Hello sir!
From your history it seems to be a peri coronal infection. It is the inflammation of gum tissue surrounding the crown portion of a tooth. It usually affects the third molar- wisdom tooth. The dentist will examine the wisdom tooth and take x-ray to look at the alignment of your tooth and will design the treatment plan. The area should he cleaned thoroughly, any food debris should be removed and pus will be drained.
Next Steps
kindly visit your dentist as soon as possible
