Can animals get holes in their teeth?

The answer is - yes, they can. However, it is not as common, far from as common as for us humans.

Now you are of course wondering why this is so? The answer is not as complicated as you might think, believe it or not but the animals have no magic teeth.

The main reason is the diet. Sugar is, as most people know, the big culprit. And since carbohydrates are more or less sugar, it is precisely the carbohydrates that become the big culprit.
The animals' diet does not contain large amounts of carbohydrates as our diet does, hence they simply do not get cavities in the teeth to the same extent as us.
however, they can get cavities in their teeth, especially domestic animals that are fed with foods and feeds that are rich in carbohydrates.

In addition, many of them chew on hard things such as bones and bark, etc., which help keep the mouth clean, like toothbrushing.

Last but not least, the bacterial culture of the mouth plays a big role, but which is also related to the carbohydrates.
both we and the animals have bacteria in our mouths, both good and evil. And the bacterium that is the biggest cause of cavity caries is precisely Streptococcus mutans. But since they rarely consume carbohydrates, there is not much of this bacterium in their mouths.

However, they have some bacteria in their mouths that can cause gingivitis and periodontal disease.
