Do All Adults Get Wisdom Teeth?

TLDR

Wisdom teeth don’t follow the same rules for everyone; some people develop all four, others develop none at all. Whether your third molars are missing due to genetics or are hidden beneath the gums (impacted), regular dental checkups with our dentists in Sumter, SC, are essential to prevent crowding, infection, and damage to your other teeth.

What You Should Know About Wisdom Teeth

Do all adults get wisdom teeth? It’s one of the most common questions we hear when patients visit us for wisdom teeth removal in Sumter, SC. While these third molars are often associated with adulthood, the truth is that every smile is unique: some people have four, some have none, and others fall somewhere in between.

To help clear up the confusion, Dr. Ray and Dr. Cain, our family dentists in Sumter, regularly explain the science behind wisdom teeth. Here we break down everything you need to know about the final stage of dental development, whether you’re currently experiencing dental discomfort or simply want to stay ahead of your oral health.

What are Wisdom Teeth?

Wisdom teeth, or third molars, are the final set of teeth to develop in the back of our mouth, typically erupting between the ages of 17 and 25. Historically, our ancestors needed these extra grinders to process a tough, raw diet of roots, nuts, and meat. However, as human diets softened and our brains grew larger, our jaw sizes began to shrink. Evolutionarily speaking, many of us no longer have the “real estate” in our mouths to accommodate these late arrivals.

Do All Adults Have Wisdom Teeth?

The short answer is no. While the majority of people develop all four wisdom teeth (one in each corner of the mouth), studies show that roughly 5% to 37% of people are missing at least one third molar. In fact, it is possible to have two, three, or even none at all!

Genetics plays the starring role here; if your parents never developed wisdom teeth, chances are that you won’t either. Research published in PLOS ONE suggests that genetic and environmental factors during early dental development can prevent the third molars from forming. The study also found that women are more likely than men to be missing one or more of their wisdom teeth.

Wisdom teeth may develop but remain impacted, meaning they stay trapped beneath your gum tissue or bone and never fully erupt into your mouth. In these cases, you may not realize you even have wisdom teeth unless our Sumter dentists discover them through dental X-rays.

Should You Have Your Wisdom Teeth Removed?

When wisdom teeth develop, they do not always erupt properly. Because they appear at the very back of the mouth, often where space is limited, they can lead to the following dental complications:

Crowding and Misalignment: When a large tooth tries to squeeze into a small space, it pushes the other teeth out of the way. This can ruin years of orthodontic work and cause straight teeth to become crooked.
Impaction and Infection: Many wisdom teeth grow in at an angle, sometimes even horizontally, which can cause significant pain and damage to neighboring teeth. Because these impacted teeth are difficult to reach with a toothbrush, they become breeding grounds for bacteria, leading to painful infections or cysts.

Choosing to remove them isn’t just about stopping current pain; it’s about proactive protection. Removing them early can prevent decay in neighboring molars, eliminate the risk of sudden, painful infections, simplify your hygiene routine, and ensure your bite stays healthy for the long haul.

Why our Sumter dentists recommend wisdom tooth extraction.

Persistent pain or pressure in the back of your mouth

What Should I Expect During Evaluation?
