My right cheek is swollen but no tooth pain. possibly a cold in my cheek? went to the dentist few months ago no cavities.

Parotid gland: Most likely it is a parotid gland issue. There is a duct inside your mouth next to the back top teeth which releases saliva from the parotid gland in your cheek. If it gets blocked, your cheek may swell. This happens more at mealtime, as your salivary flow increases. You may also have a parotid gland infection. Best to see your Oral Surgeon to check, as they would be the one to treat it. Good Luck

Common occurrence: Common swollen cheek causes: infection, trauma, allergy, lymph nodes and dental. I think you need an examination and tests by your doctor.
