Thanks for asking the query,
Swollen inflammed cheek can be because of allergic reactions, vitamin deficiencies, inflammation of the lymph nodes, parotid gland
, underlying dental infections, presence of cysts and tumors.
occurs due to immunological causes or nutritional deficiencies.
I would suggest you to visit to an Oral and Maxillofacial Surgeon and get the checkup done.
Take an x-ray if needed.
Avoid eating of hot and spicy foodstuffs.
Maintain a good oral hygiene
and use antiseptic mouthwash gargles twice daily.
Hope this helps out.
