Oral pathologist Wei Jian revealed the 5 most dangerous habits to the health of the teeth and gums, “nail biting, squeaking, and using wooden chopsticks.” He warned that these habits could lead to gum sensitivity, fracture, and crooked teeth.
He advised the need to stop biting nails with the teeth, as they might leave them broken and crooked, and he also warned against using wooden chopsticks, which could cause gum recession. Doctor Jian pointed out that: “The squeak on the teeth causes them to crack and fracture, and also weakens them completely.”
