Diseases of teeth in pets

It is important to note from the outset - in wild animalsteeth are healthier than at home. This is due to the fact that in nature, animals usually drink clean water and eat natural food that does not contain sugar. And cats and dogs living in apartments usually eat food bought in a store. Manufacturers of cheap food often add sugar to the composition, which negatively affects the teeth of not only humans, but also animals. The most common dental diseases in cats and dogs are:

  • tartar, that can cause pain when chewing food;
  • periodontitis, which leads to bleeding of the gums and also causes a lot of inconvenience;
  • stomatitis, manifested as painful ulcers on the mucous membrane of the mouth;
  • broken teeth occurring during fights and active games.

Therefore, the assumption that animals do not need to monitor their dental health is not entirely true. Watch out for the teeth of domestic cats and dogs very importantbecause of their diet, they are susceptible to oral diseases. But wild animals really do not have to worry about the health of their teeth and there are several reasons for this.

Domestic cats are more prone to dental disease

Animal saliva

Saliva is a colorless liquid thatexcreted in the oral cavity of humans and animals by the salivary glands. It is essential for softening food, making it easier to swallow, and protecting teeth from damage. Not only does saliva trite reduce the force of friction between the teeth, but it also has an antibacterial effect. The saliva of cats and dogs is acidic, which slows down the formation of plaque and caries. Since wild animals do not eat foods with sugar, these protective properties of saliva are sufficient to maintain healthy teeth.

Natural teeth cleaning

Herbivores brush their teeth right duringfood. For example, cows eat foods that are rich in fiber. To digest it, they have to chew food for a long time. When chewing, plant fibers thoroughly clean teeth from plaque and other phenomena that provoke dental diseases. Of course, the teeth of cows cannot be called perfect, but they clearly do not bring them any discomfort.

Cows brush their teeth without even knowing it

Short lifespan

Average human life expectancy in the world is 67 years old... Most people's teeth clearly can't standchewing food daily for such a long time. So you have to carefully monitor the health of your teeth, namely, brush them twice a day. And even with great efforts, many people fail to keep their teeth in perfect condition and have to resort to implantation.

Maintaining dental health into old age can be very difficult

And the life expectancy of animals is usually not that long. Cats usually live about 16 years old, and the lifespan of dogs is usually reaches 13 years old... During this time it is much easier to keep your teeth in good condition. Therefore, it is not surprising that adult dogs have healthier teeth than most people.

Restoration of teeth

But there are animals in the world that live longerof people. For example, in one of our materials, we found out that the lifespan of some fish exceeds 100 years. Many of them change their teeth to new ones several times during their lives. The so-called Carcharhiniformes renew about 35 thousand teeth during their life. And the mouth of alligators, which we wrote about in this article, manages to update about 40 times.
