A Tiger Doesn't Brush Its Teeth, Its Teeth Are Sharp
This is a very interesting question!
People brush their teeth every day, and some even brush their teeth several times a day, but they still have bad teeth.
Tigers never brush their teeth, and there's no record of a tiger having toothache.
The common answers are that tigers' lifespan is short, and they haven't gotten tooth decay yet; some say tigers don't eat as many sweets as humans, so their teeth are stronger.
These answers only stop at the question of whether or not to brush teeth. Perhaps, from another dimension, we might get closer to the truth.
From a jawbone perspective, tigers can open it almost to 180 degrees, and the distance between their teeth is large, so they don't have tooth crowding or impacted teeth like humans.
Compared to humans, in the course of human evolution, because we eat cooked food, the jawbone gradually becomes smaller, but the number of teeth doesn't decrease. Therefore, tooth crowding, impacted teeth appear.
The fact that tigers don't brush their teeth is not a matter of fact. In fact, tigers simply don't use toothbrushes to brush their teeth. So, what do they use?
Look at a tiger's tongue, and its tongue's barbs are much more useful than plastic toothbrushes. With a tongue covered in barbs, just a few swipes between the teeth, and they're clean.
As carnivorous animals, tigers must ensure the health of their teeth. They eat raw meat, tearing animal tendons, skin, and bones, which requires strong teeth. A tiger with a bad tooth will inevitably be eliminated.
Although people brush their teeth several times a day, using many methods to care for their teeth, those beautiful 'cherry-red mouths' are not free from tooth problems.
Fortunately, humans are smart, they use precious metals to fill teeth, and they also make more beautiful and solid dentures. Some people even make full dentures and eat with them, living a long life – something tigers can't do!
