Dentistry is a very important component of veterinary care for the animals at the Detroit Zoo. Many of the animals here live longer than their wild counterparts, so ensuring that they have healthy teeth throughout their lifetime is a priority.

Dental issues can have a big impact on comfort and the overall well-being of an animal. We sometimes find that if an animal is showing a decrease in appetite or is experiencing weight loss or other problems, they ultimately have underlying dental problems. Whenever we do an exam on an animal, we are sure to carefully examine the teeth for problems and to scale and polish them to remove tartar or plaque. If we see problems or areas of concern, we take skull or dental radiographs to look for problems under the gum line, just like you experience during your routine dental visits.

Recently, one of our zookeepers noticed that a red panda was not opening his mouth fully when taking in food items such as grapes. We examined him under anesthesia three times over a short period, and despite anticipating a dental issue, we were unable to find any areas of concern during examination and radiographs. We collected diagnostic samples and treated him with antibiotics and anti-inflammatory and pain medications. Each time, the problem improved and then recurred. When the red panda started having problems most recently, we decided to transport him to a nearby veterinary specialty practice for a CT scan. This advanced imaging technique took only about 20 minutes, and was able to clearly delineate an area of infection underneath one of his upper molars. Usually dental issues can be pinpointed with regular radiographs, but in this case diagnosis proved extra challenging.

We made arrangements to transport the red panda to a board certified veterinary dentist, Dr. Ben Colmery at Dixboro Veterinary Dental and Medical Center in Ann Arbor. Dr. Colmery was able to remove the problem tooth, which allowed the infection to drain clear of the area. Within days, the red panda was opening his mouth wide to eat all of his food items and seemed much more comfortable.

Every member of the Zoo’s veterinary staff helped during one or more of the red panda’s examinations and treatment. This case demonstrates how teamwork, persistence, and assistance from outside experts can lead to a great outcome for our treasured animal patients. I’m thankful for the assistance that we receive from our veterinary colleagues, and proud of the great work that we do in the Ruth Roby Glancy Animal Health Complex!
