Baby Development, Baby Guide

When do permanent teeth come in

Regular checks by the dentist are essential – An exhausting procedure: In the first years of life, with the tooth breakthrough, 20 small teeth make their way through the gums.

This can sometimes be painful and lead to further complaints. The process is different for each child; not all have problems when the first teeth show.

Tooth development begins before the breakthrough

Already in the womb form the first approaches of the teeth in the jaw. Between around the sixth and eighth week of pregnancy, the toothed rack is created, from which later on the teeth pave the way. Still, during the pregnancy, the embryo deposits the minerals necessary for the formation of the tooth.

The tooth breakage

First, the teeth are hidden in the bar. Usually, the breakthrough begins between the sixth and eighth month of life of the baby. In the beginning, only small white tips appear, the roots form and the tooth crown continues to grow through the gums.

As a rule, the process begins with the two central incisors of the lower jaw, those of the upper jaw follow a little later. At one year, most children have broken their upper and lower incisors. The front molars are already developing, followed by the canines.

The jaw will now be larger, to give the deciduous teeth enough space. At 18 months, the front molars, at 20 months and the canines are completely visible.

At the end of their second birthday, the back molars finally paved the way for most children.

For other children, it takes longer; they only show their complete dentition at the age of three years. This is not worrying anymore: Like all developmental processes, tooth eruptions varies from child to child.

Teething problems

Even before the first tooth shows, there may be a painful pressure in the jaw. Also, redness and swelling at the break-through points are not uncommon.

Many children have red cheeks, and the outer mouth is sensitive, often sore. The diaper area may also tend to become sore.

Other symptoms occasionally associated with tooth eruption are altered stool – it may be fluid but also hardened.

A slight fever is also a common side effect. It can be seen that the tooth development very stresses the body, and the metabolism is running at full speed. This can also affect mental health in a weakened immune system.

The overall well-being of the child may suffer. As a result, restless sleep and screaming are the results. For parents, this means preserving the nerves and calming the child.

Comforting and cuddling creates closeness and helps to withstand the time. Other children, on the other hand, show little symptoms and tooth eruption occurs almost unnoticed.

Measures against pain and other symptoms

The pressure the baby feels in the jaw tries to counteract it. By putting any objects in your mouth and chewing on them. The pain becomes more bearable.

It often helps when the child bites on a cold object. Also, you can apply a suitable pain and anti-inflammatory gel on the gums, a doctor can make a recommendation.

If your child suffers from a sore bottom, relieve the discomfort caused by hygiene and ointments. Sabbert it a lot; it helps to wipe the mouth region again and again, so as not to irritate them unnecessarily.

Additionally, during this time, a small neckerchief may prevent the saliva from soaking the top of the child.

On restless nights, proximity to you is especially important. Your child needs care and security.

Slightly elevated temperature is no cause for concern. In case of higher fever, a visit to the doctor is recommended to clarify the cause. There may also be an infection that needs to be treated.

Dental care is important

Already the first teeth should be carefully maintained. The milk teeth function as placeholders; problems can affect the balance of the oral flora and the condition of the new permanent teeth.

Not every baby likes it when a toothbrush is being tinkered in his mouth. In this case, maybe a thimble toothbrush made of silicone, a rag or a cotton roll will help.

Think of little rhymes or toothbrush songs to distract you. In this way, brushing your teeth can quickly become a pleasure.

As soon as your child becomes independent, you can do little rituals of dental care. Another possibility is a game: the child is allowed to brush your teeth and vice versa. With you, it learns excitingly, how to properly care for your teeth : First, the chewing surfaces are cleaned, then the outer sides, then the insides.

Also, make sure you have a balanced, non-sugary diet to help reduce tooth decay. If you notice discoloration or changes to the enamel, you should consult a dentist.

Also, regular visits are recommended – these should take place once or twice a year.

The further development of the teeth

While the milk teeth are still working, the permanent teeth grow hidden in the jaw. First, at about the age of six, new molars break through. These have no counterpart in the childbirth and grow behind the milk teeth.

During the same period, the central incisors work their way. The roots of the deciduous teeth form more and more back until they have no more support and fail. In the resulting gaps grow the permanent teeth.

Thus, tooth by tooth, the new dentition breaks through until the baby teeth are completely replaced at 12 to 13 years. After all, there are more molars in the back, so that the change is complete – so the permanent dentition, unlike the deciduous dentition, has 28 instead of 20 teeth.

Some people later develop wisdom teeth behind the last molars. This often happens only in adulthood and is not always easy.

As with the deciduous dentition, the same applies to the permanent: careful dental care should be taken for granted and a balanced diet contributes to the health of the teeth. Regular checks by the dentist are recommended to be able to identify and correct any problems at an early stage.

You see, tooth development works according to a fixed plan, but not with the same speed at every child. Here again the development in an overview, whereby the age data can vary:

  • 6th month: middle lower incisors
  • 12 months: all incisors broke
  • 18th months: anterior molars
  • 20th months: canines
  • 24 months: posterior molars
  • six years: the beginning of the tooth change
  • 13 years: permanent dentition complete



  • With a sore buttock, cleaning with black tea, careful blotting with breast milk and applying an ointment with calendula can help.
  • Teething problems can be helped by cooling teething rings, violet root, herbal ointments, and homeopathy.
  • Special dental surgeries for children are especially recommended. Here, the children are taught the dental care, and the equipment of the practices are usually child-friendly.
