Swollen upper mouth
A swollen area in the upper mouth can come from irritated mucosa, a dental infection, trauma, or a blocked salivary gland.
The short answer
A swollen area in the upper mouth can come from irritated mucosa, a dental infection, trauma, or a blocked salivary gland. The upper mouth includes the hard palate, soft palate, upper gum, teeth, and cheek-side tissues.

What is the direct answer?
What does this question mean?
The upper mouth includes the hard palate, soft palate, upper gum, teeth, and cheek-side tissues. Location, tenderness, ulceration, tooth symptoms, and how quickly swelling appeared help narrow the cause.
What can you do next?
Rinse gently with lukewarm water, avoid picking or burning the area, and keep brushing around it with a soft brush. Do not squeeze a lump or place aspirin on the tissue.
When should you seek dental care?
Book dental care promptly for swelling that persists, enlarges, or accompanies toothache, pus, fever, facial swelling, or difficulty opening the mouth. Emergency care is needed for trouble breathing or swallowing.
What should you ask the dentist?
Ask whether the swelling is in the palate, gum, tooth root, or salivary tissue, and whether an examination, dental radiograph, drainage, or other treatment is needed.
Frequently asked questions
Could this have more than one cause?
Yes. An examination distinguishes common irritation or inflammation from tooth, gum, appliance, or medical causes.
What information should I bring?
Bring a list of medicines, relevant health conditions, when the symptom began, and what makes it better or worse.
