Cavities are one of the most common health problems affecting children and teenagers — but they are also one of the most preventable. Dental sealants are one of the simplest, most effective tools we have for protecting vulnerable teeth from decay before it ever has a chance to develop. At Evergreen Dental in Glen Burnie, Maryland, we recommend sealants as part of a comprehensive preventive care strategy for children, teenagers, and adults who want an extra layer of protection for their back teeth.
The procedure is quick, completely painless, and requires no drilling or anesthesia — making it one of the easiest and most rewarding investments you can make in your family's oral health.
The most common candidates for dental sealants are children between the ages of 6 and 14. The first permanent molars typically erupt around age 6, and the second permanent molars around age 12. Sealing these teeth as soon as they come in — before decay has a chance to develop — provides protection during the cavity-prone childhood and teenage years. Studies show that sealants can reduce the risk of decay in back teeth by nearly 80%.
Teenagers
Teenagers face a particularly high risk of cavities due to dietary habits, less consistent oral hygiene, and the presence of newly erupted permanent molars. Sealants provide meaningful protection during these years when cavity risk is at its peak.
Adults
Sealants are not exclusively for children. Adults who have deep grooves in their molars and no existing decay or fillings in those teeth can benefit from sealants just as much. If you have cavity-prone back teeth or simply want an added layer of protection, ask our team whether sealants are a good option for you.
The Dental Sealant Process
Cleaning
The teeth receiving sealants are thoroughly cleaned to remove any plaque or debris from the surface and grooves.
Preparation
The chewing surfaces are lightly etched with a gentle acidic solution to create a slightly rough texture that helps the sealant material bond securely to the tooth. The tooth is then rinsed and dried completely.
Sealant Application
The liquid sealant material is carefully painted onto the chewing surface of the tooth, flowing into all the grooves and pits.
Curing
A special curing light is used to harden the sealant material in just a few seconds, bonding it firmly to the tooth surface.
Check & Polish
We check the sealant for complete coverage, verify your bite feels natural and comfortable, and make any minor adjustments needed. The entire process for all four molars typically takes less than 30 minutes.
We typically recommend sealants as soon as the first permanent molars erupt — usually around age 6 — and again when the second permanent molars come in around age 12. Sealing these teeth as early as possible provides protection during the years when cavity risk is highest. However, sealants can be beneficial at any age if the teeth are free of decay and fillings.
Not at all. Dental sealants involve no drilling, no needles, and no anesthesia. The process is completely painless and is typically very well tolerated by children of all ages, including those who feel anxious about dental visits. Most kids are surprised by how quick and easy it is.
No. Sealants are a preventive measure designed to protect teeth that are healthy and free of decay. If decay is already present, it must be treated with a filling before any sealant can be placed. This is why regular exams and early detection are so important — catching teeth before decay develops gives us the opportunity to protect them with a sealant.
Yes, immediately. There is no recovery time and no dietary restrictions after sealant placement. Your child can eat and drink normally right away. We simply recommend avoiding very hard foods like ice or hard candy that could chip the sealant material.
Sealants are durable but not permanent. They typically last 5–10 years and are checked at every routine exam. If a sealant shows signs of chipping or wear, or if an area is no longer fully covered, we can reapply it quickly and easily to restore full protection.
Many dental insurance plans cover sealants for children up to a certain age — typically up to age 14 or 16 — as they are recognized as an important preventive measure. We will verify your child's benefits before the appointment and let you know exactly what is covered. For uninsured patients, sealants are very reasonably priced and represent excellent value compared to the cost of treating cavities.
Yes. While sealants are most commonly placed on children's teeth, adults with deep grooves in their back teeth and no existing decay or fillings in those areas can absolutely benefit from sealants. If you are concerned about your cavity risk or simply want extra protection for your back teeth, ask our team whether sealants are a good fit for you at your next visit.
