1.Each person’s teeth are as unique as their fingerprints, often used for identifying human remains. Even identical twins have different teeth. Bonus fact: Your tongue also has a distinct “tongue print.”

2.Approximately one-third of each tooth is beneath your gums, emphasizing the importance of gum health. Healthy gums are pink and firm.

3.You have a total of 32 teeth, including eight incisors, four canines, eight premolars, and 12 molars.

4.Tooth enamel, the outermost layer, is the hardest substance in your body, primarily composed of calcium and phosphate.

5.Despite its toughness, enamel can still chip, crack, or decay due to sugars and acids interacting with bacteria in the mouth, leading to tooth decay.

6.Yellow teeth can indicate enamel decay rather than just surface stains, potentially causing pain.

7.Dentin, located beneath enamel, continues to grow and change throughout life, unlike enamel.

8.Your mouth harbors around 300 different species of bacteria, with Streptococcus mutans being a primary contributor to tooth decay.

9.Plaque, a white and sticky substance, continuously forms on teeth and can harden into tartar if not removed regularly by brushing and flossing.

10.Your body produces approximately one quart of saliva daily, totaling about 10,000 gallons over a lifetime. Saliva aids in swallowing, contains enzymes for digestion, and helps neutralize acids in plaque to prevent tooth damage.
