Dentistry Case #10

0 Comments Posted by tcahvet in Dentistry on Wednesday, December 7th, 2011.

We had a very interesting case recently that highlights abnormal growth and formation of the teeth. “Coco”, is a 1.5 year old Pomeranian. She had a small congenital umbilical hernia but no other health problems. When she was in to have a routine dental cleaning, we noted she had several retained deciduous teeth.

Retained Deciduous Tooth

The second tooth from the left is the deciduous of the third tooth. It was never fully expelled.

Radiographs revealed the full extent of the problem. She had very few adult teeth and most of her teeth were slowly degrading deciduous teeth. The retention of these teeth caused her few adult teeth to come in at abnormal angles and two of them hadn’t erupted at all.

These teeth are, from left, adult canine tooth, deciduous canine tooth, adult unerupted first premolar, 2 deciduous premolars, deciduous first molar, adult first molar.

At this cleaning we removed the two deciduous teeth that were loose and made a plan to remove the others. We plan to remove those affecting the malocclusion of the adult teeth first, then those starting to dissolve and lastly those that are not presently causing a problem.

Severe crowding of lower jaw due to retained deciduous teeth.

Because the deciduous teeth have thin enamel they are more prone to cavities and breakage. When we are done this dog will have only half of the normal number of teeth for a dog.
