Sealants

Dental sealants are a clear protective layer that covers the deep grooves in your back teeth. These specialized barriers shield the natural grooves and pits of your molars and premolars from cavity-causing bacteria and food particles. At MacPhail Signature Smiles, Dr. MacPhail, DDS recommends sealants as a preventive measure for both children and adults who want to maintain optimal dental health. This simple, painless procedure can save you from the discomfort and expense of treating cavities later on.
What are dental sealants and how do they work?
Dental sealants are plastic coatings applied to the chewing surfaces of your back teeth, specifically molars and premolars. These teeth often have deep grooves and depressions that can trap food particles and bacteria, making them prime targets for decay. Sealants fill in these grooves, creating a smooth surface that’s easier to clean with regular brushing. This creates a protective shield that blocks food and bacteria from settling into hard-to-clean areas.
When properly applied and maintained, dental sealants can significantly reduce your risk of developing cavities in treated teeth. This preventive treatment is particularly valuable for children as soon as their permanent molars emerge; however, adults with cavity-prone teeth can also benefit significantly from this protective measure.

Protecting your Teeth, Brightening Your Smile
Sealants are typically used to protect the back teeth, where tooth decay happens most frequently. A sealant is a material made of a plastic resin that is generally placed on the molars. The sealant’s plastic resin sticks in the grooves and depressions of the back teeth’s chewing surfaces.

The sealant is essentially a barrier and it protects the enamel from bacteria that, when combined with sugar, produces acid that eats a hole in your tooth causing a cavity. Sealants are useful because while flossing and brushing removes bits of food, there are usually still bacteria left wedged deep in the back teeth. Effective sealants help prevent bacteria from ever getting stuck in these hard-to-reach nooks.

Finally, we use a special curing light to harden the sealant into a durable, protective shield.

FAQs
What are dental sealants?
Dental sealants are thin, plastic coatings applied to the chewing surfaces of back teeth (molars and premolars) to prevent tooth decay. They work by filling in the deep grooves and depressions where food particles and bacteria typically get trapped. Once applied, the sealant forms a protective shield over the enamel, creating a smooth surface that’s easier to clean with regular brushing. It’s a simple step that goes a long way in preventing cavities.
How long do dental sealants last?
Dental sealants typically last between 5 to 10 years with proper care and maintenance. Their longevity depends on several factors, including your chewing habits and the location of the sealed teeth. During regular dental check-ups, your dentist will examine your sealants for signs of wear or chipping and can repair or replace them as needed. Some patients may retain their sealants for even longer periods if they maintain good oral hygiene habits and avoid chewing on hard objects like ice or hard candy.
What are dental sealants made of?
Dental sealants are primarily made of dental-grade resin, a type of plastic material specifically designed for oral use. This BPA-free material bonds directly to the tooth enamel and hardens when exposed to a special curing light. Modern sealant materials are available in clear, white, or slightly tinted formulations that blend naturally with your tooth color. These materials have been extensively tested for safety and effectiveness in preventing tooth decay while withstanding the forces of everyday chewing.
Are dental sealants safe?
Yes, dental sealants are extremely safe for patients of all ages. The materials used in modern sealants have been thoroughly researched and approved by dental health organizations worldwide. While some earlier sealant formulations contained trace amounts of BPA, today’s products typically use BPA-free materials that eliminate this concern. The application process is completely non-invasive, requiring no removal of tooth structure or alteration of your natural teeth. The benefits of cavity prevention far outweigh any minimal risks associated with sealant application.
Do dental sealants hurt?
No, getting dental sealants is a completely painless procedure that doesn’t require any drilling or anesthesia. You might notice a slight taste from the etching solution or the sealant material, but there is no discomfort during or after the application. The entire process feels similar to having your teeth cleaned – you’ll simply feel the dentist working on your teeth without any pain. This is why sealants are an ideal preventive treatment for patients of all ages, including young children who might be anxious about dental procedures.
