Having advanced periodontitis triples the probability of suffering a future ischemic stroke



One of the groups of cardiovascular diseases with the highest mortality in our society. On this day, we seek to raise awareness of this frequent and severe disease and its link to periodontal health.

Every year they suffer a stroke, and 13% of them do not survive it, which makes this disease one of the most important causes of death.

Of the survivors, it is estimated that 30% are left with some kind of disability. The most common type of stroke is ischemic (corresponding to 80% of total cases of stroke), which is caused by a blockage of an artery in the brain, either by a clot that occurs within the brain's own blood vessel or by a clot that occurs elsewhere in the circulatory system and travels to the brain.

Oral Health Influence


It is currently known that cumulative exposure to certain oral bacteria, such as those involved in periodontitis, produces a chronic pro-inflammatory state not only at the gum level but also in the rest of the body, increasing the risk of stroke.

In fact, it is estimated that a person with advanced periodontitis is 3 times more likely to suffer a future ischemic stroke than a person with healthy gums. In addition, in patients who have already suffered an ischemic stroke, the risk of a second vascular event is 2 times higher in those with advanced periodontitis.

These data are even more significant if we consider that very few of the adult population are periodontally healthy, more than half suffer from gingivitis, and 38% on average have periodontitis, increasing to 65% in those over 55 years of age.
