When do wisdom teeth come in?

Wisdom teeth — your third molars — are the last set of adult teeth to grow in, emerging between the ages of 17-25, though they can appear as early as 13 or as late as early 30s. Most people have four, one in each corner of the mouth behind the second molars. Timing varies based on genetics, jaw size, and individual development — which is why regular dental X-rays starting around age 16 are the most reliable way to monitor their progress and catch potential problems early. Because modern jaws lack space for them, wisdom teeth may cause crowding, pain or infection and may require removal.

When do wisdom teeth come in and what age do they erupt?

Wisdom teeth typically come in between ages 17-25, which is why this stage is often referred to as the wisdom teeth eruption age. Here's a general timeline your Aspen Dental provider will use to monitor development:

• Around age 16: First X-rays may show wisdom teeth beginning to form beneath the gumline

• Ages 17–19: Wisdom teeth begin to push through the gums

• Ages 20–25: Eruption continues; this is when most people first notice symptoms

• Late 20s–early 30s: Delayed eruption is possible and not uncommon

• Never: 5–37% of people are missing one or more wisdom teeth entirely ²

Even if your wisdom teeth aren't causing symptoms, your Aspen Dental provider will track their development with annual X-rays to determine whether intervention is needed.

The purpose of wisdom teeth

Wisdom teeth are evolutionary remnants. Our ancestors had larger jaws and needed these extra molars to grind tough, raw foods — roots, nuts, and uncooked meats. As human diets changed and cooking became widespread, the need for a third set of molars diminished. Today, most people's jaws are too small to accommodate wisdom teeth. This mismatch between jaw size and tooth count is why wisdom teeth frequently cause crowding, pain, and infection.

Signs your wisdom teeth are coming in

When wisdom teeth come in, the most common signs include pain or a dull ache at the back of the jaw, swollen or tender gums, small white spots appearing at the gumline and difficulty opening your mouth. Watch for these specific signs:

Irritated or swollen gums 

Redness, puffiness, or tenderness in the gums at the back of your mouth is often the first sign. The gum tissue stretches as the tooth pushes through.

White spots on the gums 

These are the tips of the wisdom teeth breaking through the gumline — a visible sign that eruption is underway.

Jaw ache or pressure 

A dull, persistent ache in the jaw — toward the back — is a hallmark symptom. It may feel like pressure rather than sharp pain.

Difficulty opening your mouth 

Swelling around emerging wisdom teeth can limit how wide you can open your jaw.

Gum flap (operculum) 

Sometimes a flap of gum tissue covers an emerging wisdom tooth, trapping food and bacteria, which can lead to a painful infection called pericoronitis. Experiencing any of these symptoms? Schedule an appointment at your nearest Aspen Dental — the Aspen Dental team can take an X-ray and let you know what is happening with your wisdom teeth.

Pain in other areas of the mouth

When wisdom teeth come in, it's important to know that pain doesn't always stay localized. As these teeth push through, discomfort can radiate to:

• Neighboring teeth — pressure from an emerging wisdom tooth can cause aching in adjacent molars

• The jaw and ear — referred pain along the jaw nerve can feel like an earache

• The head — some patients experience tension headaches linked to jaw pressure

• The throat — swelling near the back of the mouth can cause mild throat discomfort

This referred pain pattern is why wisdom tooth problems are mistaken for ear infections, sinus issues or TMJ disorders. If you're experiencing unexplained jaw or ear pain, wisdom teeth are worth ruling out. If you're experiencing unexplained jaw, ear or head pain, schedule an appointment at your nearest Aspen Dental — an X-ray can quickly confirm whether wisdom teeth are the cause.

How to care for your wisdom teeth

When wisdom teeth come in, proper care focuses on keeping the area clean to prevent infection, managing discomfort with over-the-counter pain relievers and cold compresses and maintaining regular dental check-ups so your Aspen Dental provider can monitor eruption progress.

Here's how to manage wisdom teeth as they come in:

Maintain thorough oral hygiene  

Brush twice daily, paying extra attention to the back of your mouth where wisdom teeth emerge. Use a soft-bristled toothbrush and angle it toward the gumline. Floss daily — even if it's difficult to reach, removing food debris from around partially erupted teeth reduces infection risk.

Use an antibacterial mouthwash  

Rinsing with an antibacterial mouthwash helps control bacteria in hard-to-reach areas around emerging wisdom teeth. Warm saltwater rinses (½ teaspoon of salt in 8 oz of warm water) can soothe inflamed gum tissue.

Manage pain and swelling 

Ibuprofen (such as Advil or Motrin) is more effective than acetaminophen for wisdom tooth pain because it reduces both pain and inflammation — take 400–600mg every 6–8 hours with food, as directed on the package.³

Keep dental appointments 

Regular check-ups allow your Aspen Dental provider to monitor wisdom tooth development with X-rays and intervene early if crowding, impaction or infection develops.

Will you need to remove your wisdom teeth?

Not everyone needs wisdom teeth removed when they come in.⁵ Your Aspen Dental provider will recommend extraction if your wisdom teeth are impacted (unable to erupt), causing crowding or damage to adjacent teeth or leading to recurrent infections. If they erupt fully and are healthy, monitoring may be all that's needed.

