There is deep caries in your lower right second premolar, and also in the 2 nd lower molar, where there is impacted tooth. If that is the impacted tooth which you got extracted, then the pain in jaw might be the reason for the traumatic extraction. If not extracted yet, that is the reason for jaw pain.
