Dental Sealants in Scottsdale, AZ
 Dental sealants are a thin protective coating we paint into the grooves of the back teeth at Dental Works in Scottsdale, AZ, and they are one of the few things in dentistry that prevents a problem instead of repairing one. The appointment takes minutes, nothing gets numbed, and nothing is removed from the tooth.
Most people picture a kid in the chair, and children are the group sealants were designed around. But a sealant goes on any molar with grooves deep enough to trap what a toothbrush cannot reach, and plenty of adults have exactly that. If you are in your forties with back teeth that have never been filled, the grooves are a reason to protect what you have rather than assume you are past the point of needing to.
Sealants are one piece of a preventive routine, not a substitute for one. They work alongside cleanings, fluoride, and the flossing they cannot help with, which is why they belong in the same conversation as the rest of our family dentistry care rather than off on their own.

What Dental Sealants Are and Who Gets Them
 The chewing surface of a molar is not flat. It is a landscape of pits and grooves, some of them narrower than a single toothbrush bristle, which is why brushing does not clean them out no matter how long you go at it. A sealant is a liquid resin that flows into those grooves and hardens under a blue light, turning a surface you cannot clean into one you can.
The CDC puts the effect at roughly 80 percent fewer cavities in sealed back teeth over the first two years, easing to about 50 percent through year four. Those are meaningful numbers and they are also not a guarantee. A sealant covers the chewing surface. It does nothing for the sides of the tooth where it meets its neighbor, which is where floss earns its keep.
Who Actually Benefits
The criterion is the tooth rather than the birthday. Who tends to gain the most:
- Children and teens – first permanent molars arrive around age six and the second set around twelve, and the window right after they come in is when sealing them is easiest and most useful
- Adults with deep grooves – a back tooth that has never been filled but has sharp, deep grooves is a tooth with something left to protect
- Anyone with a decay history on chewing surfaces – a pattern of cavities in the grooves is the clearest signal that sealants will pay off
- Patients with dry mouth – less saliva means less natural rinsing, and medication-related dry mouth raises decay risk at any age
Who does not benefit is a tooth where decay has already broken through the enamel. A sealant is not a lid. Once the groove has opened up, that tooth needs a small tooth-colored filling instead, and we seal the neighbors that are still intact.
Sealants Are Not Fillings, and Not Bonding
All three use a resin, which is where the confusion starts. A filling replaces tooth structure that decay already destroyed. Bonding reshapes a tooth for appearance. A sealant does neither: it sits on top of intact enamel, and nothing is removed to place it. If you are looking at a treatment plan with all three on it, they are answering three different problems.
Your Preventive Care Team in Scottsdale
Sealants are quick and inexpensive, which makes them easy to recommend reflexively rather than selectively. Dr. Mary Ann Work serves as an investigative dentist for the Arizona State Dental Board, a role that involves reviewing what other dentists recommended and why. That perspective sits behind how sealants get recommended here: on the teeth that need them, at the age they help most. More on Dr. Mary Ann Work’s bio page.
Dr. Terry Work founded the practice in 1994 and now treats the children of patients he first saw as children themselves, which is the working definition of a family practice. His bio page has the background.
A sealant placed here gets examined at every recall by the same practice that placed it, and the call on whether it needs redoing sits with the same two dentists year after year. There is no handoff where someone new to the tooth has to piece its history back together.
What a Sealant Appointment Looks Like
Sealants usually go on during a regular checkup rather than as their own visit. A single tooth takes a few minutes, and even a full set of molars adds less time than most people expect.
| 1. |
Clean the tooth - we polish the chewing surface and rinse away whatever is sitting down in the grooves
|
| 2. |
Dry and isolate - saliva reaching an etched surface is the most common reason a sealant fails early, so the tooth stays isolated from here on
|
| 3. |
Etch the enamel - a mild gel roughens the surface at a microscopic level for a few seconds, then rinses off completely
|
| 4. |
Paint on the sealant - the resin flows into the grooves on its own and we work it out to the edges
|
| 5. |
Cure and check the bite - a blue light hardens it in seconds, then you bite down and we adjust anything sitting high |
No anesthesia, no removal of tooth structure, nothing sharp involved. The only complaint we hear with any regularity is that the etching gel tastes sour for a few seconds, which is a manageable problem.
Sealants then get inspected at every dental exam. They chip, they wear thin at the edges, and a partially missing sealant deserves more attention than an obviously missing one, because it hides what is underneath. Repairing one takes about as long as placing it did.
What Sealants Actually Prevent
A sealed molar that never gets a cavity is an invisible outcome. Nobody notices the filling they did not need, the appointment they did not book, or the tooth that still has all its original structure at sixty.
