Impacted wisdom teeth are wisdom teeth that do not have enough room to grow properly. As a result, they can get stuck under the gums or inside the jawbone. Wisdom teeth are the last teeth to come in, usually between the ages of 17 and 25. Some people have no problems with their wisdom teeth. However, impacted wisdom teeth can grow at the wrong angle or only come through part of the gum.
This may cause pain, swelling, infection, tooth decay, gum disease, and damage to nearby teeth. If you are experiencing wisdom tooth pain in Goodyear, AZ or Queen Creek, AZ, our team is here to help.
What Are Impacted Wisdom Teeth?
Wisdom teeth are the third set of molars that grow at the very back of your mouth. Most people get four of them, one in each corner of the jaw. They are called wisdom teeth because they usually appear later in life when a person is considered older and wiser. An impacted wisdom tooth is one that does not have enough room to grow in properly.
Instead of pushing straight through the gum like a normal tooth, it gets stuck. It may grow at a wrong angle, push against the tooth next to it, or stay buried under the gum entirely. When a tooth is impacted, it can cause pain, infection, and damage to the surrounding teeth and bone.
Types of Impacted Wisdom Teeth
Not all impacted wisdom teeth are the same. They are classified based on how deep the tooth is and what angle it is growing at.
Soft Tissue Impaction
In this type, the tooth has pushed through the jawbone but is still partly covered by the gum tissue. The gum flap sitting over the tooth can trap food and bacteria, which leads to pain and infection.
Partial Bony Impaction
Here, part of the tooth has come through the bone, but it is still partially stuck inside the jaw. This type is harder to clean and is more likely to cause infection or damage to nearby teeth.
Complete Bony Impaction
In this case, the tooth is fully trapped inside the jawbone. It has not broken through the gum at all. This type often requires more complex surgery to remove.
Wisdom Tooth Impaction Classifications
Mesial impaction means the tooth is angled forward, toward the front of the mouth. This is the most common type and puts pressure on the molar in front of it. Distal impaction means the tooth is angled backward, toward the back of the jaw.
Vertical impaction means the tooth is growing in the right direction but does not have enough room to fully emerge. Horizontal impaction means the tooth is lying completely on its side.
What Causes Impacted Wisdom Teeth?
Impacted wisdom teeth happen when there is not enough space in the jaw for them to grow properly. Since they are the last teeth to come in, the other teeth are already in place, which can block their path. This makes the wisdom tooth stay trapped in the gum or jawbone.
They can also be caused by the tooth growing in the wrong direction or at a bad angle. In some cases, genetics (family traits) can affect jaw size and tooth position, making impaction more likely.
Symptoms of Impacted Wisdom Teeth
Some impacted wisdom teeth cause no symptoms at all. But when they do, the signs can range from mildly annoying to very painful.
Jaw Pain and Tenderness
Pain in the back of the jaw is the most common sign of an impacted wisdom tooth. It can be a dull, constant ache or a sharp pain that comes and goes. The pain may get worse when you chew or open your mouth wide.
Swollen or Bleeding Gums
The gum tissue around an impacted tooth often becomes red, swollen, and tender. You may notice bleeding when you brush or floss near the back of your mouth. This is usually a sign of inflammation or infection.
Difficulty Opening the Mouth
When the surrounding tissue becomes infected or swollen, it can make it hard to open your mouth fully. This condition is called trismus, and it can make eating and talking uncomfortable.
Bad Breath or Unpleasant Taste
If a wisdom tooth is partially through the gum, a small pocket forms between the tooth and the gum. Food and bacteria collect in this pocket and are very hard to clean. This leads to bad breath and a bad taste in your mouth that does not go away even after brushing.
Headaches and Ear Pain
The pressure from an impacted wisdom tooth can radiate outward. Many people experience headaches, earaches, or pain along the jaw line that they do not immediately connect to their wisdom teeth. If you have ongoing head or ear pain with no other cause, your wisdom teeth may be the reason.
Crowding of Nearby Teeth
As an impacted wisdom tooth pushes against the molar next to it, it can shift that tooth out of position. Over time, this pressure can cause crowding in the back teeth and even affect teeth further forward in the mouth.
Can Impacted Wisdom Teeth Cause Problems?
Impacted wisdom teeth can cause problems when they do not have enough space to grow properly. They may grow at an angle or stay trapped under the gums, leading to pain, swelling, jaw stiffness, and pressure on nearby teeth. This pressure can cause crowding, misalignment, or damage to surrounding teeth.
They can also increase the risk of infection and other dental problems. Because impacted wisdom teeth are difficult to clean, bacteria can build up around them, causing gum infections, tooth decay, or cysts. Early evaluation and treatment can help prevent these complications and protect your oral health.
How Dentists Diagnose Impacted Wisdom Teeth
Dentists diagnose impacted wisdom teeth by first examining your mouth and checking for signs such as swollen gums, pain, redness, or difficulty opening your mouth. They will ask about your symptoms and look for any problems affecting nearby teeth.
To confirm the diagnosis, dentists usually take dental X-rays. These images show the position of the wisdom teeth, whether they are trapped in the jawbone or gums, and if they are affecting surrounding teeth. In some cases, a 3D scan may be recommended to get a more detailed view before treatment or surgery.
Treatment Options for Impacted Wisdom Teeth
Treatment for impacted wisdom teeth depends on how severe the problem is and whether the tooth is causing pain or other dental issues.
Regular Monitoring If the impacted wisdom tooth is not causing pain or other problems, your dentist may recommend regular checkups and X-rays to monitor it.
Pain Relief Medications Over-the-counter pain relievers may help reduce pain and discomfort caused by an impacted wisdom tooth.
