“Base Narrow Canines” are a common issue among smaller breed dogs, is considered a congenital defect, and is most often identified first with the baby teeth. ” Base narrow”refers to when the lower canine teeth are angled inward, pushing against the dog’s palate (roof of the mouth). Baby base narrow canines can be extracted with little difficulty, allowing the soft palate to heal from trauma caused by the teeth and allowing the adult teeth to erupt in the proper position. Any palate contact can be quite painful so extractions of the baby teeth are recommended. Dogs can be very stoic regarding pain so it is unlikely that you will see any outward signs of discomfort. Most will generally eat and remain active even with mouth pain. It is highly recommended that any baby base narrow teeth be extracted quickly to give the adult teeth enough room to erupt in a good position. As the adult teeth erupt to the inside of the baby teeth, if baby teeth are base narrow, without intervention, the adult teeth are likely to be as well, and adult base narrows can be much harder (and much more costly) to fix. Removing adult canines is not a viable option as the adult canine teeth provide the primary structure support for the lower jaw. Adult base narrows often require a specialist procedure and can involve root canals or crown amputations. Removing base narrow baby teeth will generally allow the adult teeth room to grow into acceptable/desirable positions. Orthodontic problems are considered a hereditary issue and spaying/neutering is recommended.
