Brushing your teeth regularly may reduce your risk of throat cancer, according to a study from New York University.
The findings, published in the journal Cancer Research, were based on mouth samples taken from 122,000 participants. During the ten years of follow-up, 106 participants developed oesophageal cancer.
The researchers analysed the bacteria in the samples and identified two types linked to a higher throat cancer risk.
Previous research has shown that periodontal disease caused by some bacteria has been associated with several types of cancer.
The researchers say their study confirms that good oral health, including regular brushing, is a key way to prevent cancer.
