Tooth decay treatment

The groom went to the dentist because his tooth was hurting too much~

Someone else said that one side was broken, but my husband said it wasn't that person, but someone who was in pain, so I examined that person and did nerve treatment.

But I'm curious... I completed the root canal treatment when I was in the province, and

Now I need to put a crown on the treated tooth, but since I am coming from the countryside to the city, I have to go to a different dental clinic to do the crown. Should I get the treatment and have it crowned quickly? My husband has more free time in winter, so he plans to get the crown done then. Is it okay to wait a while after the treatment before placing the crown?
