Traumatic dental injuries, sorted into families

What counts as one, and what this page is for

The category is wider than most parents expect. It covers a tooth that got jarred and feels odd to bite on, a corner broken off a front tooth, a tooth shoved out of position, a tooth gone from the socket entirely, and injuries to lips, tongue and gums that leave the teeth untouched. Upper front teeth are the ones described most often, which fits the way children land when they fall.

These are common in children. Plenty of them end in a small repair, and plenty in nothing at all.

The trouble is that a mouth injury is hard to read from outside, which is why this page stops short of telling you what to do. It exists so that when you call, you have language for what you are looking at. Acting on it lives in our dental emergencies section.

The families these injuries fall into

Dentistry sorts mouth injuries into a handful of groups, and recognizing which group you are looking at is most of what a parent needs.

• Broken pieces. A corner or edge breaks away. Some breaks stay within the hard outer shell. Deeper ones reach the softer layer beneath, the point at which a tooth starts reacting to cold air. Deeper still and the break reaches living tissue at the center. From outside these look remarkably similar, which is why describing what you can see on the phone matters more than naming it. The front desk will ask for the details they need.
• Teeth that moved. Dentistry groups these under one word, luxation, meaning a tooth is present but no longer sitting where it belongs: loosened in place, tipped backward or forward, pushed partly out so it stands taller than its neighbors, or driven up into the gum so it looks short or missing. That last one sends families searching the grass for a tooth that never left the mouth.
• Teeth that came out. Out of the socket completely, and the one family where the answer changes entirely depending on whether the tooth is a baby tooth or a permanent one.
• Damage below the surface. A root can fracture beneath the gum where nothing shows, and the bone anchoring a tooth can be injured by the same force. Neither is visible to a parent, and both are reasons an X-ray is sometimes the only way to tell.
• The jaw itself. A bite that suddenly meets wrong, or a jaw that will not open and close as it did that morning, moves the situation out of dental territory and into medical.
• Soft tissue only. Lips, tongues, cheeks and gums bleed generously from small wounds, so the amount of blood in a sink says very little about severity.

Baby teeth and permanent teeth are two conversations

A baby tooth sits directly above a permanent tooth still forming in the bone. That unseen neighbor is why an injured baby tooth gets more attention than its remaining time in the mouth would suggest: force that traveled through it can matter for the tooth developing underneath, sometimes years later. One point the American Academy of Pediatric Dentistry treats as settled: a baby tooth that has come out is not placed back into the socket, specifically to protect what is forming below.

A permanent tooth out of its socket is the one situation here where minutes truly matter. The American Academy of Pediatric Dentistry treats it as an immediate emergency and emphasizes keeping the tooth moist rather than letting it dry. That is as far as recognized first aid goes, and as far as any web page should go. Bring the tooth, keep it wet, and let the people looking at your child talk you through the rest.

Telling the two apart mid-crisis is harder than it sounds, since a mouth in the middle childhood years holds both kinds at once. Not being sure what you are holding is fine to say on the phone.

Before the tooth: what outranks it

A dentist is the right call for a tooth and the wrong call for everything else a hard impact can do. Get emergency medical help first, by calling 911 or going to the nearest emergency room, and let the tooth wait, if any of this is true:

• Breathing or swallowing is difficult, or a cough will not settle after the impact
• Your child lost consciousness at any point, seems confused or unusually sleepy, is vomiting, or has a headache that keeps building
• Bleeding will not stop under steady, gentle pressure held in place
• The jaw sits or moves wrong, the bite no longer meets as it did, or the lip or chin feels numb
• A cut crosses the lip border or gapes open, or the injury came from a vehicle, a fall from height, or an animal

No parent has ever regretted having a child checked and sent home. Call us once the medical side is settled and we will take the dental half from there.

The quiet damage a mirror will not show you

What takes the blow is the visible crown. What tends to be injured sits out of view: the blood supply and nerve within the tooth, and the fibers anchoring its root into bone. A parent cannot see either, and neither hurts reliably in proportion to what happened.

Late-arriving signs are the ones families are least likely to connect back to the original day. A tooth that changes color over the following weeks, taking on a gray or brownish cast beside its neighbors. Sensitivity absent on the first day that turns up on the tenth. A small bump on the gum above a tooth months afterward. None of that means anything was missed. It means the effects of an injury can show up later, often enough that we would rather have the original event dated in the chart than reconstructed from memory two years later.

That note in the file is the point of the phone call. It gives whoever examines that tooth later a date to work from.

Who gives the actual steps, and what helps meanwhile

You will have noticed this page does not tell you what to do with the tooth. That is deliberate. Instructions about a child's mouth belong with the people who look inside mouths all day, and the right one shifts with the tooth, the age and what happened. Our emergencies section is where you sort out whether this is a 911 call or a dental call, and the phone is where the handling gets worked out: (239) 482-2722, Monday to Friday, 8 to 5.

What is safe to offer generally, while you wait to be seen, stays at the level of ordinary care. Soft, cool foods, and nothing that asks a sore tooth to do work. Chewing on the other side. Something cold, wrapped in a cloth and rested on the face over a swollen spot. Gentle brushing that does not skip the tender area. Leaving a loosened tooth alone rather than testing it every few minutes, because repeated wiggling is its own small injury. And no aspirin on the gums, which burns tissue rather than soothing it.

What a visit after an injury generally involves

An injury appointment is mostly looking. Your pediatric dentist examines the tooth you are worried about and the teeth flanking it, since neighbors absorb part of the force and rarely get the attention the obvious tooth does. The gum, the lip and the way the bite comes together all get checked. A digital X-ray, taken only as needed, is what reveals a fractured root or a tooth driven somewhere it should not be.

What follows depends on what that exam finds, and is decided with your pediatric dentist rather than in advance. Sometimes it is a repair that day. Often it is a plan and a recheck, because a tooth that has taken a hit is watched over months rather than judged in a single afternoon. Watching is a genuine answer rather than a brush-off, and it works better when we know to watch.
