@brack1 welcome to Mayo Clinic Connect. Salty crystals in the mouth must be difficult to manage. I added a link, about salivary stones, from JohnsHopkins Uni. You might take it to the dentist and see what he/she says.

It seems that there are many causes for stones so a visit to your doctor might be a good idea.
Can you give your doctor a call on Monday?
