Dental Fillings in Sunnyvale, CA

Natural-Looking Tooth Repair That Lasts

Tooth decay happens—what matters is how you treat it. At Harmony Smile Dental in Sunnyvale, we offer durable, tooth-colored dental fillings that restore your tooth’s strength, protect against further decay, and blend in seamlessly with your natural smile. Led by Dr. Ryan Zhao, our team uses advanced materials and gentle techniques to ensure every filling looks great and feels even better.

If you're experiencing tooth sensitivity, pain when biting, or suspect you have a cavity, we’re here to help with prompt, precise care.

What Are Dental Fillings?

Dental fillings are restorative materials used to repair teeth damaged by decay or minor fractures. They fill the space left behind after the decayed portion of the tooth is removed, preventing bacteria from entering and causing further damage.

At Harmony Smile Dental, we primarily use composite resin fillings—a metal-free, tooth-colored material that bonds directly to your natural tooth structure. This allows for a strong, conservative restoration that preserves more of your healthy tooth.

Signs You Might Need a Filling

Cavities aren’t always obvious at first. Early treatment helps avoid more extensive dental work down the line. You may need a dental filling if you notice:

• Sensitivity to hot, cold, or sweet foods
• A visible hole or dark spot on your tooth
• Sharp pain when biting or chewing
• Food getting stuck in a specific area
• A chipped or cracked tooth

If you're unsure whether you need a filling, Dr. Zhao will perform a thorough exam and digital X-rays to diagnose the issue accurately.

Our Tooth-Colored Filling Process

Getting a dental filling at Harmony Smile Dental is a quick and comfortable experience. Here’s what to expect:

1. Evaluation and Numbing – We start by numbing the area around the tooth to ensure you’re completely comfortable.
2. Decay Removal – Dr. Zhao removes the decayed portion of the tooth with precise instruments.
3. Tooth Preparation – The area is cleaned and shaped to receive the filling.
4. Filling Placement – The composite resin is applied in layers, hardened with a special curing light, and shaped to match your bite.
5. Final Polish – The filling is smoothed and polished for a natural look and feel.

Most fillings can be completed in a single visit, and you can return to your normal activities the same day.

Are White Fillings Right for You?

Tooth-colored fillings are a great option for most patients, whether you're treating a new cavity or replacing an old metal filling. They're especially popular for restoring front teeth or any visible areas where aesthetics matter.

In some cases—such as very large cavities or fractures—Dr. Zhao may recommend an inlay, onlay, or dental crown instead. During your visit, we’ll walk you through your options and help you make an informed choice.
