Lifestyle tips for healthy teeth

Taking care of your general health and your mouth is the key to making the most of your smile.

Brushing your teeth twice a day (last thing at night before you go to bed and on one other occasion) with fluoride toothpaste and having regular check-ups with a dentist can help keep your teeth healthy. Diet, smoking and drinking alcohol also have an effect on dental health.

A healthy diet is good for your teeth

What you eat and drink can cause tooth decay, so a healthy diet is important for your teeth.

A healthy, balanced diet includes plenty of fruit and vegetables, as well as starchy foods such as bread, rice, potatoes and pasta (choose wholegrain versions and eat potatoes with their skin where possible).

You should also eat sources of protein such as meat, fish, eggs, beans or other non-dairy sources of protein, and some milk and dairy foods (ideally lower fat options).

Only eat small amounts of food and drinks high in fat and sugar. The eatwell plate shows how the different types of food should make up your diet.

Reduce sugar to prevent tooth decay

Limiting the amount of sugar you eat and drink is important to prevent tooth decay.

A lot of the sugars we eat and drink are in food and drinks such as:

  • sweets, chocolate, cakes and biscuits
  • sugary drinks, including soft drinks, fizzy drinks, milky drinks with added sugar, and alcohol
  • fruit juice, including fresh fruit juice
  • buns, pastries and fruit pies
  • sponge puddings and other puddings
  • table sugar added to food or drinks, such as tea
  • sugary breakfast cereals
  • jams, marmalades, honey and syrups
  • ice cream and sorbets
  • dried fruit or fruit in syrup
  • syrups and sweet sauces

Try to cut down on the added sugar you have in your diet.

Stick to one glass of fruit juice a day

Sugars occur naturally in foods such as fruit and milk, but we don't need to cut down on these types of sugars.

But when fruit is juiced or blended, as in smoothies, the sugars are released from the structure of the fruit. Once released, these sugars can damage teeth, especially if you drink fruit juice frequently.

Even unsweetended fruit juice is sugary, so try not to drink more than one glass (about 150ml) of fruit juice each day.

How smoking damages teeth

Smoking can stain your teeth yellow, cause bad breath, and increases your risk of gum disease, breathing problems, lung cancer and mouth cancer.

If you smoke 20 or more cigarettes a day, you're six times more likely to develop mouth cancer than someone who doesn't smoke. So giving up smoking is important if you want to look and feel better.

Alcohol and oral health

Alcohol misuse has been linked to an increased risk of developing mouth cancer. According to Cancer Research UK, 75-80% of mouth cancer patients say they frequently drink alcohol.

The most important risk factors for mouth cancers are the combined effect of smoking and drinking alcohol.

It's estimated that heavy drinkers and smokers have a 38 times increased risk of developing mouth cancer than people who neither drink nor smoke.

Alcohol can also erode the outer surface of the teeth, leading to a loss of enamel. If this happens, you may need to go to the dentist for a filling.

Eat right for a whiter smile

Some substances, foods and drinks can stain your teeth. Wine, cigarette smoke, tea and coffee are all teeth-staining culprits. Keep them to a minimum to stop your teeth becoming stained.

Your dentist or hygienist will be able to give your teeth a professional clean, which may help reduce the staining. 

If you want to find out about other options, such as tooth whitening, have a chat with your dentist.

Great reminders for everyone as sometimes these simple lifestyle tips may be forgotten. We work with a lot of dentists on a daily basis, and one good tip is also to drink a glass of water after every meal. Water is vital for great oral health, acts as a natural cleaner and has the power to wash away bacteria and residue left on the teeth after eating.
