Should you brush your teeth before or after breakfast?
What experts say. There are pros and cons for both.
The question - Is it better to brush your teeth before or after breakfast or a cup of coffee?
The science - We all have our morning routines. Some of us make a beeline for the bathroom to brush away morning breath. Others prefer to start with a cup of coffee and a bit to eat before brushing. But which is better for your teeth? We asked dental experts to explain the science — and tell us their own personal preferences. There is a case to be made for brushing your teeth before eating or drinking. Microorganisms in the mouth, such as bacteria, can cause a bad taste and odor, and in dental plaque — a film made up of primarily bacteria, food particles and saliva — can lead to cavities, gingivitis and other forms of disease. Brushing your teeth with a fluoride-containing toothpaste and gum the correct technique when you wake up helps remove plaque and bacteria that develop overnight. This can make “juice, coffee and breakfast” taste better, and the toothpaste coats your teeth with fluoride and other minerals that protect your teeth during the meal.
