Preventing Tooth Decay: Key Facts
Tooth decay is one of the most common chronic diseases in Australia but is almost entirely preventable. Caused by diet-related factors, it occurs when acids produced by bacteria attack and weaken the enamel. With proper care, tooth decay can be stopped in its early stages, preventing the need for fillings.
How Tooth Decay Occurs
Tooth decay is caused by a combination of factors:
- Bacteria in the mouth (e.g., Streptococcus mutans) use sugar from food and drinks to produce acid.
- This acid dissolves minerals in tooth enamel in a process called demineralisation.
- Without sufficient protection, such as saliva and fluoride, frequent acid attacks weaken teeth and lead to decay.
- Saliva and fluoride play a key role in remineralising and repairing teeth, balancing the effects of harmful acids.
Risk Factors for Tooth Decay
Factors that increase the risk:
- Poor oral hygiene
- Sugary foods and drinks
- Frequent snacking
- Hidden sugars in processed foods
- Reduced saliva flow
Factors that protect your teeth:
- Brushing twice daily with fluoride toothpaste
- Flossing or cleaning between teeth
- A diet low in sugar
- Sufficient saliva production
- Regular dental check-ups
Tips to Prevent Tooth Decay
The Australian Dental Association recommends four simple steps:
- Brush twice daily with fluoride toothpaste. Don’t rinse your mouth after brushing to allow fluoride to protect your teeth longer.
- Clean between teeth daily using floss or interdental brushes.
- Adopt a tooth-friendly diet, limiting sugary snacks and drinks. Choose water and fresh fruit over sugary alternatives.
The Role of Diet in Tooth Decay
Sugary foods and drinks, such as soft drinks, energy drinks, and sweets, increase your risk. Even some seemingly healthy options, like cereal, bread, and sauces, can contain hidden sugars.
Tooth-friendly options include:
- Fresh fruit (preferable to dried fruit or fruit juice)
- Dairy products like milk and cheese, which contain protective minerals
- Tap water, often fortified with fluoride to strengthen teeth
Treating Tooth Decay
If decay is detected early, your dentist can help stop its progression, avoiding the need for a filling. However, advanced decay requires treatment, where the damaged area is removed and replaced with filling material.
