Dental Sealants in Glendale, AZ: Powerful Protection Against Tooth Decay
Brushing and flossing are the foundation of a healthy mouth, but even the most diligent routine cannot fully protect every surface of every tooth. The chewing surfaces of back teeth are covered in deep pits and grooves that trap food and bacteria in spaces too narrow for a toothbrush bristle to reach. At A & A Family Dentistry, dental sealants in Glendale, AZ offer a fast, painless, and highly effective solution to this problem. A thin protective coating is applied directly to those vulnerable surfaces, creating a physical barrier that blocks decay before it has the chance to start. Whether for a child getting their first permanent molars or an adult looking to protect teeth that have not yet developed cavities, our Glendale team is ready to help.
What Are Dental Sealants?
Dental sealants are thin, tooth-colored acrylic coatings bonded directly onto the chewing surfaces of the back teeth, primarily the premolars and molars. These are the teeth most vulnerable to cavities because of the complex network of grooves, fissures, and depressions across their surfaces.
The Centers for Disease Control and Prevention (CDC) reports that school-age children without sealants have almost three times more cavities in their first molars than children who have them. That is a significant difference achieved with a quick, non-invasive, in-office procedure.
Sealants work by filling in the natural depressions on the tooth surface so that food particles and plaque cannot accumulate there. The sealed surface becomes smooth and easy to clean, and the bacteria that cause decay are denied a foothold. They hold up reliably under the forces of normal chewing and, with proper care, can last many years before reapplication becomes necessary.
Why the Back Teeth Are So Vulnerable
Most people are surprised to learn that the majority of cavities in children and teens occur on the chewing surfaces of the back teeth rather than between teeth or at the gumline. The reason is straightforward: the anatomy of molars and premolars works against them.
- The grooves on molar chewing surfaces can be as narrow as a single toothbrush bristle, making thorough cleaning nearly impossible no matter how carefully you brush
- Food residue and bacteria settle into these grooves after every meal and are protected from both mechanical brushing and the natural cleansing action of saliva
- Acid-producing bacteria have extended contact with enamel in these pockets, accelerating the decay process
- Decay in these grooves is often well established before it becomes visible or causes symptoms
Once decay reaches a certain depth, it requires a dental filling to restore the tooth. Sealants prevent that decay from starting in the first place, protecting both the tooth and the patient from an avoidable restorative procedure.
Who Should Get Dental Sealants in Glendale, AZ?
While sealants are most commonly associated with children, they are beneficial for patients of various ages and risk profiles. Our team at Dr. Ardalan’s practice evaluates each patient individually and recommends sealants based on tooth anatomy, decay history, and overall risk level.
Children and Teenagers
The ideal time to place sealants is shortly after the permanent molars erupt, before any decay has had a chance to develop. For most children this means two separate applications:
- Around age 6: When the first permanent molars erupt behind the baby teeth
- Around age 12: When the second permanent molars come in
Sealing these teeth as soon as they are fully erupted and accessible maximizes the protective benefit during the years when children are most cavity-prone. For more about how we care for younger patients, visit our child dentistry page.
Adults Without Existing Decay or Fillings
Adults with deep grooves on back teeth that have not yet developed cavities are also strong candidates. There is no age limit for sealants, and the procedure is just as effective for adults as it is for children. If your molars have complex anatomy and a history of recurring decay, sealants offer a practical, proactive solution.
Patients at Higher Cavity Risk
Patients with certain medical conditions, dry mouth from medications, or a history of frequent cavities may benefit from sealants across more teeth than the average patient. During your routine cleaning and exam, we assess your individual risk level and make personalized recommendations accordingly.
The Dental Sealant Procedure: What to Expect
One of the best things about dental sealants is how simple and comfortable the procedure is. There are no injections, no drilling, and no recovery time. Most patients, including young children, tolerate it very well.
Step-by-Step: How Sealants Are Applied
- Cleaning the tooth surface: The target tooth is thoroughly cleaned to remove any plaque or debris before the sealant is placed.
- Drying and isolating the tooth: The tooth is dried completely and kept dry using absorbent materials. Moisture can prevent the sealant from bonding correctly.
- Applying the etching solution: A mild acidic solution is applied to the chewing surface to slightly roughen the enamel. This creates a better surface for the sealant to adhere to.
