Bleeding swollen gums around one tooth
Bleeding and swelling around one tooth can come from plaque, trapped food, trauma, decay, or infection near that tooth.
The short answer
Bleeding and swelling around one tooth commonly reflect local gum inflammation, but trapped food, a deep cavity, a cracked tooth, or an abscess can also be responsible.
Why are the gums bleeding and swollen around one tooth?
The gum margin around a tooth contains small blood vessels that become fragile when inflamed. A dentist checks the pocket depth, tooth response to cold or tapping, decay, cracks, and the surrounding bone with appropriate imaging.
Why does inflammation make the gum bleed around one tooth?

How can you clean safely around the swollen tooth?
Gently brush and clean between the teeth without forcing floss into swollen tissue, and rinse away trapped food with water. Avoid repeatedly pressing the gum because mechanical trauma can prolong bleeding.
When should bleeding and swelling around one tooth be examined?
Book a dental examination when the change lasts, recurs, produces pus or a bad taste, or is accompanied by tooth pain or looseness. Facial swelling, fever, or difficulty swallowing calls for urgent assessment.
What should the dentist check around the affected tooth?
Ask whether the problem is in the gum or tooth, whether a pocket or cavity is present, what imaging is needed, and how to clean the area while it heals.
Frequently asked questions
Should I stop brushing there?
No. Use a soft brush gently at the gum edge unless a clinician has told you to avoid the area.
Why does it bleed when I touch it?
Inflamed gum tissue has increased sensitivity and can bleed with light mechanical contact.
