Your oral health might not be the first thing that comes to mind when you think about stroke prevention, but it plays a bigger role than you might realise.

The link between oral health and strokes

Research shows that poor oral health can negatively affect your body and increase the likelihood of cardiovascular diseases (CVDs), which typically affect your heart and blood vessels all over the body. Strokes are part of this because they happen when blood flow to your brain is blocked or reduced.

Bacteria in your mouth can enter your bloodstream, often through areas affected by gum disease caused by plaque – a sticky, soft substance that forms on your teeth. Once in your bloodstream, these bacteria can contribute to inflammation and the hardening of arteries. This can increase the risk of strokes and other serious medical conditions.
