Natural looking dental restorations
White composite fillings have replaced old-fashioned silver amalgam as the preferred restorative material at Roam Dental in Shelby Township. Tooth-colored fillings blend seamlessly with your natural enamel, require less drilling, and bond directly to the tooth structure — making them both a healthier and more attractive solution for treating cavities and minor tooth damage.

Tooth-colored fillings are made from composite resin — a mixture of plastic and fine glass particles that can be precisely color-matched to your natural tooth shade. Unlike silver amalgam, composite resin is virtually invisible once placed, making white fillings the clear choice for any tooth that shows when you smile, speak, or laugh.
One of the most significant advantages of composite resin is that it bonds chemically and mechanically to the tooth structure itself. This bonding means Dr. Barbu can preserve more of the healthy tooth — less drilling is required compared to the undercut preparations needed to retain traditional amalgam fillings. The result is a stronger tooth with a smaller restoration footprint. Regular dental cleanings help detect cavities early when smaller fillings are possible.
Composite resin is also completely mercury-free, addressing the concern many patients have about the mercury content in silver amalgam restorations. White fillings are safe, durable, and widely endorsed by dental associations as the standard of care for cavity treatment today.
The white filling procedure is straightforward and completed in a single appointment. After local anesthesia is administered to ensure comfort, Dr. Barbu removes all decayed tissue and thoroughly cleans the cavity. The composite resin is then applied in thin incremental layers, each carefully shaped to recreate the natural contours of the tooth.
Each layer is cured (hardened) using a specialized blue LED curing light. Once all layers are in place, the filling is shaped, adjusted for bite alignment, and polished to a smooth, natural-looking finish. The entire process typically takes 30–60 minutes per tooth — often less than patients expect — and you can eat normally once the anesthesia wears off. For a comprehensive first look at your oral health, consider a new patient exam if you haven't visited recently.
Because composite bonds directly to the tooth, less healthy tooth structure is removed than with amalgam, and the bond itself reinforces the remaining tooth walls. Patients consistently report that the result looks completely natural — even they can't tell where the filling ends and their natural tooth begins.
Old silver amalgam fillings are not permanent. Over time they expand and contract with temperature changes at a different rate than your natural tooth structure — a process that slowly creates tiny cracks in the surrounding enamel. As these fillings age and the seal between filling and tooth breaks down, bacteria can seep in and cause new decay beneath the restoration.
In addition to structural concerns, silver fillings are visibly dark and obvious against natural tooth color — especially noticeable when laughing or speaking. Many patients choose to replace old amalgam fillings with tooth-colored composite simply to improve their smile's appearance. The replacement process is no more involved than getting a new filling, and the improvement in aesthetics is immediate and dramatic.
If your old silver fillings are cracked, worn, or beginning to fail, replacing them proactively with white composite protects the underlying tooth structure, improves aesthetics, and eliminates exposure to amalgam. Schedule your appointment today and Dr. Barbu will evaluate your existing restorations and recommend the best course of action.
Composite resin fillings offer clear advantages over silver amalgam in both function and aesthetics. Here's why they're the standard of care at Roam Dental:
Composite resin is shade-matched to your natural tooth color so precisely that the filling becomes invisible — no dark metal spots visible when you smile or laugh.
Composite resin contains no mercury or metal components — an important consideration for patients concerned about the amalgam content in traditional silver fillings.
Composite bonding requires a smaller preparation than amalgam, preserving more of your healthy natural tooth structure during the cavity removal process.
The composite resin chemically and mechanically bonds to the tooth structure, reinforcing the remaining walls and reducing the risk of future fracture.
Modern composite resins are highly wear-resistant and can last 7–10 years or more with proper oral hygiene and regular dental care visits.
Aging or cracked amalgam fillings can be replaced with tooth-colored composite for a safer, more attractive restoration that renews both function and appearance.
