Some people are born without certain teeth, and this condition is called congenitally missing teeth.

The most common missing teeth are wisdom teeth, upper lateral incisors, and second premolars/bicuspids.

Short answer, genetics. There is a term that’s used when a person is missing 6 or fewer permanent teeth, hypodontia. It’s a birth defect that is caused by abnormal changes in the genes. When a person is missing more than six permanent teeth, it’s called oligodontia.
Why are there no wisdom teeth in my mouth?
Like hypodontia, missing wisdom teeth is caused by a genetic anomaly. Thousands of years ago, a mutation developed that suppressed the formation of wisdom teeth. Fossils have been found in China dating back 300,000 to 400,000 years old that are missing third molars. So this mutation has been around for a while.
