Dental and Mouth Injuries

Dental and mouth injuries can affect the teeth, gums, lips, tongue, cheeks, jaw, or supporting bone. They commonly occur during sports, falls, vehicle accidents, workplace incidents, or direct blows to the face.

Some injuries are immediately obvious, such as a broken tooth, deep cut, or knocked-out permanent tooth. Others may initially appear minor even though the tooth root, dental pulp, supporting ligament, jaw, or neighboring teeth have been damaged.

Prompt evaluation can help control bleeding, relieve pain, identify hidden damage, and improve the possibility of preserving injured teeth. Call 911 or seek emergency medical care for difficulty breathing or swallowing, severe facial or jaw trauma, loss of consciousness, uncontrolled bleeding, or symptoms of a serious head or neck injury.

What Is Considered Dental Trauma?

Dental trauma includes any injury involving the teeth or the tissues that support and surround them.

Common traumatic dental injuries include:

• Chipped, cracked, or fractured teeth
• A tooth that has been loosened by an impact
• A tooth pushed inward, outward, or sideways
• A knocked-out permanent tooth
• Damage to an existing crown, filling, bridge, or denture
• Cuts or punctures involving the lips, gums, tongue, or cheeks
• Injury to the tooth root or supporting bone
• Jaw pain or a suspected jaw fracture
• Bleeding from the gums or an empty tooth socket

The seriousness of the injury depends on the force of the impact, the structures involved, the patient’s age, and how quickly professional care is received.

When to Call a Dentist After a Mouth Injury

Contact a dentist promptly when an injury involves a tooth, dental restoration, gum tissue, or the way the teeth fit together.

Urgent dental evaluation is appropriate for:

• A broken, chipped, or cracked tooth
• A permanent tooth that feels loose
• A tooth that has shifted from its normal position
• A knocked-out permanent tooth
• Pain when biting after an impact
• New sensitivity following an injury
• Bleeding around a tooth
• A damaged or displaced crown or filling
• A cut involving the gums or tissue around a tooth
• A change in the bite after trauma
• Tooth discoloration developing after an injury
• Persistent pain, swelling, or tenderness

Even a tooth that looks normal may have damage beneath the surface. A dental examination and imaging may be necessary to evaluate the root, pulp, socket, and supporting bone.

When to Go to the Emergency Room

A hospital emergency department is appropriate when an oral or facial injury involves a serious medical risk beyond the tooth itself.

Call 911 or go to the nearest emergency department for:

• Difficulty breathing, swallowing, or speaking
• Loss of consciousness
• Confusion, repeated vomiting, unusual drowsiness, or faintness
• Symptoms of a concussion or serious head injury
• Severe facial or jaw trauma
• A suspected broken jaw
• Heavy or uncontrolled bleeding
• A deep facial or oral wound
• Rapidly increasing swelling of the mouth, face, jaw, or neck
• A tooth or dental fragment that may have been inhaled
• Neck pain or a suspected spinal injury
• Dental trauma accompanied by another major bodily injury

After immediate medical risks are treated, follow-up dental care may still be necessary to evaluate and restore injured teeth.

Review our guide explaining when to choose an emergency dentist or emergency room.

What to Do Immediately After a Dental Injury

Remain calm and first determine whether the injured person has any life-threatening symptoms.

When emergency medical care is not required:

• Rinse the mouth gently with clean water
• Use clean gauze to apply light pressure to minor bleeding
• Apply a cold compress outside the face for short intervals
• Locate and save any tooth fragments or dental restorations
• Avoid chewing on the injured side
• Do not move or repeatedly test a loose tooth
• Contact a dentist promptly
• Describe how the injury occurred and when it happened

Do not delay medical care while attempting to locate a tooth fragment or control a severe injury at home.

Chipped or Fractured Tooth

A chipped tooth may involve only the outer enamel or extend into deeper tooth structure. A more significant fracture can expose dentin, reach the dental pulp, or split the tooth below the gumline.

