The address determines if your child gets cavities in the teeth

Most parents think that their residence may have an impact on whether their children will get tooth decay or not. A new Danish study shows that there is a strong correlation between the children's and young people's place of residence and the risk of caries (holes in teeth), writes Tandlægebladet.

Fluorkoncentrationen in the tap water that comes out of the taps in the home, can have a crucial impact on their children's cariesrisiko. Children who live in Siberia, are twice as likely to get tooth decay as children living in the southeastern part of Zealand and on Lolland-Falster, Møn and Bornholm, where fluorkoncentrationen is the highest.

There is a big difference in fluorkoncentrationen in the drinking water, depending on where you are in the country. If one lives as a child or young person in an area where there is a high concentration of fluoride in the drinking water, it may mean that the risk of getting cavities in the teeth can be half as great as in an area where fluorindholdet is low – for example in west Jutland, where the risk of getting holes in your teeth is up to twice as large as the areas where fluorkoncentrationen is a maximum. The more fluoride in the water, the fewer holes.
The survey is conducted among 48.351 children 5-years of age and 43.848 15-year-olds in the entire country.

”Sweet” cultural background affects children cariesrisiko

If the mother and father have a short education or non-western background, the risk of caries in children is significantly larger than that of the average. It shows a new Norwegian study, published in Community Dentistry and Oral Epidemiology.

In the survey received 523 children made tandundersøgelse, while the parents responding to questions about the socio-economic conditions and on own tandplejevaner. In the group of parents with non-western background and education had the children, respectively, nine and twelve times more at risk for incipient caries in the enamel and tandbenet. This is due to excessive sugar intake, and lacked regular brushing.

Non-western background and education
“In the group of parents with non-western background and education had the children, respectively, nine and 12 times as likely to have incipient caries in enamel and in dentin. However, the confidence intervals for these probabilities was quite large, ie. uncertain and one should also notice that it is about 24 children out of a total of 523”, says Dorthe Holst, professor of samfundsodontologi at Oslo University, and adds:

"There is much to indicate that there is a "sweet", and not too systematic tandbørstekultur behind the numbers. Småbørnskulturen in part non-western families is different than it, which gradually came to characterize most of the nordic. We also find high cariesaktivitet among Norwegian children, but it is rather a windows - than a kulturudfordring. Fortunately, studies of the same issue, among 14-16-year-old children and young people in Oslo, have shown that the differences are blurred. A good and respectful communication with current families at risk should be able to give good results”.

No-shows giving rise to the risk of caries in children

No-shows increases the risk of caries in children

No-shows from tandlægeaftaler, dental phobia, as well as parents who are avoiding dental treatment, are risk factors for the development of caries in children, shows a new Swedish study. The survey includes more than 500 children and their parents.

The Swedish authors conclude that children, who have a history of no-shows, and who have parents who fail when it comes to complying with the children's tandlægeaftaler – they have an elevated risk of having developed dental caries as a five-year-old.

Tooth decay is transmitted from adults to children

It is probably very few new mothers, who know bakteriesammensætningen in their own saliva and probably even fewer that know this have an impact on their child's dental health the rest of his life. Kisses and hugs are fine, but contact and exchange of saliva can transfer the ”cariesbakterier” from mother to child. Parents should be better informed, reads the assessment from the Professor of Dentistry in Copenhagen Svante Twetman.

Mothers pass bacteria to their children
People who have much caries, and often have a special bakteriesammensætning. And these ”cariesbakterier” can infection. Studies show that the bacteria in infants in more than 70 percent of the cases comes from the mother, however the infection can also take place from other relatives or, for instance, in vuggestuemiljøet.

Mom with many ”cariesbakterier” are at high risk to transfer these to their children by, for example, to share the fate of their children or the taste of the baby feeding bottle. The earlier a child is exposed to the cariesbakterier, the greater the risk is that the bacteria establish a permanent and on a large scale. Thus, there is increased risk that the child develops caries in pre-school, writing Tandlægebladet.

According to professor Svante Twetman is it first and foremost to avoid direct spytkontakt. You should as parents avoid to take the child's pacifier or other things that need to check in the child's mouth, into his own mouth. One should not, for example, test barnemadens temperature in his own mouth. And one should not wash the pacifier or ”do it clean” by taking it in the mouth.

Another precaution, which the mother can take is to try to reduce its own level of cariesbakterier. With a background in several independent studies highlights Svante Twetman, ”mother can treat themselves antibacterial by rinsing the mouth with klorhexidinopløsning, or she may choose to chew xylitoltyggegummi in the period up to the child's first tandfrembrud.”

He stresses that there is some evidence that the tandsundheden in children can be improved if the tandplejepersonalet provides prospective and new parents information and advice on how to avoid the transfer of cariesbakterier to her child.

