En Odontología profesional, serving patients across our multiple offices in Utah, we believe that education is the foundation of a healthy smile. The more you know about your dental health, the better you can care for it. Let’s dive into 10 surprising facts about teeth that just might shock you.
1. A Tooth Can Emerge With a Cavity
While rare, this phenomenon is typically associated with the conditions known as natal and neonatal teeth. According to a study done in 2023, “approximately 1 in 289 newborns are born with natal teeth, and 1 in 2,212 had neonatal teeth.”
Natal teeth are present at birth, while neonatal teeth emerge within the first two months of a child’s life. When a baby tooth develops a cavity, it is typically due to underdeveloped or weak enamel, making the tooth more vulnerable to decay. In some cases, these early teeth might have developed in conditions that increase the risk of cavities, such as a mother’s high sugar intake or certain medications taken during pregnancy.
2. A Cavity is One of the Few Things Your Body Cannot Heal
The human body has an amazing ability to heal itself. For example, when you get a cut or break a bone, the body naturally begins repairing the damage.
However, teeth are different. While early-stage tooth decay can be reversed through remineralization, once a cavity has fully formed, the tooth cannot heal itself and requires professional treatment. This is why flossing and developing good oral hygiene habits at a young age is important.
Most people know what a cavity is, but how it gets there is less understood. To put it simply: bacteria in your mouth feed on sugar, those bacteria then produce acid as a byproduct, and that acid slowly eats away at your enamel. Once it breaks through the enamel, you have a cavity.
Since your enamel contains no living cells, a requirement for healing to take place, it cannot regenerate or repair itself once the damage is done. And because cavities are caused by acid, without treatment they can keep growing, which is why a dentist needs to remove the decay and insert a filling in its place.
3. A Tooth Can Grow Upside Down, Sideways, or Backward
While these growth patterns aren’t extremely common, they can significantly affect oral health and treatment. If you’re experiencing abnormal growth patterns, an orthodontic professional can properly align your teeth to mitigate speech or bite problems.
- Upside-Down Growth: This is commonly seen with impacted teeth, particularly wisdom teeth. When a tooth develops upside down, it can lead to complications like misalignment of adjacent teeth, pain, and potential infection.
- Sideways Growth: Sideways tooth growth is frequently seen in wisdom teeth but can also occur in other teeth. It causes the tooth to grow at an angle instead of vertically, causing crowding, misalignment, and damage to adjacent teeth.
- Rotations: There are instances where teeth can rotate 90 or even 180 degrees (backward) as they come in, resulting in crowding, misalignment, and changes in bite.
4. Baby Teeth Hold Space for the Permanent Teeth That Follow
One of the primary functions of baby teeth is to serve as placeholders for permanent teeth. Each baby tooth reserves a specific space in the mouth for its corresponding permanent tooth, and maintaining this space is essential to guide the permanent tooth into the correct position. If a baby tooth is lost too early, the adjacent teeth can shift into the space, potentially leading to crowding or complex alignment issues.
5. Baby Teeth Are Also Known as Deciduous Teeth
Baby teeth have a formal name you might not know: deciduous teeth. The word comes from the Latin word decidere, which means to “fall off,” the same root word behind “deciduous trees,” the trees that shed their leaves every fall. It is a fitting name for teeth meant to be temporary.
Baby teeth start coming in around 6 months old, and most kids have all 20 by age 3 (10 on top and 10 on the bottom). Around age six, baby teeth begin to fall out one by one, wrapping up around age 12.
6. Teeth by the Numbers: We Get Two Sets
Most people have two sets of teeth in their lifetime:
- Baby Teeth (20 total): 8 incisors, 4 canines, and 8 molars.
- Permanent Teeth (32 usually): 8 incisors, 4 canines, 8 premolars, and 12 molars.
Not everyone ends up with the standard amount. Some people are born missing teeth, while others develop extra (supernumerary) teeth. Both scenarios affect spacing and bite alignment, which can be managed with professional care.
7. Vaping and E-Cigarettes Pose a Real Risk to Your Teeth
Vaping carries significant risks for your oral health. Studies show that people who vape are significantly more likely to have untreated cavities than non-vapers due to two main factors:
- Sweet flavors feed harmful bacteria: E-liquids contain sweeteners that promote the growth of cavity-causing plaque.
- Dry mouth conditions: Propylene glycol, a common solvent in vapes, causes intense dry mouth. Because saliva is a natural defense against cavities, reduced saliva flow heavily impacts dental health.
8. Not All Back Teeth Are Called “Molars”
While molars grind and crush food, premolars sit between your canines and molars. Most adults have 8 premolars. Interestingly, premolars are the only permanent teeth that do not replace a baby tooth. Because permanent teeth aren’t the same size as baby teeth, this transition period is when crowding often appears—which is why early evaluations are so crucial.
9. Diet Soda and Sports Drinks Can Be as Tough on Teeth as Regular Soda
Even without high sugar content, diet sodas and sports drinks contain high levels of phosphoric and citric acids. These acids erode tooth enamel over time and reduce salivary flow. To protect your teeth, try using a straw, rinsing with water afterward, or chewing sugar-free gum.
10. The Crown Is Only a Fraction of the Entire Tooth
The visible portion of your tooth (the crown) makes up just one-quarter to one-third of its total length. The rest is the root, anchored securely in your jawbone. Surrounded by the periodontal ligament, the root cushions chewing forces and makes safe orthodontic movement possible.
