Should wisdom teeth be extracted?

The third molars in our mouths, traditionally called wisdom teeth, are the last teeth to come out, but not before the end of puberty, between 18 and 22 years old. The fact that they come out so late influences a lot their position in our.

Actually, the available space is practically inexistent, most of it being taken up by the already existing teeth, especially in the lower jaw, the bone being completely formed and very compact which constitutes a too big obstacle for it to be overcome.

The clinical conditions that we can observe are: abnormal teeth eruptions or non-eruptions (it partially erupts or it doesn’t at all because of the lack of space).

Abnormal wisdom tooth eruptions:

  • horizontally inclined: in this case the tooth’s crown is in direct contact with the tooth next to it, this leading to an area where food and bacteria get stuck and can produce cavities, inflammation and swelling of the gums around the tooth
  • laterally inclined: not being successful in finding enough space, the wisdom tooth grows laterally in relation to the neighbor teeth. In this case, they can be inclined towards the inside of the cheek or towards the tongue or the palate.
  • they determine the incapacity of these teeth to come in contact with their antagonists (the teeth on top of them), in order to become useful in the chewing process.
  • these kind of teeth don’t find the proper space for having a useful position in the mouth, cannot find the impulse to erupt and can usually be found in a bad position in relation to the bone and the other teeth, being totally or partially covered by gum and bone.

They provide the perfect conditions for numerous pathologies:

  • cavities: the tooth which is partially covered by gum becomes a natural recipient for plaque and bacteria; the tooth cannot benefit from the normal hygiene procedures because of its bad position.
  • the resorption of the root because of the contact between the wisdom tooth’s crown and the root from the neighboring tooth.
  • pericoronitis: is the inflammation which appears around the crown of a tooth which is about to erupt; this is a phenomenon specific for wisdom teeth and leads to the swelling and increase in sensitivity because of the inflammatory response, which appears as an effect of the bacteria which contaminate that area.

Did you know that the wisdom tooth represents about 98% of all non-erupting teeth cases and that 73% of all young people have at least one non-erupted wisdom tooth?

In our clinic we use an equipment which is usually used in neurosurgery, which helps to reduce the tissue loss to the minimum and also makes the post-extraction lesions very small.
