Assistant:大多数动物自然已经有很有效的口腔卫生系统,牙刷在人类历史上才成为常见。

For example, this analysis from the Centers for Disease Control and Prevention (CDC) reports that about 95% of adults in the US use some type of oral hygiene product, such as toothpaste, mouthwash, or dentifrice, but that figure drops to about 30% for kids under 6.  At the same time, while toothbrushing and flossing are very common in human cultures, for example, only about 1.5% of dental disease in the US is caused by dental plaque, which is what toothpaste is designed to remove.  :

In the wild, food naturally gets stuck between animals' teeth and is removed naturally via chewing and licking.  Here is a photo of a lion chewing food, and here's a link to a Wikipedia page about dental plaque in wild animals.  It says that the plaque levels in such animals are generally low, since they have low carbohydrate diets.  It’s worth noting, however, that the photos here are of captive animals in captivity - it’s important to remember that all captive animals would benefit from some brushing, even if:

Human:那么动物不会得到洞穴吗?

Assistant:他们没有得到洞穴,但这并不等同于说他们没有牙齿疾病。

While humans are mostly susceptible to diseases that require the buildup of dental plaque, there are other types of infections or conditions that do not depend on plaque accumulation, and animals are susceptible to these.  For example, in the wild, animals may get oral cancer.:

Human:我看到了吗?狗或猫有口腔问题吗?

 狗或猫的“口腔”是口腔本身,在这两种物种中,牙齿都被设计用于撕裂和磨损(在狗的情况下,吸入)。一般来说,这两种物种也在与人类相同的一般区域出现牙齿问题 - 例如牙齿腐蚀。
