There are rumors that dogs’ mouths are not very clean.
, even though dogs will eat dead animals and other dirty food, their mouths are still cleaner than human mouths. Even if people brush or floss their teeth frequently and use tooth cleaning products, the result is still the same. It sounds like a dog’s mouth is almost a dental mystery, so is it really as rumored? This is obviously impossible.
Simply put, dogs' mouths may contain the same bacteria as humans, and they may also suffer from dental diseases similar to humans. Scientists think this is like comparing apples to oranges. Although there are many similar bacteria in both species, the question of which one has a cleaner mouth is irrelevant. Because both humans and dogs contain microorganisms in their mouths, and in most cases, the bacteria in dogs’ mouths are different from those in humans. The bacterium Porphyromonas is one example. This is a rod-shaped bacterium that causes periodontal disease, causing severe gum disease, loosening of teeth, and eventual tooth loss in humans and animals. Scientists found the bacterium in two different species: p.gingivalis was found in human dental plaque, while its symbiotic counterpart, p.gulae, was found in the mouths of dogs. These two kinds of bacteria will grow in the periodontal tissue and infiltrate the gums, eventually causing the rock-solid teeth to fall out.
Dog's mouth needs to be cleaned regularly
Although there is no clear relationship between dog breed and periodontal disease so far, puppies and older dogs are often at a higher risk of getting the disease. However, tooth decay, which is rare in humans, is a disease that is not easy for dogs to suffer from. According to a report issued by the World Health Organization in 2003, tooth decay affects 90% of children in the world, but only affects 5% of dogs. The reasons are complicated, but most scientists believe it is due to a lack of a secretion in the dog's mouth.bacteria. The culprit is Streptococcus mutans, which separates large sugar molecules into two smaller sugar molecules, producing acid in the process. Therefore, this bacteria has evolved to require a slightly acidic environment during its growth. So it ends up in a human's mouth, which is more acidic, rather than a dog's mouth, which is alkaline.
There is also a related rumor that being bitten by a human is more contagious than being bitten by a dog. However, this statement obviously does not stand up to scrutiny. According to a veterinarian, the dangers of human bites and dog bites depend on the type of bacteria in the mouth and the depth of the wound. Therefore, no matter what you are bitten by, you must remember to clean the wound thoroughly afterwards. If you feel that the wound involves muscles, then go to the hospital for treatment as soon as possible.
There are also some issues worthy of attention. Although the food currently eaten by pet dogs is often purchased dog food, and owners often also Clean your dog’s mouth regularly. However, you still should not get too close to the dog, and try to avoid behaviors such as kissing the dog. Also, don’t let dogs lick their mouths, let alone areas with wounds. This is a great threat to our own health. As for the statement that dog mouths are cleaner than human mouths, don’t take it seriously.
