Inlays and Onlays

People of all ages get dental cavities. They are not just for kids. However, if you’re like many, you’ve heard of dental fillings and crowns as part of tooth decay treatment, but you may be less familiar with inlays and Onlays.

Inlays and Onlays in TCare Dental Centre, Villawood, NSW are similar to tooth-coloured fillings and dental crowns—the latter is used for more severe tooth decay that compromises the integrity of your tooth. Inlays and Onlays typically work well for moderate cavities—decay that is too advanced for a dental filling but not significant enough for a dental crown.

TCare Dental Centre in Villawood, NSW, will always choose the best option for your treated tooth. In some cases, this may be an inlay or Onlays.

What Are Dental Cavities?

A dental cavity means you have an area of decay on your tooth. This can be caused by poor brushing and flossing habits, lack of dental care, or a diet high in acidic and sugary foods and beverages. Most people will have at least one cavity in their lifetime, typically more than one.

At TCare Dental Centre, we believe in prevention and customised treatment plans to lower our patients’ risks for cavities. This may mean one or more dental check-ups and teeth cleans per year.

Treating Dental Cavities

After your dentist in Villawood identifies your tooth cavity through a visual exam or x-ray, we may treat it during your preventive exam or schedule your filling soon after.

This process calls for numbing the treatment site, gently clearing away the decay, and closing your tooth with a tooth-coloured filling, a dental crown, an inlay, or Onlay. You may notice mild tenderness for a few hours when the anaesthetic wears off, but this is treatable with a primary pain reliever.

How Inlays and Onlays Work

An inlay is a solid and sturdy protectant that closes your cavity between the cusps or ridges of a tooth. An Onlay, on the other hand, is designed to protect a larger area, including a cusp. Consider an Onlay dental crown—made of the same strong material—that does not cover your entire tooth. And like tooth-coloured fillings and crowns, inlays and Onlays can blend in with your natural tooth colour.

Proper brushing and flossing and regular dental visits for exams and teeth cleaning, inlays and Onlays could last for a decade or more.

An inlay is a sturdy, solid piece that protects your teeth by closing the cavity between the cusps or ridges of your tooth. It doesn’t cover the entire tooth; it protects the affected or damaged area.

inlay and onlay


An onlay protects a larger area than an inlay, including an entire cusp, but doesn’t cover the entire tooth as a crown would. Onlays are good options to treat large areas of damage that aren’t severe enough to require a crown.
