Treatment for Oral Blood Blisters
According to the World Journal of Stomatology review, treatment is often not necessary, as the blisters typically heal within two weeks on their own. It's also important to remember that these oral blood blisters are benign, meaning they are not cancerous or harmful to your health. Sometimes, they may reappear in different parts of the mouth, so if you notice frequent blister formation, it's a good idea to check in with your dental professional.
If a blister is particularly uncomfortable, your dental professional can help you control the pain. They will inspect the blister and might choose to prescribe an antibacterial mouthwash or anti-inflammatory medication to alleviate any discomfort and speed up the healing process, explains the World Journal of Stomatology review. Your dental professional may also recommend eating a soft diet to avoid further irritating the area. These treatments may help prevent an infection from developing after the blister has popped.
Most blood blisters go away on their own without any medical intervention — however, if you notice any abnormal symptoms, such as pus draining out of the blister, see your dental professional as soon as possible for an evaluation. They will thoroughly examine the affected area and make sure that it heals properly.
