A fall, sports collision or bite on something hard can damage a tooth in seconds. What you do next matters, but the correct response depends on whether the tooth is chipped, displaced or completely knocked out. If you are dealing with a broken or knocked-out tooth in Mississauga, protect the area, locate any tooth fragments and contact a dental office promptly for instructions.

First, check for injuries beyond the tooth

Look for heavy bleeding, a deep facial cut, loss of consciousness, trouble breathing or a suspected jaw injury. These signs may require emergency medical care rather than a dental visit alone. If the injury appears limited to the teeth and mouth, rinse gently with clean water and use light pressure with clean gauze if there is bleeding.

If a permanent tooth is knocked out

Pick up the tooth by the crown—the part normally visible in the mouth—not by the root. If it is dirty, rinse it briefly and gently. Do not scrub it, remove attached tissue or wrap it in a dry tissue. If the tooth can be placed back in its socket without force, keep it there while obtaining urgent dental care. Otherwise, keep it moist in milk or an appropriate tooth-preservation product and call a dentist immediately. A knocked-out baby tooth should not be placed back into the socket because doing so could harm the developing permanent tooth.

If the tooth is chipped or broken

Save any pieces you can find and bring them to the appointment. Rinse your mouth gently, avoid chewing on the injured side and place a cold compress against the outside of the face if swelling develops. A small chip may feel like a rough edge, while a deeper fracture can expose sensitive inner tooth structure and cause pain with air, pressure or temperature.

Do not place aspirin directly on the tooth or gum. Avoid trying to glue a fragment in place or filing a sharp edge at home. A dentist needs to assess how far the damage extends and whether the tooth root, nerve or surrounding bone is involved.

Why prompt assessment is important

Dental trauma is not always as simple as it looks. A tooth can be cracked below the gumline, loosened in its socket or accompanied by damage to nearby teeth. An examination and, when appropriate, dental imaging can help the dentist decide whether the tooth should be smoothed, bonded, restored, stabilized or treated another way.

Be ready when you call

Tell the dental team when the accident happened, whether the tooth is permanent or a baby tooth, whether bleeding has stopped and where the tooth or fragment is being stored. These details help the office advise you on timing and next steps.
