- pain or discomfort
Read on to learn about the possible causes of swelling on the roof of the mouth.
A range of conditions can cause a swollen roof of the mouth, including:
1. Sores in the mouth
Most common mouth sores, such as canker sores and cold sores, will appear on the gums, cheeks, or lips. In some cases, they may appear on the roof of the mouth.
Sores can cause pain, blisters, and swelling. Some people may notice pain or swelling before the sore appears.
2. Injury or trauma
One of the most common causes of swelling on the roof of the mouth is an injury or trauma. Some of the most common causes of trauma include:
- eating a hard food that may impact the roof of the mouth
- eating or drinking an extremely hot item
- a scratch from a sharp piece of food
Dehydration can cause swelling on the roof of the mouth. Dehydration can cause a dry mouth, which can result in swelling if a person does not take steps to relieve the condition.
Some common causes of dehydration and dry mouth include:
- excessive alcohol intake
- certain medications
- not drinking enough water
- excessive sweating, particularly on hot days or while exercising
A person with dehydration that causes an electrolyte imbalance may also feel especially weak or experience muscle spasms.
