Chalk teeth in children – symptoms, causes and treatment

What are chalk teeth (also known as MIH) and what can be done about them?

Chalky teeth present a new challenge for many parents and dentists. Molar-incisor hypomineralization (MIH) describes the insufficient mineralization of the molars and incisors. According to current figures, over 30 percent of 12-year-olds are affected by this dental condition.

Chalk Teeth Symptoms: What exactly are chalk teeth?

Unlike healthy permanent teeth, chalky teeth are not fully mineralized. Normally, tooth enamel consists of approximately 97 percent hydroxyapatite, a calcium-containing compound. This compound is formed while the teeth are not yet visible. Various proteins ensure that the enamel receives enough calcium and that hydroxyapatite crystals are correctly arranged. In healthy teeth, proteins remain on the enamel when the teeth erupt and are removed through chewing – a normal process.

  • Chalk teeth in children
    The incisors and molars in the permanent dentition are frequently affected, which is why the condition is called molar-incisor hypomineralization. However, baby teeth are increasingly affected as well. In principle, all teeth in children can erupt as chalk teeth: incisors, canines, and molars.

With chalk teeth, the proteins do not function properly during tooth formation. The hydroxyapatite crystals are defective and too many proteins remain between the crystals. These dental defects are often visible when the teeth erupt. The enamel is unstable and crumbles when chewing, which leads to pain and frequently also to cavities, as painful teeth are usually not brushed sufficiently.

Research into the causes of chalk teeth: Plasticizers, infections & environmental toxins as possible causes

Researchers and dentists are continuing to investigate the exact cause of chalky teeth in children. Plasticizers in plastic are frequently cited as a cause of chalky teeth. There are many different types of plasticizers. Scientific studies indicate that bisphenol A in particular can be considered as a cause of chalky teeth. However, infectious diseases, upper respiratory tract infections, and medications such as antibiotics are also being considered. Environmental toxins are not ruled out as a cause of chalky teeth either.

Prevention of Chalk Teeth: Early MIH detection & treatment is crucial

Specifically preventing chalky teeth is very difficult at the moment. As long as the cause of chalky teeth in children has not been identified, no targeted preventive measures can be recommended. The earlier MIH is detected and treated, the better.

  • A preventive appointment with the dentist should take place as soon as the baby teeth are complete (at two to three years of age).

  • Through regular check-up and follow-up examinations, the progression of the damage and the extent of the chalky teeth are continuously monitored

  • With an early diagnosis, the dentist can treat progressive loss of tooth substance in chalky teeth in a timely manner and take any further necessary measures.

Treatment Chalk Teeth: Replenishing the calcium deficit with KAREX Tooth Protection Gel

Chalk teeth have incompletely formed tooth enamel. Our healthy tooth enamel normally consists of approximately 97% hydroxyapatite. One of the main components of hydroxyapatite is calcium.

With KAREX Tooth Protection Gel, pain sensitivity can be reduced, making life with chalky teeth more comfortable. It contains valuable calcium, xylitol, and high-dose hydroxyapatite (BioHAP). Regular use replenishes the calcium deficit and additionally forms a protective layer of hydroxyapatite on the teeth.

This additional remineralization also protects the chalky teeth against cavities and noticeably reduces sensitivity and pain.
