Composite Fillings Provider · Sunnyvale, CA

A cavity doesn’t go away on its own — left untreated, even a small area of decay can spread deeper into the tooth, turning a simple fix into a much bigger procedure. According to the Centers for Disease Control and Prevention, nearly 21% of adults between the ages of 20 and 64 have at least one permanent tooth with untreated decay, and those with a history of fillings average six filled teeth over their lifetime. The good news: modern composite fillings are quick, comfortable, and designed to blend seamlessly with your smile.

Tooth-colored fillings that restore function and blend seamlessly with your smile.

Signs You May Need a Filling in Sunnyvale

Cavities can progress silently — here are signs to watch for and how composite fillings can help.

Sensitivity to Hot & Cold

Sensitivity to hot, cold, or sweet foods and drinks can signal an early cavity forming beneath the enamel.

Visible Pit or Dark Spot

A visible pit, hole, or dark spot on a tooth is often one of the clearest signs that decay is present.

Pain When Biting or Chewing

Discomfort when biting down can mean decay has progressed closer to the nerve.

Rough or Catching Texture

A rough or catching texture felt with your tongue often points to a chip or cavity forming.

Persistent Tooth Ache

A dull, persistent ache in a specific tooth should never be ignored.

Replacing Old Metal Fillings

For patients with aging amalgam fillings, we offer tooth-colored composite replacements that blend naturally with your smile.

The Composite Filling Experience at Smile Craft Dental

Getting a filling at our Sunnyvale office is a simple, single-visit process. We begin by numbing the area around the affected tooth so the procedure is comfortable from start to finish. Once the tooth is numb, we carefully remove the decayed portion of enamel and clean out the area to prevent bacteria from being sealed in.

What to Expect: The Filling Process

Here is what you need to know about getting a composite filling.

Numbing the Area

We numb the area around the affected tooth so the procedure is comfortable from start to finish.

Removing the Decay

We carefully remove the decayed portion of enamel and clean out the area to prevent bacteria from being sealed in.

Applying the Composite

We apply the composite resin in layers, shaping and sculpting it to match the natural contours of your tooth.

Curing Each Layer

Each layer is hardened using a curing light before the next is added, creating a strong, durable bond.

Polishing & Finishing

We polish the filling so it blends smoothly with the surrounding tooth and feels natural when you bite down.

Composite Filling Cost & Financing

The cost of a composite filling varies based on the size and location of the cavity. We accept most PPO insurance plans and offer Cherry financing so you can get the care you need and pay over time. Call (650) 822-0803 to schedule your consultation and get a personalized estimate.

Caring for Your Filling After Treatment

Once your filling is placed, it typically requires no special maintenance beyond your normal oral hygiene routine. Some patients notice mild sensitivity to temperature for a few days afterward, which usually resolves on its own. Brushing twice daily, flossing, and keeping up with regular cleanings will help your filling last as long as possible and reduce the chance of decay forming around its edges or on other teeth.

When Decay Requires More Than a Filling

If a cavity has progressed extensively or a tooth has cracked under the pressure of long-term decay, a more substantial restoration such as a dental crown may be necessary to fully protect and rebuild the tooth. Sudden or severe tooth pain should never wait for a scheduled visit — our emergency dentistry services in Sunnyvale are available to get you relief as quickly as possible.

Composite vs. Amalgam Fillings

Here's how tooth-colored composite compares to traditional metal amalgam fillings.

Factor Amalgam (Metal) Composite (Tooth-Colored) Appearance Visible silver or gray color Shade-matched to blend with your natural tooth Tooth Preparation Requires removing more healthy tooth structure Bonds directly to the tooth, preserving more natural structure Repairs Harder to repair or touch up Can be repaired or touched up more easily if a small chip occurs Best For Patients with older metal fillings Most patients seeking a natural-looking, conservative restoration

Frequently Asked Questions About Composite Fillings

Answers to the questions patients ask most about composite fillings in Sunnyvale.

What are composite fillings made of?

Composite fillings are made from a mixture of plastic resin and fine glass or ceramic particles, shaded to match your natural tooth color. The material bonds chemically to enamel, unlike amalgam which relies on mechanical retention.

Do composite fillings hurt?

The procedure is done under local anesthesia so you feel no pain during the filling. Mild sensitivity for a few days afterward is normal and usually resolves on its own.

How long do composite fillings last?

Most composite fillings last 7 to 10 years. Smaller fillings in patients with good oral hygiene can last considerably longer. Consistent brushing, flossing, and regular checkups help maximize filling lifespan.

Are composite fillings covered by insurance?

Most PPO plans cover composite fillings as a basic restorative benefit. Coverage for back-tooth composites varies by plan. Smile Craft Dental does not accept Delta Dental. Our team verifies your specific coverage before treatment.

Can I replace my silver fillings with composite?

We do not recommend removing functional amalgam fillings solely for cosmetic reasons. If an existing silver filling is cracked, leaking, or creating sensitivity, replacing it with composite at that point is clinically sound.

How do I care for a composite filling?

Care is the same as for natural teeth: brush twice daily, floss once a day, and keep up with professional cleanings. Avoid chewing hard items like ice or hard candy. A custom night guard protects fillings if you grind your teeth.

Ready to Fix That Cavity?

When a cavity needs attention, choosing the right practice makes all the difference in your comfort and outcome. We accept most major insurance plans and offer payment options to make necessary care accessible, with Spanish-speaking staff available to assist patients who prefer communicating in Spanish. We provide the advanced care you deserve in an environment where you feel valued and supported — contact us to schedule your filling consultation.
