Why do we need to Brush our teeth when animals, who eat anything from raw meat to live vegetables don't get any of their teeth sore or rotten?
Do sharks get cavities?Phobos said:(1) Some animals replace teeth quickly (e.g., sharks with multiple rows of teeth or rodents with ever-growing teeth)
Actually, this is worth a second look. The things humans are dying of nowadays are things that they never would have dealt with when the average life expectancy was <30 years.Phobos said:(3) Many animals don't live long enough for tooth decay to be a concern.
http://www.polarbearsinternational.org/pbhc/sumvet.htmScheels offers his services to zoos and receives approximately 20 significant cases per year. He also trains other dentists and veterinarians in providing dental care to captive animals, and trains keepers on symptoms to look for that may indicate early dental problems.
Many of the cases on which Scheels consults are life threatening, because polar bears and other animals will hide discomfort. Because animals do not tend to show pain until the situation is critical, it’s important to look for early symptoms. Symptoms of dental problems can include loss of weight, drooling, slight behavior change, and body language (in the case of chronic pain). Open-mouth training is very valuable, and enables keepers to check for soft-tissue problems or discoloration.
Dental problems common in polar bears include:
Trauma (tooth fracture, fractured mandible)
Periodontal disease (most-common reason polar bears lose teeth)
Soft-tissue lesions or growths
Caries (decay)--typically from too much sugar in the diet
Diet is the best way to prevent many of these problems. Scheels also stressed the importance of having no chains or metal bars in enclosures--bears often chew on them and cause dental trauma.
The polar bear’s mandibular canine is the primary tooth to save. Scheels would not consider doing a root canal for a minor tooth. He might consider doing a crown on a young bear to prevent a tooth from splitting.
Couldn't resist Googling that one! The answer seems to be 'no' (especially since they loose & replace teeth so quickly), but here's a fun tidbit from a dentist's website for kids...Monique said:Do sharks get cavities?

There has never been a single cavity found in the ocean! In fact, on land we find only two groups of animals that experience tooth decay: human beings (and their domestic pets), and bears.
Have you figured out why so many people have needless cavities that require fillings? There are two reasons. First is our diet. Bears eat gallons of honey at a time. In over 22 countries, humans consume more than 120 pounds of sugar a year-per person! This causes a lot of decay. Dogs and cats in the wild never get a cavity, but when you feed them human food, they can get cavities. In some countries, like China, most people eat such small quantities of sugar that entire cities are cavity free. In fact, guess which country has the most cavities per person. That's right: the United State of America. So, if you never want another cavity, quit consuming sugar!
The second reason that fish don't get decay is that the ocean is one part per million fluoride solution. Fluoride is the l3th most common element on the planet. Fish and their teeth are constantly soaking in a fluoride solution!
Animals have a different diet and saliva composition than humans, which makes them less prone to tooth decay. They also have a faster rate of tooth turnover, meaning their teeth are constantly being replaced, which reduces the chances of cavities forming.
Yes, some animals can experience tooth decay. However, it is not as common as it is in humans. This is because animals have a more natural and varied diet, and their teeth are better adapted to handle the wear and tear of their diet.
Yes, animals' teeth are naturally resistant to decay due to their diet and saliva composition. Their teeth are also better equipped to handle the natural wear and tear of their diet, preventing the formation of cavities.
Yes, animals can get dental diseases such as periodontal disease and gingivitis. These diseases are caused by bacteria and can lead to tooth loss if left untreated. Regular dental care and proper nutrition can help prevent these diseases in animals.
Yes, some animals are more prone to tooth decay than others. For example, animals that are fed a high-sugar diet, such as domesticated pets, may be more susceptible to tooth decay. Additionally, animals that have a limited diet or have been injured or diseased may also be at a higher risk for tooth decay.
