The Truth About BPA in Dental Fillings and Sealants
If you’re a health-conscious resident of Encino, Tarzana, Sherman Oaks, or anywhere in the San Fernando Valley, you’ve probably heard about BPA and made efforts to avoid it in water bottles, food containers, and baby products. But did you know that BPA can also be found in some dental materials? As more Californians seek to minimize their exposure to potentially harmful chemicals, understanding BPA in dentistry—and how to avoid it—has become increasingly important.
At Encino Holistic Dentistry, Dr. Linda Makuta is committed to using biocompatible, BPA-free materials that support your overall health. Let’s explore what BPA is, where it’s found in dental treatments, the science behind the concerns, and most importantly, what BPA-free alternatives are available for Los Angeles area patients.
What Is BPA and Why Should You Care?
BPA, or bisphenol A, is a synthetic chemical that’s been used since the 1960s to make certain plastics and resins. It’s found in polycarbonate plastics (hard, clear plastics) and epoxy resins (used to coat the inside of metal products like food cans and bottle tops).
The Health Concerns
BPA is what’s called an “endocrine disruptor,” meaning it can interfere with your body’s hormone system. Research has raised concerns about BPA’s potential effects on:
- Reproductive health: BPA may affect fertility and fetal development
- Brain development: Studies suggest possible impacts on behavior and brain development in fetuses, infants, and children
- Cardiovascular health: Some research links BPA exposure to increased blood pressure and heart disease risk
- Metabolic function: BPA may contribute to obesity and diabetes
- Immune system: Potential effects on immune function
- Cancer risk: Some studies suggest possible links to certain cancers
California’s Stance on BPA
California has been a leader in regulating BPA. The state was one of the first to ban BPA in baby bottles and sippy cups, and has listed BPA as a chemical known to the state to cause reproductive harm under Proposition 65. Many California cities, including some in Los Angeles County, have enacted additional BPA restrictions. This progressive stance reflects growing concern about chemical exposure and aligns with the health-conscious values of many San Fernando Valley residents.
BPA in Dental Materials: Where It’s Found
The primary dental materials that may contain or release BPA are composite resins used for tooth-colored fillings and dental sealants. Here’s what you need to know:
Composite Resin Fillings
Many composite resins contain bis-GMA (bisphenol A-glycidyl methacrylate) and bis-DMA (bisphenol A dimethacrylate), which are derivatives of BPA. These materials don’t technically “contain” BPA in its pure form, but they can break down and release small amounts of BPA, particularly:
- During the curing process (when the filling is hardened with a special light)
- When the filling is being polished
- During the first 24-72 hours after placement
- When composite materials wear down over time
Dental Sealants
Dental sealants—thin plastic coatings applied to the chewing surfaces of back teeth to prevent cavities—may also contain bis-GMA and potentially release BPA. This is particularly concerning for parents in the Los Angeles area considering sealants for their children.
Other Dental Materials
BPA or its derivatives may also be found in:
- Some dental cements
- Certain bonding agents
- Some temporary crown materials
- Orthodontic materials
The Science: How Much BPA Are We Really Talking About?
Understanding the Research
It’s important to put BPA exposure from dental materials into perspective. Research shows:
The exposure is generally small: Studies have found that BPA levels from dental composites are typically much lower than exposure from dietary sources (like canned foods or thermal receipts). Most detectable BPA appears within the first few hours after placement and decreases rapidly.
Proper technique matters: Studies show that thorough polishing and rinsing after placing composite fillings significantly reduces BPA release. The curing process, when done properly, also minimizes residual monomers that could break down into BPA.
Individual variation exists: Some people may be more sensitive to even small amounts of BPA, particularly those with chemical sensitivities, autoimmune conditions, or compromised detoxification systems.
The precautionary principle: While the exposure from dental materials is relatively small, many health-conscious patients—especially in areas like Encino where wellness is a priority—prefer to minimize all unnecessary chemical exposures, particularly for children and pregnant women.
