Dental surgery – FAQ
What are the indications for the third molars extraction?
Pericoronitis – the inflammation of the soft tissues surrounding the crown of the impacted tooth caused by the natural bacterial flora. During the temporary immunodepression the bacteria amount may increase causing the inflammation.
Periodontal disease – leaving the impacted third molar untouched may affect the bone surrounding the second molar and cause periodontal diseases. Subsequently this situation may cause gum recession, root caries and the instability of the tooth.
Caries – due to the position of the third molars, even if not impacted, they are very difficult to clean. The impacted third molar, which isn’t on its proper position, can be an even greater challenge for the patient.
Root resorption – the third molar impacted close to the second molar may cause the resorption of its root. It usually happens to patients aged 21-30.
Pathological changes – the tooth sockets of the impacted third molars may cause some tumours and cysts of dental origin.
What are the contraindications for the third molars extraction?
In case when the potential complications may exceed the advantages of the extraction – it should not be conducted. The main contraindications are: the high risk of adjoining structures damage, advanced age, uncontrolled cardiovascular system and respiratory system diseases, significant coagulopathy, immunodepression.
What is necessary for the impacted wisdom tooth extraction?
Before the impacted molar extraction procedure we always proceed with the X-ray image or tomography. We also check the patient’s medical history thoroughly.
Does the impacted tooth extraction hurt?
Absolutely not, the whole procedure is being conducted with local anaesthesia.
What is the most common position of the impacted molar?
The most common position of the impacted third molar is the mesial-angle position. In this case the mesial position of the third molar may be placed below the distal outline of the second molar.
The other possible positions are: the tooth impacted horizontally, vertically and the distal angle of the tooth, which is quite a challenge for every surgeon.
What stops the eruption of the third molars?
The main reason the third molar stops erupting from the jaw bone is the lack of space. It is also proved there is a genetic predisposition for the impacted tooth.
