Yes we agree. The symptoms sound like those of a dying tooth and most likely root canal/s will be needed. Best to seek treatment.
They do need attention. If they are restorable they will most likely need root canals and crowns. Especially if they are hurting to temperature. If you do not seek treatment, the pain will most likely escalate so sooner is better than later. But the first step is to get in and have the teeth evaluated.
