Do you know How Teeth Changes Over the Age? A feature of the human body is the presence of two sets of teeth: milk and indigenous. Moreover, the first set changes even in the growing-up period, in childhood. No matter how strong and healthy the dental units are, they are characterised by ageing like any other organs. The acceleration of this process occurs under the influence of external and internal adverse factors. As a result, all jaw structures lose their functionality, attractiveness, and shape. Moreover, all tissues age: solid (enamel, dentin, cement), which serves as protection, and the pulp located inside, which has many blood vessels and nerve endings and supplies all other elements with nutrients. Specialists of the dental clinic “Dentika” will tell you how long our Teeth Changes grow,
Dental units begin to develop in the womb. Approximately at the 8th week of pregnancy, the oral cavity and the plate are formed, on which the embryos of the milk bite appear. By the fourth month, the cells are dividing. Are formed:
- Enameloblasts responsible for the formation of enamel;
- Dentin oblasts are the basis of the structure of dentin.
By the end of the second trimester, the inner and outer dentin layers are formed, and covered with tubules. Already formed bodies consist of:
- From the crown – walls, and neck;
- From the root – a site located in the gum, providing reliable fixation and nutrition.
The visible part has an enameled surface. It performs protective functions – it protects the pulp chamber from external aggressive influences. It depends on the state of the latter whether a sufficient amount of useful substances will enter the tissue. It also contains nerve fibers that go into the root system. Therefore, if inflammation begins in it or it is damaged, inevitably a person will begin to experience pain.
From the point of view of histology, age-related changes in the pulp, and the shape of Teeth Changes in humans are completely natural processes. All structures are subject to this, which indicates complex aging. When exactly this starts to happen depends on the individual characteristics of the organism and some other factors.
How long do dental units grow
As mentioned earlier, their growth begins even during the formation of the fetus. However, this takes place within the tissues. Their eruption is observed approximately 6-11 months after the birth of the child. By 2-3 years, as a rule, a complete milk supply is formed. In this case, the root is under the temporary set. They are separated by a small partition, which eventually collapses.
The change of bite to a permanent one occurs in the following order:
- Central incisors on the upper and lower jaws – 6-7 years;
- Lateral – 7-8;
- 1st molars – 9-11;
- 2nd molar units – 10-12;
- Fangs – 9-12.
Thus, everything is completed by the age of 13. However, at a more mature age, the so-called wisdom Teeth Changes can still begin to develop. This is observed from 18 to 30 years, possibly until a later date.
Note! The root set is formed longer than the milk one, as it must fulfill its functionality until the end of a person’s life.
How do jaw tissues develop in humans?
The process of forming a permanent bite occurs in several stages:
- Intramaxillary. The chewing organs, which remain with us and do not change, appear based on the plates that form inside the pits from the squamous epithelium. Approximately in the fifth month of embryonic maturation, an enamel coating appears along the lower edge of the rudiments of temporary units. As the mesodermal parenchyma grows into it, papillae and sacs appear. In total, 20 rudiments for the formation of replacement molars are located on the upper and lower jaws. 16 of them are already present at birth. The remaining 4 occur in the 5th year of life. Being in the same alveoli with milk, after a certain period they are separated from them by a bone septum and placed in their holes. The dental plates grow in a posterior direction. Dentin, pulp, enamel, blood vessels, and nerve fibers are actively developing.
- Teething. With the correct development of the jaws, a permanent bite is formed together with the loss of temporary units. The molars erupt in the same sequence as the predecessors. In some cases, problems with resorption may require the removal of precursors. The decision on this should be made only by the dentist after examining the child. Be sure to take into account the genetic predisposition and characteristics of the patient.
- Formation of periodontium and roots. This stage begins immediately after the appearance of replacement structures. At this stage, the complete formation of the root system occurs. At the same time, the coronal part is already practically formed and ready for active mineralization. Teeth during this period also go through several phases: intensive growth in length, development, and fastening of the apical part of the root, the unclosed tip of the root processes, the formation and fixation of the periodontium, and the completion of tissue formation.
- Stabilization. This stage is the final one. The jaw row is fully formed and ready for the chewing load. It is believed that the process is completed when the roots stop growing.
For reference! Many people wonder why a Teeth Changes occurs in childhood, and for what reason people are not born immediately with a permanent set. The fact is that nature has laid it down so that temporary molars, incisors, and so on are small in size to fit in the small, not fully developed jaw of a child. As they grow older, it develops and becomes larger, but the jaw units cannot grow. That is, they remain the same as before. That is why they are replaced by indigenous, larger chewing organs.
Until what age does the formation of dental structures continue?
Milk teeth in children in the amount of 20 pieces are completely hatched by 3-4 years. Change to a permanent bite begins at 5-6 years. However, it all depends on the hereditary predisposition and the individual characteristics of the organism.
Note! If the time has come for tooth loss, but this is not observed, do not immediately panic. Make an appointment with experienced specialists at Dentika Dental Clinic. They will conduct diagnostic measures and determine what to do next. Many parents believe that since temporary dental units will soon fall, it is not necessary to treat them with various lesions if the baby does not experience pain and discomfort. However, this is a big mistake. Without therapy, the inflammatory process spreads inside the gums to permanent structures that are still inactive. It is also important to teach oral hygiene from an early age to avoid problems in the future.
