Kids Dental Fillings in Oakland, CA

Montclair Pediatric Dentistry is a boutique pediatric practice that offers tooth fillings for kids in Oakland, CA. Founded by board-certified pediatric dentists Dr. Lina Paek and Dr. Rebecca Hsieh, the practice draws on 20 years of their combined clinical experience. 

When your child has a cavity, our team uses tooth-colored composite fillings that blend naturally with their teeth and stop decay from spreading.

  • Blends naturally with your child’s tooth color
  • Preserves more healthy tooth structure than older filling types
  • Usually done in one comfortable visit

Does My Child Have a Cavity?

A few signs are worth mentioning at your child’s next visit, or sooner if they’re bothering your child:

  • A visible dark spot or discoloration on a tooth
  • Sensitivity to sweets, or to hot and cold foods and drinks
  • Complaining when chewing on one side

Not every cavity causes obvious symptoms though, which is one more reason regular exams matter even when nothing seems wrong.

The Benefits of Tooth-Colored Fillings

Here’s what a tooth-colored filling actually does for your child’s tooth.

Natural Appearance

Composite fillings match your child’s natural tooth color, blending in rather than standing out.

Strong Protection

The filling material seals out bacteria and prevents further decay while strengthening the surrounding tooth.

Minimal Removal

Composite fillings preserve more of your child’s healthy tooth structure compared to older filling types, since less needs to be removed to place them.

Long-Lasting Results

A properly placed filling protects your child’s tooth through years of normal eating and brushing.

About Dental Fillings

Tooth-colored composite fillings bond directly to your child’s tooth, creating a strong seal that prevents bacteria from causing further decay. The process is comfortable and efficient. Our pediatric dentists gently remove the decayed portion of the tooth, carefully preserving as much healthy tooth structure as possible. We then place the tooth-colored filling material, shape it to match your child’s natural tooth contours, and harden it with a special light. The result is a restored tooth that looks and functions naturally.

Most fillings take about 20 to 45 minutes per tooth, depending on the cavity size. We numb the area with a topical gel before any injection, so your child feels pressure rather than a sharp pinch. Unlike metal fillings, composite sets right away, so your child can eat normally as soon as the numbness wears off.

about dental fillings

Why We Use Tooth-Colored Fillings, Not Metal

Montclair Pediatric Dentistry doesn’t use metal amalgam fillings, so none of our fillings contain mercury. Every filling we place is tooth-colored. For most cavities, that means composite resin. Composite bonds directly to the tooth and is shaped to match its natural contours.

For some cavities, we use a glass ionomer material instead, such as EQUIA Forte or GC Fuji. These are also tooth-colored, and they release fluoride over time, which helps reduce the risk of new decay forming around the filling.

Why Choose Montclair for Dental Fillings

Dr. Paek and Dr. Hsieh are board-certified by the American Board of Pediatric Dentistry, and we place every filling with materials chosen specifically for kids. Our composite resin is BPA-free, which matters to many parents beyond the tooth-colored appearance.

We also know cavities can cause real anxiety for both kids and parents. We’ll walk you through what we’re doing at each step, in language your child can actually follow.

My husband and I, and most importantly our 2 year old son, absolutely loved our first experience at the Montclair Pediatric Dentistry, or any dentist for that matter. Dr. Rebecca and her team were incredibly friendly, warm and thoughtful. We were greeted with a personalized welcome sign and an abundance of toys and games for various ages as well as other fun distractions to keep our son occupied while being examined. Dr. Rebecca truly has an amazing way with children and made our son feel very comfortable with her at all times during the appointment – even when she was flossing his teeth! We are thrilled with the services and would not hesitate to recommend Dr. Rebecca and the Montclair Pediatric Dentistry to our friends and family (which we already have!).

I can't say enough wonderful things about Montclair Pediatric Dentistry! Recently, my daughter had a little mishap and bumped her front teeth. In a moment of panic, I reached out to Dr. Lina's office, and Evelyn at the front desk was incredibly accommodating in getting us in for an appointment right away. From the moment we arrived, Dr. Lina's warm and welcoming demeanor put my daughter at ease. She took the time to thoroughly examine her teeth and was exceptionally informative about what to expect in terms of healing. ... What truly stood out was Dr. Lina's gentle approach. You can genuinely see her passion for pediatric dentistry; she connects with her young patients in a way that makes them feel safe and cared for. ... I am so grateful for the exceptional service we received and will definitely be bringing my other children to Montclair Pediatric Dentistry. I highly recommend Dr. Lina and her team to all my friends and family.