That last one is worth sitting with. Every time a tooth gets filled, some of it comes out and does not come back, and fillings do not last forever, so each replacement takes a little more. A tooth that never enters that cycle stays ahead for life, and that compounding is the argument our tooth loss prevention page makes at every stage.
| • |
Protection where cavities actually happen - the CDC puts nine out of ten cavities in school-age children in the back teeth, which is exactly where sealants go
|
| • |
Nothing lost to place one - a sealant goes onto intact enamel, so no healthy tooth is removed for it
|
| • |
A fraction of the cost of the filling it prevents - and a fraction of the chair time
|
| • |
An easy first procedure for an anxious child - a few minutes with a light beats a first visit that involves anesthesia
|
| • |
A checkpoint twice a year - a sealed tooth gets looked at closely at every recall whether or not anything is wrong |
What sealants do not do is cover the whole tooth. They sit on the chewing surface only. Cavities between teeth are just as common and just as invisible without an x-ray, and no sealant reaches them. Floss is still the tool for that.
Why Scottsdale Families Choose Our Office
Two dentists, both here since the nineties, both seeing the same families year over year. That matters more on preventive work than it does on a crown, because prevention is a judgment call about risk, and risk is easier to judge once you have watched a mouth for a decade.
We do not seal every tooth by default. Some molars have shallow, self-cleaning grooves and genuinely do not need it. Some patients have a decay pattern that says seal everything you can. Telling those apart is the whole job, and it is why we look before we recommend instead of quoting sealants as a package.
Sealants also do real work for patients who have a hard time brushing thoroughly, which makes them a natural fit alongside our special needs dentistry program. And because they go on during a visit you were already having, nobody has to make a separate trip across town for them.
Sealant Cost and Insurance Coverage
 Sealants are among the least expensive things we do, which is most of the argument for them. What moves the number at all is simply how many teeth get sealed.
Coverage is where it gets uneven, and it is worth knowing before you assume. Most dental plans cover sealants for children, often with an age cap somewhere in the teens and sometimes limited to first and second molars only. Adult sealants are frequently not covered at all, even when they are clearly the right call clinically. That is a policy decision by the insurer, not a clinical one.
Our Dental Savings Program lists dental sealants among its discounted services, which matters most for exactly the adults that insurance leaves out. Call (480) 391-0099 with your plan details and we will tell you what applies before anything gets scheduled.
Schedule a Sealant Visit in Scottsdale
Sealants go on easiest when a molar has just come in, which for a six-year-old or a twelve-year-old means right now. For an adult with back teeth that were never filled, it is about keeping them that way. Call (480) 391-0099 or use our Request an Appointment page.

Frequently Asked Questions
Does getting a sealant hurt?
No, and there is nothing to numb. For a child who is nervous, the useful thing to know is that a sealant is the appointment most likely to convince them the dentist is fine: they sit down, a light comes on, and they leave. It makes a good first procedure for a kid who has only ever had cleanings.
How long do dental sealants last?
Several years for most people, and the range is wide because it comes down to the bite. A sealant on a tooth that grinds at night wears faster than one that does not. The failure to catch is partial loss rather than total loss, because a sealant missing one edge looks fine and leaves the groove underneath exposed. That is what the check at every recall is for.
Are sealants only for children?
No, though insurance often behaves as if they are. The clinical criterion is the tooth, not the birthday: a molar with deep grooves and no decay is a candidate at any age. What changes with age is that by forty or fifty most back teeth have already been filled, and a filled tooth does not get sealed. If yours have not been, that is the reason to ask about it.
Is there BPA in dental sealants?
BPA is not an ingredient in dental materials, but trace amounts can leach from freshly cured resin and show up in saliva for a few hours afterward. The ADA and the FDA have both concluded that exposure at that level poses no known health risk, and wiping and rinsing the surface right after curing reduces it further, which is standard practice. If you are pregnant and would rather talk it through before we place any resin, say so and we will.
If my child has sealants, can we ease up on flossing?
No, and this is the misunderstanding most worth heading off. Sealants cover the chewing surface. They do nothing at the spot where one tooth touches the next, and that contact point is where a large share of cavities in kids and teens actually form. Sealants plus no flossing is a trade that loses.
What if a sealant comes off and we do not notice?
That is a real scenario rather than a hypothetical, and it is what the twice-a-year check exists for. A sealant can wear thin or lose an edge with no symptom at all. Nothing hurts and nothing looks different from across a room. Six months is a short enough gap that a lost sealant rarely becomes a cavity before we catch it, which is a good argument for not stretching those visits out.
Can a tooth that already has a filling get a sealant?
Usually not on the same surface, and not because of a rule. The filling has already taken over the groove that would have been sealed, so there is nothing left there to protect. What can happen is sealing a different surface of that same tooth, or sealing the neighbors that are still intact. It is a per-tooth decision rather than a per-mouth one.
Is it worth coming to Dental Works in Scottsdale just for sealants?
You would not come just for sealants and we would not ask you to. They go on during a teeth cleaning visit you were having anyway. The reason to have them placed here instead of wherever is convenient is that the recommendation comes from someone who will still be checking that tooth in five years, and knowing you will be the one looking at it later changes what you recommend now.
