4. Snacks linger
Enjoyed that sweet latte? That tasty muffin? Your snack probably only filled your tummy for a short while, but the impact on your teeth lasts for three hours. That’s how long the pH in your mouth is changed after you eat, and how long bacteria have a chance to build up plaque and work away at your enamel. Drinking a glass of water, brushing your teeth, chewing gum or swishing with mouthwash can clean out you mouth and prevent damage.
