The reasons why chinchillas make the sound of grinding teeth:

1. Breeders can observe whether there are bite marks in chinchillas’ houses or toys. The chinchillas are likely to have teeth growing. If the chinchilla is grinding its teeth too quickly, the breeder needs to feed it with teething sticks or apple branches regularly, so that the chinchilla will reduce the use of other items to grind its teeth. You can also feed some grass and nut foods daily, which can also help your chinchilla grind its teeth.

2. When a chinchilla suffers from jaundice hepatitis, it will make a grinding sound when eating and swallowing. After the breeder finds out, he needs to send the chinchilla to the pet hospital for examination and treatment in time

3. If the breeding environment is unhygienic or the food is unclean, chinchillas are prone to have worms in their stomachs. The toxins secreted by the worms will cause chinchillas to grind their teeth at night. Breeders need to feed anthelmintics in time.

4. When a chinchilla is frightened, it will also make the sound of grinding its teeth. The breeder needs to first eliminate the factors that make the chinchilla feel afraid, and then pet the chinchilla more and give it more care.

5. Chinchillas will also make teeth grinding sounds when eating, such as grass, nuts, etc. This is just a sound made by normal eating, and the breeder does not need to pay too much attention to it.
