Dental sealants are thin, protective coatings applied to the chewing surfaces of teeth, primarily the back molars and premolars. They function as a barrier, shielding the tooth enamel from food particles and cavity-causing bacteria. While commonly associated with children’s dentistry, adults can also significantly benefit from dental sealants to protect their teeth from decay.
Why Adults Should Consider Dental Sealants
Adults can find dental sealants advantageous because their teeth, like those of children, possess deep grooves and pits on the chewing surfaces where food debris and bacteria can easily accumulate. These areas are challenging to clean effectively with routine brushing and flossing, making them susceptible to decay. Sealants act as a protective shield, covering these vulnerable depressions and preventing the formation of cavities.
An adult might consider sealants if they have newly erupted permanent teeth without fillings, or if their existing teeth have deep fissures that are prone to trapping food. Individuals with a history of tooth decay, or those at high risk due to factors like dry mouth, certain medical conditions, or a diet high in sugar, can especially benefit. Sealants are a proactive approach to oral health, helping to avoid more extensive and costly treatments. They offer an additional layer of defense that complements regular brushing and flossing, rather than replacing these habits.
The Sealant Application Process
Applying dental sealants is a simple, non-invasive procedure that typically takes only a few minutes per tooth during a standard dental visit. The process begins with a thorough cleaning of the tooth surface to remove any plaque or food debris. After cleaning, the tooth is completely dried.
Next, a mild acid solution is applied to the chewing surface for a short period, which gently etches the enamel. This etching creates microscopic pores, allowing the sealant material to bond more effectively to the tooth. The tooth is then rinsed and dried again. Finally, the liquid sealant material is painted onto the grooves and pits of the tooth, where it flows into the etched areas. A special curing light is often used to harden and set the sealant in a matter of seconds, creating a durable protective layer.
How Long Dental Sealants Last
Dental sealants offer long-lasting protection, typically remaining effective for several years. On average, sealants can protect teeth from decay for approximately five to ten years, with some lasting even longer. However, their durability is influenced by several factors.
Factors affecting longevity include chewing habits, oral hygiene practices, and the type of sealant material used. Regular dental check-ups are important as they allow the dentist to monitor the condition of the sealants and address any chipping or wear. If a sealant becomes damaged or wears down, it can be repaired or reapplied to maintain continuous protection.
Cost and Other Important Considerations
The cost of dental sealants can vary, generally ranging from $30 to $60 per tooth without dental insurance. This price can fluctuate based on geographic location, the dental practice, and the specific material used. While this represents an upfront investment, sealants are often more cost-effective than treating cavities, which can involve more expensive procedures like fillings, crowns, or root canals.
Regarding dental insurance, coverage for adult sealants is less common than for children, though some plans may offer partial or full coverage. Sealants are classified as a preventative service, and whether they are covered for adults often depends on the specific policy and age limitations. It is advisable to contact your dental insurance provider directly to understand your specific benefits. While rare, some individuals might experience temporary tooth sensitivity after application, or the sealant could detach, necessitating reapplication. Sealants serve as a preventative measure and do not substitute for consistent oral hygiene practices.
