When it comes to your child’s smile, every milestone matters. From that very first tooth to the arrival of a permanent grin, understanding the transition is key to long-term health. If you are looking for expert pediatric dentistry in Atlanta, GA, you likely have questions about how these two sets of teeth differ and why the change happens in the first place.
While they may look similar at a glance, baby teeth and adult teeth serve very different roles in a person’s life. Let’s dive into the fascinating world of dental development.
The Basics of Tooth Development
Humans are diphyodont, which is a fancy way of saying we grow two successive sets of teeth. The first set, known as the primary or deciduous teeth, begins to appear around six months of age. By age three, most children have a complete set of 20 baby teeth.
Eventually, these little teeth make way for permanent ones. A typical adult has 32 teeth, including wisdom teeth. This transition usually begins around age six and continues into the early teenage years.
How Do Baby Teeth Differ From Adult Teeth
If you compare a baby tooth to an adult tooth side-by-side, the differences become clear. It isn’t just about the size.
- Color: Baby teeth are usually whiter than adult teeth. Permanent teeth have more dentin, which gives them a slightly yellowish tint.
- Shape: Primary teeth are more rounded and have shorter roots. Adult teeth are more jagged when they first emerge (called mamelons) and have much longer, stronger roots.
- Structure: The enamel on baby teeth is much thinner than on permanent teeth.
Comparison Chart: Primary vs. Permanent
| Feature | Baby Teeth (Primary) | Adult Teeth (Permanent) |
| Total Number | 20 | 32 |
| Enamel Thickness | Thin | Thick |
| Color | Bright White | Off-white/Yellowish |
| Purpose | Placeholder/Speech | Lifelong Function |
Why Adult Teeth Are Stronger Than Baby Teeth
There is a biological reason for the difference in durability. Because primary teeth are only meant to last for a decade or so, they don’t need the heavy-duty armor that permanent teeth require.
Adult teeth have a much thicker layer of enamel and dentin. This makes them more resistant to wear and tear from decades of chewing. However, because baby teeth have thinner enamel, they are more prone to cavities. This is why visiting a dentist in Atlanta for regular checkups is vital, even for teeth that are destined to fall out.
The Role of Baby Teeth
You might wonder why we have baby teeth at all if they are going to disappear. These early teeth act as “space maintainers.” They hold the correct positions in the jaw so that permanent teeth have a guided path to follow.
If a baby tooth is lost too early due to decay, the surrounding teeth might shift. This can lead to crowding or crookedness when the adult teeth try to come in. Keeping these “starter” teeth healthy ensures a straighter smile later in life.
Caring for the Transition
When you look for a dental office near you, the focus is often on preventive care. As the “big” teeth start to arrive, the hygiene routine needs to level up. Since adult teeth are permanent, they require diligent brushing and flossing to last a lifetime.
The debate over baby teeth vs. adult teeth highlights that, while one is temporary, both are essential for speech, nutrition, and confidence.

Frequently Asked Questions
Why do baby teeth fall out?
Baby teeth are shed because the stronger teeth underneath them begin to move upward. As the baby tooth’s flesh dissolves, the tooth becomes loose and falls out.
At what age should my child see a dentist?
Most experts recommend a first visit by the first birthday or when the first tooth erupts. Routine visits help track the transition from primary to permanent sets.
Can adult teeth grow behind baby teeth?
When the permanent tooth comes into the mouth before the baby tooth falls out, it is called “shark teeth” in reference to the sharks that have many teeth. Usually, the baby tooth loosens on its own, but a dentist is monitoring it.
Do adult teeth need more care than baby teeth?
Both sets need care, but adult teeth need to be maintained forever. Their larger surface area and numerous grooves allow them to retain more plaque if not adequately cleaned.
