Dental sealants are one of the most effective methods of preventing tooth decay in children. Although it sounds complicated, it is a simple and painless procedure that involves applying a thin layer of a protective substance to the chewing surface of the teeth, most often the molars. The purpose of sealants is to protect hard-to-reach grooves and pits from the accumulation of bacteria and food debris that can lead to tooth decay. In the following essay, we explain exactly what dental sealants are, when they are performed, and why they are so important for the oral health of children.
What is sealing?
Sealing is a preventive procedure that is performed mainly on children's permanent teeth - usually molars (so-called sixths), which appear around the age of 6. Sometimes baby teeth are also sealed if they have deep grooves, and the child is at increased risk of tooth decay.
The procedure consists of the following steps:
- cleaning the tooth of deposits and plaque,
- drying the tooth and preparing it with a special enamel etching agent,
- applying a sealant - a thin layer of resin-based material,
- hardening the material using UV light.
The whole procedure takes only a few minutes for each tooth, is completely painless and non-invasive - it does not require drilling or anesthesia.
Why is sealing important?
Children often have difficulty brushing their teeth thoroughly, especially those at the back of the mouth. The grooves on the surface of the molars are deep and narrow, which allows food debris and bacteria to accumulate. Cavities most often develop in these places.
Sealing protects the tooth from contact with acids and bacteria, prevents plaque from building up, reduces the risk of caries by up to 80% in molars, and supports the maintenance of healthy teeth for many years. In addition, using sealants can help parents and children save time, stress, and costs associated with treating cavities
When is the best time to have a tooth sealed?
The best time to seal a tooth is right after it has erupted, before decay appears on it. In children, these are usually:
- sixth permanent teeth (first molars) - they grow around the age of 6,
- seventh permanent teeth (second molars) - around the age of 12,
- sometimes premolars - depending on the structure of the tooth and the dentist's recommendations.
Sealing is usually done only once, but regular check-ups are important because the sealant can wear off or chip over time. Then the dentist can fill in the missing material.
Is sealing safe?
Yes - sealing is considered a completely safe procedure. The materials used for sealing have been tested and approved by medical institutions. The risk of complications, allergic reactions, or undesirable side effects is minimal.
Parents may have concerns about the presence of bisphenol A (BPA) in sealants, but the amounts of any trace residues of this substance are negligible and do not pose a threat to the child's health, especially when compared to the risk of tooth decay and the need for tooth drilling.
In Conclusion
Tooth sealants for children are a simple, safe, and very effective way to prevent cavities. They protect the most vulnerable tooth surfaces, make daily hygiene easier, and reduce the need for future treatment. It is worth remembering that although sealants significantly reduce the risk of cavities, they do not replace daily brushing, flossing, and a healthy diet. Regular visits to the dentist, good hygiene, and preventive treatments such as sealants are key to a healthy smile for your child throughout their life.
