Cuts and Wounds of the Mouth and Lips
Children often get minor cuts, wounds, and lacerations to the mouth and lips while playing, climbing, or participating in sports activities. Most of these injuries can be handled at home with simple first-aid treatment. The gums, tongue, and lips have a rich blood supply. When cuts happen, these areas may bleed a lot.
First aid for superficial cuts and wounds
Recommendations for taking care of cuts and wounds include the following:
Calm your child and let him or her know you can help.
Apply pressure with a clean cloth or bandage for several minutes to stop bleeding.
Wash your hands well.
If the wound is on the lips or outside area of the mouth, wash it well with soap and water. Do not scrub the wound. Remove any dirt particles from the area and let the water from the faucet run over it for several minutes. A dirty cut or scrape that is not well cleaned can cause scarring:
Apply an antiseptic lotion or cream.
Give your child an ice pop or ice cube to suck on to help reduce bleeding and swelling.
Check the area each day and keep it clean and dry.
Avoid blowing on the wound, as this can cause germs to grow.
Use a sunscreen (sun protection factor, or SPF, at least 15 or greater) on healed cuts and wounds to help prevent scarring.
If the wound is inside the mouth, rinse the area well with cool water for several minutes. Remove any dirt particles from the area:
Even small cuts on the lips may cause a noticeable difference in the border or outline of the lips. These wounds may need stitches to keep the borders even and reduce the possibility of scars. Cuts that happen in the corner of the mouth where the upper and lower lips come together have the potential for very severe bleeding.
Often cuts inside the mouth, even if they appear large, are left to heal spontaneously without the need for stitches.
Bruises, blisters, or swelling on the lips caused by trauma may be treated by sucking on ice pops or ice cubes or by applying a cold pack to the area every 1 to 2 hours for 10 to 15 minutes for the first 24 hours.
When should I call my child's healthcare provider?
Specific treatment for cuts and wounds of the mouth that need more than minor treatment at home will be discussed with you by your child's healthcare provider. In general, call your child's provider for cuts and wounds of the mouth that are:
Bleeding and do not stop after 5 to10 minutes of direct pressure. If the bleeding is profuse, hold pressure for 5 to 10 minutes without stopping to look at the cut. If the cloth becomes soaked with blood, put a new cloth on top of the old one. Do not lift the original cloth. Keep in mind that facial wounds often bleed heavily, even under normal circumstances. Call the healthcare provider if a wound or cut does not stop bleeding after 10 minutes.
Also call if the wound is:
Deep or longer than 1/2 inch
Large and on the face
Caused by a puncture wound or dirty or rusty object
Embedded with debris, such as dirt, stones, or gravel
Ragged or have separated edges
Caused by an animal or human bite
Excessively painful or if you suspect a fracture or head or bone injury
Showing signs of infection, such as increased warmth, redness, swelling, or drainage
A cut that goes from the inside of the mouth to the outside ("through and through")
Also call your child's healthcare provider if:
Your child has not had a tetanus shot within the past 5 years, or if you are unsure when your child's last tetanus shot was given.
You are concerned about the wound or have any questions.
Preventing mouth injuries
The following are a few guidelines to use for preventing mouth injuries in children:
Teach your child never to walk or run while holding an object in his or her mouth.
Teach your child not to suck or chew on hard, sharp, or pointed objects, such as pencils.
Have your child wear a mouthguard for sports activities that could cause injury.
