In addition to taking your guinea pig to the vet, there are a few things you can do at home to help keep their teeth healthy. Provide them with plenty of hay to chew on, as this will help to wear down their teeth. You can also give them a variety of hard vegetables and fruits, such as carrots, apples, and broccoli. These foods will also help to keep their teeth healthy and strong.
It is important to monitor your guinea pig's teeth regularly so that you can catch any problems early on. If you notice that their teeth are starting to grow too long, be sure to take them to the vet as soon as possible.
