[MO] Quick question about interview

Hi all. I had a telephone interview today with a recruiter. It went well and the site manager wants to meet with me Monday for an in person interview. I am perfectly fine with an interview Monday...actually I am thrilled. one problem though.

I am in the midst of waiting for my dentures to be finished. I have nine teeth for the next 3 weeks lol. This is bad timing for sure.

1. Do I pre-warn the manager via email that I'd love to interview however I might not look as professional as they would like ..or just show up with a huge gaping smile

or

2. Do I feign a cold and wear a mask to cover my mouth?

Any other suggestions would be appreciated!
