Polyunsaturated fatty acids, risk of tooth loss among older population

The dietary intake of certain polyunsaturated fatty acids could help manage the risk of tooth loss in older adults.

In a study published in Gerodontology, researchers asked more than 1,500 participants to self-report their consumption of n-6 and n-3 polyunsaturated fatty acids through a survey conducted at baseline and after a period of five years.

The researchers found that a higher intake of n-3 polyunsaturated fatty acids and a lower n-6:n-3 polyunsaturated fatty acid ratio was associated with fewer teeth lost; whereas a higher intake of n-6 polyunsaturated fatty acids was linked to greater tooth loss. Further, the participants who were younger, used dental floss more regularly and had adequate chewing ability were found to have better dental outcomes.

The researchers suggested that older individuals should consume greater amounts of n-3 polyunsaturated fatty acids to protect their dental health.