Signs of a significant fracture include:

• Visible loss of tooth structure
• A sharp or jagged edge
• Pain when biting or chewing
• Temperature sensitivity
• Visible pink or red tissue inside the tooth
• Bleeding from the center of the tooth
• A crack extending toward or beneath the gumline
• Movement of part of the tooth

Save any tooth fragments and bring them to the dental appointment. Avoid chewing with the injured tooth and do not attempt to repair it with household glue or another non-dental material.

Learn more about the signs and treatment of a broken tooth.

Loose Permanent Tooth After an Injury

A permanent tooth that becomes loose after an impact may have damage to its supporting ligament, socket, root, or surrounding bone.

Do not repeatedly push, wiggle, or test the tooth. Avoid biting with it and contact a dentist promptly.

The dentist may need to:

• Evaluate the amount and direction of movement
• Check whether the tooth has shifted position
• Examine the surrounding gums and bone
• Test the health of the dental pulp
• Use dental imaging to look for root or bone fractures
• Stabilize the tooth with a flexible dental splint
• Monitor the tooth over time

A loose permanent tooth should not be ignored simply because it remains in the mouth. Review the Apex Dental guide to loose teeth for additional information.

Displaced or Pushed-In Tooth

An impact can push a tooth inward, outward, sideways, or partially out of its socket. This is different from a tooth that has been completely knocked out.

Signs of displacement may include:

• The tooth appearing shorter or longer than neighboring teeth
• A tooth positioned at an unusual angle
• A sudden change in the bite
• Bleeding around the gumline
• Difficulty closing the teeth together
• Pain or movement when the tooth is touched

Do not force the tooth back into position. Avoid biting on it and contact a dentist immediately. Professional repositioning and stabilization may be needed.

Knocked-Out Permanent Tooth

A permanent tooth that has been completely removed from its socket is a time-sensitive dental emergency.

Take the following steps:

• Locate the tooth immediately
• Pick it up by the crown, not the root
• Do not scrub, scrape, or disinfect it
• If dirty, rinse it gently and briefly
• Replant it when this can be done safely
• Keep it moist if it cannot be replanted
• Contact a dentist immediately

Do not replant a knocked-out baby tooth. Replanting a primary tooth can damage the developing permanent tooth beneath it.

See the complete guide for a knocked-out permanent tooth.

Injured Baby Tooth

A baby tooth can become chipped, loosened, displaced, or knocked out after a fall or impact.

A child should receive dental evaluation when:

• The tooth has shifted position
• The child cannot bite normally
• The tooth is very loose
• There is significant pain or swelling
• The tooth has been pushed into the gum
• A large portion of the tooth is missing
• Bleeding does not stop with gentle pressure
• The tooth becomes dark or discolored
• Swelling or drainage develops later

Do not place a knocked-out baby tooth back into its socket. Save any fragments and bring them to the dental appointment.

Cuts to the Lips, Tongue, Gums, or Cheeks

Soft-tissue injuries can bleed heavily because the mouth has an extensive blood supply. Some minor cuts can be managed temporarily with pressure, while deeper wounds may require medical treatment.

For a minor oral cut:

• Rinse gently with clean water
• Remove visible loose debris carefully
• Apply clean gauze with steady, gentle pressure
• Use a cold compress outside the mouth for swelling
• Avoid repeatedly removing the gauze to inspect the wound

Seek urgent medical care for:

• Heavy bleeding that does not slow with pressure
• A deep, wide, or gaping cut
• A wound extending through the lip or cheek
• A large tissue flap
• A contaminated wound
• A foreign object embedded in the tissue
• A significant bite injury
• Difficulty breathing or swallowing

Do not attempt to remove a deeply embedded object yourself. Stabilize it when possible and seek emergency care.

Bitten Tongue or Lip

A fall, collision, seizure, or sudden impact may cause a person to bite the tongue or lip.

Apply clean gauze and gentle pressure to control minor bleeding. Use a cold compress outside the area to help limit swelling.

