I fell last night on my face and my bottom lip is extremely swollen and bruised. there is also a cut from my tooth puncturing my lip. what should i do?

Ice: After 4-8 hours, it is too late for stitches (not that these are always necessary). Get a tetanus shot within 72 hours if you are not current. Ice as needed (30 minutes max, off an hour) for comfort. Tylenol (acetaminophen) for pain. If you have a loose tooth or increasing pain or signs of concussion get seen today. Otherwise, rinse mouth with warm salt water 4 times/day and try to avoid getting food into the cut.

See doctor as: you may need stitches and this needs to be done within 24 hours of injury, also use ice.

Be seen: Sometimes a fall and cut like that may not require stitches, but it is very possible it may, so see someone right away so that the healing will not be jeopardized.

Get checked: I assume you're not bleeding and not in acute distress. If your PCP is not available to access your injury today, go to Urgent care or ER.

Trauma to the lip: is quite common. If not bleeding rinsing 4-6 times per day with warm salt water, NSAIDs OTC or Tylenol, (acetaminophen) and apply Ambesol. Small puncture wounds in the lip usually heal without any treatment other than home remedies.
