What are Inlays and Onlays?

Inlays use a restorative material to treat a cavity or area of damage. The material fits into the center of the tooth between the cusps to restore structure and provide support. Onlay also uses restorative material but covers a larger section of the tooth, usually one or more cusps. An onlay is used to treat larger cavities and areas of decay while preserving the remaining tooth.

When do I Need an Inlay or Onlay?

An inlay or onlay can be used to:

  • Fill a cavity that is too large for a filling
  • Avoid the need for a dental crown
  • Add support to a damaged tooth
  • Protect a weak tooth

Your dentist will examine your teeth and decide if an inlay or onlay is the best course of treatment for you, or if you might benefit more from a filling or a crown.

What to Expect During Treatment

Your procedure to receive an inlay or onlay takes two appointments. During your first appointment, Dr. Khan will prepare the tooth for treatment. Cavities, fillings, or areas of decay and damage will be removed. A mold of the tooth will be made using dental putty to create an exact fit for your inlay or onlay. A temporary restoration will be placed to protect your tooth while the inlay or onlay is made. During your first appointment, Dr. Khan might also go over which material will be best for your restoration.

During your second appointment, Dr. Khan will remove the temporary restoration and place your inlay or onlay. Once a good fit has been established, the inlay or onlay will be bonded to the tooth and polished for a smooth finish. Each appointment will take about an hour.

After Treatment

After your inlay or onlay treatment, you might experience some mild discomfort, soreness, and sensitivity that should subside after a couple of days. The look and feel of the new surface of your tooth may also need some getting used to. Over time, your inlay or onlay will blend in with the rest of your teeth for a natural look and feel.

Inlays and onlays provide long-lasting strength and structure. Maintaining good oral hygiene by regularly brushing and flossing can keep your restored tooth and natural teeth healthy. It is also important to attend regular visits to your dentist to check the condition of your inlay or onlay.

Inlays & Onlays Frequently Asked Questions (FAQs)

When do I need an inlay or an onlay?

There are a variety of reasons you may need an inlay or an onlay. If you have a cavity that is too large for a filling, want to avoid a dental crown, need to add support to a damaged tooth, or require protection for a weak tooth, you likely need an inlay or onlay.

What is the difference between an inlay and an onlay?

An inlay is a custom-made filling that fits in between the cusps of a single tooth. An onlay, on the other hand, not only fills the inside of one tooth, but covers the cusp(s) of teeth. It can also extend from the chewing surface to the sides of the teeth.

How are inlays and onlays placed?

To start, Dr. Khan will prepare the tooth and remove any decay. From there, Dr. Khan will take a mold to ensure the inlay or onlay fits your teeth exactly, and a temporary inlay or onlay will be placed. At your next appointment, the temporary restoration will be removed, and your custom inlay or onlay will be placed and bonded to the tooth.

Are inlays and onlays better than fillings?

Inlays and onlays aren’t better than fillings; they are simply different. They are typically better for addressing larger cavities or larger areas of damage. And because they are meant for more extensive damage, they are made of more durable and long-lasting material.

How long do inlays and onlays last?

Inlays and onlays can last for a very long time. Typically, you can expect lasting results with proper care and maintenance. At Ikon Dental Group, Dr. Khan will walk you through how best to take care of your inlays and onlays to ensure they last for years to come.
