According to scientists in Australia, gum disease can prolong a woman's likelihood of conceiving by an average of two months. Further research has also revealed links between gum disease and premature birth and miscarriage.
A study of nearly 4,000 pregnant women carried out at Guy's and St Thomas' Hospital in London found those with poor oral hygiene had a greater chance of having a late miscarriage.
Moreover, gum disease has been associated with bone diseases such as arthritis.
Dr Paola De Pablo, a rheumatologist at the University of Birmingham, told the Daily Mail that gum disease and the link to rheumatoid arthritis is a subject that has received more media attention in recent years.
"We believe what happens is that the bacteria from the gums secrete proteins and these proteins prompt a response from the immune system which kick-starts the arthritis," he added.
According to toothpaste company Colgate, brushing the teeth twice a day with fluoride is a key part of maintaining optimal oral hygiene.
