Any cut inside the mouth usually bleeds heavily because of the rich supply of blood to the area.
Routinely using seat belts and car seats can reduce the risk of trauma as a result of car accidents.
If your lip is swollen or bruised, apply a cold compress. If there is bleeding, apply pressure with a clean cloth for at least five minutes. Using ice can help limit swelling, bleeding and discomfort. Wrap crushed ice in clean gauze or a clean piece of cloth and hold it on the area affected.
Certain injuries will require treatment by an oral surgeon or plastic surgeon. It is particularly important to have an experienced surgeon stitch cuts that cross the vermilion border. This is the line that forms the junction between the skin and the fleshy part of the lip. Experience is required to make sure this boundary heals correctly. Even a small irregularity will remain noticeable.
The doctor will first thoroughly clean the wound with lots of saline or a hydrogen peroxide rinse. Cleaning removes bacteria as well as foreign matter such as dirt that might have entered the wound. A betadine solution will then be applied to the area to disinfect it. Puncture wounds to the lip will then be closed from the inside out. Stitching all layers reduces the chance of scarring..
Small puncture wounds in the tongue usually heal without any treatment other than cleansing with antiseptic or hydrogen peroxide rinses. Large cuts may require stitches.
The mouth contains many bacteria. For this reason, an antibiotic often is prescribed after a cut to the lip or tongue to prevent infection.
If a tooth is loose or broken, visit your dentist.