Professor advises against the recommendation of sugarless gum

14. may 2009  
Filed in News

The EU experts have recognized chewing gum with xylitol as a preventive against dental caries. But now, warns a professor of dentistry in Copenhagen against overfortolke the message that sugar-free gum with xylitol reduces risk of tooth decay in children.

A group of experts from the The European Food Safety Authority has determined that the xylitoltyggegummi reduces the risk of cariesudvikling in children. And thus, there should be scientific evidence to say that sugar-free chewing gum containing polyols (xylitol and sorbitol), decreases the risk of having gaps in the teeth.

But now warns professor Svante Twetman from the Dentistry in Copenhagen, as Tandlægebladet have asked, against an over-interpretation of the message that sugar-free gum with xylitol reduces risk of tooth decay in children, and the professor does not think that we should recommend to the Danish children to chew gum to avoid cavities in the teeth.

Industrial interests and insufficient documentation
Svante Twetman points out that the EU experts ' conclusion is based on the reports, which in many cases is initiated on the basis of industrial interests. And that the studies that underlie this conclusion are of highly varying quality, scientifically speaking. Bl.a. is previous work and field studies from Latin america included, and it is the study, which, according to Twetman lacks validity for Danish conditions.

Professor Svante Twetman believe, therefore, that the documentation for xylitols preventive effect in relation to the holes in the teeth is insufficient. And he misses in addition, a health economic evaluation of chewing gum against the holes. A careful calculation shows that the prevention of just a single hole will require 4.000 – 5.000 pieces of chewing gum. And since the risk of cavities in the teeth in Danish children is already very low, there is not a need to mitigate this risk with xylitoltilskud.

No recommendations with lack of knowledge
Svante Twetman will not, however, exclude the possibility that sugar-free chewing gum with xylitol and sorbitol can have a beneficial effect on tandsundheden. It stimulates the spytudviklingen, and it can not be excluded that xylitol and sorbitol can affect the oral environment in a positive direction.

Svante Twetman suggest it as a possible complement to the treatment, one usually uses in order to stop the development of a hole in a tooth in children and young people with a high risk of tooth decay, for example fluorbehandling and varnishing. But he emphasizes at the same time, that as long as there are gaps in our knowledge of e.g. optimal dosage, there may not be a general recommendation of chewing gum with xylitol and sorbitol.

Can the state/municipality to cover my tandlægeregning?


Since I have many sølvfyldninger and just for 5 min.ago has cracked yet another tooth I could like to hear about the dentist know about the state/municipality will cover my tandlægeregnig when I am about to be tired of that should have changed the teeth out with someone in the plastic.Have not had a gap in my teeth since I left primary school for a number of years ago and at the time only go to the dentist without having holes and be drilled and have filled the silver in my teeth.Have a hard time believing I can be the only one with this problem.This is just a polite inquiry.



Dear Susanne

I can well understand why you are frustrated. But the teeth wear out too with age, and it is quite normal that they break with time, especially when they have been drilled in before. The cause may be dental caries or infraktion in the tooth.

You can seek local authority about grants for dental care. So you must together with your dentist create a treatment plan that says what treatments are necessary and how much they cost. This must be included when you apply for grants. It is individually where/ or if we get some money for treatment, and this is taken into account what income you have.

Hope you can use my answer.

With kind regards

Tandsundheden among Greenlandic children alarming

22. april 2009  
Filed in News

Tandsundheden among Greenlandic children and young people is so poor that small children down to one year of age will get pulled mælketænderne out.

“We must often remove the bad baby teeth because of advanced caries in young children,” says dentist Jørgen Ramstedt Jensen in Tasiilaq.

“If you do not take care of your teeth, you can get inflammation, and it goes not only the teeth but also the rest of the body gets affected,” says dental assistant Johanne Hansen to the CNTS.

A few years ago was the regular tandskylning with fluoride stopped in Tasiilaq, and children and young people have not been given regular dental examination or instruction in toothbrushing.
Tasiilaq rates now on, to be able to offer all primary school children regular dental examination and instruction in tooth brushing. And restores now the regular fluoride-rinses in children.

Nationwide cariesstrategi
The Greenland home rule government launched in 2006 a national strategic plan against caries called Cariesstrategi Greenland 2008 – 2012as part of the The Public Health Programme Inuuneritta. The strategic plan aimed, among other things, to step up efforts for the prevention of dental caries, and it should be mandatory by 1. January 2008, with the systematic tandplejetilbud to the population, or at least a systematic tandplejetilbud for children and young people, where there may not be sufficient capacity or economy to the entire population.

The National Tandbørstedag
As a direct cause of the poor dental health of the population of greenland, the Greenland home rule the 18. april 2007, as the first country in the world, a national tandbørstedag. The National Tandbørstedag in Greenland is 18. april.
