If your youngster has the misfortune of a cavity, it probably is on the chewing surface of the back tooth. The AAPD reports 80 – 90% of cavities happen on the chewing surfaces of permanent teeth, whereby 44% happen on baby teeth. But this kind of cavity – occasionally referred to as pit and fissure decay – may be prevented in adolescents, children and adults with dental sealant placement.
How do Sealants Prevent Decay?
The grooves and depressions on kid’s back teeth assist them in chewing and grinding food. But, the deep crannies also can trap debris and food where it is hard to keep clean, which makes them prime areas for decay to begin. With dental sealants, the dentist applies a plastic, thin material to the molar’s chewing surfaces, permitting the enamel to become smooth, as well as protected from this bacteria source.
Sealants may last as many ten years, according to the NIDCR. Though, if the dental hygienist or dentist sees any worn areas or chips on your youngster’s sealants, she or he may repair them merely by adding more of the transparent material.
Which Teeth Ought to Be Sealed and When?
All permanent or baby teeth that have deep fissures or pits are at risk for decay, and are thereby candidates for dental sealants, according to the AAPD. Most dental professionals suggest sealing baby molars because those teeth play a vital part in holding space for your permanent teeth. Keeping those teeth cavity-free may prevent your youngster from losing them early on.
The National Institute of Dental and Craniofacial Research recommends that the right time to seal molars is as soon as they come in – before the molars have an opportunity to decay. The initial permanent molars erupt about six years of age, according to the ADA eruption chart, whereby the following teeth in line for dental sealants are 2nd molars, which typically erupt from 11 to 13 years of age. The dentist also may suggest sealing your youngster’s premolars if there’s any deep grooves. The premolars come in between the age of 10 to 11 and replace all baby molars.
Sealants and Wisdom Teeth
The final teeth to come in to your youngster’s mouth are the 3rd molars – called wisdom teeth – occasionally between age 17 to 21. Wisdom teeth often aren’t shaped like the additional molars and, in most cases, don’t have enough space to erupt correctly, as observed by the AAOMS.
As a matter of fact, 9 out of 10 folks have at least one wisdom tooth that is impacted. Many wisdom teeth therefore can be extracted while the individual still is a young adult, before they trigger problems and the roots are completely developed. It’s mainly why sealants aren’t suggested for wisdom teeth.
However, occasionally someone’s mouth is big enough to accommodate all 4 wisdom teeth in their correct position. In that case, if the dental professional feels that these teeth are going to be a functional part of your youngster’s dentition, dental sealants might be an excellent choice to prevent them from decaying.
