What are the teeth of wisdom used for?
Should they be kept or removed? For many people, wisdom teeth are a real concern. Communication will be devoted to them during the congress of the French Dental Association, November 22, 2016, in Paris. Dr. Jean-Marc Galeazzi, a dental surgeon, specializing in oral surgery, answers our questions.
What is the use of wisdom teeth?
They were more useful in the days of our grandmothers when they could serve as a relay when we lost our teeth. Today, dental hygiene is much better. There is less tooth loss. The tooth of wisdom no longer has much use. Also, the jaw has tended to become vertical during the evolution of man. The lower jaw is reduced and leaves less room for wisdom teeth.
At what age do they appear?
They grow between 18 and 25 years. However, the germ is present from the age of 11 or 12 years. As part of orthodontic treatment, to align the teeth, some orthodontists demand that they are removed between 15 and 18 years of age. It is better not to wait for the teeth of wisdom to shake the other teeth. I often recommend having a dental panoramic view around 15-16 years to see how they position themselves and if they come out correctly.
What is the justification for removing them?
If a wisdom tooth is incorrectly positioned, it can damage other teeth, cause a carious lesion of the last tooth, or problems with the gums. In principle, everyone has four wisdom teeth. However, some people have only one, two or three. I even saw a patient who had ten, but it is very rare. If one or two teeth grow, but not their antagonists on the other jaw, this can hinder the occlusion. It is also a reason for extraction. Finally, if the wisdom teeth grow painful, it is better to remove them.
Is the extraction painful?
We are in 2016, and we have effective anesthetics. Extraction will not cause pain. Local anesthesia should be given priority over general anesthesia, which was practiced ten or twenty years ago. After the procedure, the patient may experience discomfort for 48 hours, but the pain is relieved with conventional medications.
Can there be any consequences for chewing or even digestion?
No, extracting wisdom teeth has no consequence. The only problem during surgery would be to touch a nerve. However, this one is spotted by carrying out a radio before the intervention. To remove wisdom teeth, it is safer to speak to a dental surgeon specializing in oral surgery.
What is the ideal age for removing wisdom teeth?
If they are poorly positioned, it is better to intervene between 17 and 20 years, when the roots are not yet entirely formed. Afterward, the suites will be more complicated.
