You use them every day to eat, speak, and smile, but how much do you actually know about your teeth? Though they may seem small, they carry very large responsibilities, and they also happen to be quite interesting in their own right! Here’s a closer look at some of the most unique and surprising facts about teeth that you probably never realized, along with why keeping them healthy matters much more than you think.

1. Enamel Is the Hardest Material in the Body

It might surprise you, but tooth enamel, or the outermost layer of your teeth, is even harder than bone! It’s the toughest, most mineralized tissue your body produces, designed to withstand a lifetime of biting, chewing, and grinding, but that doesn’t mean it’s indestructible. However, unlike your skin or bones, enamel has no living cells, which means it can’t repair itself once it’s damaged by decay, acid, or wear. Therefore, daily oral hygiene and routine dental care are the only surefire ways to protect it for life and ensure it’s able to continue shielding your smile.

2. No Two Smiles Are Exactly Alike

This isn’t just a cliché expression that you’ll find on a Hallmark card or on a motivational poster; it’s true on a literal level. Just like your fingerprints, your teeth are also one-of-a-kind! The size, shape, spacing, and alignment of them are entirely unique to you, which is actually why dental records are sometimes used to help identify individuals. This is also why every time you visit the dentist, your checkup and cleaning might look a little different from somebody else’s, as well as any future treatments that are planned; your needs vary, so things must be personalized. 

3. You Spend Around One Day Each Year Brushing Your Teeth

You probably already know that you need to brush your teeth twice a day, for two minutes each time. This adds up to four minutes every day, for a total of about half an hour each week. Believe it or not, this means that you’ll end up spending just over 24 hours each year brushing your teeth, assuming you keep up with the habit every day! While this might seem like a hefty time commitment, it’s absolutely worthwhile since it’ll protect your smile and prevent all kinds of painful issues.

Your teeth are remarkable, and most people don’t give them enough credit for what they do. Once you understand their role in dental health and overall happiness, it’s much easier to give them the attention they deserve!
