This swelling in Zues's mouth could be due to a dental problem, trauma to his mouth, or an allergic reaction. Because swelling of the mouth can progress to affect his breathing, I would monitor him for now, and take him into a vet immediately if he starts to have difficulty breathing. Otherwise, I would take him into the vet first thing in the morning to have his mouth examined, diagnosed, and treated.
