Worried about the dentist Painful trips could be a thing of the past thanks to new crowning technique for decayed teeth
Painful fillings could soon be nothing more than a bad memory.
Experts are trialling a pain-free way dealing with rotten teeth that dispenses with the dentist’s drill.
It is also done without the need for anaesthetic jabs and appears to be more effective than a conventional filling.
The results of pilot studies have been so promising that the NHS has pumped 3million into a nationwide study of the technique, which involves sealing decay in, rather than scraping it out.
Pain: A new technique for removing decay in teeth could help remove the fear of going to the dentist for millions of people
The bad news is that it is, for the moment at least, only suitable for milk teeth and so for children, rather than adults.
Normally, having a filling involves being given an injection of local anaesthetic. The rotten part of the tooth is then removed using the drill and the hole packed with filling.
Under the Hall technique, named after Aberdeenshire dentist Norna (CORR) Hall, no effort is made to remove the decayed part of the tooth.
Instead, a metal crown is simply slipped over the tooth and cemented in place.
No anaesthetic is needed and, starved of bacteria and oxygen, the decay stops or slows down to such a rate that it doesn’t cause any pain.
Bad news: The technique only works on milk teeth so will only benefit children initially. (File picture)
The crown stays in place until it falls out naturally with the tooth, at around the age of ten.
Innes, a lecturer in paediatric dentistry at Dundee University, has
carried out two studies into the ‘child-friendly’ technique.
She said: ‘The Hall Technique is now taught as a standard part of the undergraduate dental programme in almost all dental schools now.
‘Sealing in decay is getting a lot of interest but we know that although it has been investigated for more than 30 years and there is a strong body of evidence supporting it, many dentists still view decay as a gangrenous type of disease that needs to be cut out surgically.’
In a two-year trial of 132 children aged between three and ten, children, parents and dentists all preferred the Hall technique.
Teeth treated this way also caused fewer problems in the future.
For instance, just 2 per cent of teeth treated through the Hall technique went on to develop major problems such as abscesses or become do badly decayed that they were beyond repairing.
In the group giving fillings, the figure was 15 per cent.
A five-year trial produced similar ‘astonishing’ results.
NHS-funded trial will study almost 1,500 children treated at 50 dental
practices in the north of England, inner-city London and Scotland and
Institute for Health Research, the NHS’s research arm, said: ‘A
successful outcome for the study will be the ability to make a firm
recommendation regarding the most effective approach for managing decay
in children’s teeth.’
Professor Jimmy Steele, of the NIHR,
told the Sunday Times: ‘This is challenging what has been conventional
wisdom for 150 years.’
technique is, at the moment, only suitable for baby teeth. But a version
suited to long-lasting adult teeth is being worked on.
