I got a reply to a job I applied for!!!

I got a reply to a job I applied for!!! I applied for a dentist reception job awhile ago and never heard back. I felt discouraged and super unqualified because I know very little about dentist work and that I have a stutter. But I got an email this morning saying that their other candidate fell through and they would like to interview me! I’m so excited but nervous about my stutter hindering me from getting the job. Any tips for the interview position and/or about doing a receptionist type job with a stutter. All help would be very appreciated!
