No, we are not talking about “Hollywood Smiles” and braces for pets. Orthodontic care in pets focuses on relieving teeth that are positioned incorrectly and causing pain. Orthodontic care in pets can take many forms, including acrylic appliances, brackets, elastics, and simple extractions. The typical arch wire appliances used in humans are almost never used.
One form of orthodontic care, called “interceptive orthodontics”, is employed when deciduous (baby) teeth are positioned incorrectly, or fail to be shed as the adult teeth erupt. (See the FAQ on “Double Teeth”) The presence of more than one tooth in the same place at the same time can lead to a painful malpositioning of the adult teeth. In some cases, early extraction of the baby teeth will allow the adult teeth to come in normally. To correct the problem, the entire root structure must be extracted. Some breeders will simply “clip” the baby teeth off with nail trimmers. This cruel practice is painful, leads to infection under the gum line, and rarely helps the permanent teeth position themselves normally. Clipping off the baby teeth is not humane, and is discouraged.

Retained baby teeth causing adult tooth to be pushed out of normal position.
At times, the lower canine teeth are positioned so that they place painful pressure on the roof of the mouth, leading to ulcers or even the formation of a hole into the nasal passages. In some cases, this can be corrected with an acrylic appliance placed on the upper teeth, which gently re-directs the offending teeth into normal alignment.

When base narrow lower canine teeth are seen in puppies, more than one treatment option exists. Extraction of the lower baby canine teeth will make the patient more comfortable, but this treatment rarely prevents the same condition from occurring in the permanent teeth. A newer treatment for these puppies involves placement of curved composite tip extensions (see case below) on the baby teeth to orthodontically tip them into a more normal position. When these baby teeth are then naturally lost around 5 months of age, the permanent canine teeth will usually erupt into a normal and comfortable position. For this technique to work, the tip extensions must be placed no later than 14 weeks of age. Placement around 12 weeks of age or earlier is preferred.
