For many decades, dentists used silver amalgam fillings to repair teeth that had cavities. While this material is effective at filling in a tooth to restore its structure after decay, its silver color is very visible within the smile and some patients have concerns about the mercury content in amalgam. At Shadowridge Dental Group, we are committed to offering our patients in the San Marcos, Oceanside, Carlsbad, Escondido, Encinitas, and neighboring CA areas options when it comes to their dental care, including tooth-colored composite fillings.
Benefits of tooth-colored fillings
Tooth-colored fillings are made from a material called composite resin, which is a durable and versatile material that can be used on both the front and back teeth. White cavity fillings have many benefits:

- They are discreet and blend in with your natural tooth structure so they don’t affect the appearance of your smile
- The composite resin material expands and contracts in a similar manner to your natural teeth, making it less prone to cause fractures or other damage to the surrounding tooth structure
- Unlike amalgam, composite resin bonds to the enamel of the tooth for durable results; in addition, this means a smaller amount of your natural tooth needs to be removed to place a composite filling, making it a more conservative treatment option
The cavity filling process
When you have a cavity in your tooth, it is a small area of decay that has compromised the tooth structure and needs to be removed so that the bacteria don’t infiltrate further into the tooth. When you come in for a filling, we first numb the area thoroughly with a local anesthetic so you are comfortable and pain-free throughout the procedure. Then, we gently remove the decayed area with specialized dental tools and sanitize it before starting to fill it with the composite resin. The material is placed on your tooth one layer at a time, and we cure it layer by layer for a strong and durable finish. Finally, we shape the filling as needed so it feels like your normal tooth and does not impact how your teeth bite together.
Composite Fillings FAQs
What are composite fillings?
Composite fillings are tooth-colored restorations made from a blend of resin and fine glass particles. They are used to repair cavities, chips, and minor wear. The material bonds directly to the tooth, restoring shape and strength while matching the natural color of surrounding enamel for a discreet appearance. They can also be used to reshape teeth and close small gaps, offering a cosmetic benefit in addition to repair.
Why choose composite fillings instead of metal (amalgam) fillings?
Many patients prefer composites because they look natural and avoid visible metal in the mouth. Unlike amalgam, composites bond to tooth structure, allowing the dentist to preserve more healthy enamel during treatment. Composites are also less prone to expanding and contracting with temperature changes, which can reduce the risk of future cracks.
Who is a good candidate for composite fillings?
Most people with small to moderate cavities are good candidates. Composite is especially appropriate for front teeth and other visible areas where appearance matters. For very large cavities, back teeth under heavy chewing forces, or teeth with extensive structural damage, we recommend alternatives such as inlays, onlays, or crowns. A careful exam, including X-rays, helps us choose the most durable option for each tooth.
How long do composite fillings last?
With proper care, composite fillings typically last 7 – 10 years. Longevity depends on factors like the filling size, the tooth’s location, oral hygiene habits, and whether the patient grinds their teeth. Regular dental exams help detect wear early, allowing timely repairs or replacements.
What can I expect during the filling procedure?
The procedure usually takes less than an hour per tooth. First, we numb the area and remove decay. The tooth is then cleaned and isolated, and the composite resin is placed in layers. Each layer is hardened with a curing light, then shaped and polished for a smooth, natural finish. Most patients experience only mild sensitivity for a few days. Local anesthesia and gentle techniques keep the experience comfortable, and most patients resume normal activities immediately.
Does dental insurance cover composite fillings?
Many insurance plans provide coverage for composite fillings, especially when they are used to restore tooth function. Coverage varies by policy; some plans reimburse up to the cost of amalgam for back teeth and require patients to pay the difference. Our front-desk team will review your benefits and provide an estimate before treatment.
How much do composite fillings cost at Shadowridge Dental Group?
Cost depends on the tooth involved and the complexity of the restoration. Small fillings are generally less expensive than larger, multi-surface restorations. Shadowridge Dental Group offers transparent pricing and can discuss payment options or financing to make treatment affordable. We provide a written treatment plan detailing fees and can recommend options to fit most budgets.
Are composite fillings safe?
Yes. Composite materials used today are biocompatible and free from mercury. They are a widely accepted restorative option and are considered safe for most patients. If you have specific material concerns or allergies, discuss them so the team can select the best restorative option.
How should I care for my composite filling to make it last?
Care is the same as for natural teeth: brush twice daily with fluoride toothpaste, floss daily, and keep regular dental checkups. Avoid chewing on ice, hard candy, or non-food items, and consider a nightguard if you grind your teeth. Early attention to any sensitivity or chipping helps extend the life of the restoration.
