Best Tips On Wisdom Teeth: In Which Cases Should They Be Removed?
Wisdom Teeth The belief that wisdom teeth have no function and that it is therefore better to remove them is widespread in the population. However, “extraction is not justified when they are erupting correctly or have already taken their place in the dental arch,” says Olalla Argibay, member of the board of directors of the Spanish Society for Periodontology and Osseointegration (SEPA).
“Generally, these pieces begin to emerge between 17 and 25 years, although their appearance may be delayed. Sometimes the wisdom teeth come out without causing any problems and are fully functional. It is also possible that these will not develop directly. However, on many occasions these are teeth that usually present complications, ”according to Manuela Escorial, a dentist at the Sanitas Dental Healthcare Department. In this regard, Argibay comments that although “they usually leave around the age of 20, an evaluation of their development must be made because they may have an inclined eruption path that can interrupt their exit and, therefore, it will be necessary to assess whether or not it will be necessary to extract them ”.
“When a wisdom tooth is coming out, you usually notice a feeling of pressure in the back of the jaw that, sometimes, increases when biting. In these cases an analgesic or anti-inflammatory can be taken, but it is necessary to go to a dentist to evaluate the route of eruption of the grinding wheel since if there are any obstacles along the way, such as the root of the adjacent tooth, the grinding wheel will not completely erupt and its extraction must be valued, ”says the member of the SEPA board of directors.
In this sense, Escorial adds that “the most frequent symptoms associated with the exit of the wisdom tooth are: bleeding when brushing in the area, inflammation and, in some situations, pain. Thorough hygiene, dental examination and prescribed therapy with pain relievers or anti-inflammatories are usually enough to control a condition that can be repeated in the progressive attempts of the tooth in its eruption ”.
The Sanitas Dental expert warns that “there is a widespread belief about the need to take antibiotics if they disturb the wisdom teeth. Our health will thank us to avoid this type of drugs if there is no objective infection. To prevent infections in the area where the wisdom tooth tries to erupt and where the accumulation of food remains is frequent, we will carry out rigorous hygiene using the means at our disposal (brushing, rinsing and the use of an irrigator) ”.
Both dentists stress that wisdom teeth should be justifiably removed and their preventive removal is currently not indicated, especially when they are erupting correctly or have already taken their place in the arch. Escorial stresses that a review and evaluation by a dentist is necessary to establish a correct diagnosis. Its extraction will be indicated in those cases where in its attempt to exit they cause caries and reabsorptions in the adjacent molars, repetitive infections or problems in the attached soft tissues because their exit is anatomically impossible.
Cases where they cause alterations in the occlusion (bite) or that may condition a recurrence (or relapse) after orthodontic treatment may also be indications for its extraction. Argibay adds to this list the cases in which the pain caused by an anomalous eruption in which the molar is impacted against the adjoining tooth causing the eruption to be interrupted and may generate the inclination of the teeth of the arch. “The success in the management of wisdom teeth is based on the individualization of each case and the periodicity of oral examinations,” says the specialist of Sanitas Dental.
Normally, says Argibay, when it is necessary to do the extraction of the wisdom teeth, it is usually done on the same side of the mouth in one or two sessions. Extracting only one can cause the opponent to continue erupting or modify its position, which may eventually contact the gum in that area. The extraction of all four is usually justified when the eruption pathways are not ideal and the teeth are inclined or supported on adjacent ones.
“Wisdom teeth are more prone to cavities for various reasons. Their posterior location and the position in which they may be may make brushing less effective. They are often affected by caries during the eruption process, where brushing is even more complicated. If the molar is going to remain in the mouth, the caries should be treated like any other tooth ”, Escorial responds.
Argibay details that “when the wisdom teeth are partially erupted and the gums cover them only partially, it is common for bacterial plaque to accumulate due to the difficult access of brushing, increasing the risk of caries. In those cases in which there is no opposite tooth or it has large cavities and the rest of the molars are present, its extraction is usually recommended. ”

“The extraction of wisdom teeth is usually easier at young ages, since the roots are not usually fully formed. But we must make sure radiographically of the position of the rest of the anatomical conditions prior to any dental extraction, no matter how simple it may seem to us, ”says the SEPA spokesperson.
On the day of surgery, avoid eating hot or hard things, rinse or brush your teeth. It is important to comply with the guidelines of the medication that is prescribed, especially pain relievers and / or anti-inflammatories and antibiotics.
“Like any surgical intervention, it involves a recovery period during which the patient can experience pain, inflammation and bleeding. These symptoms are usually maintained for three or four days after the extraction and their intensity will depend mainly on the duration of the intervention, the complexity of the extraction and the position of the wisdom tooth ”, summarizes Argibay.
If we divide the upper and lower dental arches by the midline, we obtain four quadrants. In each quadrant we find an anterior group, formed by the central incisor or palette, the lateral incisor and the canine or tusk. These three teeth perform functions of cutting and tearing the food, in addition to being our letter of introduction and responsible for the production of many speech phonemes. After this previous group we find that the “crushing” surface of the teeth increases. Two premolars and two or three molars grind and prepare the food together with the action of saliva to form the food bolus, essential for proper digestion. The wisdom tooth is the third molar and if its eruption and the relationship with its antagonist (opponent) tooth are correct, it is one more tooth, fully functional.
The Sanitas Dental odontologist points out that the progressive transformation of the human diet towards more processed foods where so much chewing is no longer necessary has conditioned changes in the muscles (less powerful), the maxilla and the jaw (smaller size) and, to a lesser extent. less teeth.
“The lack of space for the wisdom teeth is explained, among other factors, because the speed at which bone size is reduced is greater than the size and number of teeth. This is the reason that wisdom teeth currently cause problems with their eruption and in certain situations their extraction is necessary, “concludes Escorial.