Seek emergency medical care when:

• The bleeding is heavy or uncontrolled
• The cut is deep or widely separated
• A portion of tissue is severely damaged
• The tongue is swelling rapidly
• Breathing or swallowing is affected
• The injury occurred during a seizure or loss of consciousness

Dental evaluation may also be needed because the same impact may have cracked, loosened, or displaced a tooth.

Jaw Injury or Suspected Jaw Fracture

A severe blow to the face can injure the jaw joint, fracture the jawbone, or alter the way the teeth fit together.

Warning signs include:

• Severe jaw pain
• Difficulty opening or closing the mouth
• The teeth no longer fitting together normally
• Numbness of the lip, chin, or face
• Visible facial asymmetry
• Swelling or bruising along the jaw
• Movement or instability of the jaw
• Bleeding from the mouth
• Loose groups of teeth

Do not attempt to reposition the jaw. Support it gently and seek emergency medical care. Avoid eating or drinking until the injury has been professionally evaluated.

Dental Injury With a Head Injury

A fall or impact strong enough to damage the teeth may also cause a concussion or another head injury.

Call 911 or seek emergency medical care for:

• Loss of consciousness
• Confusion or memory loss
• Repeated vomiting
• Severe or worsening headache
• Unusual drowsiness
• Slurred speech
• Unequal pupils
• Weakness or poor coordination
• Seizure activity
• Clear fluid or blood from the nose or ears

Medical stabilization takes priority over the dental injury. After the person is medically cleared, arrange dental evaluation for the teeth and surrounding tissues.

Damaged Crown, Filling, Bridge, or Denture

An impact may loosen, fracture, or dislodge an existing dental restoration.

When this occurs:

• Remove any loose item from the mouth if it could be swallowed
• Save the restoration or fragments
• Keep them in a clean container
• Avoid chewing on the affected side
• Do not use household glue
• Do not force a crown or appliance back into place
• Contact a dentist promptly

A damaged restoration may conceal a fracture in the supporting tooth. Learn what to do for a lost crown or filling.

What to Do With Tooth Fragments

Save fragments from a chipped or broken tooth whenever possible.

Place the fragments in a clean container and bring them to the dental appointment. Do not scrub them, alter their shape, or attempt to glue them back onto the tooth.

Depending on the condition and location of the fracture, the dentist may be able to use the fragment or restore the tooth with bonding, a filling, a crown, or another treatment.

How to Control Minor Bleeding

For minor bleeding involving the gums, lips, tongue, or cheek:

• Use clean gauze or a clean cloth
• Apply steady, gentle pressure
• Keep the person seated upright when appropriate
• Avoid frequent checking that disrupts clot formation
• Use a cold compress outside the mouth for swelling

Do not pack unidentified substances into the wound. Seek emergency medical care when bleeding remains heavy, does not slow with pressure, or occurs with faintness, weakness, breathing difficulty, or major facial trauma.

How to Reduce Swelling After an Injury

A cold compress applied outside the face may help limit discomfort and swelling during the initial period after an injury.

Wrap the cold source in a thin cloth and use it for short intervals. Do not place ice directly against the skin, gums, or injured tooth.

Increasing swelling, facial asymmetry, difficulty opening the mouth, or swelling that affects breathing or swallowing requires prompt professional evaluation.

What Not to Do After a Mouth Injury

Avoid actions that may worsen the damage or interfere with treatment.

• Do not ignore a loose or displaced permanent tooth
• Do not force a tooth back into position
• Do not scrub the root of a knocked-out tooth
• Do not replant a baby tooth
• Do not use household glue on a tooth or restoration
• Do not remove an embedded object from a deep wound
• Do not place aspirin directly on the gums
• Do not continue sports or strenuous activity after a head injury
• Do not eat hard foods with an injured tooth
• Do not delay emergency medical care for serious symptoms

Pain relief does not confirm that the teeth, roots, or supporting bone are undamaged.

How a Dentist Evaluates Dental Trauma

Evaluation begins with a discussion of how and when the injury occurred, whether the patient lost consciousness, and whether any tooth or fragment is missing.

