Protect Growing Smiles with Dental Sealants in Glendora, CA

At Little Grins Pediatric Dentistry, prevention is at the heart of everything we do — and one of the easiest, most effective ways to protect your child’s teeth from cavities is with dental sealants.


Our pediatric dentists in Glendora, CA use BPA-free sealants to safeguard little smiles from decay. This simple, painless treatment provides long-lasting protection for the teeth most at risk — helping your child stay cavity-free and confident about their smile.


What Are Dental Sealants?


Sealants are thin, protective coatings applied to the chewing surfaces of the back teeth (molars and premolars), where most cavities form. Even with regular brushing and flossing, it can be difficult for kids to clean every groove in their molars — and that’s where bacteria love to hide.


Sealants act like a shield, sealing out food particles, acids, and bacteria that can lead to cavities. Once applied, they create a smooth surface that makes brushing easier and more effective.


Why Sealants Matter for Kids


Children are especially prone to cavities as they learn to brush independently and develop good dental habits. Sealants offer a simple, preventive solution that can last for years, reducing the risk of decay during the most cavity-prone stages of childhood.


Studies show that sealants can reduce cavities by up to 80% in molars — the most common site for decay. That means fewer fillings, less dental work, and a happier, healthier smile for your child.


Our BPA-Free Sealant Process


At Little Grins Pediatric Dentistry, we use 100% BPA-free sealants that are safe, durable, and perfectly suited for children. The process is quick, comfortable, and needle-free:


Cleaning the Tooth: We gently clean and dry the tooth to prepare for application.


Applying the Sealant: The sealant material is brushed onto the chewing surface.


Curing with Light: A special blue light hardens the sealant in seconds.


Instant Protection: Your child can eat, drink, and smile right after the appointment!


Most children receive sealants on their first and second permanent molars around ages 6 and 12 — but your pediatric dentist will recommend the best timing based on your child’s needs.


Benefits of Dental Sealants


Completely Painless: No drilling, numbing, or discomfort — just simple, gentle protection.


Long-Lasting: Sealants can last several years with proper care.


Safe and Effective: Made from BPA-free materials that are safe for children.


Saves Time and Money: Prevents cavities before they start, reducing future dental costs.


Perfect for Busy Families: The application takes only a few minutes per tooth!

What Our Families Are Saying!

Need Help? 

Frequently asked questions 

  • What age should my child first visit the dentist?

    The American Academy of Pediatric Dentistry recommends a child’s first dental visit by age one or within 6 months of the first tooth appearing. Early visits help us monitor development and create positive, stress-free experiences from the start.

  • What makes Little Grins different from other pediatric dental offices?

    Our office is completely designed around children — with themed rooms, TVs on the ceiling, sensory boards, a prize wall, and gentle, kid-focused care. We combine advanced technology with compassion to provide safe, fun, and comfortable visits for every child.

  • Do you accept dental insurance?

    Yes! We accept most PPO insurance plans and help families verify benefits. We also file claims on your behalf to make the process simple and stress-free.

  • What if my child is anxious or afraid of the dentist?

    We specialize in helping nervous or fearful children feel relaxed. Our team uses kid-friendly language, distraction techniques, and positive reinforcement. We also offer nitrous oxide (laughing gas) and other sedation options for extra comfort.

  • Do you offer sedation dentistry?

    Yes. For children who need additional support, we offer nitrous oxide, oral conscious sedation, and general anesthesia, depending on your child’s needs and the procedure.

  • Are your X-rays safe for children?

    Absolutely. We use low-radiation digital X-rays and a portable NOMAD system to keep radiation levels extremely low while still providing clear, accurate images.

  • What should I do if my child has a dental emergency?

    Call us right away at (626) 788-3308. We offer same-day emergency appointments for issues such as chipped teeth, toothaches, knocked-out teeth, swelling, or pain.

  • Do you treat children with special healthcare needs?

    Yes — our pediatric dentists have extensive training in caring for children with developmental, behavioral, and medical needs. We offer patient, individualized care in a calm, supportive environment.

  • What are BPA-free fillings, and why do you use them?

    BPA-free fillings are tooth-colored, biocompatible materials that restore teeth safely and naturally. We use them because they blend beautifully with your child’s smile and avoid the health concerns associated with BPA.

  • How can I help my child prevent cavities at home?

    Brush twice daily with fluoride toothpaste, floss once per day, avoid frequent snacking and sugary drinks, and maintain regular checkups every six months. We also recommend dental sealants and fluoride treatments to provide extra protection.