Common reasons for extraction include:

Impaction 

When a wisdom tooth can't fully break through the gum — because of angle, bone or lack of space — it becomes "impacted." Impacted wisdom teeth can cause pain, cyst formation and damage to neighboring teeth. ²

Crowding 

Wisdom teeth that do erupt but push against adjacent teeth can disrupt your bite and undo previous orthodontic work. If crowding is a concern, your Aspen Dental provider may recommend removal and discuss alignment options such as clear aligners.

Recurrent infections (pericoronitis) 

Partially erupted wisdom teeth create a pocket between the tooth and gum where bacteria accumulate. This leads to a painful infection called pericoronitis, which can occur if the tooth isn't removed.

Tooth decay 

The location of wisdom teeth makes them difficult to clean effectively. Decay in a wisdom tooth — or in the adjacent second molar — is a common reason for extraction.

Your Aspen Dental provider will take X-rays to assess the position and health of your wisdom teeth and discuss whether extraction is the right course of action for you.

Wisdom teeth are the most commonly extracted teeth in the United States — approximately 5 million people have them removed each year, according to research published in the American Journal of Public Health.⁶

Extraction is easier and the recovery faster in late teens and early twenties, when the roots are not yet fully formed — which is why dentists recommend evaluation by age 18.³ Research published in the NIH's National Library of Medicine found that 72% of people aged 20–30 have at least one impacted wisdom tooth — making impaction the most common reason for extraction.⁴

How much does wisdom teeth removal cost?

The cost of wisdom teeth removal varies depending on the complexity of the extraction, whether the teeth are impacted and your insurance coverage. Simple extractions cost less than surgical removal of impacted teeth. At Aspen Dental, your care team will provide a transparent cost estimate before any treatment begins, and financing options are available.

Why are wisdom teeth removed?

Wisdom teeth are removed when they cause — or may cause — pain, infection, crowding, or damage to neighboring teeth. Removal is also recommended when wisdom teeth are impacted and cannot erupt properly. In some cases, an Aspen Dental provider may recommend proactive removal in young adults before problems develop, as recovery is typically faster at younger ages.

The American Dental Association recommends that patients have their wisdom teeth evaluated by age 18 to determine whether removal is advisable.³

Does insurance cover wisdom teeth removal?

Dental insurance coverage for wisdom teeth removal varies by plan. Many dental insurance plans cover a portion of the cost — when removal is deemed medically necessary due to impaction, infection or crowding. Simple extractions are more commonly covered than surgical procedures. Contact your insurance provider or ask your Aspen Dental care team to verify your benefits before your appointment.

Wisdom teeth FAQs

How do I know if my wisdom teeth are coming in?

The most common signs are a dull ache or pressure at the back of the jaw, swollen or tender gums, and small white spots appearing at the gumline where the tooth is breaking through. Some patients also notice jaw stiffness or difficulty opening their mouth fully. If you're unsure, an X-ray at Aspen Dental can confirm whether your wisdom teeth are erupting and how they're positioned.

Does everyone get wisdom teeth?

No — between 5% and 37% of people are missing one or more wisdom teeth entirely, and some people never develop any at all. Whether you have wisdom teeth is largely determined by genetics. Your Aspen Dental provider can confirm how many wisdom teeth you have and whether they are present beneath the gumline with a routine X-ray.

Can wisdom teeth cause ear pain or headaches?

Yes. As wisdom teeth push through, pressure along the jaw nerve can radiate to the ear, causing discomfort that feels like an earache. Some patients also experience tension headaches linked to jaw pressure from emerging or impacted wisdom teeth. This referred pain pattern is why wisdom tooth problems are frequently mistaken for ear infections, sinus issues, or TMJ disorders.

How long does wisdom teeth removal take?

A simple extraction typically takes 20–40 minutes per tooth. Surgical removal of impacted wisdom teeth takes longer — often 45–60 minutes for all four teeth when performed together under local anesthesia or sedation. Your Aspen Dental provider will give you a time estimate based on the position and complexity of your specific case.

Why do we have wisdom teeth if they cause so many problems?

Wisdom teeth are an evolutionary remnant. Our ancestors had larger jaws and needed a third set of molars to grind tough, raw foods. As human diets changed and cooking became widespread, jaw size gradually decreased — but the genetic blueprint for wisdom teeth remained. The result is a mismatch: teeth our ancestors needed that modern jaws often can't accommodate.

Does insurance cover wisdom teeth removal?

Many dental insurance plans cover a portion of wisdom teeth removal, when medically necessary. Coverage varies by plan — your Aspen Dental care team can help verify your benefits.

Is it necessary to remove wisdom teeth if they're not causing problems?

Not always. If wisdom teeth erupt fully aligned and can be cleaned, your dentist may recommend monitoring rather than removal. Regular X-rays will track any changes.

What if I choose not to have my wisdom teeth removed?

If you opt not to remove your wisdom teeth, maintaining excellent oral hygiene and attending regular dental check-ups is essential to monitor for developing problems such as decay, crowding, or infection.
