The End of Dark, Noticeable Fillings
Cavities and small fractures can cause much larger issues if left untreated. In the past, metal restorations called amalgam fillings, or silver fillings, served a need but left many teeth discolored and structurally strained from the wedging effect of the metal expanding and contracting over time. Today, tooth-colored composite resins blend seamlessly into the tooth structure and are chemically bonded to the tooth, providing a strong, permanent restoration that looks and feels completely natural.
Composites serve both functional and aesthetic roles, often at the same time. For example, a cavity invading the front of a tooth along the gum line may be visible in your smile line. By gently cleaning out the soft, discolored area and replacing it with a tooth-colored filling, the tooth is restored and looks better than ever.

Why Composite Is the Better Choice
Many patients who come to us still have old silver amalgam fillings that were placed years or even decades ago. Here is why composite resin is the superior choice, for new fillings and as a replacement for old metal restorations:
- Natural Appearance - Composite fillings are color-matched to your teeth, while amalgam fillings are dark and highly visible.
- More Tooth Preservation - Composite bonds directly to the tooth, allowing for a smaller, more conservative preparation.
- Better Long-Term Protection - Unlike metal fillings, composite does not expand and contract with temperature changes that can stress the tooth.
- Mercury-Free Material - Composite fillings contain no mercury and are safe for patients of all ages.
- Strong, Secure Bond - Composite resin chemically bonds to the tooth for a durable, integrated restoration.
What Happens During a Composite Filling Appointment
Getting a composite filling at our Newark office is a straightforward, comfortable procedure that is typically completed in a single appointment:
Step 1 — Anesthesia
Local anesthesia is administered to fully numb the tooth and surrounding area. We use topical anesthetic before any injection to minimize discomfort. We always confirm the area is completely numb before proceeding.
Step 2 — Decay Removal
The decayed or damaged portion of the tooth is gently and precisely removed, taking only what needs to come out and preserving as much healthy tooth structure as possible.
Step 3 — Tooth Preparation
The prepared cavity is cleaned, conditioned, and primed to create the ideal surface for the composite resin to bond to chemically and securely.
Step 4 — Composite Placement
The tooth-colored composite resin is carefully selected to match your natural tooth shade and applied to the prepared cavity in layers, each layer shaped and molded precisely to restore the tooth's natural contours.
Step 5 — Curing with Blue Light
Each layer of composite is hardened within seconds using a blue curing light applied directly to the resin. This light-activated process creates an immediate, strong bond between the composite and the tooth structure.
Step 6 — Shaping & Polishing
Once the composite is fully placed and cured, our doctors shape and refine the restoration, checking your bite carefully and making any adjustments needed. A final polish brings the composite to a natural high shine that closely mimics the surface of your surrounding tooth enamel.
The entire process typically takes between 30 and 60 minutes per tooth depending on the size and location of the cavity.
Ready to Replace Your Old Silver Fillings in Newark, CA?
Many of our patients choose to have their existing amalgam fillings replaced with tooth-colored composite restorations, for both cosmetic and structural reasons. Old metal fillings that are showing signs of wear, cracking, leaking, or discoloration are particularly good candidates for replacement.
If you have old silver fillings that you are unhappy with or that your dentist has identified as failing, composite fillings offer a natural-looking, structurally sound alternative that will serve you well for many years.
Our doctors will assess each existing filling individually and give you an honest recommendation about whether replacement is clinically indicated or purely a cosmetic preference. We will never recommend replacing a filling simply to generate treatment, only when it genuinely serves your health and smile.
