As far as dental hygiene is concerned, this a habit that you would ideally avoid. Unlike when you give a child a bottle during the day and they digest it before sleeping, if you put a child to bed with milk or juice—especially an older child who does not need it for sustenance but has just grown accustomed to it—the sugars in that drink will sit on their teeth all night and can cause cavities. If it makes you feel any better, we have to give adults who go to sleep with cough drops the same news. When you go to sleep, you want to avoid any sugars coating your teeth all night long.
One fun way to motivate children of all ages is to use technology. For small children, this can mean playing a fun song or video when they brush their teeth, like this one featuring Elmo. And there's always the traditional approach of using an “egg timer." Younger children, older children, and adults should all brush for two minutes. For older teens, Dentistry IQ has a list of cool tools they can use to brush and floss their teeth and braces. If your teen still seems uninterested in brushing their teeth, schedule an appointment for a dental cleaning. This way they can hear why brushing and flossing are so important from our dentists and hygienists .
