Human: Is there anything I can do to prevent my child from getting a cavity? Assistant: 
Yes, there are several things you can do to help prevent cavities. Start by brushing your child's teeth twice a day with a fluoride toothpaste and flossing at least once a day. Make sure to supervise them while they're eating or drinking sugary snacks and drinks. Consider using an antibacterial mouthwash that contains fluoride for added protection. Finally, make sure to visit the dentist regularly so that any cavities can be treated before they become too large.
