According to a new research, expecting mums suffering from gum disease are more likely to have preterm infants.

Scientists discovered females with gum problem were over three times more likely to give birth ahead of time as compared to mums-to-be with good oral health.

They also experienced a one in four chance of having delivery before 35 weeks.

Over 1,000 pregnant women between six and 20 weeks maternity were followed for the research. The 160 partakers diagnosed with periodontal (gum) problem were compared to the 872 preggies who had good levels of oral health.

The study outcomes indicated that women who were treated for the condition with scaling and root planning were much less likely to have a premature birth at below 35 weeks.

Nigel Carter, chief executive of the British Dental Health Foundation, thinks that the research adds to the growing proof, whick links gum disease with premature babies.

Carter said, "It is further strong evidence that pregnant women should take care of their teeth and receive appropriate treatment during their pregnancy to reduce as far as possible their chance of a pre-term birth."

"Due to hormone changes during pregnancy, some women's dental health needs closer attention during this time. For instance, you may notice that your gums appear to bleed more easily. This means that you must keep a high standard of oral hygiene, visiting your dentist regularly. This may include appointments with the dental hygienist for thorough cleaning, and advice on caring for your teeth at home," Carter added.

The study was publicized at the Annual Meeting of the American Association for Dental Research in Washington. (With Input from Agencies)
