Swollen upper mouth, also known as mouth edema, is a condition characterized by the swelling of the tissues in the roof of the mouth, specifically the hard palate at the front and the soft palate at the back. This swelling can be caused by a variety of factors, with common causes including:
-
Sores in the mouth: Sores, such as canker sores or cold sores, can develop on the牙龈, cheeks, or roof of the mouth. These sores can cause pain, blisters, and swelling, sometimes even before the sores appear. Sores can also be caused by injury or trauma from eating hard foods or hot items, or from a scratch from a sharp piece of food. 2. Injury or trauma: An injury or trauma to the mouth, such as cuts by hard objects, eating hot foods that may impact the roof of the mouth, or scratches from sharp foods can also cause swelling on the roof of the mouth. 3. Dehydration: Dehydration can lead to swelling on the roof of the mouth due to a dry mouth caused by insufficient water intake. Dehydration can result from excessive alcohol consumption, certain medications, not drinking enough water, excessive sweating on hot days or while exercising, or illnesses that cause脱水 and electrolyte imbalance, which may lead to muscle spasms. 4. Mucoceles: A mucocele is a buildup of mucus that forms inside a lump that appears on the roof of the mouth, called a mucocele. Mucoceles are typically painless and occur after minor injuries, such as cuts on the roof of the mouth. Most mucoceles do not require treatment and may burst on their own. If a mucocele is particularly large or tends to recur, a doctor can safely drain it.

Squamous papillomas: Squamous papillomas, also known as human papillomavirus (HPV) warts, can appear on the roof of the mouth, tongue, or cheeks. These noncancerous growths do not typically cause pain but may cause irritation and pain if they become tangled or damaged. If squamous papillomas are discovered and diagnosed, they should be treated immediately by a healthcare professional, which may include surgery. 6. Underlying medical conditions: Rarely, a swollen upper mouth may be due to an underlying medical condition, such as oral cancer or viral hepatitis. Oral cancer is uncommon, with an estimated incidence rate of approximately 5 cases per 100,000 people in 2018. If a swollen upper mouth is caused by an underlying medical condition, it is important to seek immediate medical help from a doctor, who can provide appropriate treatment options based on the specific condition.
