Three Common Problems Caused by Wisdom Teeth

Wisdom teeth usually come in between ages 17 and 25, and for many people, they bring more problems than benefits. It’s common to wonder if it is normal to feel pressure in the back of my mouth, why does the pain keep coming and going, what happens if I just leave them alone?

For many people in Murrieta and beyond, there simply isn’t enough room for wisdom teeth to grow in comfortably. That’s why they often become impacted, push against other teeth, or create painful pressure in the jaw. Because they sit so far back, they’re also harder to keep clean, which makes them prone to infection and cavities. Left untreated, wisdom teeth can quietly cause bigger dental problems over time.

That’s why wisdom teeth removal is such a common procedure. Taking them out early can prevent bigger issues down the road. Understanding the signs that something isn’t right can help you make the best decision for your long-term oral health. Read on!

Do wisdom teeth actually cause problems?

Yes, they often do. While some people never develop noticeable issues, many experience impaction, infection, or nerve-related pain. The first signs of wisdom teeth coming in can include tender gums in the back of the mouth, swelling, soreness when chewing, and pressure behind the last molars. Even if the discomfort fades, recurring pain is usually a warning sign that the teeth aren’t erupting correctly.

Should you have your wisdom teeth removed?

It’s natural to wonder if wisdom teeth removal is really necessary. For some people, wisdom teeth erupt normally and never cause trouble. For many others, though, they eventually create problems.

• When removal is recommended: If you’re noticing recurring pain, swelling, or signs of infection in the back of your mouth, it’s usually a sign that your wisdom teeth are problematic. X-rays can also reveal if they’re crowding or pressing against other teeth. In some cases, patients report symptoms of wisdom tooth pressing on a nerve, such as tingling or radiating pain in the jaw, which is another signal that extraction may be necessary.
• Why early removal helps: Dentists often recommend taking wisdom teeth out in the late teens or early 20s. Younger patients usually heal faster, and removing them early can prevent bigger issues later on.
• When removal may not be needed: If your wisdom teeth are fully in place, painless, and easy to clean, your dentist may suggest monitoring them instead of removing them right away. Regular checkups and X-rays are important in these cases.

What kind of issues can wisdom teeth cause?

Here are the three most common dental problems linked to wisdom teeth:

1. Decay & cavities on the adjacent teeth

Because wisdom teeth are difficult to clean, food, plaque, and bacteria often get stuck between them and the neighboring molar. Over time, this leads to tooth decay on a tooth that may have been perfectly healthy before.

Why it matters: Untreated decay can spread quickly and require root canals, crowns, or even extraction of the damaged tooth. This problem is often preventable when wisdom teeth are removed before they cause harm.

2. Blocking other teeth from erupting normally

Sometimes wisdom teeth grow at the wrong angle and push directly into second molars, preventing them from erupting as they should.

Why it matters: This can create crooked teeth, an uneven bite, and difficulty keeping the area clean. The result is often a need for extensive orthodontic treatment, longer time in braces, or additional oral surgery. Early removal can prevent these complications.

In the first image, the upper second molars on both sides (red arrows) are being held back because the wisdom teeth above them are pushing them forward into the first molars. This pressure keeps the second molars trapped, so they can’t break through the gums as they should. You can see the difference when you look at the lower jaw—those second molars have erupted normally.

In the second image, the lower right wisdom tooth is blocking the second molar below it (blue arrow), stopping it from coming in. Because that molar is stuck, the upper second molar (red arrow) has started to “hypererupt,” meaning it’s dropping down lower than normal in an attempt to make contact. This misalignment throws off the bite and often leads to complex orthodontic issues that need significant treatment to fix.

3. Damage or resorption of neighboring teeth

Impacted wisdom teeth don’t just push against nearby teeth—they can cause resorption, which is when the pressure gradually wears away the tooth root next to it.

Why it matters: In severe cases, both the wisdom tooth and the adjacent molar are lost. Because resorption happens silently at first, dental X-rays are critical for catching the problem early.

Can wisdom teeth cause other body issues?

Yes. Infection from wisdom teeth can spread beyond the gums and affect the jaw, throat, and even sinuses. In rare cases, untreated infections can spread to other areas of the body, becoming a serious medical concern. Constant pain or swelling may also affect eating, sleeping, and overall quality of life. Some patients develop an early stage wisdom tooth infection without realizing it, where gum tenderness and mild swelling gradually worsen until treated.

What happens if you leave wisdom teeth in too long?

Leaving impacted or partially erupted wisdom teeth untreated can result in:

• Chronic gum infection (pericoronitis)
• Cavities on neighboring molars
• Jaw cysts or tumors in rare cases
• Long-term nerve damage if pressure continues
• Loss of both the wisdom tooth and adjacent teeth

In other words, avoiding treatment may turn a simple extraction into a much more complicated problem later on. Many people wonder why does wisdom tooth pain come and go, and the answer is that irritation or infection around the tooth can flare up when food gets trapped or when pressure builds, then ease temporarily before returning.

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

A healthy eruption usually feels like mild pressure without severe pain. The gums remain pink (not red or swollen), and you can clean the area without bleeding. On dental X-rays, the tooth appears upright with enough space behind the second molar. If pain, swelling, or crowding develops, it’s a sign that the tooth isn’t erupting properly. Paying attention to wisdom tooth pain symptoms, from throbbing aches to jaw tightness, can help you know when to see a dentist sooner rather than later.

What to expect during wisdom tooth extraction?

For many patients, fear of the unknown is the hardest part. The good news? Wisdom tooth surgery is one of the most common dental procedures, and your dental team will make sure you’re comfortable.

• Before the procedure: Your dentist or oral surgeon will explain anesthesia options, from simple numbing to sedation, so you won’t feel pain during the extraction.
• During surgery: The tooth is carefully loosened and removed. If it’s impacted, a small incision may be made to access it. The procedure usually takes less than an hour, even if all four wisdom teeth are removed.
• Afterwards: You’ll be given clear instructions for home care. Most patients go home the same day and rest comfortably.

How to prepare for wisdom tooth surgery

Taking a few steps before your procedure helps you feel confident and comfortable.

• Arrange a ride home, since sedation can make you groggy.
• Plan for a couple of quiet days with your favorite movies, soft foods, and ice packs ready.
• Follow your dentist’s pre-op instructions, such as not eating before sedation.
• Wear comfortable clothing and arrive a little early so you’re not rushed.

What to do if wisdom tooth pain becomes an emergency?

Sometimes wisdom teeth don’t give you much warning. If you experience severe swelling, fever, or intense pain, it’s time to call a dentist right away.

• Short-term relief: Saltwater rinses, over-the-counter pain relievers, and cold compresses may help until you can be seen.
• When to seek urgent care: If you have difficulty swallowing, opening your mouth, or notice spreading swelling, don’t delay — infections can spread beyond the mouth if untreated.
• The good news: Oral surgeons can usually provide immediate relief, whether through antibiotics, drainage, or emergency extraction. Acting quickly prevents bigger problems.
