Temporary Crown Fell Off? What to Do Before Your Visit

If your temporary crown fell off, it is almost never an emergency, but the tooth underneath is a prepared stump with its outer surface shaved away, and it needs covering again fairly quickly. Keep the temporary somewhere safe, keep the tooth clean, and chew on the other side until it is back on. Most people who call us in Beit Shemesh about this were eating something sticky, felt it lift, and have nothing worse than cold sensitivity to show for it. Here is what to do in the first few minutes, when it is reasonable to reseat it yourself, and the few signs that make it worth calling today rather than waiting for your fitting appointment.

Is a Lost Temporary Crown an Emergency?

No, in almost every case. A temporary crown is held on with cement chosen to be weak on purpose, because it has to come off cleanly and undamaged when the permanent crown is fitted. Cement that lets go a week early is doing roughly what it was designed to do, just at an inconvenient moment.

The reason it still matters is not pain. It is that the prepared tooth under a temporary has been reduced in size, and teeth left uncovered start to drift within days. The neighbouring teeth lean in slightly and the opposing tooth comes down a little. Your permanent crown was made from a scan or impression of the mouth as it was on the day it was taken, so if the space changes, the lab-made crown may need adjusting or, occasionally, remaking. That is the real cost of leaving a stump bare for two weeks, and it is quiet the whole time it is happening.

What to Do in the First Few Minutes

Nothing here is complicated, and all of it protects the tooth until you can be seen:

  • Find the temporary and keep it. Rinse it under water, dry it, and put it in a small container. Even a chipped temporary can often be reused for the few days that remain.
  • Clean the exposed tooth gently. Brush it softly and rinse with warm salt water. Food packs into the gap around a prepared tooth easily, and that is what makes the gum sore.
  • Chew on the other side. A prepared stump is narrower than a whole tooth and can chip under a hard bite.
  • Expect some cold sensitivity. The tooth still has a live nerve unless it has had a root canal, and cold air, cold water, and sweet things will reach it. An over-the-counter painkiller taken as directed handles most of it.
  • Leave the floss alone on that tooth until it is covered again, or floss out sideways rather than pulling straight up.

You will also want to stop checking it with your tongue every thirty seconds. Everyone does it, it changes nothing, and it makes the gum more tender by evening.

Can You Put a Temporary Crown Back On Yourself?

Often yes, and unlike a permanent crown, this is a normal thing to be asked to do. Pharmacies sell temporary dental cement for exactly this situation. Clean the inside of the temporary and dry the tooth, put a thin layer of cement inside the crown, seat it in the right orientation, bite gently to settle it, and wipe away what squeezes out around the gum.

Two rules. It has to go on without force. If you find yourself pushing, stop, because a temporary seated crooked can bruise the gum and throw off your bite. And never use household superglue. It is not made for the mouth, it is difficult to remove without damaging the prepared tooth, and it can wreck a temporary that would otherwise have lasted until your fitting appointment. If a filling rather than a crown has come out, our guide on a temporary filling that fell out covers that case, and if this was a permanent crown rather than a temporary, read what to do when a crown falls off instead.

If It Comes Off on a Friday Afternoon in Beit Shemesh

Timing decides how much of a problem this is. We are open Sunday to Thursday 8:00 AM to 8:00 PM and Friday 8:00 AM to 2:00 PM, and closed Saturday. A temporary that lifts on a Tuesday evening is a phone call and a short appointment the next morning. One that lifts at three on a Friday afternoon means the tooth is uncovered across Shabbat, which is where a tube of temporary cement from the pharmacy earns its price.

That is worth knowing in advance if you are mid-treatment and your fitting appointment is still a week or two away. Buy the cement when the temporary goes on, not after it falls off, and keep it at home. Ramat Beit Shemesh is about two kilometres from the chair, so getting seen here is quick during the week, but Friday afternoon and Saturday are the gap. After-hours emergency treatment is available outside our normal hours if the tooth becomes painful rather than just bare.

Why Temporary Crowns Come Off

Almost always the cement, and almost never anything that was done wrong. Beyond the weak cement, the usual reasons are sticky and chewy foods, floss pulled straight up out of the gap, a short or steeply tapered prepared tooth that gives the temporary less to grip, and night-time grinding. A temporary on a back molar carrying most of your chewing force has a harder life than one on a front tooth.

It is also more common in the first day or two after it is fitted, while you are still learning what that side of your mouth can handle. If yours has come off twice in a week, say so when you call. A temporary that keeps lifting sometimes needs reshaping or a different cement rather than another attempt with the same one, and occasionally it is telling us something about the bite that is worth catching before the permanent crown goes on. If the tooth itself has been aching rather than just feeling sensitive, our guide to tooth pain after a crown goes through what that usually means.

When a Loose Temporary Is More Than a Nuisance

Most of these are a routine appointment. A few things move it up the list:

  • Throbbing or building pain from the tooth, rather than short cold sensitivity that fades.
  • Swelling of the gum, cheek, or face near the tooth.
  • A bad taste or discharge coming from around the prepared tooth.
  • The temporary came off with a piece of tooth inside it, or the stump feels sharp or broken.
  • Your bite feels high or wrong after you reseated it yourself.
  • More than about a week left before your fitting appointment, with the tooth still uncovered.

And the part nobody selling appointments wants to write down: if the temporary is back on, the tooth is comfortable, and your fitting appointment is in two or three days anyway, you do not need an extra visit. Come as planned and mention it at the chair. Equally, if the swelling is spreading toward your eye or down into your neck, you have a fever alongside a swollen face, or you are having any trouble breathing or swallowing, that is a hospital emergency room and not a dental clinic. Our guide to when a toothache is a real emergency sets out where that line sits.

What Happens When You Come In

The appointment itself is short. We clean the old cement off the temporary and off the prepared tooth, check the stump for decay or a chip that might have been what loosened it, recement the temporary, and check the bite so it is not sitting high. If the temporary is broken beyond reuse, a new one is made at the chair.

We also check whether the permanent crown is still going to seat, which is the whole point of the exercise. If the tooth was left uncovered long enough for anything to shift, it is better to know now than at the fitting appointment. If you are still waiting on the lab, our guide on how long to wait for a crown after a root canal explains why that gap exists and why the temporary matters during it.

If your temporary crown has come off, call or WhatsApp 055-985-8845 and we will get the tooth covered again. Ramat Beit Shemesh Urgent Dental Care is at Harav Kook 28/1 in Beit Shemesh, open Sunday to Thursday 8:00 AM to 8:00 PM and Friday 8:00 AM to 2:00 PM, with after-hours emergency treatment outside those hours.

Our dental first aid page explains how urgent problems are handled here.

For guidance from sources with nothing to sell, the ADA's MouthHealthy explains what dental crowns are and how they are used, and the American Association of Endodontists covers how a treated tooth is restored and looked after.
