Absence of wisdom teeth
They are called wisdom teeth or third molars. Some people do not have all of their wisdom teeth. There are theories that explain that the jaws have shrunk over the years due to changes in diet, thus reducing the space for them to erupt.
Why are wisdom teeth removed?
One of the main reasons for removing wisdom teeth is not having enough space to erupt. For this reason they tend to erupt crookedly or can remain inside the jawbone due to lack of space.
In addition, as they occupy a very posterior position, they cannot be brushed properly and can cause gum inflammation or even cavities.
Wisdom tooth problems
The most common problems related to wisdom teeth are:
- Infection or caries
- Damage to neighboring molars or second molars (mainly caries)
- Not enough space to brush and accumulate dental plaque.
Some dentists recommend extracting them before they can cause problems in the future.
It is also often recommended to remove them before starting orthodontic treatment, to make more room for the rest of the teeth.
Sometimes wisdom teeth do not fully erupt. Bacteria and plaque can accumulate around the tooth that is partially out and this causes inflammation of the gum called pericoronaritis, which makes it necessary to consider its extraction as well.
We recommend an annual check-up with your dentist. By means of an orthopantomography he/she will know if there is a bad position of the wisdom teeth and if they are producing any interference.
In specific cases a mandibular CT scan can be requested to see if the lower wisdom teeth are close to the dental nerve and assess the risks that may exist if it is decided to extract them.
If you have discomfort caused by wisdom teeth request a visit with your dentist to clear your doubts.
Extraction of wisdom teeth
As we have said before, it is important to previously assess the position of the molars by means of orthopantomography and mandibular CAT scan if necessary, and to see the risks that their extraction may entail.
The complexity of the extraction depends fundamentally on the position of the teeth.
Usually they are not complicated extractions, as long as they are performed by a maxillofacial surgeon.
For two or three days after the extraction there may be discomfort and you may have to take an anti-inflammatory or analgesic.
It is recommended not to rinse or brush your teeth during the first 24 hours after the extraction.
