Gum around crown bleeding
Bleeding around a crowned tooth commonly reflects gum inflammation from plaque, trapped cement, an overcontoured margin, or a problem beneath the crown.
Why is the gum around my crowned tooth bleeding?
Bleeding around a crowned tooth commonly reflects gum inflammation from plaque, trapped cement, an overcontoured margin, or a problem beneath the crown.
Where does the crown margin meet the gum?
The crown margin meets the prepared tooth near the gingival sulcus. Plaque or cement can irritate this tissue, while decay, a loose crown, a crack, or an ill-fitting margin can cause food retention or deeper disease.
How can I clean a bleeding crown margin gently?
Clean the margin with a soft brush and suitable floss threader or interdental brush without forcing it downward. A dentist may probe, take a radiograph, remove excess cement, adjust or replace the crown, or treat decay and gum disease.
When does bleeding around a crown need dental care?
Arrange care if bleeding persists, the crown feels loose, chewing hurts, or there is bad taste, swelling, pus, or worsening sensitivity. Facial swelling, fever, or difficulty swallowing needs urgent assessment.
What should my dentist investigate when a crown margin bleeds?
Ask whether the bleeding is from gum or tooth, whether the margin is sealed and accessible, and whether imaging or crown removal is needed.
Frequently asked questions
Can I floss around a crown?
Yes. Clean the contact and margin gently with a suitable interdental aid and avoid snapping floss into the gum.
Does bleeding mean replacement?
Not necessarily. The margin, tooth, and supporting gum must be assessed first.