Who Should Be Most Concerned?
Certain groups may want to be particularly careful about BPA exposure from dental materials:
- Pregnant women: BPA can cross the placental barrier
- Nursing mothers: BPA can appear in breast milk
- Infants and young children: Developing systems are more vulnerable to endocrine disruptors
- Individuals with hormone-sensitive conditions: Such as certain cancers or endocrine disorders
- People with chemical sensitivities: May react to even small exposures
- Those with compromised detoxification: Liver or kidney issues may affect BPA processing
BPA-Free Alternatives: Your Options
The good news is that advances in dental materials have given us excellent BPA-free alternatives. At Encino Holistic Dentistry, we prioritize these options for all our San Fernando Valley patients:
1. BPA-Free Composite Resins
Several manufacturers now produce composite resins that don’t contain bis-GMA, bis-DMA, or other BPA derivatives. These modern materials use alternative resin systems that provide excellent durability and aesthetics without BPA concerns.
Benefits:
- Completely free of BPA and its derivatives
- Excellent aesthetic results—tooth-colored and natural-looking
- Comparable durability to traditional composites
- Bonds well to tooth structure
- Suitable for both front and back teeth
Examples of BPA-free resin systems:
- Composites using UDMA (urethane dimethacrylate) instead of bis-GMA
- Ormocer-based composites (organically modified ceramics)
- Silorane-based composites
Best for: Patients of all ages seeking tooth-colored restorations without BPA exposure, particularly pregnant women, children, and those with chemical sensitivities
2. Glass Ionomer Cement
Glass ionomer is a completely BPA-free material made from acrylic acids and fine glass powders. It’s been used safely in dentistry for decades.
Benefits:
- Absolutely no BPA or BPA derivatives
- Releases fluoride, which can help prevent future decay
- Bonds chemically to tooth structure
- Biocompatible and well-tolerated
- Good for children’s teeth and certain adult applications
Considerations:
- Less durable than composite for high-stress areas
- Not as aesthetic as composite (more opaque)
- Best for specific applications rather than all situations
Best for: Children’s teeth, root surface cavities, areas below the gum line, patients at high risk for decay, temporary restorations
3. Ceramic (Porcelain) Restorations
Ceramic inlays, onlays, and crowns are made entirely from dental ceramic—a material that contains no BPA, plastics, or resins whatsoever.
Benefits:
- Completely BPA-free and biocompatible
- Superior aesthetics—can be virtually indistinguishable from natural teeth
- Extremely durable and long-lasting

- Best for larger restorations
Best for: Larger cavities, replacing old fillings, patients seeking the most biocompatible and aesthetic option, those with multiple chemical sensitivities
4. Gold Restorations
Gold inlays, onlays, and crowns contain no BPA, plastics, or resins. While not as popular in aesthetic-conscious Los Angeles, they remain an excellent BPA-free option.
Benefits:
- Completely BPA-free
- Extremely durable (can last 20-30+ years)
- Biocompatible and well-tolerated
- Time-tested material with excellent track record
Considerations:
- Highly visible—not tooth-colored
- Most expensive option
- May not align with aesthetic preferences of most San Fernando Valley patients
Best for: Back teeth in patients who prioritize durability and biocompatibility over aesthetics
What About Dental Sealants for Children?
Many parents in Encino and throughout the San Fernando Valley ask about BPA in dental sealants for their children. This is an important consideration, as sealants are often recommended for children and teenagers to prevent cavities.
BPA-Free Sealant Options
At Encino Holistic Dentistry, we offer BPA-free sealant materials for children. These include:
- Glass ionomer sealants: Completely BPA-free and release fluoride
- BPA-free resin sealants: Newer formulations without bis-GMA or bis-DMA
Weighing the Benefits and Risks
Even with traditional sealants, research suggests the cavity prevention benefits typically outweigh the minimal BPA exposure. However, with BPA-free alternatives now available, parents don’t have to make that choice. You can protect your child’s teeth from cavities while also minimizing chemical exposure.
