Fillings vs. Inlays vs. Onlays: Which Is Best for You?

A close-up shot of a woman's teeth during a dental exam If you have a cavity or tooth damage, you may be wondering which type of restoration is right for you. Three common options are inlays, onlays, and fillings. Each serves a similar purpose — to improve the function and structure of a tooth — but they differ in material, coverage, and durability.

At Softouch Dental Care, Dr. Michael Chung, an LVI Fellow with over 15 years of advanced training, and Dr. Ashley Chung, a member of the prosthodontic honor society, offer personalized care to determine the ideal solution for your smile.

What Are Dental Fillings?

Dental fillings are generally used for small to moderate cavities. They are made of composite resin or amalgam and placed directly into the cavity after extracting decayed tooth material.

Fillings are best for:

  • Minor decay
  • Quick, cost-effective repairs

Considerations:

  • They are less durable than other options.
  • They may need replacement over time.

What Are Inlays?

Inlays are custom-made restorations created in a dental lab and bonded within the grooves of a tooth. They are often used when a filling isn’t sufficient, but the tooth doesn’t need a full crown.

Inlays are best for:

  • Moderate decay or damage
  • Strengthening the chewing surface

Considerations:

  • They’re more durable than fillings.
  • They require two visits for placement.

What Are Onlays?

Onlays are similar to inlays but extend to cover one or more cusps of the tooth. They are sometimes referred to as “partial crowns” because they provide broader coverage.

Onlays are best for:

  • Larger areas of damage
  • Preserving healthy tooth structure

Considerations:

  • They offer high strength and durability.
  • They’re more conservative than full crowns.

Which Is Right for You?

The best restorative treatment depends on the size and location of your cavity, your bite, and your long-term goals. A consultation with a skilled dentist, like Dr. Michael Chung or Dr. Ashley Chung, can help you weigh the pros and cons of each and ensure you make an informed decision.
