To treat and heal a busted lip, immediately apply pressure with a bandage or clean cloth for several minutes to stop any bleeding, according to the University of Rochester Medical Center. Wash the wound gently with soap and water to remove dirt, and apply an antiseptic lotion or cream.
When handling the lip, make sure hands are washed and free from germs, and avoid blowing on the lip wound as germs can grow, according to the University of Rochester Medical Center. Keep the lip area clean and dry, and continue to apply antiseptic lotion and ice to the wound every two hours for the first 24 hours as needed. When outdoors, use a sunscreen on the lips to avoid cracking, drying or burning as this increases the chances of a scar forming.
If the lip bleeds on the inside of the mouth, rinse out the mouth with cool water to remove dirt, and inspect the area to determine if a physician should be consulted or if stitches are needed for deep cuts, according to the University of Rochester Medical Center. Consult a physician if the lip wound is deeper or longer than 1/2 inch or if bleeding does not stop after five to 10 minutes of direct pressure.
