Composite Dental Fillings in Gilbert, AZ
Natural-looking, mercury-free fillings that blend seamlessly with your teeth. Repair cavities while preserving more of your natural tooth structure.
At Dentists 'R Us in Gilbert, AZ, we exclusively use tooth-colored composite resin fillings to repair cavities and restore teeth to their natural appearance. Unlike traditional silver amalgam fillings, composite fillings blend seamlessly with your natural tooth color, bond directly to the tooth structure for a stronger repair, and are completely mercury-free. For most patients across Gilbert, Mesa, Chandler, and the East Valley, composite is the clear choice for cavity treatment.
Dr. Ali Nia has been placing composite fillings for nearly 30 years — long before they became the standard of care. His experience means every filling is precisely shaped, color-matched, and polished to look and feel like a natural part of your tooth.
We do not use amalgam (silver/mercury) fillings. All of our restorations are made with biocompatible, tooth-colored composite resin — a natural-looking option that bonds directly to tooth structure.
Benefits of Tooth-Colored Fillings
Composite fillings offer multiple advantages over traditional amalgam. They match your natural tooth color for an invisible repair, bond directly to enamel and dentin for a stronger, more conservative restoration, require less healthy tooth removal during preparation, do not expand and contract with temperature changes (which can crack teeth over time), and contain absolutely no mercury or other metals.
The result is a filling that looks better, preserves more of your natural tooth, and is made from materials you can feel good about.
The Filling Process
Getting a composite filling is quick, comfortable, and typically completed in a single visit:
Numbing
We apply local anesthesia to ensure complete comfort. The area is completely numb so you can feel comfortable during the procedure.
Decay Removal
Dr. Ali carefully removes the decayed portion of the tooth, preserving as much healthy structure as possible.
Layered Application
Composite resin is applied in thin layers, each shaped to match your tooth's natural contours.
Cure & Polish
Each layer is hardened with a curing light, then the filling is shaped, adjusted for bite, and polished smooth.
Most fillings take 30–45 minutes. You can eat and drink normally once the anesthesia wears off (usually 1–2 hours).
Composite vs. Amalgam Fillings
Composite (Tooth-Colored)
Matches natural tooth color. Bonds to tooth structure. Mercury-free. Requires less tooth removal. Does not expand/contract. Ideal for visible and structural repairs. Lasts 7–10+ years.
Amalgam (Silver/Mercury)
Silver/gray color is visible. Does not bond — held in place by shape. Contains mercury (about 50%). Requires more tooth removal for retention. Expands and contracts with temperature. Slightly more durable under extreme force. Lasts 10–15 years.
Composite resin is a tooth-colored restorative material that allows us to repair many cavities while matching the surrounding tooth more closely than traditional silver-colored restorations. We chose to be a mercury-free practice because we prefer composite for its aesthetics, bonding properties, and patient acceptance.
Cavity? We Can Fix It Today.
Composite fillings are quick, comfortable, and virtually invisible. Most can be completed in a single visit.
Replacing Old Silver Fillings
Many patients ask about replacing their old amalgam fillings with tooth-colored composite. We support this decision when it makes clinical sense — for example, when an old filling is cracked, worn, or leaking, when decay has developed around an existing filling, when the amalgam filling is causing cosmetic concerns, or when you simply want to move away from mercury-containing materials.
Dr. Ali evaluates each filling individually and will honestly tell you whether replacement is beneficial or whether the existing filling is still serving you well. We never recommend unnecessary treatment.
The earlier a cavity is caught, the smaller the filling — and the more tooth structure we preserve. Regular exams with digital X-rays are your best defense against large, costly restorations.
Preventing Future Cavities
The best filling is the one you never need. To minimize your cavity risk, we recommend:
- Brush twice daily — With fluoride toothpaste for at least two minutes
- Floss daily — Cavities between teeth are the most common type we see
- Limit sugar — Frequent sugar exposure is the leading cause of decay
- Get fluoride treatments — Professional fluoride strengthens enamel and prevents cavities
- Consider sealants — Protective coatings for molar grooves where decay often starts

Frequently Asked Questions
Composite fillings typically last 7–10 years with proper care, though many last longer — especially in areas with less chewing force. Regular dental visits allow us to monitor your fillings and catch early signs of wear or breakdown before they become a problem.
Most dental insurance plans cover composite fillings, especially for front teeth. For back teeth, some plans cover composite at the same rate as amalgam; others may cover a portion with the patient paying a small difference. Our team verifies your specific benefits before treatment.
Both materials have advantages. Composite fillings look natural, bond directly to tooth structure (which may preserve more healthy enamel), and contain no mercury. Amalgam fillings can be slightly more durable under extreme chewing force. Most patients and dentists today prefer composite for its appearance and bonding properties.
Composite fillings typically cost $150 to $400 per tooth depending on the size and location. They cost slightly more than amalgam fillings but are overwhelmingly preferred by patients for their natural appearance and mercury-free composition. Insurance covers most or all of the cost for medically necessary fillings.
Composite resin can pick up staining over many years, particularly from coffee, tea, red wine, and tobacco. However, modern composite materials are significantly more stain-resistant than earlier generations. Regular cleanings and polishing help maintain their appearance.
Yes. Many patients choose to replace old amalgam fillings with tooth-colored composite for aesthetic reasons or because the old filling is worn, cracked, or leaking. Dr. Ali evaluates each filling individually and will recommend replacement only when it is clinically beneficial — not just for appearance.
