Pressure, tightness, and sensitive on gum area where I had my dental crown placed 4 days ago. Is this normal? (photo)

I had a dental implant surgery on August 31, 2018. Everything went well with healing process and the abundent . Then on March 12, 2019, dentist placed crown 4 days ago. It doesn’t hurt when I chew gum, food etc. but it feels pressure, tightness, the gum is sentive achy . Is it normal to feel all that after 4 days of having placed crown?
