Inlays & Onlays in Sunnyvale, CA

A Durable, Conservative Option for Tooth Restoration

When a tooth is too damaged for a simple filling but doesn’t require a full dental crown, inlays and onlays offer a reliable middle ground. At Harmony Smile Dental, we use these custom restorations to rebuild the strength and structure of compromised teeth without removing excessive healthy enamel.

Led by Dr. Ryan Zhao, our team combines advanced restorative techniques with digital precision to deliver long-lasting inlays and onlays that look and feel natural. Whether you're dealing with decay, a fractured tooth, or an old failing filling, we’ll help you find the right solution to restore function and protect your smile.

What Are Inlays and Onlays?

Inlays and onlays are indirect restorations, meaning they are custom-crafted outside the mouth (usually in a lab) and then permanently bonded to the tooth. They are made from durable, tooth-colored materials such as porcelain or composite resin, offering strength and aesthetics.

• Inlays fit within the cusps (or biting surfaces) of a tooth—typically used for smaller areas of decay or damage.
• Onlays extends over one or more cusps and are used when more substantial restoration is needed but a full crown isn't warranted.

Unlike standard dental fillings, these restorations are precisely shaped to fit your tooth and restore your bite alignment with minimal alteration to the natural structure.

Benefits of Choosing Inlays and Onlays

• Stronger than traditional fillings – Ideal for moderate damage or wear
• Preserve more natural tooth structure than full crowns
• Custom-fit for optimal comfort and function
• Resistant to stains and fracture
• Blend seamlessly with your natural teeth

Many patients who initially think they need a crown are pleasantly surprised to learn that an onlay provides a more conservative—and often longer-lasting—alternative.

When Is an Inlay or Onlay Recommended?

Dr. Zhao may recommend an inlay or onlay if:

• You have a large cavity that’s too extensive for a filling
• Your tooth has been weakened by wear, fracture, or repeated dental work
• You want a stronger, longer-lasting option than a filling
• Your bite needs to be precisely restored to prevent further damage

These restorations are especially common on molars and premolars, where chewing pressure is greatest.

What to Expect During Treatment

Initial Visit – Evaluation & Impressions

We begin by thoroughly evaluating your tooth using digital imaging tools. If an inlay or onlay is appropriate, Dr. Zhao will gently remove damaged or decayed areas, clean the tooth, and take a digital impression with our iTero scanner. A temporary restoration will be placed while your final piece is crafted.

Second Visit – Placement & Bonding

Once the custom inlay or onlay is ready, we remove the temporary, confirm the fit, and bond the final restoration to your tooth. The result is a natural-looking, precisely contoured surface that supports long-term bite strength.

Long-Term Care for Inlays & Onlays

Inlays and onlays are incredibly durable but still require proper maintenance. Here's how to protect your restoration:

• Brush and floss thoroughly each day
• Avoid chewing hard objects like ice or pens
• Maintain regular dental cleanings and exams
• Wear a night guard if you grind your teeth

With consistent care, these restorations can last 10 years or more.
