Why Aren’t All of My Wisdom Teeth Grown In?

Not everybody develops wisdom teeth — also called third molars — or at least not all four of them. In fact, some researchers suggest that about 25% of the population is missing at least one wisdom tooth that never forms.
If you’re concerned about your wisdom teeth or if you’ve developed tooth or jaw pain, see Kenn Kakosian, DDS, PhD, and the general dentistry specialists at DentAlign NYC in Midtown East, Manhattan, New York, to schedule a dental evaluation.
Wisdom teeth 101
Your wisdom teeth are permanent molars that develop in the very back of your mouth, and they’re the last set of permanent adult teeth to erupt.
For a few people, four wisdom teeth grow in normally without any problems. Most never develop wisdom teeth or develop pain and other complications due to abnormal growth. The good news is that you don’t really need these third molars.
Reasons all four wisdom teeth haven’t grown in
Don’t have your wisdom teeth? The reasons these teeth might not all grow in include:
Missing wisdom teeth
Some people never develop all four wisdom teeth because of genetic reasons. Dr. Kakosian determines how many wisdom teeth haven’t yet erupted by reviewing your dental X-rays. Some people develop no wisdom teeth, while others have one, two, three, four, or even five in rare cases.
Impaction
If your wisdom teeth are impacted, they become stuck in your jawbone or gums and don’t erupt as intended. When this happens, wisdom teeth removal is often necessary to reduce your risk of cavities, infections, tooth crowding, adjacent tooth damage, gum disease, and pain.
Staggered eruption
Even if you have all four wisdom teeth, they may erupt at different times. If just one or two wisdom teeth have grown in, the others might not be far behind. Dr. Kakosian lets you know for sure based on your dental X-rays.
Signs of wisdom tooth impaction
It’s important to recognize the signs of wisdom tooth impaction to know when to see your dentist. Schedule an appointment if you experience:
- Jaw pain
- Tender, swollen, or red gums
- Bleeding gums
- Bad breath
- Unpleasant taste in your mouth
- Jaw or facial swelling
- Difficulty opening your mouth
About 90% of the population develops at least one impacted wisdom tooth.
Ways to avoid wisdom tooth complications
Dr. Kakosian keeps an eye on your oral health and tooth development when you attend routine dental exams, and he alerts you to potential wisdom tooth impaction or other complications by viewing your dental X-rays. His years of experience help him determine if you’re a candidate for extraction to avoid tooth damage or pain caused by problems with your third molars.
