It's a cheek bite or any type of injury by any solid food..

That is called cheekbite .. accidental biting of inside mouth skin by your teeth. It will be ok in a few days

A sudden red spot in the mouth without pain or burning is most often due to local irritation, minor trauma, inflammation, or a healing ulcer. Erythroplakia is rare, usually persistent, and does not appear suddenly in a day. Avoid spicy foods, smoking, and alcohol, and maintain good oral hygiene. If the red area does not resolve within 10–14 days, increases in size, or develops symptoms, please consult an oral medicine specialist for examination.

No sir It looks like you bit that area. It must have come between ur teeth while eating. If in case u start having pain or burning sensation then it needs to be further evaluated

Looks like a traumatic red patch from cheek biting or friction, not erythroplakia. Usually heals on its own in 7–10 days. Avoid spicy food and repeated trauma. If it doesn’t improve in 2 weeks or increases, get it checked once.

Appears traumatic due to catching of cheek mucosa with teeth ! If doesn’t resolve in 2 weeks no harm in getting it checked once .
