The Sealant is a resin-based material that is applied as a thin coating onto the pits and Fissures of the tooth’s chewing surface. This coating forms a protective barrier, preventing food particles, bacteria, and plaque from accumulating in these vulnerable areas and reducing the risk of tooth decay.
So, how are Fissure Sealants typically applied in dental practice:
Cleaning and Preparation:
- The tooth to be sealed is thoroughly cleaned using a dental handpiece, dental instruments, and a mild etching solution. This removes any debris, plaque, or remnants of food particles.
Isolation:
- The tooth is isolated and kept dry to ensure optimal Sealant adhesion. This is often done using cotton rolls, a dental dam, or other isolation methods.
Etching:
- An acidic etching gel is applied to the tooth’s chewing surface to create a rough surface. This roughness enhances the bond between the tooth and the Sealant.
Rinsing and Drying:
- The etching gel is then rinsed off, and the tooth is dried thoroughly to remove any excess moisture.
Application of Sealant:
- The Fissure Sealant material, usually a liquid resin, is applied directly onto the pits and Fissures of the tooth. The Sealant flows into the grooves and forms a protective coating.
Curing:
- A curing light is used to harden and set the Sealant. The light activates a chemical reaction, transforming the liquid resin into a solid, durable seal.
Fissure Sealants are a preventive measure in dental care, helping to protect teeth from cavities and decay by providing a physical barrier against harmful bacteria and acids—a great preventative solution.
The longevity of a Fissure Sealant can vary based on several factors, including the material used, oral hygiene practices, diet, and overall oral health. So, if you want them to last longer, make sure that you have a good Dental Hygienist. Fissure Sealants can last anywhere from several years to over a decade. Here are some general estimates for the lifespan of Fissure Sealants:
- Several Years (2-5 years): Many Fissure Sealants can last for a few years, providing effective protection during this period. However, regular dental check-ups are essential to monitor the condition of the Sealant and determine if reapplication is necessary.
- Mid-Term (5-10 years): Some Fissure Sealants can last up to a decade with proper oral hygiene and regular dental care. Good brushing and flossing habits and routine dental check-ups can help maintain the Sealant’s integrity and extend its lifespan.
- Long-Term (10+ years): In some cases, Fissure Sealants can last longer than a decade, especially if applied correctly and the patient maintains excellent oral hygiene. However, over time, the Sealant may wear down or chip.
Notably, Fissure Sealants are not permanent and may need to be reapplied or repaired over time.
Fissure Sealants can be used for both children and adults to help prevent tooth decay and cavities. Fissure Sealants are a preventive dental treatment that is often recommended, especially for children, as their newly erupted permanent molars and premolars are most susceptible to tooth decay.
- Children: Fissure Sealants are commonly applied to children’s permanent molars and premolars as soon as these teeth erupt. Typically, the first permanent molars erupt around age 6, and the second molars come in around age 12. Applying Sealants to these teeth helps protect them during the cavity-prone early years of their eruption.
- Adults: Fissure Sealants can also be used for adults, especially if deep grooves and Fissures on their molars and premolars are at risk for decay. Many adults have these deep grooves, making them susceptible to food and plaque accumulation, even with good oral hygiene. Sealants can be applied to provide an additional layer of protection against decay.
I’ve always loved Fissure Sealants a nice introduction to dentistry and part of preventive dentistry.
