When a cavity or an old filling is too large for a simple repair but the tooth is still too healthy to cover with a crown, a porcelain inlay or onlay can be the middle ground. These custom restorations are shaped to fit the damaged area exactly, then bonded in place to strengthen what remains of your natural tooth. Because they are made from tooth-colored ceramic, they blend in with your smile.
Empower Dental Rancho offers porcelain fillings, inlays, and onlays as part of our restorative dentistry services. With CEREC same-day technology, many of these restorations can be designed, milled, and placed in a single visit. Our Super GP dentists handle every step in house, and our team speaks English, Spanish, Russian, Arabic, and Armenian.
An inlay or onlay removes far less healthy enamel than a crown, which may help your tooth stay strong for years to come.
Book an exam and we will check the tooth, explain whether a filling, inlay, onlay, or crown fits best, and go over your coverage.

Inlays and onlays are sometimes called indirect fillings or partial crowns. Unlike a standard filling that is placed soft and hardened inside the tooth, they are made as a single solid piece outside the mouth and then bonded in. An inlay fits within the grooves between the cusps, or raised points, of a back tooth. An onlay extends over one or more cusps to protect areas that are cracked or weakened.
Porcelain restorations are a popular replacement for older silver fillings because they are tooth-colored and bond directly to enamel. The National Institute of Dental and Craniofacial Research explains how decay develops and why treating it early helps protect the tooth.
These restorations combine the conservative approach of a filling with much of the strength of a crown.
Only the damaged area is removed, so more healthy tooth structure stays in place.
Porcelain is shade-matched to your tooth and reflects light much like enamel.
A bonded ceramic piece can reinforce weakened walls and cusps during chewing.
CEREC technology lets us complete many restorations in one appointment.

With same-day CEREC technology, most patients finish in one visit, although some cases may need a second appointment.
Digital X-rays and AI-assisted radiograph analysis help us see the extent of decay or damage.
After numbing the area, we remove decay or the old filling and shape the tooth.
A quick scan replaces messy impression trays and records your bite precisely.
Your restoration is designed on screen and milled from a solid block of ceramic.
We bond the piece in place, check your bite, and polish it to a smooth finish.
Your dentist may suggest an inlay or onlay when a tooth needs more than a filling but less than a full crown. Common reasons include:
Small cavities are often best treated with a tooth-colored filling or dental bonding. When damage covers most of the biting surface or the tooth has had a root canal, a dental crown may offer better protection. Inlays and onlays fill the space in between, and we will explain which option fits your tooth after your exam.
Inlays and onlays usually cost more than a direct filling because they are custom made. A very large or deep cavity may still need a crown, and some patients notice mild temperature sensitivity for a short time after treatment. Like any restoration, the edges can develop new decay if plaque is left behind, so daily brushing and flossing matter.
Brush twice a day, floss around the restored tooth, and keep up with routine visits so we can check the margins. If you grind or clench your teeth, a night guard may help protect porcelain and natural enamel alike. Avoid using your teeth to open packages or crack hard shells.
Cost depends on the size of the restoration and the tooth involved. Many PPO plans provide partial coverage for inlays and onlays. We accept all PPO plans in network, along with HSA and FSA. Financing through Alphaeon and Happen Bank can help with any remaining balance, and our financing and insurance page has more details.
If an old filling feels rough, a tooth has started to ache, or you have been told a filling is breaking down, an evaluation can help you understand your options early. Learn more about the equipment in our office on our technology page.

An inlay sits within the grooves between the cusps of a back tooth. An onlay covers one or more cusps as well, which helps protect a tooth that has a weakened or broken point.
For larger areas of damage, they can be. Because they are made as one solid piece and bonded in, they may offer more strength than a large direct filling. Small cavities are often well served by a standard tooth-colored filling.
In many cases, yes. CEREC same-day technology allows us to scan, design, mill, and bond the restoration during a single appointment.
The tooth is numbed before any preparation begins, so most patients feel pressure rather than pain. Mild sensitivity for a short time afterward is common and usually fades.
With good home care and regular checkups, porcelain inlays and onlays can last many years. How long they last depends on your bite, habits such as grinding, and how well the edges are kept clean.
Yes. The porcelain is selected to match the shade of your natural tooth, so it blends in with the surrounding enamel.
Often, yes. If an amalgam filling is worn, cracked, or leaking, we can remove it and restore the tooth with a porcelain inlay or onlay when enough healthy structure remains.
A crown requires shaping the entire tooth. When enough healthy tooth remains, an inlay or onlay lets us keep more of it, which may be the more conservative long-term choice.
Many PPO plans offer partial coverage. We accept all PPO plans in network, along with HSA and FSA, and we will review your benefits before treatment.
