Soft-tissue injuries to the tongue, cheeks, gums, or lips can cause bleeding. To control the bleeding, rinse your mouth with a mild salt-water solution. Apply pressure to the bleeding site using moistened gauze or a tea bag for 15 to 20 minutes. Holding a cold compress against the affected area can help control bleeding and alleviate pain. If bleeding persists, see the experienced team at Metro Decatur Dental Group promptly for professional care.
