Genetics play a role in tooth decay, gum diseases: study

If you notice your teeth decay more than it does for others, despite taking good care your teeth, you can blame the jeans. A recent study proved this theory to be true. According to the study, obesity, education, personality, and hereditary trains play a role in tooth decay and gum disease.
Two people who eat the same things and take care of their mouth the same way may end up with a different number of cavities but researchers have not been able to explain why until now, they said.

"The study makes it clear that teeth are part of the body. Among other things, we can see that there seems to be a causal link between risk factors for cardiovascular disease and tooth decay," said Ingegerd Johansson, from the Institute of Odontology at Umea University, Sweden.

The analysis involved scanning millions of strategic points in the genome to find genes with links to dental diseases.

The researchers were able to identify 47 new genes with connections to tooth decay.

"In the future, studies like this may pave the way to identifying people who are at particular risk of dental problems," said Simon Haworth, from Bristol Population Health Science Institute.

"However, no matter what genes people carry, good oral hygiene and diet are the most important things people can do to reduce the risk of tooth decay and gum disease," Haworth said.
