Explaining Tooth Decay with the Australian Dental Association.

• Millions of bacteria live inside the human mouth. Sugar from the foods and drinks we consume feeds some of these bacteria, giving them energy to produce acid.
• This acid attacks the surface of the teeth, causing enamel minerals to dissolve. This is called demineralisation.
• Together, saliva and fluoride toothpaste protect the teeth by neutralising the acids and replacing the lost enamel minerals. This is called remineralisation.
• By regularly consuming sugary foods and drinks, the saliva and fluoride toothpaste may not be able to keep up in replacing the lost tooth minerals.
• When tooth mineral loss outweighs mineral replacement, this can result in tooth decay.
• If tooth decay is only in the enamel layer, it can still be stopped.
• Once it travels to the inner dentine layer, the tooth may require a filling.
• Remember to look out for foods with hidden sugars, eat a diet low in sugar, and brush twice daily using fluoride toothpaste to decrease your risk of developing tooth decay,
• and visit your dentist regularly to prevent problems and keep on smiling.
