Adults aren't the only ones who need to worry about gingivitis and cavities. In developed countries like the United States, about 73 percent of children between six and 11 years old have gum disease, according to the National Institutes of Health (NIH). The NIH adds that 42 percent of two- to 11-year-olds have already experienced tooth cavities.
An oral hygiene routine that includes gentle mouthwash can help keep their teeth and gums healthy, but it's important that kids' mouthwash is used safely.
