Hey ,
Since the right wisdom tooth was removed 7years back there are chances that the opposing tooth I.e the right upper posterior most teeth has supra-erupted and will be exerting pressure on the lower mucosa and can be the cause of pain … but this can be confirmed again on clinical examination ,also is the pain constant or seen intermittently on biting or chewing ??
Once we find the cause we can discuss about the treatment u
Next Steps
Clinical examination would give a proper view to your problem hence kindly visit the clinic when time permits
