Dental Fillings in San Rafael
Cavities are one of the most common dental problems, and a filling is the simple, effective way to treat them before they grow. When decay is removed, it leaves a space that needs to be sealed and rebuilt — that’s exactly what a filling does. Modern tooth-colored fillings do this while matching the natural shade of your tooth, so your smile stays seamless and no one can tell you ever had a cavity.
Why Tooth-Colored Fillings?
Composite (tooth-colored) fillings offer real advantages over older metal fillings, both cosmetically and functionally.
- Natural Appearance Matched to your tooth’s color so the repair is invisible.
- Mercury-Free Made from safe, modern composite materials.
- Preserves More Tooth Bonds directly to the tooth, so less healthy structure is removed.
A Quick, Comfortable Procedure
Getting a filling is usually a simple, single-visit procedure. We gently numb the area, remove the decay, and fill the space with composite material that we shape and harden to match your bite. Most fillings take just a short time, and you’ll be back to your day with a fully restored tooth.
Catching Cavities Early
The best time to treat a cavity is before it causes pain. Early decay often has no symptoms, which is why routine exams and X-rays are so important — they let us spot and treat cavities while they’re small and easy to fix. Left untreated, decay can spread and eventually require a crown or root canal, so a timely filling truly is the simpler path.
Protecting Your Teeth Long-Term
A filling restores a tooth, but good habits keep it healthy. Brushing, flossing, limiting sugary foods, and keeping up with cleanings all help prevent new cavities. We’ll also keep an eye on existing fillings at your checkups to make sure they stay in great shape for years to come.
