A fast, painless way to shield molars from decay.​​
​
Dental sealant treatments can reduce the risk of cavities in permanent molars by 80% for the first two years after application. ​At Dentini, we can apply protective dental sealants in minutes to help avoid fillings later. ​
Protects molars for up to 10 years
Applied in one visit, no drilling

What are Dental Sealants?
Before
After
Dental sealants are thin, protective coatings applied to the chewing surfaces of back teeth (molars and premolars) to prevent decay. ​It's a preventative treatment.
Your child's dentist may recommend sealants if your child's teeth have unusually deep grooves that are hard to clean with normal brushing. They might also be recommended if your child struggles to brush well on their own, or if diet or lifestyle puts your child at higher risk for cavities.
​​
How Much do Dental Sealants Cost with Insurance?
​
Many insurance plans cover sealants 100% as a preventive service. ​
Without insurance, costs in Houston average from $80-100 per tooth according to Delta Dental's cost estimators. Your dental team will confirm any out of pocket costs before treatment begins. ​

How Are Dental Sealants Applied?
Dental sealants are done in-office. The application of dental sealants is a non-invasive, painless process. It does not require any drilling or numbing (needles), making it a very comfortable experience for children.​​​

Before Applying
Dental Sealant
First, a high-risk area is identified.
​
Cavities love to grow in the deep grooves of molars, where food gets trapped and bacteria can grow. Adding a seal protects the spots that are most difficult to clean with a tooth brush.
​
Even if your kid is a pro at brushing, toothbrush bristles can struggle to reach the very bottom of those skinny canyons where "sugar monsters" like to hide and throw a cavity party.
Applying a Dental Sealant

Dental sealants are applied in-office, and only take a few minutes.
There's no drilling. Numbing may not even be needed. It boils down to four simple steps:
​​​
-
Your tooth is cleaned and dried. Think of adding a cool sticker to a water bottle. If the bottle is dusty or wet, the sticker won't stay. Dentists clean and dry a tooth before applying a sealant.
-
A bit of blue gel goes on first. It sits on your tooth for a minute. This gets the tooth ready to connect to the sealant.
-
The dentist "paints" the seal on. Think of pouring syrup on a waffle. As the dentist paints, the liquid flows into the deep holes in your tooth. This fills them up so bacteria and food can't get inside.
-
A bright blue light dries it up. The light tells the liquid to "freeze." It makes the liquid hard, and only takes about 30 seconds. Once the light clicks off, the "shield" is fully charged and ready to go.
The liquid hardens into a smooth, invisible layer that helps prevent decay in hard-to-clean areas.

Are Dental Sealants Safe?
Yes, dental sealants are considered highly safe. They've been used safely for over 40 years.
​
​While some dental sealants contain trace levels of BPA from their manufacturing process, the Science Institute at the American Dental Association roperts BPA exposure from dental sealants is 100x lower than exposure from BPA in the air.
Dental Sealants versus Fluoride
Sealants and fluoride solve different problems. Most dentists will recommend both, but for different reasons.​
​
Sealants offer physical protection. Picture a shield being placed over a back teeth. Food is blocked from entering the tiny caves of the tooth. It's a physical barrier. Dentists use them on specific high-risk spots, like molars with extra-deep grooves that a tooth brush can't clean easily.
​
Fluoride strengthens the tooth. It's not a physical barrier. It's a chemical that helps your teeth rebuild themselves after acid, sugars, or bacterials wear them out. Fluoride works on the entire tooth, not just one spot.
How do dentists decide which to use? Most will use both. Sealants are applied when dentists see a deep spot in molars where food or bacteria can hide. Fluoride is used to support overall tooth strength and repair, and helpful if someone has higher cavity risks or is a frequent snacker.​​​
Fluoride | Sealant | |
|---|---|---|
A natural mineral "vitamin" for teeth | What Is It | A thin, protective "plastic" coating |
Prevents cavities on smooth sides and between teeth. | Protection Type | Prevents cavities in hard-to-clean "pits" and "fissures" |
On every surface of all teeth in your mouth. | Where It's Used | On chewing surfaces of back teeth (molars). |
Soaks into the enamel to make tooth surface stronger. | How It Works | Fills in deep grooves to keep food and bacteria out. |
Applied as a sticky varnish, foam, or from toothpaste or water. | Application | Painted on as a liquid then hardened by special UV light |
Usually applied every 6 months during a cleaning | How Long it Lasts | 5-10 years with proper care |
Natural minerals | Ingredients | Medical grade BPA-free resin |
Dental Sealant Recovery & Aftercare
There's usually no downtime required after a dental sealant treatment.
Most kids can return to school or play immediately after their visit.
​
Sometimes, kids notice their tooth feels extra slippery, or that it feels a little funny to bite down where the seal was applied. This is common when sealants are fresh. After a few days, the mouth adjusts and sealants become unoticable.
​
Can my child eat after dental sealants?
​
Yes! Because sealants are hardened instantly with a special UV light, children can eat and drink right away, though we recommend softer foods for the first few hours.
How Long do Dental Sealants Last?
Dental sealants can last from 5 to 10 years with proper care.
​​
They aren't invincible. To keep dental sealants protecting longer, watch out for:
​​
-
Chewing hard things like ice, popcorn kernels, or lollypops that can crack the seal
-
Super sticky treats like taffy, caramel, or gummies that can "grab" the seal and pull it loose
-
Grinding teeth (talk to your dentist about options like mouth guards)
​
Your dentist will check in on them at your 6-month cleanings. If they spot any damaged dental sealants often be "patched" or re-applied where needed.
​
Types of Dental Sealants
There are two main types of dental sealants: resin-based sealants and glass ionomer sealants. They each behave differently on teeth.
Resin-based sealants are plastic-like coatings on the tooth's surface. They are a strong, smooth seal that can last years. A tooth has to be totally dry for resin-based sealants to stick properly. This makes them harder to apply on younger or squirmy kids, since a curious tongue can complicate the process. For older and cooperative patients, resin-based sealants are a durable protector for molars.
Glass ionomer sealants are more forgiving. They connect chemically to the tooth, which means they can tolerate a bit more moisture or saliva being in the way. This is great for younger kids, wiggly patients, or molars that are still coming in and closer to the gums. The downside? They're not as durable. Glass ionomer sealants can chip or wear down faster.
Glass ionomer sealants have a hidden super power: they release fluoride over time. This helps rebuild tooth enamel and fight off decay. Some even recharge with fluoride from toothpaste. Dentists often recommend this for patients at higher cavity risk.
Dentists often pick based on the case. If a tooth is dry and patient is cooperative, resin wins for its strength and longevity. If moisture control is trickier or decay risk is higher, glass ionomer is often a practical fluoride-delivering backup. ​​​
Wondering if Your Child Could Benefit from Sealants?
The best way to know for sure is a quick evaluation during a routine dental check-up.
​The most common time for sealants starts around ages 5-7. That's when the first set of permanent molars come in. Then again around ages 11-14 when the second set of molars appear.
​
Dentini is accepting new patients. At your child's first evaluation, we'll examine their mouth closely. We may ask simple questions to evaluate risk factors like:
​
-
Has your child had a cavity before?
- Do they drink lots of juice or soda?
-
Are they struggling to brush well?
-
Does your child eat many sticky or mushy snacks?
​​​
If we think dental sealant treatment is right, we'll explain everything. We'll answer as many questions as you have. You'll always be educated and in control of your child's dental care plan.
​
Already a Dentini patient? Your child's dental team is already monitoring for risk factors and signs that dental sealants may be needed. We'll let you know if it may be needed, and go over everything with you before any treatment takes place.
