What are some ways to protect your teeth?

My teeth have always been very good. When fighting with my husband, if he is armed to the teeth, he will definitely die. My health regimen is as follows. Never use toothpaste. Toothpaste is a deceptive taste and has no cleaning effect. This is what a dentist said. I don’t brush my teeth when I get up in the morning. I brush my teeth three times a day after eating. Brush with clean water. Eat beans. Chewing is good for dental health, especially hard foods like broad beans and soybeans. Modern people's food is too refined and their teeth cannot be exercised. They must chew these things to exercise their teeth. Teeth tapping training. Keep tapping your upper teeth and lower teeth against each other dozens of times every day. Try not to eat sweets.
