Wisdom Teeth

Dear Readers,

My patients always ask me about wisdom teeth - if they are strong enough to withstand, should they be extracted as soon as they erupt?

First of all, I would like to say a few words about wisdom teeth. 
Third permanent molars are usually called WISDOM TEETH.
They are two in the upper jaw (also called a maxilla) and two in the lower jaw (also called a mandible).
They show a great variety of shapes and sizes as well as the number and shape of the roots. These teeth
erupt after 17, 18 years of age. Most adults have four wisdom teeth, but it is possible to have none, one, two, three or even more. 
I have seen many different cases related to the eruption of the third molars.

Sometimes the four, sometimes one, two or three of them appear. This depends on the space in the jaw and on their position. People with large jaws have no problems with the eruption, of course, provided the teeth are shaped and well positioned. Sometimes they  at a very late age. If they can not grow up properly, they are kept in the bone.

Wisdom teeth can partially erupt but also can become "impacted" - meaning that they do not fully "erupt " through the gums into the mouth. This can happen because there is not enough space in the jaw for the teeth, so they grow in the wrong direction. They also could be blocked by another tooth. If they are located horizontally in the jaw they can not grow up and often cause problems.


In my opinion, if the wisdom teeth are properly erupted and there is enough room for them in the tooth arch, if they do not affect the other teeth and bite, if they do not cause gum problems or abscesses, if they are easily accessible to be brushed and flossed properly, if they do not cause inflammation of the oral mucosa ( the lining of the oral cavity)- then it would be better if they remain in the mouth.

I have heard many patients say- " This is a wisdom tooth and I do not want it to remain in my mouth.”

I want to note something important here.

Sometimes wisdom teeth can be very important for the dental treatment. They could be used like abutments for the dental constructions. If the patient has wisdom teeth extracted, this can lead to a reduction in the possibilities of dental treatment at a later stage.

The problem comes mainly from the wrong maintaining of the area, as the wisdom teeth  are at the end of the dental arc, a lot of plaque is set and the decay begins. 

You can look at my post -  

Why Perfect Oral Hygiene Is So Important

Of course I get to the most important thing again - Perfect Oral Hygiene, which in this case is important both for the wisdom teeth and the overall oral health.

You can look at my post -  Advices To My Patients For Good Oral Hygiene

Dear Readers, when you feel any pain or inconvenience please visit your dentist. If wisdom teeth cause painful symptoms, surgical intervention may be necessary.

Dental examination and X-rays will be needed to allow your dentist to conclude if the wisdom tooth can remain or should be removed.

  1. Right, short but sweet knowledge shared on wisdom tooth extraction. Keep posting!

  2. Many people have their wisdom teeth removed under local anaesthesia by a general dentist or oral surgeon. This means that they are awake, but the area around the wisdom tooth is completely numb. Sedative drugs can be given with local anaesthesia to help people relax during the procedure. Well, thanks for sharing your knowledge. Visit Cinco Ranch Dentists
