Lifestyle tips for healthy teeth

Taking care of your general health as well as your teeth is the key to making the most of your smile.

Brushing your teeth twice a day with fluoride toothpaste, flossing them daily and having regular check-ups with a dentist can help keep your teeth healthy. But diet, smoking and drinking alcohol also have an effect on dental health.

A healthy diet

What you eat and drink can cause tooth decay, so a healthy diet is important for your teeth. A healthy diet contains foods from different groups, including fruit and vegetables, starchy foods (rice, pasta, bread and potatoes), some protein-rich food (such as fish, meat, eggs and lentils) and some dairy foods.

Find out more about how to eat a balanced diet.


Limiting the amount of sugar you eat and drink is important to prevent tooth decay. Have sugary food and drink only at mealtimes and don't eat sugary snacks between meals.

Most of the sugars we eat and drink are contained in processed and ready-made food and drinks. These include:

  • sweets, chocolate, cakes and biscuits
  • 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 and honey
  • ice cream
  • dried fruit or fruit in syrup
  • syrups and sweet sauces
  • sugary drinks, including soft drinks, fizzy drinks, milk drinks and alcoholic drinks
  • fruit juice

A glass of fruit juice counts towards your five portions of fruit and vegetables a day, but it also contains sugar. When you have sugary food or drink with a meal, it can be less damaging to your teeth than if you eat or drink it on its own. Try to drink fruit juice only at mealtimes.

Smokers' teeth

Smoking can prevent you from having gleaming, healthy teeth. Smoking turns your teeth yellow, causes bad breath and increases your risk of gum disease, breathing problems and lung 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 tooth decay

Excessive consumption of alcohol 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.

Alcohol can also erode the enamel on the outside of your teeth, leading to decay. If this happens, you may need to go to the dentist for a filling.

A whiter smile

If you want to keep your teeth as white as possible, try cutting out substances that can stain them. Wine, cigarette smoke, tea and coffee can all discolour teeth. Keep these to a minimum or cut them out completely to stop your teeth from becoming stained.

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.
