(1) If it is a vital pulp tooth (the tooth has not been treated with root canal before restoration), it is normal to have occlusal pain about one week after making porcelain teeth. Because in the process of tooth preparation and bonding, it is likely to stimulate the pulp, so that the pulp is in a state of temporary congestion, which can be restored. Try not to bite with that tooth during this time, and observe for a week to see if you can get better gradually. If it doesn't improve all the time, it will get worse, such as spontaneous pain (sudden pain without any stimulation), night pain (more severe pain at night than during the day), radiation pain (more diffuse pain range), persistent pain during cold and hot stimulation, or severe occlusal pain, suggesting that there is inflammation in the pulp or root tip, and it is necessary to go to the hospital for root canal treatment.

(2) If it is a dead pulp tooth (the tooth has been treated with root canal before the crown), it may be that the root canal treatment is not perfect after the porcelain tooth is made. You should go to the hospital to take a film to see if the filling is perfect, if there is any shadow at the root tip, and if there is any fistula in the gums.

(3) In addition, fixed-point occlusal pain may also be caused by high occlusion and periodontal ligament trauma. If this is the case, go to the hospital to check with bite paper and adjust the high point of grinding.

In short, I suggest you observe first. If you don't get better all the time, go to the hospital for examination, preferably to a regular hospital. If it is a problem that the doctor has treated before, let him improve his treatment. I wish you a speedy recovery.
