How do you know when your wisdom teeth

Overview

Impacted wisdom teeth are third molars at the back of the mouth that don't have enough room to emerge or develop normally.

Wisdom teeth are the last adult teeth to come into the mouth (erupt). Most people have four wisdom teeth at the back of the mouth — two on the top, two on the bottom.

Impacted wisdom teeth can result in pain, damage to other teeth and other dental problems. In some cases, impacted wisdom teeth may cause no apparent or immediate problems. But because they're hard to clean, they may be more vulnerable to tooth decay and gum disease than other teeth are.

Impacted wisdom teeth that cause pain or other dental complications are usually removed. Some dentists and oral surgeons also recommend removing impacted wisdom teeth that don't cause symptoms to prevent future problems.

Symptoms

Impacted wisdom teeth don't always cause symptoms. However, when an impacted wisdom tooth becomes infected, damages other teeth or causes other dental problems, you may experience some of these signs or symptoms:

  • Red or swollen gums
  • Tender or bleeding gums
  • Jaw pain
  • Swelling around the jaw
  • Bad breath
  • An unpleasant taste in your mouth
  • Difficulty opening your mouth

When to see a doctor

See your dentist if you experience symptoms in the area behind your last molar that may be associated with an impacted wisdom tooth.

Causes

Wisdom teeth (third molars) become impacted because they don't have enough room to come in (erupt) or develop normally.

Wisdom teeth usually emerge sometime between the ages of 17 and 25. Some people have wisdom teeth that emerge without any problems and line up with the other teeth behind the second molars. In many cases, however, the mouth is too crowded for third molars to develop normally. These crowded third molars become trapped (impacted).

An impacted wisdom tooth may partially emerge so that some of the crown is visible (partially impacted), or it may never break through the gums (fully impacted). Whether partially or fully impacted, the tooth may:

  • Grow at an angle toward the next tooth (second molar)
  • Grow at an angle toward the back of the mouth
  • Grow at a right angle to the other teeth, as if the wisdom tooth is "lying down" within the jawbone
  • Grow straight up or down like other teeth but stay trapped within the jawbone

Complications

Impacted wisdom teeth can cause several problems in the mouth:

  • Damage to other teeth. If the wisdom tooth pushes against the second molar, it may damage the second molar or increase the risk of infection in that area. This pressure can also cause problems with crowding of the other teeth or require orthodontic treatment to straighten other teeth.
  • Cysts. The wisdom tooth develops in a sac within the jawbone. The sac can fill with fluid, forming a cyst that can damage the jawbone, teeth and nerves. Rarely, a tumor — usually noncancerous (benign) — develops. This complication may require removal of tissue and bone.
  • Decay. Partially impacted wisdom teeth appear to be at higher risk of tooth decay (caries) than other teeth. This probably occurs because wisdom teeth are harder to clean and because food and bacteria get easily trapped between the gum and a partially erupted tooth.
  • Gum disease. The difficulty cleaning impacted, partially erupted wisdom teeth increases the risk of developing a painful, inflammatory gum condition called pericoronitis (per-ih-kor-o-NI-tis) in that area.

Prevention

You can't keep an impaction from occurring, but keeping regular six-month dental appointments for cleaning and checkups enables your dentist to monitor the growth and emergence of your wisdom teeth. Regularly updated dental X-rays may indicate impacted wisdom teeth before any symptoms develop.

When you become an adult, you can expect wisdom teeth to grow in. These are molars at the very back of your mouth, but serve no purpose — they make an appearance between the ages of 17 and 21 (or later!) and mostly cause problems.

Don’t worry, though — wisdom teeth removal is a painless and common procedure.

Despite the fact that almost everyone has them and most people experience their removal, it’s still important to be aware of them.

The fact they’re common doesn’t mean they can’t cause complications, so it’s essential to be aware of how to tell if your wisdom teeth are coming in.

That way, if there are any complications, you can see a dentist to have them removed. 

