Tooth decay (dental caries) is the destruction of your tooth enamel (the hard, outer layer of your teeth) and is produced by harmful bacteria. There exists an active relationship between sugars and oral health problems.

Consumed sugar may occur naturally in food or be an additive. But sugar isn’t the only culprit!

So, aside from sugar, what causes tooth decay? Multiple factors in addition to sugar affect the tooth decay process. These include the type of food and duration of exposure, but sugar is the cornerstone of decaying teeth. Medical research has shown a direct link between dietary sugar and dental decay.

The cost of tooth decay

Tooth decay has a huge financial and social burden. It is common in developed nations due to the sugar-rich diet prevalent in those countries (like right here in Australia). The latest data shows that 72,000 hospitalisations for dental conditions could have possibly been avoided with earlier treatment and care.

Dental check up

Tooth decay is characterised by the destruction of tooth enamel; it involves the presence of oral bacteria and a sugar-rich diet. The degree of deterioration is affected by the level of oral hygiene and genetic factors. Preventing poor dental health starts by focusing on eliminating or minimising sugar intake as well as having regular dental check-ups.

Examples of high-sugar foods and drinks are:

  • Confectionary
  • Cakes
  • Biscuits
  • Exfoliate lipsSweetened cereals
  • Sweet desserts
  • Sucrose
  • Honey
  • Sugary drinks like soda
  • Fruit juices

Are your sugary drinks really worth it?

What does sugar do to your teeth? When you consume sugar, it reacts with bacteria present in the dental plaque. This bacteria —for example, Streptococcus — metabolises sugar to produce organic acids.

The ideal pH for normal teeth health is above 5.5. The organic acids produced from the metabolism of sugar makes the pH of the teeth environment fall below 5.5. These harmful bacteria feed and cause demineralisation of the enamel leading to tooth decay.

In contrast, a low sugar diet favours remineralisation of the enamel.

Tooth decay is characterised by painful and sensitive teeth. Sensitivity may be experienced during biting or drinking cold or hot foods and drinks. When tooth decay is not managed in time, it leads to the formation of cavities that expose the tooth pulp to armful bacterial infection and, when left untreated, can start to affect deeper layers, leading to tooth abscesses and other overall health issues. This can be properly prevented through good oral hygiene and being mindful of added sugars.

How to prevent tooth decay?

To prevent tooth decay, advanced gum disease, tooth loss, or tooth discolouration, the following tips would help a great deal, especially if you eat sugary foods, sugar-sweetened beverages, drink soft drinks and other high sugar foods and drinks.

  1. Use fluoride toothpaste irrespective of whether you live in a fluoride-rich area or not.

  2. Eliminate or limit the amount and frequency of soft drinks to minimise tooth decay and prevent harmful bacteria.

  3. Don’t sip sugary soft drinks. Try drinking with a straw to minimise sugary drink contact with your teeth.

  4. Exercise good oral health and brush and floss your teeth twice daily because the harmful bacteria produce acid, which attacks your teeth.

  5. Regular dental visits.

  6. Restrict the amount of how much sugar you add to beverages and restrict sugary foods eaten by keeping it to mealtimes rather than regular snacks.

  7. Chewing sugar-free gum between meals to increase saliva production.

  8. Eat dairy foods like cheese after consuming fermented carbohydrates and others sugars.

  9. Don’t forget to drink plenty of water.

High sugar diets mean no sparkling white smile

Sugar itself can’t stain your teeth, but it can be the catalyst to tooth discolouration or even gum disease. Tooth decay occurs when you consume sugary treats; the bacteria that helps digest the sugar in your mouth can erode your teeth enamel. When sugar is left on your teeth, this can lead to your dentin becoming exposed, yellowing your smile.

Fight your sugar cravings with nutritious foods like organic dates, fruits, etc. These foods are not only sweet and delicious but also rich in essential minerals.

So, what can be done about this discolouration? Luckily for you, PureSmile offers a vast range of teeth whitening options.
