Teeth are not only the key to a beautiful smile, but also vital for speech, chewing and overall health. Healthy teeth depend on a developmental process that begins in childhood and proper care habits. Therefore, knowing how teeth are formed, what stages they go through and what to look for during the development process is the first step to maintaining oral health throughout life.
Tooth development begins long before birth. The tooth formation process begins approximately from the sixth week of the baby's life in the womb. During this period, the first form of teeth, the tooth buds, differentiate from the epithelial tissue in the mouth and form. In approximately the fourteenth week, these buds begin to transform into hard tissues. During this process, the foundations of both milk teeth and permanent teeth are laid.
Although the baby's teeth are not yet visible in the mouth at birth, there are developing structures belonging to milk teeth in the jaw bones. For this reason, it is very important to pay attention to oral hygiene from infancy and to create a diet that will support tooth development.
Milk teeth are the first teeth to appear in children and usually start to become apparent from the 6th month onwards. Although the time of emergence may vary for each individual, all milk teeth are usually completed by the age of 2.5-3. There are 20 milk teeth in total, 10 in each jaw.
The lower central incisors appear first. Then the upper incisors, lateral incisors, first molars, canines and finally the second molars begin to appear. During this emergence process, babies may experience symptoms such as restlessness, increased salivation, itching, loss of appetite and sleep disorders.
Milk teeth should not be neglected, thinking that they are only temporary. Because these teeth play a critical role in the child's ability to eat properly, gain clear speech skills, guide jaw development and correct positioning of permanent teeth.
Milk teeth begin to give way to permanent teeth at the age of 6. This process usually lasts until the age of 12-13. The first permanent teeth to appear are usually the first molars, which are located behind the milk teeth. These teeth are the first permanent teeth to appear before the milk teeth fall out. After that, the front incisors, lateral incisors, canines, premolars and second molars erupt in order.
The eruption process of permanent teeth may vary from person to person. Nutrition, genetic factors and oral infections can affect this process. The last permanent teeth to appear are the third molars, which appear between the ages of 17-25. These are also known as "wisdom teeth" among the public.
Tooth development is not limited to just appearing in the mouth. The internal structure of the tooth also develops over time. This development is evaluated based on four basic structures:
Tooth development can be affected by many genetic, environmental and systemic factors:
Genetics: If there are conditions such as missing teeth, crooked teeth, and late tooth eruption in the family, similar problems may be seen in the child.
Nutrition: Especially during pregnancy, the mother's adequate calcium, phosphorus and vitamin D intake directly affects the baby's tooth development. Excess sugary and acidic foods in childhood weaken enamel formation.
Systemic Diseases: Diabetes, thyroid disorders, kidney diseases, hormonal problems and some genetic syndromes can negatively affect tooth development.
Traumas: Blows to the jaw and face in infancy or childhood can damage the developing tooth germs and cause the tooth to emerge with structural deformities.
Drug Use: Some antibiotics (such as the tetracycline group) used during pregnancy or early childhood can cause permanent changes in tooth color.
During the development process of teeth, conditions such as imbalance, crookedness, missing teeth or extra teeth can be observed in the jaw structure. If such developmental problems are detected at an early age, intervention is easier and more effective.
Orthodontic evaluation is usually recommended around the age of 6-7. During this period, the child's jaw structure, the condition of the milk and permanent teeth, and the closing relationships can be evaluated and possible problems can be determined at an early stage. When necessary, jaw development is guided with guiding appliances.
The teething process can be challenging for both the baby and the parent. The following symptoms are commonly seen during this process:
These symptoms are normal. However, if the fever exceeds 38.5°C, extreme restlessness or diarrhea becomes severe, a doctor should definitely be consulted.
Is it a problem if teething is delayed?
Some children may have genetically delayed teething. However, if no teeth have emerged by the 12th month, a dentist should evaluate them.
Should baby teeth be extracted if they are decayed?
No. Baby teeth guide the permanent teeth. Unnecessary extractions can prevent permanent teeth from emerging in the correct position. They need to be treated.
Do wisdom teeth emerge in every individual?
No. In some individuals, they may not develop at all or may remain impacted. Impacted teeth can lead to problems such as infection or jaw narrowing.
The formation and development of teeth is a complex and carefully monitored process that begins with the first cell differentiation in the womb and continues until young adulthood. A conscious approach to each stage of this process plays a decisive role in the child's general health as well as oral and dental health.
It is possible for this process to proceed smoothly with regular dentist check-ups, proper nutrition, hygiene habits and early orthodontic monitoring. Remember, the foundation of a strong smile is a healthy and developed oral structure.
