When it comes to brushing your teeth, the timing matters more than you might think. Many people brush their teeth after eating, thinking it’s the best way to keep their mouth clean.

However, brushing before eating is actually healthier for your teeth.

Here’s why:

During the night, bacteria build up in your mouth, forming a sticky layer called plaque. If you brush before eating, you remove this plaque, stopping bacteria from mixing with your food and creating harmful acids that can weaken your teeth.

Now, you might be wondering, “What if I still want to brush after eating?” It’s okay, but here’s the catch: brushing right after a meal, especially if you’ve eaten something acidic like fruit or juice, can actually harm your teeth.

The acid softens your enamel—the outer layer of your teeth—making it easier to wear down. Dentists suggest waiting about 30 minutes after eating before brushing to give your enamel time to harden again.

While many people brush after eating, brushing before is often better for protecting your teeth. If you choose to brush after, just be sure to wait a little while. This way, you can keep your teeth strong and healthy.
