Cancer and teeth aren't typically linked in conversation, but a Harvard study showed one bad habit while brushing your teeth could increase the risk of two different cancers.
It's not always clear why cancer cells begin growing, but there are general health habits to help reduce your risk.
You probably know that stopping smoking and eating healthy are two major ways, but probably less so when it comes to gum health and brushing your teeth.
A study from Harvard revealed one common mistake related to your toothbrushing habits that could increase your risk, The Mirror reported.
Bad oral hygiene can lead to two different cancers, according to the research.
Here's what you need to know about teeth and cancer.
How does your brushing habit increase risk of cancer?
The Harvard study published in the journal Gut late last year has found that gum disease could lead to a significantly higher risk of two cancers.
Scientists found that microbes camping out between your teeth and gums may affect your risk for cancers of the stomach and oesophagus.
The research included almost 150,000 men and women, who were given a follow-up after a gap of 28 years.
It revealed that people with a history of gum disease are 43 percent more likely to develop oesophageal cancer and 52 percent more likely to develop gastric (stomach) cancer than those whose gums are healthier.
Risk was found to be even higher among those with gum disease severe enough to cause tooth loss.
While the study doesn't prove that gum disease causes cancer, it does mean that in future doctors might be able to look at your gum health when assessing your overall cancer risk.
What are the symptoms of gum disease?
Gum disease is a very common condition in which gums become swollen, sore or infected.
It can be caused by a number of factors, but usually a build-up of plaque on your teeth due to lack of brushing is a primary cause.
The first signs of gum disease according to the NHS are:
- Red and swollen gums
- Bleeding gums after brushing or flossing your teeth
This initial stage is called gingivitis, which if left untreated can affect the tissues and bone that support the teeth as well, becoming periodontitis.
Symptoms of periodontitis are:
-
Bad breath (halitosis)
-
An unpleasant taste in your mouth
-
Loose teeth that can make eating difficult
-
Collections of pus that develop under your gums or teeth (gum abscesses)
How to prevent gum disease
In most cases, it's easy to prevent gum disease by improving your oral hygiene. The American Dental Association recommends that you brush your teeth twice a day, floss at least once a day, and get a dental exam and cleaning regularly.
Sometimes you may need further treatment such as periodontal surgery if your gum disease is more severe.
The NHS explained: "Your dentist will be able to tell you about the procedure needed and how it's carried out. If necessary, they can refer you to a specialist."