Treatment for Infection If an infection develops, your dentist may prescribe antibiotics to help control it before further treatment.
Professional Cleaning In some cases, cleaning around a partially erupted wisdom tooth can help reduce irritation and lower the risk of infection.
Wisdom Tooth Removal Surgical extraction is the most common treatment when an impacted wisdom tooth causes pain, infection, tooth damage, or other complications.
Coronectomy In certain situations, only the crown of the tooth is removed while the roots are left in place to reduce the risk of nerve injury. This option is less common and depends on the tooth’s position.
When Do Impacted Wisdom Teeth Need Removal?
Impacted wisdom teeth do not always need to be removed. However, dentists often recommend removal when the tooth causes pain, swelling, infection, tooth decay, gum disease, or damage to nearby teeth. Removal may also be advised if the tooth is trapped in a way that could lead to future dental problems.
Even if an impacted wisdom tooth is not causing symptoms, a dentist may suggest removing it if X-rays show a high risk of complications. Regular dental checkups help determine whether monitoring or extraction is the best option for your oral health.
What Happens During Wisdom Tooth Removal?
During wisdom tooth removal, a dentist or oral surgeon removes the tooth to help prevent pain, infection, and other dental problems.
Preparing for Surgery
Before surgery, your dentist or oral surgeon will review your X-rays, discuss anesthesia options, and give you instructions. You will likely be told not to eat or drink for several hours before the procedure if you are having sedation. You will also need someone to drive you home.
The Extraction Procedure
The surgeon makes a small cut in the gum to access the tooth. If the tooth is inside the bone, a small amount of bone is removed to free it. The tooth may be cut into sections to make it easier to take out. Once the tooth is removed, the area is cleaned and stitched closed. The whole procedure usually takes 30 to 60 minutes depending on how many teeth are being removed.
Anesthesia and Sedation Options
You have several options for managing pain and anxiety during the procedure. Local anesthesia numbs the area so you feel no pain but stay awake. Nitrous oxide (laughing gas) helps you relax. IV sedation puts you in a deeply relaxed or semi-conscious state. General anesthesia is used in more complex cases or for patients with severe anxiety.
Recovery After Impacted Wisdom Tooth Removal
Recovery after impacted wisdom tooth removal usually takes a few days to a week, although complete healing of the gums may take several weeks. Mild pain, swelling, and slight bleeding are common during the first few days and can usually be managed with prescribed medications and proper care. To support healing, follow your dentist’s instructions, rest as needed, eat soft foods, and avoid smoking, drinking through a straw, or vigorous rinsing.
Can Impacted Wisdom Teeth Be Prevented?
There is no guaranteed way to prevent wisdom teeth from becoming impacted. The size of your jaw and the way your wisdom teeth develop are mostly determined by genetics, and there is nothing you can do to change that.
However, there are things you can do to stay ahead of problems. Routine dental checkups starting in the early teenage years allow your dentist to watch how your wisdom teeth are developing. Early monitoring also means that if removal is needed, it can be done at a younger age when recovery is faster and the risks are lower.
When Should You See a Dentist?
You do not always need to wait until you are in pain to see a dentist about wisdom teeth. Regular checkups allow your dentist to catch problems early through X-rays. See a dentist right away if you have severe pain, swelling, trouble opening your mouth, or signs of infection such as fever or bad breath.
Even milder symptoms deserve attention. Ongoing gum soreness, mild jaw aching, repeated headaches, or small pimple-like bumps on your gum near the back teeth are all signs that something may be going on with your wisdom teeth.
Conclusion
Impacted wisdom teeth are very common but should never be ignored, even when they are not causing pain. Early checkups and regular X-rays help catch problems before they turn serious. If you are feeling pain, swelling, or pressure at the back of your jaw, see a dentist as soon as possible. Wisdom tooth removal is a routine procedure that millions of people go through every year.
Recovery is manageable and the relief is worth it. Understanding what impacted wisdom teeth and recognizing the symptoms early can help prevent serious dental problems.Take care of your teeth, stay on top of your dental visits, and never ignore pain that keeps coming back.

Frequently Asked Questions
Are impacted wisdom teeth always painful?
Some impacted wisdom teeth cause no pain at all, especially if they are fully enclosed in bone and not pressing on anything. However, painless does not mean harmless. They can still cause slow damage to nearby teeth and bone without any symptoms, which is why regular dental monitoring is important.
Can impacted wisdom teeth cause headaches?
Yes, they can. The pressure from an impacted wisdom tooth can radiate into the jaw, ear, and head, causing tension headaches and earaches. If you have frequent headaches with no clear cause, it is worth asking your dentist to check your wisdom teeth.
Do all impacted wisdom teeth need to be removed?
If an impacted wisdom tooth is fully enclosed in bone, not causing pain, and not threatening nearby teeth, a dentist may recommend monitoring it rather than removing it. Removal is only recommended when there is a clear problem or a high risk of future complications.
How long does wisdom tooth removal take?
The actual procedure usually takes between 30 and 60 minutes for all four teeth. Simple cases may take less time, while complex impactions can take longer. Your surgeon will give you a better estimate after reviewing your X-rays.
How long is recovery after wisdom tooth extraction?
Most people feel back to normal within 7 to 10 days. The first three days are usually the most uncomfortable, with swelling and soreness peaking around day two or three. Full tissue healing takes about two weeks, and complete bone healing can take a few months.
What happens if impacted wisdom teeth are left untreated?
Leaving a problematic impacted wisdom tooth untreated can lead to serious issues over time. These include infection that keeps coming back, damage to neighboring teeth, bone loss around the jaw, cyst formation, and shifting of other teeth. In rare cases, an untreated infection can spread and become dangerous.
