What Are Dental Sealants?
Dental sealants are a thin, protective coating applied to the chewing surfaces of the back teeth—molars and premolars. These sealants are designed to fill the deep grooves and pits, preventing food particles and bacteria from settling and causing cavities. The material used for dental sealants is typically a resin-based compound, which hardens quickly and provides a durable barrier.
Composition of Dental Sealants
Most dental sealants are composed of a plastic resin that bonds effectively to tooth enamel. This resin is either clear or tooth-colored, which makes it cosmetically appealing. Some sealants may contain fluoride, which can provide an additional decay-fighting benefit.
How Sealants Work
Once applied, dental sealants create a smooth, protective surface over the tooth enamel. This surface is easier to clean and reduces the risk of plaque accumulation in the grooves of the teeth. By acting as a physical barrier, sealants protect teeth from the acid and bacteria that contribute to decay.
The Benefits of Dental Sealants
Dental sealants offer numerous advantages, making them a highly recommended preventive measure in dentistry. They are especially beneficial for children and teenagers but can also be advantageous for adults with specific needs.
Prevention of Cavities
The primary benefit of dental sealants is their ability to prevent cavities. Studies have shown that sealants can reduce the risk of decay in molars by nearly 80%. This is particularly important for children and teenagers, who are most prone to cavities in the pits and fissures of their back teeth.
Cost-Effectiveness
Applying dental sealants is a cost-effective approach to dental care. By preventing cavities, you can avoid more expensive and invasive treatments such as fillings, crowns, or root canals. At our Hillsboro clinic, we offer competitive pricing to make this preventive measure accessible to families throughout the 97124 area and beyond.
Easy and Painless Application
The process of applying dental sealants is straightforward and painless. It involves cleaning the tooth thoroughly, applying an acidic gel to roughen the surface for better bonding, rinsing off the gel, and then painting the sealant onto the enamel. The sealant hardens quickly using a special curing light.
The Procedure for Applying Dental Sealants
Understanding the procedure for applying dental sealants can alleviate any concerns patients might have about the process. Here’s a detailed look at what to expect during a sealant application at our Hillsboro office.
Initial Cleaning and Preparation
The first step in applying dental sealants is to clean the teeth thoroughly. This ensures that no food particles or plaque remain on the surface, which could interfere with the bonding process. Our hygienists use specialized tools to ensure each tooth is spotless.
Etching the Tooth Surface
Once the tooth is clean, an etching solution is applied to the enamel. This slightly roughens the surface, allowing the sealant to adhere more effectively. The etching solution is rinsed off after a few seconds, and the tooth is dried.
Sealant Application and Curing
The dental sealant is then painted onto the tooth’s surface. It flows into the grooves and fissures, creating a protective layer. A special curing light is used to harden the sealant quickly. The entire process is quick, often taking only a few minutes per tooth.
Who Should Get Dental Sealants?
While dental sealants are most commonly recommended for children and teenagers, adults can also benefit from them under certain circumstances. Let’s explore who should consider getting dental sealants.
Children and Teenagers
The CDC reports that children with sealants have fewer cavities than those without, a finding supported by the American Academy of Pediatric Dentistry. The ideal time to apply dental sealants is when the first molars appear, around age six, and again when the second molars come in, around age 12.
Adults with Deep Grooves
Adults who have deep grooves and fissures in their teeth but no current decay or fillings in those areas may also benefit from dental sealants. This preventive measure can protect their teeth from future decay.
Patients with Special Needs
For patients with special needs or those who find it challenging to maintain regular oral hygiene, dental sealants can provide an added layer of protection against cavities.
The Longevity of Dental Sealants
Dental sealants are durable and can effectively protect teeth for several years. However, their longevity depends on several factors, including oral hygiene practices and dietary habits.
Maintenance and Care
To maximize the lifespan of dental sealants, patients should maintain good oral hygiene, including brushing twice a day and flossing daily. Regular dental check-ups are also crucial, as our team can monitor the condition of the sealants and reapply them if necessary.
Dietary Considerations
Avoiding hard or sticky foods can help preserve dental sealants. Foods like candy, ice, and popcorn can dislodge or wear down the sealants over time. Encouraging children to eat a balanced diet will not only benefit their overall health but also help maintain their dental sealants.
Addressing Common Concerns About Dental Sealants
Despite their benefits, some patients have concerns about dental sealants. Here we address common questions and misconceptions.
Are Sealants Safe?
Yes, dental sealants are safe and have been used effectively for decades. They are made from materials that are biocompatible and have been extensively tested for safety.
