Roof of Mouth Swollen

The roof of your mouth (palate) can become swollen for a number of reasons. Allergic reactions, irritants, injury, and infections are common contributors to mouth pain, but there are a number of home treatments you can use when you find your palate swollen.

What Causes My Roof of Mouth Swollen?

Most sufferers of roof of mouth pain will find that the underlying cause is unknown. However, in some cases, swelling is attributed to infections, physical trauma, allergies, or even larger systemic diseases affecting the body. Typically, conditions that affect the amount of saliva your mouth produces will affect mouth irritation.

1. Infections

You may find your roof of mouth swollen due to a virus or other infection.

  • The herpes simplex virus, which causes mouth sores, is typical of the mouth area. The chickenpox virus, varicella-zoster, can cause recurring sores on the side of the mouth that are painful both when raw and healing.
  • Bacterial infections due to tooth decay and poor hygiene will contribute to swelling and soreness.
  • People with AIDS may sometimes experience painful irritation in the roof of the mouth due to overproduction of candida yeast, and syphilis can cause painful sores that may be contagious.

2. Physical Trauma

Injuring the inside of the mouth will cause swelling and pain in the area. This can be caused by accidentally biting a cheek or be due to orthodontic or dental procedures. Foods like citrus and other acidic items or strong flavors like cinnamon can cause the roof of the mouth to hurt, and cleaning properties in certain dental care products can also contribute to injury or soreness.

3. Smoking and Tobacco Use

Using tobacco can contribute to mouth pain, and like an irritation from food or chemicals, is due in part to the toxic materials they are made from. Using tobacco products also contributes to roof of mouth pain by complicating other conditions, such as drying of the mouth, an imbalance in pH, and reducing the body’s immune properties.

4. Medical Treatments

Mouth pain can be a common side effect of many medical treatments. Patients undergoing chemotherapy or other radiation treatments may develop dry mouth and mouth pain.

5. Systemic Illness

There are a number of systemic conditions that contribute to mouth pain and complications in other areas of the body.

  • Rare skin diseases may cause blistering or other painful conditions.
  • More common illnesses, such as Irritable Bowel Syndrome (IBS) or Celiac Disease also affect sufferers with mouth pain.
  • Severe allergic reactions and inflammatory illnesses can also attribute to roof of mouth swelling and pain.
