What Are Dental Sealants and How Long Do They Last?
July 15, 2025 9:00 amDental sealants act like shields for your teeth, protecting the chewing surfaces of back teeth. These thin plastic coatings fill in grooves and pits—places where bacteria love to hide. At Ryan Dental in Olathe, KS, Dr. William Ryan and Dr. Randy Regier frequently recommend sealants for kids and adults who want extra cavity protection.
Why Tooth Grooves Need Extra Protection
Molars and premolars have natural pits that can trap food bits and plaque. Even diligent brushing doesn’t always reach inside those fissures. That’s where sealants step in. Applied to the chewing surface, they smooth out those crevices, making it harder for decay to settle in.
Sealants are especially helpful for children, whose back teeth are still maturing. But adults with deep grooves or cavity history also benefit.
How Sealants Are Applied
The process is quick and comfortable:
1. Teeth are cleaned and dried.
2. A special gel roughens the surface so the sealant bonds better.
3. The sealant liquid is painted into grooves.
4. A curing light hardens the coating in seconds.
5. Chewing surfaces look glossy and smooth afterward.
No shots, no drilling—just a painless layer of protection.
How Long Do Sealants Last?
Sealant longevity can depend on factors like eating habits, chewing forces, and how well you care for them. Most last around 5 to 10 years. Regular dental exams let Dr. Ryan or Dr. Regier check their condition. If a sealant shows wear or cracks, it can be cleaned and reapplied to maintain effectiveness.
Who Benefits Most from Sealants?
Children and teens often top the list because their back teeth are most vulnerable. But adults with deep grooves or new cavities can benefit too. Sealants are an easy way to reduce risk—especially if you have a history of decay despite good hygiene. Even more, they are typically covered for children by dental insurance, making it an even easier choice.
Maintain Sealants with Smart Habits
Good brushing and flossing are still necessary. Sealants don’t protect smooth surfaces or between teeth. Checkups every six months ensure sealants are intact and working well. Avoid biting hard foods like ice or unpopped popcorn kernels—they can chip or wear down sealants.
