Teeth are fascinating! Did you know that tooth enamel is the hardest substance in the human body? Despite this, it's still vulnerable to decay without proper care. Humans have two sets of teeth in their lifetime – 20 primary (baby) teeth and 32 permanent teeth. Interestingly, no two people have the same teeth, much like fingerprints. The average person spends about 38.5 days brushing their teeth over a lifetime. Sharks continually lose and replace teeth, growing up to 30,000 in their lifetime! Elephants' molars can weigh up to six pounds each. Teeth start forming before birth, but they only emerge around six months. Keeping them healthy is crucial, so don't forget to brush, floss, and visit the dentist regularly!
