Dental Sealants: Minimally Invasive Protection Against Tooth Decay

Q: What Are Dental Sealants?

Dental sealants are thin, protective coatings painted onto the chewing surfaces of back teeth (molars and premolars). These tooth-colored resin or glass materials bond directly to tooth enamel. Once applied, a curing light hardens the sealant into a durable shield over each tooth's grooves. This creates a nearly invisible barrier that "seals out" food particles and cavity-causing bacteria. By coating the deep pits and fissures that easily trap plaque, sealants prevent decay on the chewing surfaces that brushing and flossing alone often miss.

Q: Who Can Benefit from Sealants?

Children and teens: The most common candidates are kids and adolescents. Sealants are ideal soon after permanent molars erupt (around ages 6 and 12). Applying sealants during these cavity-prone years helps protect teeth through childhood. School programs and dentists often recommend sealants for children as a routine preventive measure. Adults at risk: Adults without decay or restorations on their back teeth can also benefit. Even grown-ups with healthy premolars or molars that have deep grooves should consider sealants as a preventive step. High-risk patients: Patients of any age who are prone to cavities (due to factors like dry mouth, braces, or sugar intake) are great candidates for sealants. In short, anyone with clean, intact teeth and deep chewing-surface grooves may find sealants helpful.

At Prestige Dental Pasadena, our Pasadena dentists, Dr. Bouzoghlanian and Dr. Doudian, emphasize preventive care. In addition to offering advanced cosmetic dentistry in Pasadena, our dentists recommend dental sealants—a thin, plastic-like coating that guards the deep grooves of molars and premolars. Sealants act as a minimally invasive protection against cavities by filling pits and fissures that brushing alone can miss. Applied at our Pasadena dental office with no drilling or anesthesia, sealants provide years of decay prevention in a quick, painless step.

Benefits of Sealants

Blocks decay: Sealants "cover" vulnerable grooves, preventing tooth decay in those spots. Studies show that sealants can prevent up to 80% of cavities for two years (and 50% for up to four years) when applied early.
Minimally invasive and painless: The application requires no drilling or anesthesia. The process is simple – just cleaning, drying, and painting on the sealant – so it's entirely painless and quick.
Cost-effective: Preventing cavities is far less expensive than treating them later. A one-time sealant application spares families the hassle, discomfort, and cost of future fillings or root canals.
Long-lasting protection: Sealants typically last 3–5 years (often longer with good care). At check-ups, our dentist in Pasadena will inspect and repair or replace sealants as needed to maintain protection.
Stop early decay: Sealants cover tiny pits, halting early, non-cavitated decay by cutting off bacterial access. This makes sealants an excellent complement to fluoride and brushing in a comprehensive oral health plan.

How Are Sealants Placed?

Application of dental sealants at Prestige Dental Pasadena is non-invasive and straightforward. Here are the typical steps our dentists, Dr. Bouzoghlanian and Dr. Doudian, in Pasadena, will follow:

Clean the tooth: Effectively cleans the targeted teeth, eliminating plaque and debris with precision.
Isolate and dry: The teeth are kept completely dry (often with cotton rolls or a cheek retractor) so the sealant will bond properly.
Etch the enamel: A mild acidic gel is painted on the tooth surface. This "etches" or microscopically roughens the enamel, creating a surface that the sealant can adhere to.
Rinse and dry again: After a short time, the etching solution is rinsed off, and the tooth is dried again.
Apply the sealant: The liquid sealant material is carefully painted into the grooves of the tooth. It flows easily into pits and fissures.
Cure with light: A special blue curing light is then used to harden the sealant. Within seconds, the liquid resin hardens into a strong, protective coating.

After placement, you can eat and drink normally right away (though our dentist in Pasadena, Dr. Bouzoghlanian, often recommends avoiding hard or sticky foods for a day). The entire procedure takes only a few minutes per tooth and requires no shots or drilling.

Maintenance and Limitations

While highly effective, dental sealants are not permanent. With regular wear, they usually last several years (typically 3–5 years). During your regular checkups at Prestige Dental Pasadena, our dentists in Pasadena will inspect the sealants. If any sealant is chipped or worn, it can be easily repaired or reapplied to restore complete protection. Remember:

Stay vigilant: Sealants only cover the biting surfaces. They don’t protect between teeth or replace good oral hygiene. You should still brush twice daily with fluoride toothpaste and floss every day.
Check-ups: Continue routine exams and cleanings. This allows your dentist to monitor the sealant condition and the overall health of your teeth and gums.
When they can't be used: Sealants are applied to healthy teeth. If a tooth already has a cavity or filling, that area will need restorative treatment instead.

Are Sealants Safe?

Yes. Dental sealants are made from biocompatible, medical-grade resins or glass-ionomer materials. They are BPA-free or contain only trace, clinically insignificant BPA levels. The American Dental Association notes that the amount of BPA exposure from sealants is extremely low and not considered a health risk. In fact, the tiny BPA traces (if any) dissipate quickly. In summary, sealants are a safe and proven preventive measure.
