Cracked tooth bleeding when brushing
Bleeding near a cracked tooth can come from inflamed gum tissue, but the crack may also let bacteria reach deeper tissues and needs prompt assessment.
Why might a cracked tooth bleed when you brush?
Bleeding near a cracked tooth can come from inflamed gum tissue, but the crack may also let bacteria reach deeper tissues and needs prompt assessment.
How can a crack affect the gum and deeper tooth tissues?
A crack can trap plaque at the gum margin or create a sharp edge that injures the gingiva; a deeper crack can cause pain on biting, temperature sensitivity, or pulp inflammation.
What can you do while the cracked tooth is being assessed?
Bleeding does not show how far the crack extends, so visual inspection alone cannot determine whether bonding, a crown, root canal treatment, or extraction is needed.
Frequently asked questions

What information should I bring?
Note when it began, what triggers it, where it is, what makes it better or worse, and any swelling, bleeding, trauma, or medicines.
