Causes of Gum Blisters and Home Remedies for Treatment

Updated on October 15, 2014

Gum blisters or just an an accidental sore?

There are various medical conditions that may be attributed to the causes of gum blisters, or it could simply be something as simple as accidentally biting the inside of your mouth while chewing on food. However, if you experience gum blisters often and repeatedly, then the sores could indicate more serious health problems. It is recommended that you consult with a physician if this is the case.

Blisters are typically found on the cheeks, lips, tongue, gums and occasionally the more solid tissues of the mouth such as the roof and floor. They are generally very small in size, and surrounded by dark red. There are also a couple of rarer forms, including major aphthae and herpetiform ulcers.

Causes of gum blisters: parulus

One of the causes of gum blisters may be a condition which is clinically referred to as parulus.

  1. A parulus blister typically forms on the gums near an infected tooth. The decaying and infection within the tooth can cause the sensitive nerves in the area to die. The dead nerves can ooze out of the area.
  2. Considered by the body to be a toxin, the body will get rid of the dead nerves by letting them drain through the blisters. White blood cells, which are the human body's natural defenses against infections, will arrive around the area, making pus.
  3. The parulus forms when this pus bursts through the abscess.

Treating paralus: The issue can be kept at bay with good hygiene and taking care not to damage the gums with harsh toothbrush techniques. A parulus issue requires the help of a dentist to remove the dead tooth, as well as a root canal procedure to get rid of the infected root.

Other Causes of Gum Blisters

There are other causes of gum blisters as well, including herpes labialis. These are common cold sores which can occur around the gums, lips, and inner mouth. They are small and often painful sores, a result of the herpes simplex virus. The sores are extremely contagious and require over-the-counter topical treatment. If they are a chronic issue, a prescription for antiviral medicine may be necessary.

Crohn's Disease is also one of the causes of gum blisters. Although the disease is often determined by inflamed bowels, ulcers and blisters of the mouth can easily occur too. Swollen gums can accompany the symptoms, as well. The cause of Crohn's Disease is largely unclear, but can be aided by diet change and certain medicines.

Gum blisters can also be caused by:

  • Injuries to the mouth
  • Burns sustained from too-hot or spicy food can cause them
  • Accidental bites to the inside of the mouth
  • Harsh brushing
  • Orthodontic appliances which do not fit properly

Most blisters in and around the mouth will go away in time with little to no help. However, serious and chronic blister issues need to be examined by a medical practitioner in order to rule out the possibilities of serious underlying disorders.

Home Remedies for Mouth and Gum Blisters

While most gum blisters typically heal on their own, there is also a chronic and extremely painful type called recurrent apthous stomatitis, also known as just apthous ulcers. These blisters can be extremely painful. Luckily there are a few home remedies for mouth and gum blisters you can try to alleviate any discomfort and get rid of gum blisters.

Good oral hygiene
One of the home remedies for mouth and gum blisters is as simple as keeping up a good hygiene regimen. Brush teeth well and often, and use antibacterial mouthwashes frequently.

Foods to avoid
Avoid eating and drinking things that can agitate the blisters. These items include spicy foods, acidic foods such as citrus fruits, and items which are crunchy or have sharp edges. Alcohol and caffeine intake can also aggravate your blisters. If you must drink anything other than water, use a straw to keep the liquid from touching the sensitive spots.

Apply hydrogen peroxide.
This can help alleviate any discomfort and speed along the process of the gum blisters disappearing on their own. However, be sure to dilute it with water, and simply swish it around in your mouth, being careful not to swallow any.
