Food Stuck in Teeth
If you skip brushing before bed, food you eat throughout the day will sit on your teeth and weaken teeth all night long. Make sure you get all the food out of your child’s teeth by flossing and brushing before bed. If your child has a bottle or breastfeeds in the middle of the night, make sure you brush teeth again or at least wipe teeth before going back to sleep.
Reduced Saliva Flow at Night
Our brain is very smart and reduces saliva flow when you are sleeping, so you don’t drool. That means there is no continual cleansing action from saliva when you are sleeping. Saliva is rich in bone and tooth building materials such as calcium and phosphate. High saliva flow during the day means it continually rinses your teeth and strengthen them, too.
If you use fluoridated toothpaste or mouth rinse before you go to bed, it will sit on your teeth until you eat or drink the next day. Fluoride will strengthen teeth and fight cavities while you sleep.
