Finally, we mention the complications caused by it and the diseases caused by impacted wisdom teeth.

Definition of wisdom teeth

What we call wisdom teeth are actually molars. Molars are your toughest, widest teeth that grind food. There are usually four wisdom teeth in each person’s mouth. Some people naturally have less wisdom teeth. One at the top and one at the bottom on each side of the mouth. These teeth grow inside the bone like any other tooth. But they are the last teeth to grow.

Wisdom teeth begin to form when you are about 9 years old. These teeth form in a small cavity and grow inside the maxilla and mandible. First, the crowns of the wisdom teeth grow. Later, around the age of 14, these teeth are completed. Between the ages of 18 and 19, when the Tooth roots are almost formed, your wisdom teeth protrude through the bones and move into the mouth.

According to some theories our jaws have changed over the years due to changes in our diet.

Sometimes wisdom teeth are not able to come out. Let's examine the reason why wisdom teeth do not grow. We must first know how wisdom teeth grow.

Wisdom teeth growth

During the growth of wisdom tooth roots, the tooth in the bone moves slowly upwards, and only the crown part of the tooth enters the mouth. The root part is hardly fixed inside the bone. Up to nineteen years old, your jaw grows almost enough. Some jaws are large enough to allow wisdom teeth to grow.

As soon as the crowns of the wisdom teeth come out completely, this tooth can help you in the process of chewing. Therefore, it is not necessary to extract all the wisdom teeth.


Some of the symptoms of wisdom tooth growth are as follow:

  • You experience any tenderness or discomfort around the back of your mouth (on either side or just one)
  • You may notice swollen gum

The time to extract wisdom teeth

When you notice infection or cavities, it is time to extract the wisdom teeth.  Lesions (abnormal tissue) are another sign of the extraction time of this tooth.  Also when wisdom teeth damage to nearby teeth, you should remove them. Other signs can be:

Bone loss around roots and not enough room to brush and floss around the tooth.

Impacted wisdom teeth

We briefly mentioned that if there is enough space for wisdom teeth to enter: This tooth will grow naturally and can be placed in the oral cavity. But what if the wisdom tooth does not have enough space to come out?

The answer is that the tooth is trapped inside the bone, which is called the impacted tooth. The roots of impacted wisdom teeth are usually intertwined and curved. In this case, tooth extraction will be longer and more difficult. Note that the curvature of the roots is a principle or a rule, not an exception.

Sometimes some wisdom teeth are semi-impacted (partially impacted wisdom tooth). In fact, we consider a tooth whose entire crown is without gums and bones as a non-impacted tooth. Otherwise, we divide it into impacted and semi-impacted teeth.

Your tooth may be below the line gum. In such cases, you will usually need surgery.

How can a dentist identify a hidden wisdom tooth?

Your dentist or oral surgeon asks some questions about your dental symptoms and general health.

During an oral examination and radiograph, the dentist identifies the impacted wisdom tooth. In addition, dental X-rays can reveal the presence of impacted teeth. 

  • Treating your impacted wisdom may be difficult.
  • You may have medical conditions that increase surgical risks.

So please visit an oral surgeon to discuss the best course of action.

Impacted wisdom teeth can cause a number of problems.

  • Gum infection (or Pericoronitis)
  • Bone infection
