A cut lip and a damaged tooth after a fall: which care do you need?
Check the person first, then the lip, then the tooth. Any loss of consciousness, confusion, vomiting, severe headache, a jaw that will not close normally, bleeding that does not stop after about ten minutes of firm pressure, a deep or gaping lip cut, or a cut through the lip border goes to emergency care first (call 911 or the nearest emergency department). A knocked-out adult tooth is then the most time-sensitive dental problem; a chipped or loosened tooth with controlled bleeding usually means calling a dentist promptly.
Step one: the person
If any of these apply, this is not a dental-office problem first: trouble breathing or swallowing, rapidly spreading swelling of the face or neck, fever with facial swelling, bleeding that will not stop, or a serious injury to the head or jaw. Call 911 or go to the nearest emergency department. Do not use the appointment request form for these.
Step two: the lip
| Lip finding | Care |
|---|---|
| Small cut, bleeding stops with pressure | Clean with water; cold compress; dentist can check for tooth fragments in the lip |
| Deep, gaping, or crossing the lip border; bleeding not stopping after 10 minutes | Emergency department; stitches may be needed |
| Cut inside the lip from a tooth | Check that no tooth fragment is embedded; the dentist may x-ray the lip |
Step three: the tooth
| Tooth finding | Care |
|---|---|
| Knocked out (adult tooth) | Handle by the crown; rinse briefly if dirty; reinsert if possible, or keep in milk or saliva; dental care within the hour (OHF) |
| Knocked out (baby tooth) | Do not reinsert; call the dentist |
| Pushed out of position or loose | Dentist the same day |
| Chipped | Keep the piece; dentist promptly; sooner if sensitive or a pink spot shows |
| Looks fine | Still have it checked; nerve injury can show later |
The American Dental Association's emergency guidance covers these injuries (ADA).
What changes the answer
Age (baby versus adult tooth); whether a tooth is missing and unaccounted for (could be inhaled; emergency department); tetanus status for dirty wounds; blood thinners; a mouthguard sport.
Follow-up
Injured teeth need scheduled checks for months, since the nerve can die later without pain. Tell the dentist exactly what happened.
Next step: Request a consultation or call (805) 565-5111. A request is not a confirmed appointment; the office confirms times during its listed hours (Monday to Thursday, 8 am to 5 pm, plus select Fridays).
Person-lip-tooth triage table
1. Person: unconscious, confused, vomiting, severe headache, jaw not closing → 911 / emergency department
2. Lip: bleeding not stopping after 10 minutes, deep or gaping, crossing the lip border → emergency department
3. Tooth:
| Finding | Do |
|---|---|
| Adult tooth out | Reinsert or milk; dentist within the hour |
| Loose or displaced | Dentist same day |
| Chipped | Keep piece; dentist promptly |
| Missing and not found | Emergency department (possible inhalation) |
