Occasionally we see congenital or genetic dental conditions such as invagination folds of enamel or malocclusion in large felids.
The enamel defects allow bacterial invasion of the pulp chambers and eventually cause pulp necrosis at a relatively early age and associated abscess intra and extra-orally. The only treatment possible is extraction of the tooth or teeth in question.
