Inlays & Onlays in Bethlehem, PA

A definitive restoration that sits between a filling and a crown, keeping more of your tooth.

An inlay or onlay is a laboratory-made porcelain filling for a tooth that needs more than a regular plastic filling but not a full crown. At Always About Smiles, our Bethlehem, PA dental office, I design inlays and onlays that replace only the damaged part of the tooth and leave the rest of it in place.

Something between a filling and a crown

When a tooth is beyond restoring with a simple composite bonded filling, inlay or onlay, a crown may be recommended to save the tooth. An inlay or onlay sits between the two. Where the walls of the tooth are still sound but the biting surface has gone, I can replace just that part with porcelain made to fit it, and leave the sound tooth alone.

Taking away as little as possible

An inlay replaces the biting surface within the cusps of the tooth, the nooks and crannies in the middle. An onlay goes further and covers one or more of the cusps themselves, which is why it's sometimes called a partial crown. In contrast to complete crowns, which require a large portion of the tooth surface to be trimmed, onlays and inlays only need the damaged part of the tooth to be trimmed.

Porcelain, made to fit exactly

Two visits, two to three weeks apart. At the first I remove the damage, take an impression and fit a temporary; the laboratory builds the inlay or onlay to my design, and at the second visit it's bonded in place and the bite is checked. Porcelain and gold are both options. Patients drive in from Allentown for that work.

What is a dental inlay or onlay?

An inlay or onlay is a single piece of porcelain or gold, made to fit one tooth exactly and bonded into it. An inlay replaces the biting surface inside the cusps; an onlay also covers a cusp, which is why onlays are sometimes called partial crowns. Both are made in a laboratory rather than shaped in your mouth.

How much does an inlay or onlay cost in Bethlehem, PA?

An inlay or onlay is quoted as one fee covering the preparation, the laboratory work and the fitting, and you'll have that figure in writing first. It sits between a large filling and a crown in cost, and I'll price the alternatives beside it so you can compare them honestly. Financing is available.

How long does it take to get an inlay or onlay?

Two visits, about two to three weeks apart. The first prepares the tooth and takes the impression, and you leave with a temporary you can eat with. The laboratory makes the porcelain to my design, and the second visit bonds it in and checks how it meets the tooth above.

What do you do to keep the appointment comfortable?

The numbing is where the care goes. A super numbing gel is placed before the anesthetic, and I buffer the anesthetic chair-side, which adjusts its pH in about ten seconds, resulting in more profound and rapid onset of numbness. We agree on a stop signal before starting, and OraVerse can return the area to normal sensation afterward.

How long does an inlay or onlay last?

These are long-term restorations. Porcelain inlays and onlays, and gold or porcelain-fused-to-metal ones, carry a five-year warranty against fracture with normal use under our Peace of Mind Limited Dental Warranty, when you follow our recommendations for care, cleanings, and treatment. Accidents, sports, grinding and clenching are excluded from that.

Is an onlay better than a crown?

Where the tooth allows it, I'd choose an onlay, because it keeps more of your own tooth. A crown encases the entire surface of the tooth, restoring its natural strength and shape, and that's the right answer when the tooth has broken down too far. An examination and a fiber optic look tell me which one your tooth is.

Frequently Asked Questions

  • Can an inlay replace an old silver filling?

    Often, yes, and it's a common reason patients ask. Where a large old filling has left the tooth weak, an inlay or onlay bonded in supports the tooth rather than wedging it apart. I'll look at what's under the filling first, because that decides between an inlay, an onlay and a crown.
  • Will an onlay show when I smile?

    Not in porcelain, no. The shade is matched to your own teeth and the porcelain is shaped and polished to sit flush with them. Most inlays and onlays go on back teeth in any case, where the biting surface takes the wear and very little shows.
  • Is the tooth sensitive afterward?

    Some tenderness to cold for a few days is normal while the tooth settles, and it eases. If it's still there after a couple of weeks, call the office, because sometimes it's the bite needing a small adjustment, which takes minutes. Don't sit with it.
  • What happens if it comes loose or fractures?

    Come in and let me look at it. A bonded restoration that has come away can often be re-bonded, and a fractured one is remade. Fracture with normal use inside five years falls under our Peace of Mind Limited Dental Warranty, when you follow our recommendations for care, cleanings, and treatment.
  • Does insurance treat an inlay like a filling or like a crown?

    It varies by plan, and it's worth finding out before you decide. We're fee-for-service, we file your claim for you, we're good at it, and we'll push to get you reimbursed. I'll have the office check your plan's wording for inlays before you commit.
