[|Human|] Hi, may I a 35yr old male, today I noticed that I had red patch of blood hanging on the side of the roof of my mouth like big & long blister with blood in it. It was not painful so I used a toothbrush to bust it. It left painless pink spot. What could it be?
[|AI|]  Hello, I suspect that the most likely cause is trauma. This can include hard foods, exposure to hot temperatures, or habits. I suggest that you monitor the area. Rinse with warm salt water, avoid irritants, avoid acidic and spicy foods, and stick to a soft diet to assist healing. If your tissue is deny Chat Doctor.  If you have repeat episodes and can not associate the occurrence with a trigger, schedule a visit with your dentist for a clinical evaluation. Systemic factors may need evaluation with blood tests. Your medical and dental history will need to be reviewed as well. Thank you for your inquiry. I hope the area will continue to heal on its own.