Our Recommendation for San Fernando Valley Families
We recommend BPA-free sealants for all children, particularly:
- Girls approaching puberty (when hormone sensitivity may be higher)
- Children with existing health conditions
- Families already taking steps to minimize BPA exposure in other areas
- Any child whose parents prefer to avoid unnecessary chemical exposures
Minimizing BPA Exposure from Dental Procedures
Even if you choose traditional composite materials (which may contain BPA derivatives), there are steps that can minimize your exposure:
During the Procedure
- Proper isolation: Using a rubber dam keeps materials away from your mouth and throat during placement
- Adequate curing: Properly hardening the material reduces residual monomers that could break down
- Thorough polishing: Removing the oxygen-inhibited layer (surface layer that doesn’t fully cure) significantly reduces BPA release
- Extensive rinsing: Rinsing thoroughly after placement removes any unreacted material
After the Procedure
- Avoid eating for 1-2 hours: This gives the material time to fully set
- Rinse frequently: For the first 24 hours, rinse your mouth with water after meals
- Avoid alcohol-based mouthwashes: For the first few days, as alcohol can break down composite materials
- Support detoxification: Stay well-hydrated and eat a nutrient-rich diet to support your body’s natural detoxification processes
Questions to Ask Your Dentist
If you’re concerned about BPA in dental materials, don’t hesitate to ask your dentist:
- Do you use BPA-free composite materials?
- What specific brands or types of materials do you use?
- Can you provide me with information about the materials before my procedure?
- Do you offer BPA-free sealants for children?
- What techniques do you use to minimize any BPA exposure?
- Do you offer biocompatibility testing for patients with sensitivities?
- What are my alternatives if I want to completely avoid any materials with BPA derivatives?
The Bigger Picture: Biocompatibility and Individual Chemistry
At Encino Holistic Dentistry, our approach goes beyond simply avoiding BPA. We recognize that every person’s body chemistry is unique, and what works well for one patient may not be ideal for another.
Biocompatibility Testing
For patients with chemical sensitivities, autoimmune conditions, or those who simply want to be certain they’re using the most compatible materials, we can arrange biocompatibility testing. This blood test analyzes your immune system’s reaction to various dental materials, helping us select the options your body will tolerate best.
This personalized approach is particularly valuable for:
- Patients with multiple chemical sensitivities (MCS)
- Those with autoimmune conditions
- Individuals who have had adverse reactions to dental work in the past
- Anyone undergoing extensive dental treatment
- Health-conscious patients who want the most compatible materials
The Cost of BPA-Free Dentistry
Many patients in the San Fernando Valley wonder if choosing BPA-free materials will significantly increase their dental costs. The good news:
- BPA-free composites: Often cost the same as traditional composites—there’s typically no additional charge
- Glass ionomer: Usually comparable in cost to composite, sometimes less expensive
- Ceramic restorations: More expensive than direct fillings, but this is due to the laboratory fabrication process, not the BPA-free nature
- BPA-free sealants: Typically the same cost as traditional sealants
You can use any dental insurance plan you have, and we’ll provide detailed documentation for you to submit claims directly to your insurance company. We also offer flexible payment plans through CareCredit to make BPA-free dentistry accessible.
California’s Health-Conscious Approach to Dentistry
Los Angeles and the San Fernando Valley have long been at the forefront of health and wellness trends. From the farm-to-table movement to the popularity of yoga and organic living, California residents are increasingly mindful of what they put in and on their bodies.
This consciousness naturally extends to dental care. Patients in Encino, Tarzana, Sherman Oaks, and throughout the area are asking more questions about dental materials, seeking dentists who share their health values, and making informed choices about their oral care.
The availability of BPA-free dental materials means you don’t have to choose between healthy teeth and a healthy body. You can have both.
