Crown Fell Off and There Is No Tooth Left: What Now?

Why There Seems to Be No Tooth Under the Crown

A crown only holds if there is tooth to hold onto. When there is not much, it was usually built on one of these:

• A core or post. After a root canal, a tooth is often rebuilt with a filling material or a small post, and the crown sits over that. If the whole thing comes out together, the crown looks like it has a tooth inside it, and your mouth looks empty.
• Decay under the crown. Decay can work under the edge of a crown for years without pain, hollowing out what the crown was cemented to. The crown comes off, and the tooth is soft or crumbles.
• A fracture at the gum line. The tooth snapped, usually under biting force, and the crown went with the broken part.

Most people who come to us with this have already poked at it with a tongue for a day or two and hoped it would turn out to be less than it looks. Fair enough, but the tongue is a poor judge of what is under the gum.

What to Do Tonight

• Rinse gently with warm salt water, especially after eating.
• Keep the crown, and anything that came out with it, in a small container. Even a crown that cannot be reused tells us how the tooth was built.
• Chew on the other side. A thin stump can fracture further.
• Cover a sharp edge with pharmacy temporary filling material or dental wax if it is cutting your tongue or cheek.
• Take ibuprofen or paracetamol as directed on the packet if it aches.
• Do not use superglue, and do not press the crown back on over a hollow tooth. It traps bacteria against what is left.

What We Check, and What Can Be Done

The first step is an X-ray. It shows how much root there is, whether the root is cracked, and whether there is infection at the tip. From there it usually goes one of three ways.

• Enough tooth above the gum. The tooth is cleaned out, rebuilt and a new crown is made. If the old one fits, it is sometimes recemented, though not over decay.
• The tooth is below the gum line but the root is sound. It may be possible to expose more of it so a crown has something to grip, or to rebuild it with a post. This is not always possible, and it depends on the length and strength of the root.
• The root is cracked, split, or too decayed to hold anything. Then extraction is the honest answer, followed by an implant or another way to replace it.

If the tooth has no nerve left, it will not hurt in the usual way, which is exactly why this gets left. A tooth that has lost its crown still needs to be seen. For more on how crowns and root canals fit together, see root canal and crown.

When It Is Urgent, and When It Is Not

A painless, quiet tooth with no swelling can wait a few days for an appointment. Protect it, chew elsewhere and book.

See someone the same day if you have a throbbing ache, pain on biting, a pimple-like bump on the gum, or a bad taste. Those suggest infection, and we have a page on tooth abscess treatment that explains what that involves.

Go to a hospital emergency room, not a dental clinic, if swelling is spreading across your face or neck, or you have trouble swallowing or breathing, or you have a fever with facial swelling.

If It Happens Before Shabbat in Beit Shemesh

Crowns come off at the Friday meal more often than on a quiet Tuesday. Our hours are Sunday to Thursday 8:00 AM to 8:00 PM and Friday 9:00 AM to 5:00 PM, and Shabbat is reserved for genuine emergencies only. A painless tooth with no tooth left does not need to interrupt Shabbat: cover it, chew carefully and call on Sunday morning. Swelling or severe pain is different, and that is what the after-hours line is for.

Dr. Joel trained in the US and treats in Hebrew and English, so you can describe the tooth precisely rather than translate your pain on the phone. Before you come, it helps to know which tooth it was, how long ago the crown went on, and whether it had a root canal.

When You Do Not Need Us

If the crown came off cleanly, the tooth underneath is intact, and nothing hurts, you do not need an emergency visit. It can wait for a routine slot in the next few days. If you already have a dentist who made the crown, ask them first; they have your records. And if the crown is the temporary one, the situation is different and a temporary crown that fell off has its own page.

If your crown fell off and there is not much tooth left, call or WhatsApp 055-985-8845. We are at Harav Kook 28/1, Beit Shemesh, we treat in English and Hebrew, and same-day appointments are possible. Our dental crown page explains how crowns are fitted and replaced, and crown fell off: what to do covers the first steps in more general terms.
