Swelling on the roof of the mouth may be due to several potential causes, most of which will resolve with minimal treatment. In less common cases, the swelling may be due to a more serious condition.
Other symptoms may accompany the swelling, including:
- blisters or other sores
- dry mouth
- muscle spasms
- pain or discomfort
Read on to learn about the possible causes of swelling on the roof of the mouth.
Causes
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
3. Dehydration
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.
In most cases, a person can treat a swollen roof of the mouth at home or wait for it to heal on its own. Common injuries, such as a burn from a hot drink, will typically heal within a few days.
Cold sores or canker sores usually go away on their own. In some cases, a person may wish to use medications to help reduce the frequency or severity of cold sores.
In cases of dehydration or electrolyte imbalance, people can increase their liquid intake. It is best to drink non-alcoholic beverages, such as water or herbal tea.
If electrolytes are too low, a person may consider drinking a sports drink or juice to help restore the balance.
In cases where a person has an underlying condition, they should seek medical help from a doctor. Treatment options for cancer can include surgery, radiation, or chemotherapy.
When to see a doctor
Though most causes of swelling on the roof of the mouth do not require medical intervention, a person should speak to a doctor in some instances.
Some reasons to see a doctor include:
- pain that does not go away with over-the-counter medications
- unexplained swelling or swelling that lasts longer than a week
- swelling that is accompanied by other symptoms
In most cases, swelling on the roof of the mouth should not be a cause for concern. Typically, a person should see full recovery within a few days to a week.