The dentist may:

• Examine the teeth, gums, lips, tongue, and cheeks
• Check for cracks, fractures, and displacement
• Evaluate tooth movement and stability
• Assess how the teeth fit together
• Test tooth sensitivity and pulp response
• Examine the jaw and supporting tissues
• Use dental X-rays or other imaging
• Look for root fractures or bone injuries
• Document the injury for future comparison

Some complications appear later, so follow-up examinations may be necessary even when the tooth initially seems stable.

How Dental and Mouth Injuries Are Treated

Treatment depends on the type, location, and severity of the injury.

Possible treatment includes:

• Smoothing or bonding a chipped tooth
• Reattaching a tooth fragment when appropriate
• Placing a filling or dental crown
• Repositioning and stabilizing a displaced tooth
• Splinting a loose tooth to neighboring teeth
• Replanting a knocked-out permanent tooth
• Providing root canal treatment when the dental pulp is damaged
• Repairing or replacing a dental restoration
• Treating cuts to the gums or oral tissue
• Removing a tooth that cannot be predictably restored
• Referring the patient to an endodontist, oral surgeon, physician, or hospital

The immediate goals are to control pain and bleeding, stabilize damaged structures, protect the natural teeth, and reduce the risk of complications.

Follow-Up Care After Dental Trauma

An injured tooth may require monitoring for weeks, months, or longer. Problems can develop even when discomfort improves quickly.

Follow-up care may include:

• Repeat dental examinations
• Additional dental imaging
• Monitoring tooth color and sensitivity
• Checking the stability of a splinted tooth
• Evaluating the surrounding gums and bone
• Testing the health of the dental pulp
• Providing restorative or root canal treatment when necessary

Contact the dentist if the injured tooth develops new pain, swelling, drainage, discoloration, looseness, or sensitivity.

Possible Delayed Complications

Some consequences of dental trauma do not appear immediately.

Possible delayed complications include:

• Inflammation or infection inside the tooth
• Tooth discoloration
• Root resorption
• Loss of supporting bone
• Gum recession
• Persistent looseness
• Abscess formation
• Interrupted tooth development in children
• Loss of the injured tooth

Attending recommended follow-up appointments gives the dentist an opportunity to identify changes before they become more extensive.

Preventing Sports-Related Dental Injuries

Athletic activities are a common source of injuries to the teeth, lips, cheeks, and jaw.

Protective measures include:

• Wearing a properly fitted mouthguard
• Using helmets and face protection required for the sport
• Replacing a mouthguard that is worn, damaged, or too small
• Keeping the mouthguard clean and stored properly
• Avoiding removable dental appliances during contact sports unless instructed otherwise
• Keeping emergency dental contact information available

A custom-fitted mouthguard may provide improved retention, comfort, and protection compared with a poorly fitting appliance.

Frequently Asked Questions About Dental and Mouth Injuries

▸Does every dental injury require immediate care?
Significant dental trauma should be evaluated promptly, even when the tooth appears intact. Hidden damage may affect the root, pulp, socket, supporting bone, or neighboring teeth.

▸What should I do with a broken piece of tooth?
Save the fragment in a clean container and bring it to the dentist. Do not scrub it or attempt to glue it back onto the tooth.

▸Should I go to a dentist or emergency room after a mouth injury?
A dentist generally treats broken, loose, displaced, or knocked-out teeth. Go to the emergency room for loss of consciousness, uncontrolled bleeding, severe facial trauma, breathing difficulty, or symptoms of a serious head or neck injury.

▸Can a loose permanent tooth tighten again?
Some injured teeth may stabilize with prompt treatment and professional monitoring. Do not repeatedly move the tooth or chew with it. Contact a dentist immediately.

▸Should a knocked-out baby tooth be put back into place?
No. A knocked-out primary tooth should not be replanted because doing so may damage the developing permanent tooth beneath it.

▸Why does an injured tooth need follow-up if it no longer hurts?
Pain can improve even when the pulp, root, or supporting tissue has been damaged. Follow-up examinations help identify infection, discoloration, root changes, and other delayed complications.
