Dental sealants are a highly effective way to protect your teeth from decay. As a preventive measure, they are often applied to the chewing surfaces of molars and premolars to form a protective barrier against harmful bacteria and food particles. If you’re wondering what are dental sealants in dentistry and how they can help, read on to discover the benefits, the application process, and who can benefit from them.
Understanding dental sealants
What are sealants in dentistry?
They are thin, plastic coatings that are applied to the chewing surfaces of the back teeth (molars and premolars). The purpose of these coatings is to act as a physical barrier, preventing the buildup of plaque, food particles, and bacteria that can cause tooth decay. Sealants are typically applied to areas that are difficult to clean with regular brushing.
How dental sealants work
The sealant material bonds to the tooth’s enamel and fills in the grooves and fissures of the teeth, which are often deep and hard to reach with a toothbrush. By sealing these crevices, dental sealants provide a smooth surface that is easier to keep clean, preventing cavities and decay.
What is teeth sealant made of?
It is primarily composed of resin-based materials, which are durable and designed to bond securely to tooth surfaces. They come in two main types: light-cured and chemically-cured. Both types offer similar protection but are applied in different ways. Most modern sealants are clear or tooth-colored, ensuring they blend naturally with your teeth. Benefits of dental sealants
Prevention of tooth decay
If you are wondering what are sealants for teeth benefits, you must know their most significant benefit of dental sealants is their ability to prevent tooth decay. By covering the grooves in the back teeth, sealants prevent the accumulation of plaque and bacteria that lead to cavities. This preventive measure can be especially effective for children and teens who are more prone to tooth decay.
Cost-effectiveness compared to fillings
Compared to dental fillings, sealants are relatively inexpensive. Since they are a preventive measure, they can save you money by avoiding the need for fillings and other more extensive treatments later on. The cost of sealant application is a fraction of the cost of filling cavities, making it a highly cost-effective option.
Long-term oral health benefits
Dental sealants provide long-term protection, as they shield teeth from the factors that lead to cavities. Over time, this protection helps maintain the overall health of your teeth, reducing the need for invasive treatments and contributing to better oral hygiene habits. Regular dental visits ensure that sealants are maintained and re-applied when necessary.
Who should get dental sealants?
Ideal candidates: children vs. adults
Dental sealants are most commonly applied to children and teenagers, as their permanent molars are particularly vulnerable to decay. However, adults who are prone to cavities can also benefit from sealants, especially if they have deep grooves in their teeth. Sealants provide a protective layer that reduces the risk of developing cavities in those areas.
Recommendations by age group
The American Dental Association recommends that children get dental sealants as soon as their permanent molars come in, typically around age 6. The sealants can be applied to the second molars around age 12. While sealants are more common in younger patients, adults without existing dental work in their molars can also consider them to prevent future decay.
Special considerations for high-risk individuals
People with higher risks of tooth decay, such as those with poor oral hygiene habits, high sugar consumption, or a history of frequent cavities, may benefit from dental sealants as an extra layer of protection. Your dentist will assess your risk and advise on whether sealants are a suitable option.
Application process of dental sealants
Step-by-step procedure
Once you know exactly what is a sealant on a tooth, the process of applying them is simple and typically completed in one visit. Here’s a step-by-step guide:
- Cleaning the tooth: Your dentist will begin by thoroughly cleaning the tooth or teeth to remove any plaque or food particles.
- Drying the tooth: The tooth is then dried and isolated to prevent moisture from affecting the sealant application.
- Applying the sealant: The liquid sealant is applied to the grooves of the tooth and allowed to bond with the enamel.
- Curing the sealant: Depending on what are sealants for teeth made of, they are either cured with a special light or chemically hardened.
- Final adjustments: The dentist will ensure the sealant is properly bonded and adjust any excess material to ensure a smooth surface.
Time required for application
The entire process usually takes about 20 to 30 minutes per tooth. Since it’s a non-invasive procedure, it’s quick and can be completed in a single dental visit.
Pain and discomfort levels
The procedure is pain-free, with no needles or drilling involved. Some patients might experience mild sensitivity after the application, but this typically subsides quickly. In general, most people find the process comfortable and easy.
Effectiveness and longevity of dental sealants
Duration of protection offered
Dental sealants provide effective protection for up to 10 years, depending on wear and tear. However, their longevity depends on the patient’s oral hygiene and whether they engage in activities that could damage the sealant (like chewing ice or hard candy). Regular dental checkups ensure that sealants are intact and functioning properly.
Factors affecting longevity
Several factors can impact how long dental sealants last, including:
- Oral hygiene: Proper brushing and flossing help maintain sealant integrity.
- Dietary habits: Avoiding sticky or hard foods can prevent sealant damage.
- Wear and tear: Activities like teeth grinding or clenching may reduce the lifespan of the sealants.
Maintenance and follow-up care
To ensure that your dental sealants continue to protect your teeth, regular dental visits are essential. Your dentist will check for any signs of wear or damage during your routine checkups. If necessary, they will reapply or repair the sealants.
Dental sealants are an effective preventive measure to protect your teeth from decay, offering both immediate and long-term benefits. Whether for children or adults, this simple and affordable treatment can significantly reduce the risk of cavities and improve overall oral health.
