Conclusion
Cutting on the gum can result from a fall, injury from contact sport, or sharp objects put in the mouth. Most cases of gum cuts are mild and tend to resolve on their own with some home remedies. However, they can also appear severe, causing more pain and complications. See your doctor immediately if the pain or bleeding on your gum persists.
