Hello ma'am,
Normally, the pain should perish within 2-3 days of completion of treatment.But, since you're referring to it as unbearable,the etiology can only be understood after seeing the x-ray .
Sometimes an improperly placed cap impinges on gums, which may also cause pain.
Next Steps
Visit a local dentist.Tell him your worries and plan a solution.
