Contents

As we are all aware, humans are said to have 32 teeth. 28 teeth are likely to erupt by the age of 13-14 years and the rest of the 4 teeth are the third set of molars in your mouth which are called wisdom teeth. They are placed at the last in the mouth and are the last to emerge in the mouth. Commonly the wisdom teeth erupts during 17 to 25 years of age, however that is not the case always. It is normal to feel slight discomfort during the eruption of the teeth. It is a cause for concern when there is pain or swelling associated with it. Some of us may or may not have wisdom teeth.

Wisdon teeth

Very few people have wisdom teeth which erupt properly and cause no problems. Often, it can grow at an angle because of the lack of space or it can get stuck inside the tissues and that can cause a lot of issues. When the teeth is stuck inside the jaw bone it is called as impacted wisdom teeth. When only half of the teeth is out of the bone and the other half is below the gums , it is called as partially erupted wisdom teeth.

It is common to have missing wisdom teeth and it is not an issue. Wisdom teeth do not erupt for a variety of reasons, including a lack of space in the dental arch, thick bone above the wisdom tooth, or an accidental upside-down wisdom teeth. In most cases, impacted wisdom teeth do not cause any issues.

  • Tooth pain
  • Food getting stuck in between the teeth.
  • Gum pain, swelling or bleeding.
  • Jaw rigidity and limited mouth opening.
  • Pain near the ear while opening your mouth wide. 

If you have pain, visit your dentist. They may take an x-ray to see the position of the tooth in the jaw. The treatment is on case by case basis. The treatment can be a filling or root canal in some cases or doing nothing but wait and watch. Other treatments can be removal of the swollen gum tissue or symptomatic pain management. If the tooth is causing problems and it has no space for it to erupt into the jaw then it may have to be removed.

  • Food lodgement which occurs often
  • Pain in that tooth or surrounding the tooth 
  • Swelling or redness in the tooth region 
  • Difficulty/ Reduced mouth opening 
  • Before braces to create space

You cannot prevent having impacted wisdom tooth but proper oral hygiene practices can reduce the amount of problems caused by it. Visit your dentist regularly for overall better dental health.

Frequently Asked Questions

Wisdom teeth usually erupt between ages 17 and 25, which is why this period is often called the “wisdom years.” However, eruption time can vary—some people get them earlier, later, or not at all. These molars are the last teeth to develop, and because the jaw may not have enough space, they can grow in crooked, partially erupt, or remain impacted. Regular dental check-ups help monitor their development and prevent pain, infection, or alignment issues.

They are called “wisdom teeth” because they appear much later than all other teeth—typically during the late teenage years or early adulthood, when a person is considered more mature or “wiser.” The term reflects the stage of life rather than the function of the teeth. Since they erupt after the jaw and oral structures are fully developed, their arrival often requires professional evaluation to ensure they don’t cause overcrowding, discomfort, or dental complications.

Wisdom teeth can be healthy if they erupt fully, align correctly, and have enough space in the jaw. In such cases, they function like regular molars. However, many people experience issues like impaction, infections, cysts, gum swelling, or decay due to difficulty cleaning the area. Even symptom-free wisdom teeth may create hidden problems over time. Dentists assess their position with X-rays to decide whether monitoring or removal is the safest long-term option for oral health.
