Acid injuries especially prevalent among teenage boys

Every third 16-year-old boy in the city of Frederiksberg has acid injuries of the teeth, which means the etching of the tooth enamel. Cola, soda and other soft drinks are supposed to be the main reason for syreskaderne – in the specialised language called erosions. The result comes from a study carried out by Frederiksberg Municipality's Dentistry, and, as presented in the Tandlægebladet.

In general, have more than one seventh of the 12-to 17-year-olds in the city of Frederiksberg acid injuries to the teeth. The problem is most often seen among boys, and the damage gets worse, the older you get.

In Tandlægebladet presents overtandlæge Lene Esmark from Frederiksberg and the Municipality of Dentistry the results of a survey of the scope and severity of erosions among 2.151 of the municipality's children and young people in the 12-17 years of age.

According to the survey, 313 of the young people, equivalent to 14.6 per cent. at least one tooth with acid injuries. Five have so severe damage to large areas at minimum one tooth is completely without enamel.

In all age groups is the prevalence of acid injuries highest among the boys, especially in the 15-to 16-years of age. Among the 16-year-olds, for example, has at 7.6 per cent. of the girls, acid injuries, while the same is true for the whole of 32,8 per cent. of the boys. The big gender difference is offset a bit after 16-years of age, but the problem is still most prevalent among the boys. The five persons with the most serious type of erosions are also all boys.

In general, it can be seen that the problem with acid injuries increases with age. The older the adolescents become, the more frequent is the occurrence of acid injuries, as the severity of the damage also increases.

Frederiksberg Municipality's Dental care will now continue to develop targeted prevention programmes in the form of guidance and enlightenment. Efforts must be directed particularly against the boys and should already be implemented from the age of 12 years.

Water with lemon juice etches the teeth

Cola, fruit Juices and smoothies are far from the only drinks you should be careful with, if you want to avoid acid injuries to the teeth. Water with lemon or limeskiver is almost just as bad for the teeth such as cola.

Summer, sun and cold drinks
Now summer is approaching rapidly, increasing the need for cold drinks to make the thirst with along with the temperature. In cafes and restaurants is ice-cold tap water with fresh lemon or limeskiver become very popular among the young people, as a “healthy” alternative to the often sukkerfyldte soft drinks, which can also be very acidic.

But you drink citronvand more than once per day, you risk the enamel on your teeth corrode and after a single summer's consumption, you can look forward to a hefty bill from the dentist in several thousands of dollars, writes Urban. One of the country's leading researchers in the field of dental disease, overtandlæge Ulla Pallesen call tanderosion for a regular epidemic.

The etching of the teeth
“It damages the teeth in nearly the same degree as the cola. The more sliced lemon, in a pitcher of water, the more the enamel is etched there. There is no doubt that the pH-value smoking significantly less than the 5.5, which our teeth can withstand,” says Ulla Pallesen, who daily works with and teaches in the dental diseases at Copenhagen University, for Urban. “The enamel is etched slowly, but surely, even if no one marks or can see in the beginning,” explains overtandlæge Ulla Pallesen on.

Her research shows that the etching of the teeth is a major problem among young people under 30 years of age. And she estimates that the frequency of the disorder is second only to dental caries and periodontal disease. The first and only study on the number of acid injuries among teenagers was made in 2001 in the municipality of Aarhus in cooperation with The Municipal Dentistry in Aarhus. This study showed that every sixth between 15 and 17 years old had severe acid injuries to the teeth.

How can one protect themselves from acid injuries
You can't keep from citronvand, and other acidic beverages, you should limit intake to a maximum of once per day. The worst thing you can do is to drink it frequently and at regular intervals through the day, as it takes time for the mouth and the teeth the pH value to stabilise again. The consequence of the frequent acid bath in of the teeth comes creeping, and you can't completely brush-free for them. Indeed, one should avoid to brush the teeth right after consuming acidic drinks, and instead of rinsing the mouth with clean water immediately after use. Acidic beverages should not be consumed with small sips over a long time, but should instead be enjoyed quickly or with a straw.

You should also be aware that the excessive eating of sour fruits – such as lemons and oranges, as well as chewing of sour candy – as f.ex. wine gums – can dissolve the enamel and allow acid injuries.
