If you are a teenager or young adult, you need to protect your mouth and teeth by maintaining good oral health. Although regular brushing and flossing are important, the oral health of those in this age group is also often associated with risk factors such as diet, smoking and alcohol and mouth and tongue piercings.
Cavities (tooth decay)
Anyone who has teeth can get cavities, including teenagers and older adults.
When you consume food and drinks that are sugary or starchy (high in carbohydrates), the bacteria that naturally live in your mouth and in plaque, break down to form acids. These acids attack and dissolve the outer surface of the tooth (enamel). This process is known as demineralisation.
The first sign of demineralisation is a chalky white spot. At this stage, the decay process can be reversed. If you suspect you have the start of tooth decay, make an appointment to see your dentist.
