Skye, a 5-month-old Border Collie mix, came to see us because her deciduous (aka baby) canine teeth were retained, meaning they didn't fall out when they were supposed to. Her primary care vet noticed the problem and was worried about the baby canines affecting the normal eruption of the adult canines. Her lower canines (both the deciduous and permanent teeth) were also pushing into the roof of her mouth, which was painful. Skye's lower canine teeth are linguoverted (commonly called "base narrow"), meaning they point more straight up and down instead of angling out to the sides like they should. Since the adult lower canine teeth erupt lingually (on the inside) of the baby teeth, the baby teeth were preventing the adult teeth from erupting normally. If the deciduous canines were not removed, the adult teeth would continue to erupt towards the tongue. Skye had all four baby canine teeth extracted. This will give the adult teeth room to grown in properly. In some cases, the adult canines may still erupt linguoverted and continue to cause trauma to the palate. If this is the case, Skye will require more treatment. Treatment options for linguoverted adult canines include a type of orthodontic appliance known as an "inclined plane", which helps tip the lower canines into the right position, or a procedure called crown reduction where the teeth are shortened so they're not causing damage or pain. If crown reduction is performed, it must be accompanied by vital pulp treatment, which keeps the tooth alive and healthy after it is cut short.
Skye recovered well from her procedure, and we will see her back in a few weeks to reassess her adult teeth. Hopefully they grow in normally, but if not, with the right treatment Skye will still grow up to be a happy and healthy girl with a comfortable and functional mouth!
