Approximate time of the eruption of milk teeth

terms of milk teeth eruption in children

For most kids the process of eruption of milk teeth begins at about six months. However, for many reasons, beginning of the eruption could shift towards a reduction or increase in the age. In the not too frequent cases, children can be born with teeth already, and sometimes first appear only after the first year of age.

Any time periods may be due to different reasons, among which there are pure physiology and heredity, or dangerous disease. Almost always a slight delay in 2 or even 4 months does not mean anything.

But it is better to conduct a complete examination than conventional pediatric examination to exclude the possibility of diseases and pathologies.


There is quite a big difference in the structure of milk teeth and molars. Milk teeth are smaller, they have a much thinner layer of dentin and enamel, some other shape (more rounded), incisors are more prominent. Pulp has larger volume and the channels in the roots are wider, which often leads to the ingress of bacteria and infections.

All kids differently tolerate teething. For some, it is almost painless, without causing any trouble to the kid, without becoming another reason to worry about for parents.

However, for most it is still characterized by several symptoms, sometimes very unpleasant, which can determine that the process is running in the body.

Common symptoms

  • Sudden mood swings, constant whims.
  • Sleep impairment due to the fact that the baby is experiencing discomfort.
  • General malaise and anxiety.
  • Refusal to eat. If the diet includes partly solid food, the child may no longer react to it. If breastfeeding is continued, then there may be a more frequent urge to eat as sucking movements may reduce the discomfort.
  • Constant desire to “pull” in the mouth all the items that came to hand.
  • Increased salivation, as a way to soften and moisturize the gums.
  • A runny nose in the form of a clear liquid, which does not bring anxiety to the child. It can occur during the growth of the upper front teeth.
  • Increased temperature, sometimes up to 99 °F and even 102 °F. It can stay at the same level for several days (2 to 5) or change abruptly. Therefore, there is a need for continuous monitoring and subsiding, if it is too high.

Local symptoms

symptoms of dentition

  • Small puffiness and swelling in the places where first teeth have to erupt.
  • Redness of the gums.
  • Itching and pain when pressing and without it.
  • General inflammation of the gums, which is not sharp and should not cause anxiety for parents.

Table of teeth growth among children

Besides timing, of a great importance is an order in which teeth start erupting.

A significant deviation from the normal sequence of teeth eruption should always be noticed by parents. In this case, you need to consult a specialist.

The tooth number in the order of its growth (number within the brackets – is a numeration of the teeth in dentistry) Average statistical terms of teeth growth
Lower central incisors – 1 (31, 41) 5 – 7 months
Upper central incisors – 2 (11, 21) 7 – 9 months
Upper lateral incisors – 3 (12, 22) 8 – 11 months
Lower lateral incisors – 4 (32, 42) 11 – 13 months
Upper first molars – 5 (14, 24) 12 – 15 months
Lower first molars – 6 (34, 44) 12 – 15 months
Upper cuspids – 7 (13, 23) 15 – 18 months
Lower cuspids – 8 (33, 43) 17 – 20 months
Lower second molars – 9 (35, 45) 23 – 30 months
Upper second molars – 10 (15, 25) 23 – 30 months

This is a full milk teeth occlusion, which is formed in the child. It consists of only 20 teeth – five pieces at each quarter. They usually fall out between the 6-7 years of age already. Sometimes a loss begins a little earlier or later.

Milk teeth are very much susceptible to a caries process, so it is possible that before the term of their loss a dentist will remove them.

Possible problems

In most cases the anxiety of parents who feel that they have noticed a pathology of their child, it is unjustified and in vain. Dads (and especially moms) are beginning to really worry if the neighbor’s kid of the same age already has 3 teeth, and their favorite boy has only one.

Not taking into account the difference in normal development, gender, and heredity, they begin to be a reason of a groundless anxiety.

Parents should be worried if the following abnormal phenomena will be observed:

  • Strong delay of first teeth – more than 3 or 4 months.
  • Much earlier eruption process, when the teeth start to appear on the first and second month of the life of a baby.
  • A substantial disorder of the correct order of cutting teeth.
  • Non-eruption or absence of one or more teeth.
  • Teething in a place where it should not be, beyond the right arc for the intended line of dentition.
  • Wrong and an abnormal process of formation of dentition.
  • If a baby is born already with a number of teeth, as when teething begins even before birth.

Factors affecting the terms

how quickly the baby teeth eruptAll of these factors can be divided into two large conditional groups. First, come those which detain eruption, and the second – those which accelerate.

What can delay the process of eruption and growth

  • Severe infectious diseases.
  • Relatively long malfunction of the gastrointestinal tract, including dyspepsia.
  • Pituitary insufficiency (pituitary disease). It may be a consequence of complex infectious processes.
  • Rachitis (vitamin D deficiency).
  • Child’s body metabolism disorders. There may be inborn disorders.
  • Heredity (genetic factor).


  • Acceleration.
  • Child’s gender. Girls eruption begins somewhat earlier.
  • Climatic factor. In the southern region, the process can begin earlier due to a hot climate.
  • Some endocrine disorders.
  • Very rarely – growing tumor.

What if it happens not in time?

There is no clear answer to this question. More often there is no need to do anything. Delay and acceleration of teeth eruption for several months should not cause too much concern from parents.

The fact is that all of the terms referred to pediatricians and dentists, are very relative. Better even to call them as a guidance. They are necessary to a greater extent in order to enable parents to prepare for the beginning of the process and not to be nervous.

Approximate dates are determined by the average, which cannot be taken into account for all possible factors of influence: neonatal, physical and psychological, individual (family history, gender, acceleration, etc.), territorial and health.

Having a similar question one should consult the pediatrician if in 11-13 months, the baby does not have any teeth. Then it can really testify a developmental disorder provoked by common diseases and pathologies.

Pediatrician considering the results of examining is able to detect any deviations and to start a specific treatment or assign a mineral and vitamin complexes.

Typically, in each case, all of the terms are completely normal, as explained by individual factors complex.

When can we start to clean baby’s teeth

Oral hygiene must be observed in any case throughout life. Therefore, even for very small children, there are some rules that should be followed.

Firstly, it should be before the first teeth regularly to clean gums. This can be done while bathing. Toothpaste is not yet used, there is no need for special brushes.

You can just easily rub the gums with gauze wrapped around your finger. Thus, it is possible to remove most of the bacteria, which are always present in the mouth. They are not dangerous before teeth appear, and an enamel can be negatively affected.

Secondly, there is a need to do cleaning when the teeth have only started to erupt. For this, there are special children’s toothbrushes with a small head.

You need to select the one, which has a comfortable handle. A toothpaste is also necessary. It should contain fluoride. To clean both sides of each tooth you need to take a very small amount – a size of a grain of rice.

Third, cleaning should be conducted twice a day, as in adults. Brushing a tongue to remove bacteria from the surface is also recommended. Rinse mouth for your child, using a small syringe, simply putting the baby on the side.

When there are more teeth, some of them can stand side by side. Then you should take advantage of a floss (very carefully). However, many dentists do not consider this procedure obligatory for milk teeth.
