Zoo Dentistry: Ensuring the Oral Health of Captive Wildlife

Keywords Zoo, Dentistry, Animal, Vet

Abstract

Zoo dentistry is a specialized field within veterinary medicine that focuses on the dental care and oral health of animals in captivity, particularly those housed in zoos and aquariums. Just like humans, animals can suffer from dental issues that can affect their overall health and well-being. In the controlled environment of a zoo, it is essential to provide comprehensive dental care to ensure the health and longevity of the animals under the care of zookeepers and veterinarians. The article covers the importance of zoo dentistry, the challenges, various approaches and its future scope, along with some fun animal tooth facts.

The Importance of Zoo Dentistry

1. Health and Welfare: Dental problems can have severe consequences for animals in captivity, including pain, infection, difficulty eating, and even systemic health issues. Addressing dental issues promptly is essential for maintaining the overall health and welfare of zoo animals.
2. Nutrition and Feeding: Proper dental health is crucial for animals to eat their natural diets effectively. Dental problems can make it difficult for animals to chew their food properly, leading to malnutrition and other health issues. By addressing dental issues, zoo dentists ensure that animals can consume the appropriate diet for their species, promoting overall health and vitality.
3. Behavior and Enrichment: Dental problems can also impact an animal’s behavior and ability to engage in natural behaviors. Painful dental issues can lead to changes in behavior, such as decreased activity levels or aggression. Providing proper dental care can help alleviate pain and discomfort, allowing animals to exhibit natural behaviors and participate in enrichment activities.

Challenges in Zoo Dentistry

1. Species Diversity: Zoos house a wide variety of species, each with unique dental anatomy and requirements. Zoo dentists must have a thorough understanding of the dental anatomy of various animals to provide effective care.
2. Anesthesia Risks: Performing dental procedures on wild animals often requires anesthesia, which can pose risks, especially for species with unique physiological characteristics or health concerns. Zoo dentists must carefully assess the risks and benefits of anesthesia for each animal and take appropriate precautions to ensure their safety.
3. Limited Diagnostic Options: Unlike domestic animals, zoo animals may not readily cooperate with dental examinations or diagnostic procedures. Additionally, the availability of specialized diagnostic equipment may be limited in zoo settings, making it challenging to diagnose and treat dental issues effectively.

Approaches to Zoo Dentistry

1. Preventive Care: Preventive dental care, including regular examinations, cleanings, and dental hygiene practices, plays a crucial role in maintaining the oral health of zoo animals. Zookeepers and veterinarians work together to implement preventive dental care protocols tailored to the specific needs of each species.
2. Diagnostic Imaging: Diagnostic imaging techniques, such as dental radiography and CT scans, allow zoo dentists to assess the internal structures of an animal’s teeth and jaws non-invasively. These tools aid in the diagnosis of dental issues and help guide treatment decisions.
3. Surgical Interventions: In cases where dental issues cannot be addressed through preventive care alone, surgical interventions may be necessary. Zoo dentists may perform procedures such as tooth extractions, root canal therapy, and periodontal surgery, under anesthesia, to treat dental problems and restore oral health.

Collaboration and Research

1. Interdisciplinary Collaboration: Zoo dentistry often requires collaboration between veterinarians, dentists, zoologists, and other experts to provide comprehensive care for zoo animals. By leveraging the expertise of multiple disciplines, zoo dentists can develop innovative approaches to address complex dental issues.
2. Research and Education: Continued research and education are essential for advancing the field of zoo dentistry. Research initiatives focus on understanding the dental health needs of different species, developing new treatment techniques, and improving anesthesia protocols. Educational programs aimed at zookeepers, veterinarians, and veterinary students help disseminate knowledge and promote best practices in zoo dentistry.

Fun Facts by a Zoo Dentist

Dr Cedric Tutt, a veterinary dentist in Capetown, says “There is no reason for a facility which houses wildlife not to care for the dentition of their animals. Facilities which do not have routine dentistry and oral care systems in place are neglecting important aspects of animal health and wellbeing.”

Non-Human Primates: Non-human primates, like monkeys, apes and lemurs, some of which were initially pets, have their canine teeth ‘clipped’ because they had bitten their owners. This practice does not render the animal harmless but infact causes severe pain and debilitation, culminating in draining sinuses on the animals face. Some teeth can be salvaged by root canal therapy, while other must be extracted. Sweet fruit and other food can cause dental decay, requiring dental fillings in some animals.

Tigers and African lions: Cats range in size from the marbled cat to tigers and African lions but generally their dentition looks the same – the major difference being the size of the teeth.

Elephants: The elephant has tusks that may break exposing the pulp causing severe pain. They have about 6 sets of molar teeth, that are about the size of a building brick, and erupt into and then out of the chewing plane.

Rhinos: Rhinos’ teeth are simulate to this of a horse and they can develop similar problems like spaces between cheek teeth that trap food.

Hippos: Hippos’ teeth may become overgrown and require trimming.

Wolves and African Wild Dogs: Wolves and African Wild Dogs have dentition similar to that of the domestic dog. They usually suffer from fractured canines, which may require root canal therapy.

Bat-eared foxes: Bat-eared foxes have up to 46 teeth, 4 more than the dogs.

Dolphins: These magnificent marine mammals have up to 25-28 teeth in each jaw which means they have a total of 100-112 teeth. All of the teeth have the same shape, although the first and last teeth in each row are somewhat smaller than the rest. Dolphins often play with toys to keep themselves amused but these toys may be abrasive leading to excessive wear of the teeth.

Pandas: Red Pandas and their Giant black and white namesakes that are indigenous to China eat mainly bamboo. These animals have been known to develop tooth decay especially when part of the zoo diet provided, adheres to the teeth surface where it ferments forming acid. If detected early, the decayed material can be removed and a dental filling placed to protect the rest of the tooth.

Conclusion

Zoo dentistry plays a vital role in ensuring the health and well-being of animals in captivity. By providing preventive care, diagnostic imaging, surgical interventions, and collaborating across disciplines, zoo dentists work to address the unique dental health needs of a diverse range of species. Through ongoing research and education, the field of zoo dentistry continues to evolve, improving the quality of dental care for zoo animals around the world.
