have fewer grooves or flat due to child grinding the teeth, your dentist may not recommend sealant. Your child’s dentist is the best judge of your child’s need for a sealant.  

Are all Sealants equal?

Not all sealants are created equal, some sealants are believed to contain a chemical called BPA. This BPA can leach from sealant into the saliva3 and can cause issues in children. The levels are not believed to be significant, however use of BPA free sealants is becoming more common. Sealants and other measures can help prevent or arrest caries, talk to your dentist today. As the old adage goes “an ounce of prevention is worth a pound of cure”.
