Molar gum bleeding
Bleeding beside a molar commonly reflects inflamed gum, trapped food, trauma, or infection and needs an examination if it persists.
The short answer
Bleeding around a molar most often comes from inflamed gum caused by plaque or trapped food, but trauma, a partially erupted wisdom tooth, or infection can also be responsible. The source is identified by examining the gum pocket, tooth surface, and nearby tissues.
Why is cleaning around molars sometimes difficult?
The gum around a back tooth can be difficult to brush and floss, allowing bacterial plaque to collect at the gum margin. A wisdom tooth under a gum flap can also trap debris in a pocket called a pericoronal space.
How should you clean around a bleeding molar gum?
Brush gently with fluoride toothpaste and clean between the molars with floss or an interdental brush. A dentist may remove calculus, flush a gum pocket, treat decay, or address a wisdom tooth according to the examination findings.
When should recurring molar gum bleeding be checked?
Arrange care if bleeding returns, the gum is swollen, chewing hurts, or food repeatedly lodges beside the molar. Seek urgent help for facial swelling, fever, difficulty opening the mouth, or trouble swallowing.
What should you ask about the source of bleeding?
Ask whether the bleeding is from gum inflammation, decay, a cracked tooth, or a wisdom-tooth flap. Ask whether you need a professional cleaning, a filling, periodontal treatment, or imaging.
Frequently asked questions
Should I stop brushing a bleeding gum?
No. Brush gently around it and clean the area, unless a clinician gives different instructions.
Can a cavity make the gum bleed?
Yes. Decay, a broken filling, or a crack can irritate nearby gum and may cause pain with chewing.
