Cavity Prevention in Amstelveen: How to Stop Tooth Decay Before It Starts

Tooth decay — also called dental caries — is one of the most widespread chronic health conditions worldwide, yet it is almost entirely preventable. The bacteria in your mouth feed on sugar and produce acids that dissolve tooth enamel. Given time, this creates a cavity that may require a dental filling. Understanding this process is the first step to stopping it.

At Dentinn Amstelveen, Dr. Fatma Boydas believes that prevention is always better than treatment. Here is a practical, evidence-based guide to keeping cavities away.

How Tooth Decay Actually Happens

Tooth decay is not caused by sugar alone — it is caused by the acid produced by bacteria that consume sugar. The process works like this:
1. Bacteria in your mouth (primarily *Streptococcus mutans*) feed on carbohydrates and sugars
2. They produce lactic acid as a byproduct
3. This acid lowers the pH in your mouth and attacks the mineral structure of enamel
4. If acid attacks happen more often than the mouth can remineralise (neutralise and repair), enamel weakens and a cavity forms

This is why frequency matters as much as amount. Sipping sugary drinks throughout the day — even juice — keeps your mouth in a constant acid state. Eating sweets at one sitting is less damaging than spreading them out.

The Role of Fluoride

Fluoride is the single most effective tool for cavity prevention. It works in two ways:
- Remineralisation: fluoride helps deposit minerals back into weakened enamel, reversing early decay before a cavity fully forms
- Bacteriostatic effect: high concentrations of fluoride directly inhibit the acid-producing bacteria

In toothpaste: use a fluoride toothpaste with at least 1000 ppm (parts per million) for adults. For children under 3, 500–1000 ppm; from age 3, 1000 ppm; from age 6, the same as adults.

After brushing: spit, but do not rinse. Leaving a thin film of toothpaste on your teeth extends the fluoride contact time — one of the simplest habit changes that makes a measurable difference.

Professional fluoride treatments: at Dentinn, we apply concentrated fluoride varnish (22,600 ppm) to the tooth surfaces twice a year for patients at higher risk. This takes about two minutes and provides protection that home fluoride cannot replicate.

Diet: The Biggest Modifiable Risk Factor

You do not need to eliminate sugar entirely to prevent cavities — but frequency and form matter:
- Reduce frequency: limit sugar and acidic foods to mealtimes. Each time you eat or drink something sugary, you trigger a 20–30 minute acid attack. Three sugar exposures a day (at mealtimes) is far safer than continuous snacking
- Water as the default drink: water — especially fluoridated tap water — is the best drink for your teeth between meals. It does not trigger acid, it washes food away, and it stimulates saliva
- Avoid acidic drinks: citrus juice, sports drinks, and fizzy water are acidic even without added sugar. Drink them at mealtimes and through a straw when possible
- Cheese and dairy: excellent for teeth. Cheese stimulates saliva and raises the pH of the mouth. Eating a small piece after a meal helps neutralise acid
- Xylitol: a natural sweetener that bacteria cannot ferment into acid. Chewing xylitol gum after meals stimulates saliva and provides active cavity protection

Brushing Technique: Small Changes, Big Impact

Most people brush — but not necessarily effectively. Common mistakes:
- Brushing too hard: aggressive brushing wears away enamel and causes gum recession. Use gentle circular or sweeping movements
- Brushing too briefly: aim for two full minutes, twice a day. Most people brush for under 45 seconds
- Missing the back teeth and gum line: these are the most cavity-prone areas and are often rushed through
- Rinsing with water immediately after: this washes away the fluoride before it can act. Spit, do not rinse

An electric toothbrush is clinically proven to remove more plaque than a manual brush for most users. If you are unsure about your technique, ask our dental hygiene team for a personalised demonstration at your next check-up.

Flossing and Interdental Cleaning

Brushing cleans only about 60% of tooth surfaces. The remaining 40% — the spaces between teeth — can only be cleaned with floss or interdental brushes. Cavities between teeth (interproximal caries) are extremely common and are the type most likely to be missed until they become significant.

Floss once a day, ideally at night. If floss is difficult to use, interdental brushes (in the right size for your gaps) are an equally effective alternative. Our dental hygienist can advise on which size fits your teeth.

Professional Treatments That Prevent Decay

Beyond home care, Dentinn offers several professional preventive treatments:
- Fluoride varnish: concentrated fluoride applied to all tooth surfaces. Takes 2 minutes; provides months of enhanced protection
- Fissure sealants: a thin resin coating placed in the deep grooves of back teeth where bacteria accumulate and brushing cannot reach. Highly effective for children and teenagers, and available for adults with deep fissures
- Risk assessment and monitoring: we track areas of early demineralisation (white spots) at each check-up. Catching decay at this stage allows remineralisation without any drilling

When to See the Dentist Even Without Symptoms

Cavities do not usually cause pain in their early stages. By the time a tooth hurts, decay has often reached the deeper layers of the tooth — at which point you may be looking at a root canal treatment rather than a simple filling. Regular check-ups every 6 months — as described in our guide on what happens at a dental check-up — allow us to find and treat small cavities before they become large ones.
