Tooth implants

About 6/8 weeks ago I started the procedure of getting a couple of teeth implants. But ever since that has happened I’ve lost my sense of smell slightly and my right nostril is always blocked. I thought I had a cold and got a blocked nose but that wasn’t the case. It happened ever since I got the implants.

Has this happened to anyone? I’m thinking that when they put the implants in the dentist might have done something to my sinus, am i wrong. Any advice would be great!
