All About Wisdom Teeth

Believe it or not, the term “wisdom teeth” (aka third molars) has nothing to do with knowledge or intelligence. Instead, the term refers to the fact that they emerge much later than baby teeth. If they erupt at all, they usually do so around age 18. Eruption may be straight, crooked, or impacted. But even molars that come in straight often need to be extracted. Extraction solves problems such as lack of space as well as the inability of many to keep them cleaned and maintained, since they are difficult to reach.  

Vertical Impactions

When the part of the tooth is above the bone and visible in the mouth, and part of it is submerged in the bone, this is called a vertical impaction. In such a case, the tooth could still erupt properly if the tooth next to is not in the way. However, if the upper tooth is fully vertically impacted, the entire tooth is submerged in the bone. And extraction is often necessary. In most cases, the dentist will evaluate whether the tooth moves over the course of several years. In most cases, if they move, the impacted teeth may need to be removed.  

Mesial Impactions

Partially lowered lower teeth are known as mesially-erupted. This means that part of the tooth is above the bone and visible in the mouth and part of it is submerged in the bone and is it tilted mesially, which means it is tipped toward the front of the mouth. This tooth will not likely erupt properly as the tooth next to it is in its way. These teeth typically need to be extracted because the bacteria that collects under the gum tissue make them difficult to clean. And poor hygiene can lead to infection. What’s more, the tooth next to the wisdom tooth can also decay due to the wisdom tooth.

Horizontal Impactions


When the tooth is perpendicular and will not properly erupt due to location, this is called horizontal. The dentist will observe such a tooth over a period of years, to determine whether they should be removed.
