Beardie lost a scale on his beard

[MillyMoose7]

Hi I'm completely new to this site and cant find any answers. My beardie has attacked himself in the mirror what seems to be 1 too many times and has lost his centre scale just below his mouth. It looks like a cut sort of thing, I'm worried and we dont know if we can get to a vet during quarantine. I have a photo if you need to help...
I'm really worried any help would be appreciated.

My first priority would be to keep it from getting infected. I would apply neosporin on it with a cotton swab to make sure to keep it from getting dirty. I would also try to get an appointment as soon as you can.
