Why don't cats have caries? - briefly
Cats do not develop cavities primarily because their diet consists mostly of meat, which does not adhere to teeth as carbohydrates do. Additionally, cats produce saliva that has a higher pH level compared to humans, which helps in reducing the risk of tooth decay.
Why don't cats have caries? - in detail
Cats, unlike humans, do not typically suffer from tooth decay or cavities. This intriguing phenomenon can be attributed to several factors that contribute to their dental health.
Firstly, a cat's diet is primarily composed of meat and bones, which are rich in calcium and phosphorus. These minerals are essential for maintaining strong teeth and bones. The act of chewing on bones also serves as a natural toothbrush, helping to remove plaque and tartar from their teeth.
Secondly, cats have unique salivary enzymes that play a significant role in preventing tooth decay. Their saliva contains an enzyme called lysozyme, which has antimicrobial properties. This enzyme helps to break down bacteria in the mouth, reducing the risk of plaque formation and subsequent tooth decay.
Thirdly, cats have a unique jaw structure that allows them to chew their food thoroughly before swallowing. This thorough chewing process ensures that food particles do not get stuck between their teeth, further minimizing the risk of tooth decay.
Lastly, cats are meticulous groomers and spend a considerable amount of time cleaning themselves. During this grooming process, they often use their tongues to clean their teeth and gums, which helps to remove any remaining food particles and bacteria.
In summary, the combination of a meat-based diet, unique salivary enzymes, efficient jaw structure, and thorough self-grooming habits contribute to cats' remarkable resistance to tooth decay and cavities.
