Having only 28 teeth as an adult is perfectly normal for many people. The typical adult dentition consists of 32 teeth, but this often doesn't reflect reality. The difference usually comes down to the absence of wisdom teeth (also known as third molars).
The Role of Wisdom Teeth
Most adults have their wisdom teeth removed in their late teens or early twenties. These teeth, the third molars, develop later in life, often erupting (coming through the gums) between the ages of 17 and 25. However, they frequently become impacted (unable to erupt properly), requiring removal to prevent complications such as pain, infection, and damage to adjacent teeth. This is a very common procedure.

Other Possibilities (Less Common)
While wisdom teeth removal is the most common reason, it's important to note that some individuals may naturally lack some or all of their wisdom teeth, or even other teeth. This condition, known as hypodontia, may require further investigation by a dentist or orthodontist. A dental X-ray can confirm the presence or absence of unerupted teeth.
In short: It's entirely possible to have only 28 teeth and be perfectly healthy. It's likely due to the absence of your wisdom teeth, either removed or never present.
