We all know taking care of our teeth is important if we want to have fresh breath and a beautiful smile.

But did you know dental care is also important for the health of our heart, our blood vessels and our brain?

The latest medical research suggests that since the mouth is the gateway to the body, if our teeth and gums haven’t been looked after, it could cause harm to our other organs as we age.

Scientists believe this link could be because unhealthy teeth and gums tend to harbour bacteria, and this bacteria could leak into our bloodstream, increasing our risk of heart disease, stroke and even dementia* as we get older.

Luckily, we can lower the risk of developing serious illnesses as well as painful cavities (and yucky bad breath) by making sure we brush twice a day and floss or use interdental brushes*.

We should also do these six things to strengthen our teeth and gums and improve our oral health.

EAT LOTS OF OMEGA-3 FATS
The omega-3* found in fatty fish is excellent for general and oral health because of its powerful anti-inflammatory* effects, which means it brings down or reduces swelling. You can find omega-3 in salmon, sardines and mackerel.

“Some studies show that when people with gum disease* take omega-3s alongside dental treatment, their gums heal a little better,” said Dr Saroash Shahid, a reader in dental anatomy at Queen Mary University of London.

“Other good sources of omega-3 fats are flaxseed and walnuts,” Dr Shahid said.

EAT BEETROOT AND LEAFY GREENS
Not all bacteria in the mouth is bad. Some good oral bacteria are known to play a key role in turning nitrate* to nitric oxide*, which has been shown in numerous studies to relax and widen blood vessels and improve blood flow around the body, including to the brain. Joint research by University of Exeter health and life sciences professor Dr Anni Vanhatalo and dementia research professor Dr Anne Corbett has shown that eating plenty of nitrate-rich foods, including beetroot, can help with that process.

Leafy greens such as spinach, rocket and other salad leaves are also good sources of nitrate.

EXERCISE DAILY
Being active is good for your mouth, as a recent review in the Journal of Family Medicine and Primary Care found. Dental researchers looked at the effects of regular intense physical exercise – running, cycling, swimming and competitive sports – and found that those who are fit “have lower levels of inflammatory biological markers*, which is linked to better oral health”.

They also revealed that regular exercise helped the body’s production of salivary antigens*, substances in saliva that can trigger a positive immune response, helping you to fight off disease.

“Exercise improves blood flow, lowers levels of inflammation in the body that exacerbate* gum disease, and helps control conditions like diabetes and high blood pressure that can make gum problems worse,” Dr Shahid says. “While a workout in the gym won’t clean your teeth, staying active supports the gums and tissues that keep them in place.”

A diet high in fibre is good for your gut and your teeth.

EAT LOTS OF FIBRE
Foods high in fibre* are good for the gut – but they are also good for the teeth and gums.

A review by dental experts from Australia, New Zealand and India found that people who consumed 22-30g of fibre daily had less swelling of the gums, less plaque build-up and stronger tissues surrounding the teeth.

Crunchy foods like celery, raw carrots and capsicum promote oral health not just because of the immune enhancing antioxidants* they contain, but because they actually scrub the teeth as you chew them. Think of them as nature’s own interdental brushes, said Dr Neil Sikka, the director of dentistry at Bupa Dental Care.

“All high-fibre foods act a bit like a natural cleanser as they rub against your teeth when you chew,” he said. “The chewing they require stimulates saliva production, which, in conjunction with good brushing and flossing habits, helps to remove plaque from the teeth.”

EAT CHEESE AFTER A MEAL
Cheese is good news for your oral health. “It is not only rich in calcium and phosphorus*, which strengthen your tooth enamel, but cheese also helps to neutralise acid levels in the mouth,” Dr Sikka said.

Eating a small piece of cheese after eating acidic foods or drinks such as ultra-processed foods and fizzy drinks can help to raise pH levels in the mouth, reducing levels of bacteria that, over the long term, can lead to decay.

SEE YOUR DENTIST REGULARLY
It’s important to visit your dentist regularly so they can keep an eye on how your teeth and gums are going. They will be able to check for any signs of cavities or plaque build up while giving your teeth a good clean, polish and fluoride treatment to strengthen them as you grow.

It is recommended that you visit your dentist every six to 12 months for a check up or sooner if you have a tooth ache or notice a problem.

Regular dental check ups are important to prevent against cavities forming.

  • nitric oxide: a gas molecule that helps to relax blood vessels so that blood flows better and oxygen and other nutrients can be delivered to all the organs
  • inflammatory biological markers: substances that show how much inflammation there is in the body
  • salivary antigens: molecules found in saliva that helps the body produce antibodies to fight off bacteria and other pathogens
  • exacerbate: make something worse
