This is one of those cases that doesn’t make any sense. 7 years on a cracked tooth with probing to the apex… probings adjacent to the cracks. We put him in meds for a couple months, the probings resolved. Then we put a core in and let him sit for another 3-4 months. He came back for the other side yesterday, with a necrotic molar with probings. He’s weighing his options, but still, I’m not optimistic.
