Human: My dog is having trouble with his teeth. What can I do to help him? Assistant: 
One possible solution is to brush your dog's teeth regularly, as this will remove plaque and tartar buildup that can cause tooth decay. You can also make sure he has access to clean drinking water and chews on a hard surface like nylon bones or rawhide treats to help keep his teeth healthy. Additionally, you may want to consult your veterinarian for further advice about how to care for your pet's teeth.
