6 Possible Causes for Blisters in Mouth and Solutions

1. Cold sores

Cold sores are also known as fever blisters. They are caused by the herpes simplex virus and can appear as red, fluid-filled blisters. Cold sores usually occur on the lips, around the mouth. In rare cases, they can be found in the inside of the mouth, on the fingers or in the nose. Despite the name, you can’t get cold sores from colds. But several factors, such as colds and fevers can trigger the condition.

Cold sores can last for two or three weeks and then go away on their own. But, the sores or blisters are contagious. They can spread from person to person via close contact, such as kissing or sharing utensils. OTC creams or ointments can help reduce pain and discomfort and speed up the healing. Prosurx is one of the best creams for cold sores. It’s made with tea tree, lemon balm, aloe vera, vitamin E and more. These ingredients are all safe, natural and antiviral. Thus, applying Prosurx twice to three times a day can be very effective.

Blisters in mouth are usually caused by HSV-1. But sometimes, HSV-2 can lead to the condition too. This happens mostly through sexual contact. If you have oral sex with someone who has genital herpes, you will get oral herpes. In the disease, people will have blisters in the mouth or on the genitals.
