This oral benign tumor that is effecting the dental structure is known as an Odontoma. This was an incidental finding during a routine spay procedure and it affected teeth on both sides of the upper arcade in this specific case. The arrows above show the abnormal growth of the teeth because of the tumor. This dog was likely born with this malformation (aka congenital malformation) because she is only 6 months of age. The bone structure of the jaw may be affected so the dental procedure of removing these teeth and tumor would need to be completed at a dental specialty center with specialized equipment and dental radiography.
