Fillings may do more harm than good, senior dentists have warned, as they called on ­colleagues to ensure they use up-to-date techniques.

Done badly, fillings can ­increase decay, and mean more are needed in other teeth, ­dentists said. Experts believe the trauma caused by the ­initial filling may explain why ­neighbouring teeth become prone to infection.

The research, published in the 'Journal of Dentistry', showed some dentists are more likely than others to have ­patients who develop new decay after a filling. Health ­professionals said it suggested that the techniques being used were a key factor.

Prof Damien Walmsley, spokesman for the British Dental Association, said: "This study highlights the fact that dental intervention can cause more harm than good. More research is urgently needed to find out why dentists could be causing these problems."

The study found six out of 10 teeth which were next to a filling had also decayed after five years. Almost 30pc of these needed filling.

Prof Walmsley, a leading dental expert at Birmingham University, said: "Once a dentist has gone into a tooth, they may accidentally damage ­another tooth. Dentists need to keep up-to-date with the latest ­techniques to ensure they don't damage other teeth when they do a filling."

The experts stressed that patients should have fillings, as there is no other solution when teeth are badly decayed. But they said dentists must be careful with their approach, using "minimal intervention" to reduce the chance of ­damaging teeth. They also said patients ­needed to be particularly ­careful about taking care of their teeth after a filling, by reducing sugar intake and ­ensuring they brushed properly.

Simen Kopperud, of the ­Nordic Institute of Dental ­Materials in Oslo, Norway, who led the study, said: "It is highly possible that the intervention by the dentist causes a problem in adjacent teeth. Fillings are not an ideal solution but at the moment it's the best solution we have."

Dr Kopperud said dentists "need to be aware of the risks" and consider greater use of new treatments. He also urged patients to be vigilant about oral hygiene once they have had a filling. The risk of decay is higher in patients who eat sugary snacks and drinks or do not brush teeth properly.
