Based on the history and photographs this is localized traumatic ulcer/hematoma (bruise-like lesion.A brown center with a surrounding red halo can occur due to minor trauma or a healing blood clot beneath the mucosa, even if cheek biting is not noticed.

Based on the photograph, this appears to be a localized area of inflammation/trauma with a healing ulcer or minor bruise-like lesion on the cheek mucosa. Such patches can occur due to accidental cheek biting, irritation from a sharp tooth edge, hot food injury, or other minor trauma, even when the patient is not aware of it. A definitive diagnosis cannot be made from a photograph alone. If the patch is painless and starts reducing in size over the next 1–2 weeks, it is usually a reassuring sign. However, if it persists beyond 2 weeks, increases in size, becomes painful, bleeds, or similar lesions appear elsewhere in the mouth, an in-person oral examination is recommended.

Hello This looks like the patch due to post ulcer Please wait and observe for a few days at least 10 days and if it doesn’t resolve then go for physical examination

Hello, Please do not panic. Based on your description, these red patches may be related to local irritation, a minor traumatic ulcer, inflammation of the cheek mucosa, or other benign oral conditions. It is not possible to make a definitive diagnosis from a photograph alone. The fact that the lesions have been present for only 4 days is somewhat reassuring, as many inflammatory or traumatic lesions resolve on their own within 1–2 weeks. I would recommend: • Maintaining good oral hygiene. • Avoiding spicy, acidic, and very hot foods. • Staying well hydrated. • Avoiding repeated touching or checking of the area. If the patches increase in size, become painful, develop ulceration, bleed, or persist beyond 2 weeks, you should undergo a clinical examination by an Oral Medicine Specialist or Oral and Maxillofacial Surgeon. Most oral mucosal lesions of recent onset are not serious, but a direct examination is necessary for an accurate diagnosis. Regards, Dr. Mohit Gautam BDS, MDS (Endodontist)

Hello . Kindly consult with your nearest dentist for further examination

This patch occurs due to burn after eating something very hot  You mentioned you don't have medicine and allergy history If this is single it will resolve on its own in a few days And if this hurt you more you can apply gel Like (dolo gel ct, rexidiene m- forte gel) on the affected area with clean finger And if present in your mouth more than 1 than visit your dentist

Hello Mam , i understand your concern. May i know your medical history ? Are you under any medication ? If not , you have these patches all around the mouth or just in one restricted area? Next we need to know it is painful or is asymptomatic. Lastly a dentist will palpate the lesion and check if it is hard or flexible . You need not worried but i would suggest to visit nearby Dentist for a better Clinical analysis

The patches seems like purpura or post ulcer indentation , could please elucidate your medical history or any other medical conditions
