The bad news is that you are describing a tooth issue called odontoma. Normally due to trauma (many baby squirrels fall from the nest landing on their face and the dental issues from that can take many years to show up), the teeth begin growing large calcium deposits at the roots of the front teeth, and since the calcium is being directed there it is no longer working to keep the teeth growing out of the gums. The deposits will become larger and larger until they begin to interfere with the sinuses and breathing. Treatment involves removing the teeth, which is a difficult surgery.
That is the bad news. The good news is that the number one squirrel vet who at this point probably does a couple of these procedures a day now and who we have had people drive cross country to see, lives and practices in Port Orange FL.

It is possible you are looking at something else but either way, teeth require vet intervention. Call this practice.