The development of the indigenous chewing organs lasts much longer than the milk ones. Usually, the bite is considered to be fully formed by the age of 13-14. However, then wisdom Teeth Changes may begin to erupt. Moreover, they appear at 18, 30, and even 40 years old. And some people don’t have them at all.
How jaw growth changes with age
Immediately after the eruption, both temporary and permanent teeth become vulnerable to the environment. However, their protection is provided by saliva, which saturates the structures with the nutrients necessary for normal development, and also destroys pathogenic microorganisms.
The first age-related changes are observed in the enamel coating and dentin. Due to the abrasion of the enamel, the masticatory organs gradually decrease in height (by an average of 0.035 mm per year). However, due to individual characteristics and the presence of bad habits, this can happen faster. In addition, the enamel surface also changes its shade. This is because it can accumulate dye in itself, due to which it turns yellow and loses its original luster. Cracks and microdamage often form on its surface. Remains of food get into them, and plaque forms. After a certain period, it mineralizes and prevents the penetration of minerals and other nutrients.
Note! The enamel coating does not self-repair. Therefore, if defects appear, you should immediately contact your dentist to prevent the development of complications.
Dentin can self-heal. However, this process slows down significantly with age. In addition, the quality of the replacement structure becomes much worse.
Age-related changes in dental pulp
The aging of the pulp chamber has a direct impact on dental health. When it ages, it decreases in volume. In addition, a pathological condition can be observed in which an abnormally excessive growth of connective tissue occurs with the appearance of scars.
Mineral deposits adversely affect blood vessels and capillaries. Atherosclerosis often develops. This disease is more susceptible to people over 50 years of age. Because of this, the dental units do not receive enough nutrition and become fragile and vulnerable to external aggressive factors.
It is almost impossible to estimate the age of teeth “by eye”. It is possible to determine it more or less accurately only during a medical examination. This is because their appearance is an individual feature of each person. It depends on what kind of lifestyle the patient leads, whether he observes hygiene rules, how he eats, and so on. For example, in young people, the masticatory organs can be in even more deplorable condition than in older people if they are not monitored.
Bone and gum tissue changes
With age, not only dental units change, but also bone structures. They lose their density and decrease in height. Osteoporosis of the jaw is often diagnosed in elderly patients. This is a systemic disease in which the bone loses its strength. As a result, pathological fractures are formed. According to WHO data, this pathology ranks 4th in terms of prevalence among dental diseases of a non-infectious nature.
The situation is aggravated by partial or complete dementia, which can develop even in young people (loss of several or all units in the dentition). In this case, the mandatory installation of prostheses is required so that the quality of life does not suffer. Moreover, they must be of high quality and installed with strict adherence to technology. Otherwise, the chewing load will be unevenly distributed, which will lead to pathological changes in hard and soft tissues. If you need prosthetics, contact Dentika dentistry. We have experienced specialists who will carry out the procedure correctly, which will avoid complications in the future.
Age-related gum recession can also occur. It manifests itself both against the background of previous diseases (for example, periodontitis), and because of poor genetics, an unhealthy lifestyle, and the presence of bad habits (for example, smoking). If you start this process, the dental units will begin to loosen and fall out.
Is it possible to slow down the Teeth Changes?
Ageing is a natural phenomenon that no one can avoid. However, this does not mean that in old age it is impossible to maintain functionality and aesthetic appearance of Teeth Changes. To do this, you need to follow a few simple rules:
- High-quality daily oral hygiene. It is necessary to use a brush and paste twice daily – in the morning and evening. It is not recommended to do this more often since the enamel is erased during the procedure. You can use special mouthwashes and dental floss to freshen your breath or remove food particles after eating.
- Regular visits to the dentist. Even if nothing bothers you, you should visit the dental office at least once every six months for preventive purposes. Periodically it is recommended to undergo professional cleaning to remove plaque and stone to prevent the development of caries. Remineralisation will preserve the protective functions of the enamel and protect it from premature erasure. Laser and physiotherapy are also beneficial. They strengthen the gums.
- Balanced and rational nutrition. The diet should contain a lot of foods enriched with vitamins and minerals (meat, fish, vegetables, fruits, herbs, dairy products, and so on). However, the intake of nutrients with food is not always enough. Therefore, after consulting a doctor, pharmacy vitamin-mineral complexes should be taken periodically. Remember that a surplus of nutrients is no less harmful than a deficiency. Therefore, we do not use any drugs on our own without the appointment of a specialist.
- Healthy lifestyle. As mentioned earlier, bad habits hurt all structures in the body, including dental units. Therefore, smoking, and excessive alcohol consumption are recommended to be completely abandoned.
- Timely treatment of concomitant diseases. If you have any dental problems, you can not let everything take its course and try to get rid of them at home. This may not only not give a therapeutic result, but also aggravate the situation.
Compliance with these simple rules will not only allow you to maintain health but in general, will have a positive effect on all organs and systems of the body. Therefore, they should become your daily habit.
Unfortunately, the natural ageing process of Teeth Changes cannot be avoided by anyone. However, it is in our power to maintain a beautiful and healthy smile for as long as possible. Specialists of dentistry “Dentika” told at what age milk and molars begin to grow, until what time this happens, when a change of bite begins in a person. Each stage has its time interval. Minor deviations in terms are not a reason to sound the alarm. However, in any case, it is recommended to make an appointment with the dentist. This will allow us to identify violations promptly and select an effective treatment regimen, preserving the beauty and health of the dentition for as long as possible. Do not forget about preventive measures that will help you avoid many dental problems!