1. Irritation Around the Gums

With mild periodontal disease being very common, most people have experienced irritation around the gums at least once in their life and aren’t alarmed by it. 

However, if it’s toward the back of your mouth and around the right time, it may not be caused by flossing that isn’t vigorous enough or inconsistent brushing. It could be caused by your wisdom teeth.

When they’re pushing their way through, one of the common signs of wisdom teeth growing in is red swelling in the gums. It’s an understandable sign — new teeth are breaking through, and that isn’t always going to be an easy, smooth process. 

Speak to your dentist if you ever experience irritation in the gums but if it’s at the back of your mouth, don’t be surprised if they let you know that the cause is those pesky wisdom teeth making an appearance.

Fortunately, having removal surgery will cure the irritation if this is the cause. 

2. Pain Around the Mouth, Jaw, or Head

People are often surprised that there’s a connection between wisdom teeth and headaches, but wisdom teeth don’t just cause pain in the mouth.

Although the first sore sign of wisdom teeth is likely going to be felt in the mouth, it can go further than that. It can spread down around the jaw and even cause headaches, particularly if more than one tooth is making its way in at the same time.

The reason for this is that wisdom teeth force teeth to move aside to make room for them. This can cause the pain and discomfort you’ll often experience in your jaw, as your whole mouth is shifting to make room.

Sometimes, it even becomes difficult to open and close your mouth.

In more rare cases (but still very possible!), they will push against your sinuses as they grow and this is what often causes headaches.

3. Bad Breath

Impacted wisdom teeth are what everyone dreads, but they’re common. Because there isn’t enough room for them to grow, they start to grow sideways and become impacted (or half-trapped) under the gum, coming to a grinding halt.

While this can be the cause of the pain, discomfort, and irritation you might be experiencing, it also comes with another unpleasant symptom. Bad breath.

A tooth growing awkwardly can cause pockets around the gums and teeth that are difficult to clean. Bacteria can become trapped there and without regular visits to the dentist, it will build up over time.

You may begin to notice that you have bad breath no matter how much you clean your teeth or even an unpleasant taste at the back of your mouth.

If it isn’t going away with some toothpaste and floss, it’s time to see a dentist in case a sideways wisdom tooth is causing the issue. 

4. Accidentally Biting Your Cheek or Tongue

Sometimes wisdom teeth move your other teeth aside so slowly that you don’t quite notice they’re there for a while. There might have been the occasional ache or redness that you brushed off, but ultimately, you haven’t really noticed that the rest of your teeth have moved to make room for new invaders.

Until you bite down on your tongue and the inside of your cheek. Repeatedly.

With your teeth moving ever-so-slightly to different spaces in your mouth, you may not be used to their new place and misjudge once-automatic bites into food.

If you’ve noticed this happening at a frequent rate, take a look for some other symptoms or speak to your dentist. 

5. Look — They Just Might Be Visible

An obvious sign that your wisdom teeth might be appearing is the appearance of them.

It may not be obvious. Stand in front of a mirror and take a flashlight to your mouth so you can have a good look at the back of your gums.

It may not be the teeth yourself you see — there might be a lump in there or some swelling you’ve never noticed. 

Or it might well be the teeth! Perhaps one of these new molars has burst through or began to, and you can see some white shining through the gum. Often, it doesn’t take a dentist to tell you that your wisdom teeth have decided it’s time to come through.

It’s Important You Know How to Tell if Your Wisdom Teeth Are Coming In

If you know how to tell if your wisdom teeth are coming in, their arrival is usually pretty obvious. Some discomfort is widely associated with wisdom teeth although if you’re lucky, the pain won’t be too bad and they won’t be impacted.

Even if this is the case, it might be wise to look into their removal. Wisdom teeth serve no purpose and getting rid of them early means they can’t cause you any of the problems that other, less fortunate people experience, such as sinus headaches and bad breath.

If you suspect your wisdom teeth are here, speak to your dentist about the best option.
