When do wisdom teeth grow?
The wisdom tooth (in common parlance "eight") is called the 8th, extreme tooth in the dentition, or the third molar. It got its name because it grows up last, when a person reaches intellectual maturity - becomes wise.
Many are sure that the appearance of "eights" does not depend on how old a person is. This is a misconception: the roots of a wisdom tooth begin to form at the age of 15-17, and the wisdom tooth itself grows on average up to 25 years of age . Sometimes it erupts a little later or a little earlier, and sometimes it does not appear at all. But if B and m have already turned 27 years old, and wisdom teeth yet, expect that one day they will be cut, just not worth it .
Patients of a more mature age who consulted the dentist, thinking that they were cutting a wisdom tooth, most often suffered from pericoronaritis. This is the name of the inflammation of the part of the gum, which, like a hood, covers the half-erupted tooth. Wisdom teeth: symptoms of growth

When to decide on deletion?
Every person in adulthood is faced with the growth of third molars - the extreme "eights" of the upper and lower jaw, the process of eruption of which is often accompanied by unpleasant sensations. This is due to the fact that the wisdom tooth begins to come out at the age of 20 to 28-34 years, when the period of development of all organs in the human body ends, as a result of which it has to pierce hard and soft tissues. Today, the teeth-eight do not perform any practical role, having turned into rudiments. For this reason, when a wisdom tooth grows, dentists recommend removing it .
Features and difficulties of third molars
Speaking about what a wisdom tooth is, many doctors note not only their uselessness, but also a certain danger, since they often become the causes of dental and orthodontic diseases. For a better understanding, their main features should be highlighted, which will be useful for everyone to learn about:
do not have precursors in the form of "milk" molars;
often grow abnormally, crooked and uneven in relation to the rest of the molars;
have a curved root structure, which are often intertwined;
with growth, a sharp or dull pain in the jaw is recorded.
It is interesting to note that in 25% of cases they can be impacted, that is, they do not erupt, but remain forever in the bone tissue. The partial appearance of the last molars is also the norm, since everything happens individually, depending on the genetic predisposition of the body of a particular person. Unfortunately, most often, when a figure eight tooth is cut, a person experiences discomfort, pain and even swelling, which requires an immediate visit to the dentist.
Indications for preservation
A decision on what to do with wisdom teeth should only be based on the recommendations of the attending dentist, who, on the basis of an X-ray or MRI, determines the position of the molars and the characteristics of their growth. They can be left under the following circumstances:
even and correct growth;
there is no pressure on adjacent molars;
the doctor can get to them for the prevention and treatment of caries.
Unfortunately, this does not always happen, because, taking into account the peculiarity of its location, almost always a wisdom tooth is cut, hurts and grows crookedly, putting pressure on neighbors and causing inflammation of the gums . Pain and bad breath are not the only troubles that a person can face during such a process. Of the main pathologies allocated when a wisdom tooth climbs, the following are noted:
inflammation of the trigeminal nerve;
pericoronitis (inflammation of the gum tissue) and dystopia (malocclusion);
the formation of a "hood" in which food particles remain, leading to caries;
sinusitis due to the penetration of infection into the maxillary sinuses.
If a wisdom tooth grows, symptoms include not only pain, but also severe swelling, nasal congestion, chills, bleeding gums and fever, you should immediately see a doctor. To relieve inflammation, ointments and gels are often used, as well as antiseptic drugs - furacilin and ibuprofen, which prevent the penetration of bacteria and infections.
When to decide on deletion?
Answering the question that interests many people about how much a wisdom tooth grows, it is worth noting that this process can occur from 3-4 months to 1.5-2 years from the moment of activation. It is not worth making a hasty decision on removal right away, since you should find out how correctly it grows and whether there is pressure on the adjacent molars. Indeed, often, when wisdom teeth grow, it is possible to do without surgery, using only symptomatic treatment in the form of antiseptics and pain relievers.
