Hey. As I can notice that you have an abcess associated with your premolar area, I would request you to kindly get a X-ray done as soon as you can else this may lead to further complications. There could be two reasons for the abcess formation which could either be due to a carious involvement reaching all the way down to your root end causing an infection or a periodontal infection. Deep cleaning only may not be the solution. Kindly get a X ray done. This may require urgent root canal treatment. If possible please upload your x ray here.
