We all know the traditional steps for dental care, such as brushing twice daily, using mouthwash, and regularly flossing to maintain oral hygiene. However, it’s easy to overlook the best practices for protecting tooth enamel.

• Neglecting Oral Health Can Be Life-Threatening

A dental hygiene expert on TikTok, known as “Madame Sweet,” shared her top tips for optimal dental health in a recent video where she explained the “30-Minute Rule.”

The 30-Minute Rule Explained

Madame Sweet advised, “Here’s the plan. Wait until you’ve finished dinner and then brush your teeth, but you should wait 30 minutes. This is because when you eat, there is a lot of acid in your mouth, which weakens the enamel. So, you should wait until it hardens again before brushing your teeth.”

The video received more than 19,000 views on TikTok.