However, in any case, you need to make a decision based on the recommendations of your attending dentist, since it all depends on how the wisdom tooth grows. Along the way, it is worth noting the contraindications for removal:
early and late pregnancy;
period of exacerbation of cardiovascular diseases;
a strong weakening of immunity due to chronic ailments;
the presence of a viral infection in the acute phase.
Based on the above, we can conclude that when wisdom teeth grow, the process must be constantly monitored, for which a dental office is visited at least 2 times a year. This allows not only to see the process of development of third molars, but also in case of deviation, to quickly make a decision on their removal . If a wisdom tooth grows, the gum hurts and swells, you should make an appointment with a doctor as soon as possible to diagnose and make a decision about the molar.
Why does a person need wisdom teeth?
We inherited the teeth of wisdom from our distant ancestors, who ate mostly hard and tough food. It took powerful jaws to chew. Over time, the nutrition of humanity has changed. Today we consume a lot more thermally processed foods. The "softening" of the diet led to the fact that the "eights" lost their original function, and the jaw itself decreased. In the modern world, primary adentia of the third molar is increasingly observed, that is, a situation when the rudiments of wisdom teeth are not formed .
According to statistics, approximately 92% of adults have a maximum of wisdom teeth provided by nature (that is, four pieces) . In 25% of humanity, third molars remain under the gum. And in about 8% they are not observed even in the embryonic state, which indicates not pathology, but just an individual characteristic.
A significant part of modern scientists believe that large extreme teeth are a useless rudiment that creates too many problems, and the best solution is to remove a wisdom tooth at the initial stage of its formation. However, experts note the useful functions of the "eights". For example, they protect adjacent teeth from loosening and gaps in which food can accumulate. In addition, it is to the large extreme teeth that a bridge is sometimes attached.
What complications can wisdom teeth cause?
Most often, wisdom teeth grow with complications . They can move, be tilted or not erupted completely, causing inflammation of the bone and gums, disrupting the bite, injuring the inner surface of the cheek and destroying the teeth with which they come in contact.
The main reason for complications is a small jaw that simply cannot fit the maximum number of teeth. It is the lack of space that causes crowding of teeth or their retention (semi-eruption). Third molars are born when the growth of the jaw bones gradually fades away. Therefore, wisdom teeth simply have nowhere to grow.
The eruption of a wisdom tooth, in addition to general discomfort (pain, swelling of the gums, fever), in 80% of people provokes purulent inflammation , which can pose a real danger to health and life. The gums around the cutting wisdom tooth take the shape of a hooded pocket, under which plaque, food debris and bacteria accumulate (see Fig. 2). This causes suppuration and an unpleasant odor.
In addition, third molars occupy the last, most inaccessible place on the jaw and are often poorly cleaned during hygiene procedures. This contributes to the development of caries, which often spreads from wisdom teeth to other teeth.
In order to prevent complications associated with wisdom teeth eruption and bite, I strongly recommend visiting an orthodontist - he specializes in bite correction.
Wisdom tooth: remove or treat?
If the third molar has grown correctly and is only affected by caries, it may well be treated. Although the inconvenient location makes it difficult to treat a wisdom tooth. In case of more serious complications, it is better to discuss the appropriateness of treatment with a doctor.
Should wisdom teeth be removed? If there is no room in the jaw for one more tooth, the third molar will have to work its way, crowding competitors (adjacent teeth). This means that complications are inevitable. In this case, the best way out is to remove the wisdom tooth.
Remember also that a wisdom tooth during pregnancy can be removed no earlier than the 13th and no later than the 32nd week. It is during this period that the mother's immunity is maximal, and the risk to the fetus is minimal. Nevertheless, the best option for a pregnant woman is regular visits to the dentist and prevention of possible problems (including with wisdom teeth).
Can Wisdom Teeth Problems Avoid?
Of course you can. To do this, it is enough to go to the dentist for a professional hygienic procedure once every six months and for a preventive examination once a year. If you are worried about a wisdom tooth, your gums are inflamed, or your doctor has discovered problems with the "eights" at an early stage, follow his recommendations and be healthy!
