When a person grows up, the teeth that will grow are called proximal root teeth.
Near-root teeth, medically known as wisdom teeth and third molars, are the last teeth in the mouth to erupt, one on the left and one on the left and one on the left and one (in the case of congenital absence).
Due to the continuous evolution and development of human beings, the gradual refinement of food has brought about the degeneration of the masticatory organs, resulting in the inconsistency between the length of the jaw and the required length of the dentition, and the proximal root teeth may be congenitally missing or have different degrees of impaction or eruption misalignment due to insufficient eruption position.
Impacted or misaligned proximal root teeth may result in the following:
1. Misaligned proximal root teeth can bite the oral mucosa, causing traumatic ulcers, long-term pain, and not easy to heal.
2. Food debris and bacteria accumulate between the impacted proximal root teeth and the anterior teeth (second molars), which can cause caries of the second molars, which can cause pulpitis, apical periodontitis, and even loosening and falling out.
3 The proximal root teeth that are tilted forward will also cause different degrees of resorption of the front teeth, resulting in caries, pain, and even inability.
4 The crown surface of the impacted proximal root tooth can be completely or partially covered by the gums, forming a blind bag, and food bacteria accumulate in the blind bag, which can cause pericoronitis of wisdom teeth, which is manifested as pain, swelling, and even difficulty in opening the mouth, and there are also symptoms of discomfort throughout the body.
5 In severe cases, the inflammation of pericoronitis of wisdom teeth can spread to the soft tissues, causing interstitial infection, facial swelling, and further formation of abscesses.
The age of proximal root tooth eruption is about 18 to 30 years old, and it is recommended that young people of this age go to a specialist hospital for examination, and if you have a proximal root tooth with impaction or misalignment, it is recommended that you have a preventive extraction.

The front teeth are not.
But wisdom teeth, the last molar, may come out much later.
The gums are easily inflamed when they come out, so be careful.

Generally speaking, people have two sets of teeth, baby teeth and permanent teeth. However, due to various reasons, sometimes baby teeth fall out late or permanent teeth erupt early. It is easy to make it difficult to distinguish between primary and permanent teeth.
Moreover, the order of tooth eruption is different, so people have the feeling of multiple tooth eruptions, you can go to the hospital to take a curved tomography to know if there are any teeth that have not yet erupted. About 70-80 yuan can be done.

Human teeth don't grow forever because tooth growth is controlled by the gums (periodontal). Gums are the soft tissues that surround the teeth, and it plays a limiting role during tooth growth. When the tooth grows to the limit that the gums can hold, the tooth growth stops.
In addition, as the growth and development of the human body gradually ends, the growth rate of teeth will gradually slow down and eventually stop. As a result, human teeth don't last forever.

People have two sets of teeth, baby teeth and permanent teeth in their lifetime. People begin to grow teeth from the age of 4-6 months, until the age of 13 or so, the teeth basically erupt, but between the age of 18-25 some people will grow wisdom teeth, which has a lot to do with genetics, some people have wisdom teeth and some people do not have wisdom teeth. Generally, you will stop teething at the age of 25, and since everyone's growth is different, it is not possible to say exactly how old you will be.
Baby teeth: are the first set of human teeth, with a total of 20 teeth. It begins to germinate from about 6 months after birth, and is basically full by the age of 3.
Permanent teeth: are the second set of human teeth, with a total of 32 teeth. From the age of 6, the baby teeth begin to fall out gradually, and the permanent teeth begin to erupt, replacing the baby teeth, except for the third molar, the remaining 28 generally erupt at about the age of 12.
The third molars erupt later, at the age of 18-30 years old, some do not erupt or partially erupt (all 4 in total).
Permanent teeth are the last set of human teeth, and after the permanent chain teeth fall out, there will be no more teeth erupting in the missing parts. This paragraph describes permanent and deciduous teeth, but ignores impacted teeth. In addition to baby and permanent teeth, there are a small number of people who have impacted teeth.
Impacted teeth are a cause of tooth deformity. It can displace the permanent teeth and can also be placed in the middle or behind the permanent teeth. If a permanent tooth falls out prematurely before the impacted tooth erupts, the impacted tooth replaces the permanent tooth.

Hello, this new tooth is wisdom teeth. There are two reasons for the deterioration of wisdom teeth: first, the size of the jaw has become smaller during the evolution of humans from apes, and there is no jaw space for wisdom teeth; Second, it may be related to oral hygiene, as it was not uncommon for young people in ancient times to have a few or most of their teeth to fall out.
And this is when the wisdom teeth that have just erupted will come into play. Modern dentistry is developed, everyone has the habit of brushing teeth, unless there is an accident, young people's teeth will generally remain intact, wisdom teeth will become redundant. Because there is no room for growth, wisdom teeth tend to be painful when they grow, and the position and orientation will be abnormal after eruption, and most people's wisdom teeth do not have the ability to chew and do not bite the teeth.
That is, wisdom teeth are generally redundant and are considered a trace organ.
Due to the special location of wisdom tooth growth, it brings many problems to its cleaning and self-absorption, and often causes diseases such as caries, periodontitis, and pulpitis.
Since wisdom teeth are in the innermost part, daily brushing is not easy to clean, and it is easy to produce tooth decay, and wisdom teeth often have swelling pain due to insufficient germination space, and will also invade adjacent teeth, causing toothache.

Wisdom teeth are a consequence of not fully evolving in the course of human evolution.

Hehe, it's wisdom teeth, this is also different from person to person, and some people will not grow in a lifetime.
Most men have almost finished growing by the age of 21, and a very small number of people can grow to the age of 23 and you still have room to grow taller. >>>More
Normally, wisdom teeth are grown in young adults aged 18-30 years. Due to human evolution, the length of the dental arch is smaller than the total length of the tooth, so that the last wisdom tooth cannot be covered or erupts incompletely, and the wisdom tooth is covered by the gums, which is easy to retain, and food debris is not easy to clean and become inflamed. Gum overlay can also cause occlusal trauma, inflammation and pain. >>>More
Yes, people are taller in the morning than at night, the spine is elastic, it becomes shorter when compressed, and when you stand for a day, the spine is compressed. The difference in height in the morning and evening is because if you rest for one night at night, the spine that has been compressed for a day will return to its original length. >>>More
