Lots of dentists have closed shop for now because most dental work is not necessarily an "urgent" problem that requires immediate or emergency care, so they're trying to reduce risk of infecting patients since most things they do are non-essential and there aren't enough "emergency" cases to warrant staying open. Fortunately, though, oral surgeons *are* open because they are considered essential and offer emergency services. So, I think that an oral surgeon is a good start if things go downhill quickly.
