Root canal & Crowns

I’ve never had a root canal or crowns before so I don’t know anything. I just got my root canals done barely a month ago now. I got 5 root canals. I have three permanent crowns put on about a week ago on my right side. Is some sensitivity normal to have at this point ? I feel it only on my top one and only when I’m eating sometimes, doesn’t last long.

Also on my left side I still have two temporary crowns, is it okay to have them for a little bit over two months ? That’s around the time I think my permanent crowns will be ready for that side.

Thanks in advance.
