The roof of the mouth is made of the soft and hard palate. While the hard palate is made up of a flat bony parcel, the soft palate is made up of soft tissue. These are thin and delicate which makes it sensitive and quite susceptible to damage. As a result, a swollen roof of mouth is a common issue. While this is normally of great concern to the victims, swelling in the palate can result from a number of things most of which only bring discomfort. Below we explore the causes, treatments and when to see a doctor over a roof of mouth swelling.


In most cases, the causes of a swollen roof of mouth are not of medical concern. This is because swelling could result from a burn caused by a steaming hot cup of coffee, a bruise from munching on potato chips or even spicy food. However, a swelling that lasts too long may be indicative of palate cancer. Below we delve into the various causes.

Allergic Reactions

When the roof of the mouth gets into contact with a substance it deems an allergen, the area reacts by producing antihistamines. Allergic reactions to mouthwash and toothpaste can cause symptoms in the mouth. In other cases, food could be the culprit.

When a reaction occurs, it may result in symptoms such as swelling, inflammation, irritation and a runny nose. In severe allergic reactions, the patient may experience vomiting, diarrhea, wheezing and shortness of breath. In case it gets to this, see a doctor immediately.

Physical Injury

When the palate is subjected to physical trauma, an injury will result. This could occur during dental procedures, using toothpicks as well as getting pricked by something sharp that could be in food such as a fish bone, sharp potato chips and the like. A fall could also see you injuring your roof of mouth thus swelling.

Burns while Eating

Mouth burns while eating can result from a number of things. These include ingesting hot substances. A hot cup of tea or coffee can have a scalding effect on the soft palate resulting in burns and swelling. Other things that could cause burns and swelling are spicy and acidic foods.

Peppers, lemons, cinnamon and other foods with strong flavors could irritate the mouth to an extent of blistering it. This is more so for persons who suffer oral hypersensitivity. In such cases, the roof of the mouth will be red, hot, painful and swollen. To quell a burn, gaggle cold water immediately if happens to stop the palate from burning further.


Mouth infections can see the roof of the mouth swollen. These could either be bacterial or viral. Sinus infections, common colds, thrush as well as strep throat can all affect the palate since microorganisms in other areas can invade it. To strengthen the immune system and keep these infections minimal, eat foods rich in vitamins B and C.
