What would happen if you didn’t brush your teeth for a year?

Everyone's health is different. So, someone could go without brushing for a year and get gum disease and no cavities. Others might have it the other way around. Some could come down with serious health problems. In rare cases, people with healthy diets and good genes could go without cavities, gum disease and health problems, Messina said.
But, even for those who would escape major problems, their teeth would be covered in plaque.
"It's not a lovely feeling," Messina



said.
Food particles would stick around. Meaning, the taste of salmon from Saturday dinner would mingle with Sunday brunch.
Morning breath would be a constant, and smell worse every day without brushing.
"It’s not going to be good for relationships with other people," Messina said. "You aren’t going to have a lot of friends."
The ADA recommends brushing teeth twice daily and flossing once daily. Toothbrushes should be changed when frayed, about every four months.