We had a great experience here. We've tried several different pediatric dentists over the years and feel so lucky to have found Montclair Pediatric Dentists! Everyone in the office was warm and helpful. Their office is new, clean, kid-friendly and beautiful. Before we even started, Dr. Lina noticed a food allergy in my daughter's health history and she provided the ingredient list of the materials they use, ensuring safety. The dental hygienist, Viridiana, and Dr. Lina did the most careful and extensive cleaning compared to my daughter's past dentists. They were gentle and explained the process thoroughly. ... Even with a one hour commute, my daughter loved her visit and is happy to go back!

Took my kids to Montclair Pediatric Dentistry this morning and it was a great experience. Dr. Lina was kind, thorough and engaging with my children. The office staff were super friendly, knowledgeable, and welcoming. The office just opened up in June and it's a really beautiful designed space...I appreciate all the details that make the uneasy experience of going to the dentist very pleasant. Thankful that our other dentist fell out of our insurance network and that we get to have an even better dentist now!

We love Montclair Pediatric Dentistry. We switched here due to an insurance change and were nervous about how our 7 year old would handle it. But they've gone from absolutely dreading the experience to telling us - unprompted - how much they love Dr. Lina and the new office. So happy we're here.

I visited this location and I gotta say my son and I had an A+ experience at Montclair Pediatric Dentistry during our recent visit with Dr. Hsieh. The team was warm, welcoming and understood my son's dental needs. Dr. Hsieh has a kind and gentle way with kids, making dental visits a fun and positive experience. My son left with a big smile and a newfound excitement about brushing his teeth. Highly recommend Montclair for anyone looking for a caring and professional pediatric dentist!

Bryan Lin

My four year old son had his first appointment today with Montclair Pediatric after deciding to switch from his former office and we were super happy with everything. The waiting area is so intentional and thoughtful with Montessori type toys that encourage learning, tons of sweet books (including some about going to the dentist to help the nervous kiddos) and even coffee for the adults. Dr. Rebecca was very sweet and my son actually enjoyed his visit. The office is clean, calm, fun and inviting. Happy to have found our new pediatric dental office.

Dr. Lina is the best! We had a great experience at her new office. My kids had previously seen Dr. Lina at a different location, and they wanted to continue seeing her as their dentist. It is challenging to find a pediatric dentist that is a good match for my kids, so we were more than happy to follow her to her new location. ... I appreciate Dr. Lina's swift hand skills, her comprehensive approach towards treatments and prevention, and her ability to communicate effectively with both kids and parents. I also appreciate Dr. Lina's efforts to preserve the natural tooth as much as possible, with a focus on prevention and long-term health. ... Also, her office is beautiful and welcoming! My kids really enjoyed their visit. I cannot recommend Dr. Lina enough!

Other Treatments That May Fit Your Child's Needs

A couple of other services may be worth knowing about depending on how a cavity is treated.

Dental Crowns

When a tooth needs more protection than a filling can provide, a crown is often the next step.

Dental Sealants

A protective coating that can help prevent new cavities from forming on other teeth.

Frequently Asked Questions

How long do dental fillings last?

With proper care, composite fillings can last for years, often until a baby tooth naturally falls out or well into adulthood for permanent teeth. Regular check-ups help us catch any wear early.

Is getting a filling painful?

No, we numb the area first, so your child shouldn’t feel pain during the procedure. Most kids report feeling pressure at most, not pain.

Why choose tooth-colored fillings over silver ones?

Tooth-colored fillings blend in, require less removal of healthy tooth structure, and bond directly to the tooth for added strength. They also don’t contain the mercury found in metal amalgam fillings, which we don’t use.

How should we care for a new filling?

Your child can eat normally once the numbness wears off. Regular brushing and flossing help the filling last and prevent new cavities from forming.
