I am curious about how to care for my implant after the procedure.

My groom recently got an implant, and I am curious about how to take care of it afterward. I hear that many young people are getting implants these days, so I was quite worried before doing it. It was quite difficult during the procedure, but now he is satisfied with the results. I also heard that post-care is very important after getting an implant, but I wonder if he can just eat and brush his teeth normally. Are there any foods he shouldn't eat or potential side effects? I think it would be helpful to know in advance. I would like to hear opinions from people who have had implants. I'm curious.
