Dental problems in a ferret are similar to those in dogs and cats and they can even suffer from orthodontic conditions.
Soft foods can cause tooth decay and require a visit to the vet for a clean. However remember that to clean a ferret’s teeth, the vet has to anesthetize the animal and that might cause problems.
I heard of 3 ferrets dying after having their teeth cleaned here in Western Australia. It could be that they had underlying problems which the vet was not aware of before putting them under and the anesthetic caused the problem to flare up.
