Teeth enamel in children and ADHD: is there a connection

The state of the oral cavity can be considered as an indicator of general health – symptoms are simultaneously predisposing factors for the development of diseases. Until recently, the state of the teeth of children and adults was not given sufficient attention as a diagnostic factor. Recent studies have shown that in children with thinner enamel and anomalies of its development, attention deficit hyperactivity disorder (ADHD) is most often recorded. When parents need to pick up the phone and make an appointment with a doctor, and what data were obtained during the research .

Attention Deficit Hyperactivity Disorder

According to some reports, ADHD is one of the most common child health problems. Such a diagnosis is made in Russia by 4-18% of children ( Zavadenko N.N.), in the USA – 11-20%, the lowest prevalence in the UK – 1-3%.


Adults who also suffer from symptoms can also be diagnosed. Moreover, representatives of the stronger sex are more often affected.

As a rule, the diagnosis is made to older children. Diagnostic criteria can be considered:

  • the child is unable to concentrate;
  • constantly makes impulsive decisions;
  • hyperactivity.

In clinical practice, it is customary to distinguish 3 types of ADHD, which are characterized by different symptoms, therefore, there are peculiarities in the treatment:

  • Combined type

It is considered the most common type of ADHD. It is characterized by: impulsive and hyperactive behavior, difficulty concentrating.

  • Predominantly impulsive

The least common type, when children or adults are hyperactive, there is a need to constantly move, impulsive behavior is characteristic. At the same time, there are no violations of concentration or inattention.  

  • Mostly inattention

There are no signs of hyperactivity or impulsivity. Disturbance in concentration is characteristic.

What are the causes of ADHD?

The exact causes of ADHD are not yet clear, there are only theories and assumptions. It is noticed that heredity matters: if one of the parents or siblings has a disorder, the child born is likely to develop the syndrome.

Recently, scientific work has focused on identifying risk factors, as well as the causes of the development of the syndrome. Factors that potentially increase your risk of ADHD include:

  • Influence on the course of pregnancy

If the mother suffered from chronic stress during pregnancy , severe emotional disorders, as well as bad habits: alcohol, tobacco smoking, drugs.  

  • Influence of the environment

Exposure to environmental toxins during pregnancy or from a very young age can also be considered a risk factor. Accommodation in an industrial area, air pollution, etc. are important.

  • Low birth weight

A 2018 study found a link between low birth weight and the development of the syndrome. This can be explained by the fact that low body weight, as well as premature birth, are associated with difficulties in the development of the nervous system.

  • Traumatic brain injury

Even minor trauma can cause the syndrome to develop.


There are still many persistent rumors circulating around ADHD that do not correspond to the truth. Contrary to popular belief, the following factors do not lead to ADHD:

  • uncontrolled consumption of sugars or artificial colors;
  • abuse of watching TV, computer games, as well as the phone;
  • upbringing mistakes and unfavorable home environment.

Studies have not found an association between these risk factors.
