Dental Crowns, Onlays & Inlays

Dental Crowns in Edison, NJ

Depending on the remaining structure in your natural tooth, we come up with a plan of whether a crown or an inlay or onlay is recommended. A crown is a cap that covers a whole tooth, for when there isn't enough left to hold a filling. Two visits, about two weeks apart, with a temporary in between. An onlay or inlay is porcelain type filling that fits your tooth like a puzzle piece.

What a crown or onlay actually does

A crown is a cap that covers a whole tooth, from the gumline up. You need one when there isn't enough healthy tooth left to hold a filling: after a large cavity, a crack, a broken cusp, or a root canal that left the tooth hollow.

A filling fills a hole in a tooth and leans on the tooth around it for strength. Depending on the size of the filling, it may require a stronger material such as an onlay or inlay.

Porcelain or zirconia?

We place two kinds of crown, and which one a tooth gets comes down to where it sits in your mouth and how hard you chew. You don't need to memorize this, because we'll tell you which we would use and why, but it's worth knowing a choice is being made on your behalf.

Porcelain (all-ceramic)Best for: Front teeth, and any tooth that shows when you smile.Trade-off: Catches light the way a natural tooth does, which nothing else quite matches. Less forgiving of heavy grinding.
ZirconiaBest for: Molars, and anyone who grinds or clenches.Trade-off: Very hard to break, which is the whole point at the back of the mouth. Slightly less lifelike up close, which matters at the front and not behind it.

Which one you'll probably get

Front tooth: porcelain, almost always. Back molar: zirconia, usually. The teeth in between, and any mouth that has already broken a crown once, are where the conversation is worth having. And it is a conversation, not a form you sign.

What happens if you wait

A cracked tooth doesn't heal, and cracks travel downwards. A crack in the enamel becomes a crack into the nerve, which is a root canal. A crack that reaches below the gumline is usually an extraction. The tooth that needs a crown this year is often the tooth that needs more than a crown next year.

That said, not every crack needs a crown today. Some are worth watching, and we'll tell you when that's the honest answer.

What a crown costs

Crowns are billed as a major service, which on most dental plans means the plan covers part of the cost rather than most of it, and new plans sometimes hold a waiting period before that coverage starts at all. What you actually pay turns on your plan, your deductible, and how much of your annual maximum is left.

So we verify your benefits with your carrier before the appointment, and we give you the cost of the work before we start it. If the timing is wrong for you (a maximum that resets in January, say), tell us, because there's usually more than one way to sequence the work.

Crown (Porcelain)

Full-coverage restoration for a damaged or weakened tooth.

Crown (Zirconia)

Full-coverage restoration in a harder material, for molars and heavy bites.

See the insurance we accept, or call (732) 985-1120 and we will verify your benefits before you come in.

How a crown gets made

Two visits, about two weeks apart, and one of them is much shorter than the other.

  1. We look, and we say what we would do

    An exam and an X-ray, and then a straight answer: a crown, a filling, or nothing yet. If the nerve inside the tooth is already infected, a root canal comes first and the crown goes on afterwards to protect what's left.

  2. The prep visit

    The tooth is numbed and shaped down so a crown can fit over it. We take an impression, match the shade against your other teeth, and cement a temporary crown before you leave. This is the longer of the two appointments.

  3. About two weeks at the lab

    Your crown is made to that impression and that shade. You wear the temporary meanwhile. It looks like a tooth, and it's deliberately not as strong as one, which is what the next section is about.

  4. The fitting visit

    The temporary comes off, the crown goes on, and we check three things before anything is permanent: that it fits, that the color sits right next to the teeth either side, and that your bite closes the way it did before. Then it's cemented. This visit is short and usually needs no numbing at all.

Does getting a crown hurt?

The prep visit is done with the tooth numbed, so what you feel is pressure and vibration rather than pain. The fitting visit two weeks later usually needs nothing at all.

The honest discomfort is in between. A freshly prepped tooth can be sensitive to cold and to pressure for a few days, and a temporary often feels slightly bulky against the tongue until you stop noticing it, which most people do within a day.

Looking after the temporary

A temporary crown is cemented with something deliberately weak, because it has to come off again in two weeks. Treat it accordingly: chew on the other side where you can, skip anything sticky (caramel, chewing gum, crusty bread), and when you floss that tooth, pull the floss out sideways rather than snapping it back up, or you'll lift the temporary off with it.

If it does come off, keep it and call us. It isn't an emergency, but don't leave the tooth bare for days: neighboring teeth drift, and a tooth that has drifted is a crown that no longer fits.

Bridges: crowns that span a gap

A bridge is this same procedure applied to a missing tooth. Crowns go on the teeth either side of the gap, joined to a replacement tooth in the middle, and we make them here on the same two-visit pattern in the same two materials.

A bridge asks the neighboring teeth to carry the extra load. That makes it a good answer when those teeth already need crowning anyway, and a weaker one when they're perfectly healthy. Where several teeth in a row are missing, dentures are usually the better conversation to have.

Frequently asked questions

Book Appointment
How long does a dental crown last?

Ten to fifteen years is the usual range and plenty last longer. What decides it is rarely the material: grinding, gum health, and whether decay starts at the edge where the crown meets the tooth matter more. The crown itself can't decay. The tooth underneath still can, which is why a crowned tooth still gets flossed and still gets checked.

Do I need a root canal before a crown?

Only if the nerve is involved. A crown protects the outside of a tooth; a root canal treats the inside of one. Plenty of teeth need one without the other. If the nerve is already infected, the root canal comes first and the crown goes on afterwards, because a tooth that has had its nerve removed is more brittle and wants covering.

Root canal treatment
What if my temporary crown comes off?

Keep it, and call us at (732) 985-1120. It isn't an emergency and it doesn't mean anything has gone wrong. Temporaries are cemented loosely on purpose. Don't leave the tooth bare for several days, though, because the teeth either side can drift far enough to stop the finished crown fitting.

Crown or filling: how do you decide?

By how much healthy tooth is left holding everything together. The rough rule is that when a filling would end up wider than the tooth structure around it, the filling is relying on something too thin to rely on, and a crown is the more honest answer. We'll show you what we're looking at on the X-ray.

Does insurance cover a crown?

Usually in part. Most plans treat crowns as a major service, cover a share of the cost rather than the bulk of it, and some new plans apply a waiting period before that starts. We check your specific benefits with your carrier before the appointment so the number is known before the work is, not after.
