Enamel – the hardest tissue in the human body, but unfortunately prone to damage.
Enamel is the outer layer of the tooth that protects it from damage. It is the hardest tissue in the human body, but unfortunately it is also prone to damage.
Causes of enamel damage:
- Acids: Acids in foods and drinks, such as citrus fruit, fizzy drinks or vinegar, can weaken enamel.
- Bacteria: Decay-causing bacteria produce acids that dissolve enamel.
- Injury: An injury, such as a knock to the tooth, can damage the enamel.
Effects of damaged enamel:
- Sensitivity: Damaged enamel can make teeth sensitive to hot, cold, sweet or sour foods.
- Tooth decay: Damaged enamel is more prone to decay.
- Cracks: Damaged enamel can crack, which may lead to tooth loss.
It is important to protect enamel from damage, because it is the layer that protects the tooth from decay and other problems.
What is tooth enamel mineralisation?
Mineralisation is the process in which enamel and dentine are hardened by minerals such as calcium, phosphorus and fluoride. This process starts before birth and continues throughout life.
Enamel is the outer layer of the tooth and the hardest tissue in the human body. Dentine is the inner layer of the tooth; it is less hard than enamel but still very strong.
Tooth mineralisation is important because it helps protect teeth from damage, such as decay and sensitivity.

Factors that can disrupt tooth mineralisation include:
- Poor diet: A diet low in calcium, phosphorus and fluoride can make enamel mineralisation harder. It is also worth remembering the negative effect of acids on enamel. Eating a lot of sweets or sour foods can cause enamel loss.
- Poor oral hygiene: Not removing plaque can lead to tooth decay, which can damage enamel and dentine.
- Some diseases: Some conditions, such as diabetes and kidney disease, can make tooth mineralisation harder.
To support proper tooth mineralisation, follow these rules:
- Eat a diet rich in calcium, phosphorus and fluoride.
- Brush your teeth and tongue regularly.
- Visit your dentist regularly.
How do enamel-repairing toothpastes work?
Enamel-repairing toothpastes contain ingredients that help fill in tiny defects in the enamel. As a result, they also help prevent decay and reduce tooth sensitivity. Their main job is to strengthen and repair enamel and protect the teeth.
What active ingredients do enamel-repairing toothpastes contain?
Enamel-repairing toothpastes most often contain the following active ingredients:
- Fluoride – the most common active ingredient in enamel-repairing toothpastes. Fluoride can form a protective layer on the enamel surface that protects it from acids.
- Hydroxyapatite – hydroxyapatite particles are similar to the natural components of enamel. When applied to the teeth, they bind to them and form a new protective layer.
- Calcium – a mineral essential for the healthy development and maintenance of enamel.
- Phosphorus – another mineral that supports the repair of the enamel surface.
- Zinc – may help with enamel remineralisation.
Which enamel-repairing toothpaste should you choose?
When choosing a strengthening toothpaste, consider the following:
- Active ingredients: The toothpaste should contain at least one of the following active ingredients: fluoride, hydroxyapatite particles, calcium, phosphorus or zinc.
- Fluoride or hydroxyapatite: Check which of these ingredients the toothpaste contains and use it as the manufacturer recommends. If you are not sure which option suits you, ask your dentist.
- Additional active ingredients: Some remineralising toothpastes also contain other active ingredients, such as xylitol, which reduces plaque, or menthol, which leaves your mouth feeling fresh.
