On milk teeth the world was still fine for many children – but suddenly none at all with the remaining bitters. ugly discoloration, Furrows, a rough surface, plus the sensitivity to pain that makes every brush torture. chalk teeth The phenomenon is called, experts speak of molar incision hypomineralization (MIH). The problem with this is that no one really knows where the disease is coming from – and therefore how it can be prevented. At the same time, the number of patients is increasing: 28.7 percent of twelve-year-olds have it chalk teeth that is, MIH – a disease that was first diagnosed in 1987. This is the result of the fifth German Oral Health Study (DMS V) of 2016.
How new are they chalk teeth Really?
"You can already get that from one widespread disease speak, ”says prof. Stefan's room, President German Society for Preventive Dentistry (DGPZM). But even these numbers – or their interpretation – are claimed by experts: Are there really more cases chalk teeth? Or are they just more noticeable? The idea behind this: MIH is recognizable on the teeth only if they do not have caries, explains prof. Dietmar Oesterreich, Vice President of German Dental Association, And while the number chalk teeth The number of caries cases among children and adolescents has been declining strongly over the years. Some experts suspect that the disease has existed before – just unrecognized. Others are more cautious: "I think it's a new disease," he says room, "There were also caries-free teeth in the '80s, and incisors were often healthy in the past – and MIH is there."
Sunscreen or plastic: Who's to blame?
Similarly, the issue of the cause of the disease is controversial. Above all, experts agree that nothing is known exactly. "No clear cause-and-effect relationship has been found so far," he says Austria, "There is a lot of talk about environmental impacts – but if that's really the reason, you can only guess at the moment." "One has to think: what has changed so dramatically in terms of environmental conditions in our diet that can explain the huge number of MIH teeth," he explains Stefan's room, "It's not a local phenomenon, it's global."
Therefore, two phenomena have been called into question, he says room: First, vitamin D deficiency, caused by less sun exposure and much more sunblock, especially for toddlers. "Parents are extremely cautious today with the sun exposure of their children. Today, sunscreen has much higher sun protection factors."
Another popular explanation: plastic bottles. For those who drink from the 80s and 90s significantly more often than before, he explains room – at exactly the time when the first MIH cases were diagnosed. A possible trigger, for example, is bisphenol A (BPA), which is sometimes used in the manufacture of used bottles. Federal Bureau of Risk Assessment (BFR) finds this connection unlikely.
Formed early – but discovered late
Exploring the cause is further complicated by the fact that years often occur between the onset of the disease and its diagnosis. Because in most cases MIH comes first and only on permanent teeth. They were discovered chalk teeth And only when the affected biter fails. They were formed, that is, their enamel – and thus the disease – but much earlier, in the first years of life, namely. "If you see MIH, it's already happened," then room, The disease is difficult to prevent – but to cure. The first step in this: don't panic. Not everyone is discoloration is an indicator for chalk teeth.
"MIH usually occurs in children only on permanent front teeth and on the first permanent molars," he explains Austria, First molars are large permanent molars that usually break first. If there is a change in the color of the other tooth, MIH is not usually behind it. "And also on otherwise affected teeth, changes can have other causes."
Not everyone is chalk tooth it must be under the drill
Even if a tooth is actually diagnosed with MI, it is not worth the long treatment. Only about five percent of diseased 12-year-olds say the disease is so pronounced that they actually have to do something, he explains Austria, "The others really are discolorationbut does not necessarily follow the therapy – no dentist will pick up the exercise. "For a doctor, parents with discolored teeth need to go to safety, but they don't have to be a specialist." MIH is part of the training for dentists "There are numerous courses on this," he says Austria, "Today, every dentist is able to recognize and treat the disease."
MIH is especially worth the cure, if in addition discoloration a so-called melt break occurs. Because this increases the tooth's sensitivity to pain. The first contraption then usually diseased teeth with plastic for the charge and special use of fluoride, therefore Austria.
In rare cases, the tooth is also so damaged that it has to come out. In children and adolescents, this is usually still pretty good, explains the expert: "Today you also have the opportunity to treat orthodontic – so remove the teeth and close the gap created by orthodontic measures with other permanent teeth."
Observe – and consistently clean
It stays with discoloration, MIH is generally just an aesthetic problem – and it is something that is not treated in childhood and adolescence, he says Austria, Fluoride varnish can help your teeth regrow minerals. For all other measures, the risk is too great to damage the tooth.
Good oral hygiene is always important. And especially with MIH parents have to pay attention. Because otherwise, the safest discoloration worse, he explains room – partly because it is a rough surface chalk teeth makes it much more delicate: "Teeth are delicate; children do not want to brush them. Then a jerk is carelessly created."