Do Sealants Affect the Natural Tooth?
Dental sealants do not damage the natural tooth structure. They act as a protective layer and can be removed without affecting the enamel beneath.
How Often Should Sealants Be Checked?
Sealants should be evaluated during regular dental check-ups. Our Hillsboro team will assess their condition and determine if reapplication is necessary.

Sealants vs. Fluoride: Which Does Your Child Need?
Both dental sealants and fluoride treatments prevent cavities, but they work through different mechanisms and protect different tooth surfaces.
Fluoride strengthens enamel by incorporating into the crystal structure as fluorapatite, which resists acid dissolution better than natural hydroxyapatite. Fluoride works best on smooth surfaces — the front, back, and sides of teeth — where cavities form from acid exposure. We apply professional fluoride varnish (5% sodium fluoride) at cleaning appointments. The varnish remains on teeth for 4–6 hours, delivering concentrated fluoride for remineralization.
Children also receive fluoride through fluoridated tap water (Hillsboro water contains 0.8–1.0 ppm optimal fluoride levels) and fluoride toothpaste. This topical fluoride provides excellent protection for smooth surfaces.
Dental sealants protect the chewing surfaces of back teeth — molars and premolars — where deep pits and fissures trap food and bacteria. Toothbrush bristles cannot reach into these microscopic grooves, making them the most cavity-prone areas in children’s mouths. The resin-based sealant material flows into the grooves and hardens into a smooth, protective surface that prevents bacterial colonization.
Studies show that sealed molars have 80% fewer cavities than unsealed molars. The Centers for Disease Control (CDC) reports that sealants prevent 80% of cavities in back teeth for two years after application and continue to protect against 50% of cavities for four or more years.
Your child needs both. Fluoride and sealants complement each other by protecting different tooth surfaces. Our Hillsboro practice apply fluoride varnish at every cleaning appointment (every 6 months) and recommend sealants on permanent molars as soon as they fully erupt (first molars at age 6, second molars at age 12). Individual costs vary — contact us for your personalized treatment plan.
Most dental insurance plans cover sealants at 80–100% for children under age 14–16 (coverage age limits vary by plan). Oregon Health Plan (OHP/Medicaid) covers sealants for children through age 20. Fluoride treatments are typically covered for children through age 18.

FAQs: Dental Sealants in Hillsboro, Oregon
Are dental sealants safe?
Yes. Sealants have been used in dentistry since the 1960s and are FDA-approved. The materials are BPA-free or contain trace amounts well below any level of concern. Every major dental and medical organization endorses their use for cavity prevention.
Do dental sealants hurt?
Not at all. No drilling, no needles, no anesthesia. The application feels like someone painting your tooth with a small brush. Most kids don’t even realize it’s happened.
My child already brushes well. Do they still need sealants?
Even excellent brushing can’t fully clean the deepest grooves in molars. The bristles are simply too wide to reach the bottom of narrow pits. Sealants fill those gaps and give your child’s brushing a meaningful assist.
Do adults benefit from dental sealants?
Many adults do, particularly those with deep grooves, dry mouth, or a pattern of cavities on chewing surfaces. Insurance coverage for adults varies, but the protection is the same regardless of age.
How long do dental sealants last?
Sealants typically last 5–10 years. Some wear down sooner if your child grinds their teeth or chews on hard objects like ice or pens. Dr. Ostovar checks sealants at every cleaning and reapplies them if they chip or wear through. The CDC reports that sealants reduce cavities in molars by nearly 80% during the years they remain intact — so maintaining them is worth the effort.
How much do dental sealants cost?
Sealants usually cost $30–$60 per tooth. Most dental insurance plans cover sealants for children at 100% as a preventive benefit, typically up to age 14–18 depending on your plan. For adults, coverage varies. Even without insurance, sealants are far less expensive than treating a cavity, which can cost $150–$300 for a filling — or much more if decay progresses to need a root canal and crown.
Can sealants be applied over a cavity?
No. Sealants only work on healthy tooth surfaces. If a cavity has already formed, Dr. Ostovar needs to remove the decay and place a filling first. Sealing over a cavity would trap bacteria inside and allow the decay to continue growing underneath. This is why we recommend sealants as soon as permanent molars come in — before cavities have a chance to start.
When should my child get dental sealants?
The ideal time is shortly after the permanent molars erupt. First molars come in around age 6, and second molars around age 12. Applying sealants right away protects the teeth during the highest-risk cavity years. Dr. Ostovar evaluates your child’s cavity risk and recommends the best timing during their regular checkups.
