Question: hello, i seem to get reoccurring blood blisters on the inside of my mouth. i have had an abscess on my gum which i had root canal, and blood blisters happened after that. i just had my crown fitted and now i have a blood blister. im wondering if the work on my tooth has cause the reoccurring blood blisters or if its some thing else. also it appears that one may have burst as i have loose skin on the inside of my mouth. thank you.

Please upload pictures.

Detailed Answer:


A blood blister can be commonly due to injury to the mucosa.

But to advise you better I would like to know the exact location inside the mouth where you are getting blood blisters?

Is it inner side of cheek?

Also has it started after crown placement?

Do you bite the area where you get blood blisters?

Please upload a picture for a more clear understanding.

Hope I have answered your query.

Take care