- Rinsing and drying again: The etching solution is rinsed off thoroughly and the tooth is dried a second time.
- Painting on the sealant: The liquid sealant material is carefully painted into the grooves and fissures of the chewing surface where it flows in and fills the depressions.
- Curing the sealant: A special curing light hardens the material within seconds, bonding it firmly to the tooth surface.
- Checking the bite: We make a quick check to ensure the sealant does not interfere with your bite and make any minor adjustments if needed.
The entire process typically takes only a few minutes per tooth. Multiple teeth can often be sealed in a single appointment, and the patient can eat and drink normally immediately afterward.
How Long Do Dental Sealants Last?
Sealants are durable and designed to withstand the forces of everyday chewing, but they are not permanent. With proper care, most sealants last between five and ten years before they need to be checked and potentially reapplied.
During every routine dental cleaning, our team checks the condition of existing sealants. We look for chips, wear, or areas where the seal may have lifted, and recommend reapplication where needed. Catching a compromised sealant early and resealing it prevents decay from getting a foothold in the newly exposed groove.
Dental Sealants as Part of a Complete Preventive Strategy
Sealants are most effective when they are one part of a broader oral health routine rather than a standalone solution. They protect chewing surfaces but do not cover the spaces between teeth or the areas along the gumline. A complete prevention strategy combines:
| Preventive Measure | What It Protects |
|---|---|
| Dental Sealants | Chewing surface grooves and pits on back teeth |
| Daily Brushing with Fluoride Toothpaste | All visible tooth surfaces |
| Daily Flossing | Spaces between teeth and below the gumline |
| Professional Cleanings | Tartar removal from all surfaces, including areas missed at home |
| Fluoride Treatments | Overall enamel strength and acid resistance |
| Gum Disease Monitoring | Gum tissue and bone supporting the teeth |

Are Dental Sealants Covered by Insurance?
Many dental insurance plans cover sealants for children up to a certain age, typically through age 14 or 16, as part of their preventive benefits. Coverage for adults varies by plan. Our team is happy to verify your benefits before your appointment and walk you through any out-of-pocket costs. For patients without insurance or those looking to maximize value, we encourage you to review our new patient specials and discuss payment options with our front desk.
From a financial standpoint, sealants are one of the best investments in preventive dental care available. The cost of placing a sealant is a fraction of the cost of a filling, a crown, or any other restorative treatment required once decay is present. Preventing the problem entirely is always the smarter and more affordable path.

Frequently Asked Questions About Dental Sealants in Glendale, AZ
Do dental sealants hurt?
No. The procedure involves no drilling, no injections, and no discomfort. Most patients describe it as entirely uneventful. Children and anxious patients tolerate it very well because nothing about the process is invasive or uncomfortable.
How long does it take to apply dental sealants?
Each tooth takes only a few minutes from start to finish. Multiple teeth are often sealed in a single appointment. Most patients are in and out quickly, with no restrictions afterward on eating or drinking.
At what age should my child get dental sealants?
We typically recommend sealants around age six when the first permanent molars erupt, and again around age twelve for the second permanent molars. Applying them as soon as the teeth are fully accessible gives them the best chance to protect those surfaces throughout childhood. Learn more on our child dentistry page.
Can adults get dental sealants?
Yes. Adults with deep molar grooves that are free of decay and existing fillings are excellent candidates. There is no age restriction, and the procedure is just as effective for adults as it is for children.
How long do dental sealants last?
Most sealants last five to ten years. We check them at every cleaning appointment and reapply them if wear or chipping is detected. Catching a failing sealant early prevents decay from developing in the newly exposed groove.
Can a cavity form under a dental sealant?
A properly applied sealant on a cavity-free tooth will not allow decay to develop underneath it. However, if a sealant is placed over a tooth that already has early-stage decay, or if the sealant chips and is not repaired promptly, bacteria can reach the tooth surface. This is why regular checkups are important to monitor sealant integrity.
Do sealants replace brushing and flossing?
No. Sealants protect the chewing surfaces of back teeth but do not cover the spaces between teeth or areas near the gumline. Daily brushing and flossing remain essential. For guidance, see our oral hygiene page.
