Reparieren of tooth enamel: 
The truth about fluoride, hydroxylapatite, and genuine repair

Enamel is the hardest substance in the body – but not indestructible. Acids, mechanical stress, and modern diets cause microscopic defects on the surface daily, which can worsen over time. 

Structural weaknesses develop, leading to cavities and noticeable effects: sensitivity, pain, and a visible loss of shine and brightness.

The Fluoride Myth: 
Protects teeth but does NOT make them harder

Fluoride does not make teeth harder – this is a common misconception. Fluoride forms a calcium fluoride layer on the tooth surface, which:

• Protects against acids (temporary protective film)

• Promotes remineralisation from saliva

• Needs to be rebuilt twice daily during brushing

• Is not stable and dissolves again

Fluoride is an important protective factor, but it cannot repair structural defects. The calcium fluoride layer is like a daily umbrella – important, but not permanent.

Real Tooth Enamel Repair: 
Liquid Enamel (Hydroxylapatite)

Hydroxylapatite is the natural fundamental component of tooth enamel (96% of the enamel). In submicroscopic form, it can:

• Permanently fill micro-defects

• Be incorporated into the tooth structure

• Smooth out deep roughness

• Provide structural repair instead of just surface protection

Why submicroscopic is crucial

Normal Hydroxylapatite particles do not adhere. Submicroscopic ApaCare particles (Liquid Enamel):

• Penetrate microcracks,

• Adhere to natural tooth enamel

• Are integrated into the tooth substance

• Do not dissolve through saliva or brushing

The perfect combination: 
Fluoride + Hydroxylapatite

Why ApaCare contains both

Fluoride and Hydroxylapatite complement each other ideally:

1. Fluoride forms the daily protective layer (Calcium fluoride)

2. Hydroxylapatite provides long-lasting structural repair

3. Together they create maximum protection + genuine regeneration

The ApaCare innovation: 
Both active ingredients in one tube

Normally, fluoride reacts immediately with Hydroxylapatite in the tube. The ApaCare technology protects the fluoride from this reaction – only on the teeth can both active ingredients work optimally.

Multi-stage Enamel Repair

Stage 1: Daily Protection + Repair (ApaCare Toothpaste)

• Fluoride daily builds up the calcium fluoride layer

• Sub-microscopic Hydroxylapatite continuously repairs micro-defects

• 2-3 times daily for lasting protection and regeneration

Stage 2: Intensive Repair (ApaCare Repair Tooth Repair Pastes)

• Highly concentrated Hydroxylapatite without abrasive particles

• Applied after brushing for extended contact time

• Repairs larger defects and sensitivities

Stage 3: Maximum Intensity (ApaCare Repair + ApaCare Repair Dental Splint)

• Longest contact time for severe cases

• Molar incisor hypomineralisation (MIH), white spots, orthodontic or erosive lesions

• For painful tooth necks

• Gentle whitening

• 20 minutes or overnight

Immediately noticeable results

The ApaCare feeling: scientifically explainable

Patients immediately notice the extraordinarily smooth teeth:

• Sub-microscopic surface densification

• Enhanced light reflection for natural shine

• Anti-adhesive effect – bacteria bead off

• Reduced plaque adhesion

Desensitisation: Immediate and permanent

Sensitive teeth are treated immediately:

• Dental tubules are sealed (not just covered)

• Fluoride supports sealing

• Permanent solution instead of daily symptom management

Molar incisor hypomineralisation: When normal repair is not enough

MIH: Structural enamel disorder

Molaren-Inzisiven-Hypomineralisation means defective enamel from birth:

• Porous, soft structure

• Extreme sensitivity

• High susceptibility to caries

• Discolorations and substance loss

ApaCare MIH Set: Biomimetic support

Developed specifically for hypomineralised teeth:

• Stabilises defective structures

• Functional regeneration of enamel

• Significantly reduces sensitivities

• Suitable for children under 6 years old

Appearance: Naturally white teeth without destruction

Bleaching vs. ApaCare: The key difference

Traditional bleaching:

• Roughens the surface

• Makes teeth porous

• Temporary effect

• Weakens the tooth structure

ApaCare Repair:

• Densifies the surface

• Optimises light reflection

• Permanent effect

• Strengthens the tooth structure

International leading research with extensive data: Numerous peer-reviewed studies, culminating in a Nature Scientific Reports publication, demonstrate:

• Repeated repair of existing enamel defects

• Cross-study confirmed regression of micro-lesions

• Consistent documented structural regeneration with optimal contact time

Who benefits from genuine enamel repair?

Everyday stresses

• Acidic diet (fruit, wine, soft drinks)

• Coffee, tea, red wine (discolorations + acids)

• Stress-related teeth grinding

• Mouth breathing (sports, snoring)

Special indications

• Sensitive teeth and exposed tooth necks

• Molar incisor hypomineralisation (MIH) in children

• White spots after braces

• Initial caries (early decay)

• After bleaching treatments

The Future of Dental Care: Repair Instead of Just Protection

Fluoride remains important for daily protection – but true enamel repair goes far beyond that. With submicroscopic Hydroxylapatite, symptom treatment becomes real regeneration.

ApaCare – Where Protection Meets Repair.

Can enamel truly be repaired?

Yes, enamel can be repaired! Using submicroscopic hydroxylapatite (liquid enamel), microdefects, roughness, and even early caries can be structurally repaired. Studies, including one in Nature Scientific Reports, demonstrate the regression of micro-lesions with sufficient contact time.

How long does enamel repair take?

The ApaCare sensation is immediately perceptible – teeth feel smoother after the first application. Visible improvements appear after 1-2 weeks of regular use. Structural repair of microdefects occurs continuously over several weeks.

Is enamel repair permanent?

Studies have shown that repaired enamel areas can remain stable. Hydroxylapatite adheres to damaged tooth structure, fills microdefects, and can remain permanently in place.

In everyday use, enamel is still exposed to stresses. Regular care helps maintain the achieved stability and prevents new defects.

What is the difference between fluoride and hydroxylapatite?

Fluoride provides protection, hydroxylapatite repairs: Fluoride forms a temporary calcium fluoride layer that must be renewed daily. Hydroxylapatite is the natural building block of enamel and can perform permanent structural repairs – defects are filled and integrated into the tooth substance.

Does enamel repair help with sensitive teeth?

Yes, very effectively! Submicroscopic hydroxylapatite permanently seals exposed dentinal tubules – not just superficially. Sensitivity relief occurs immediately and persists as particles are incorporated into the tooth structure and do not dissolve in saliva.

Does enamel repair work for chalky teeth (MIH)?

Especially well! Chalky teeth have defective, porous enamel from birth. The ApaCare MIH set was specifically developed for hypomineralised teeth and can stabilise and functionally regenerate the damaged structures. Suitable for children under 6 years old as well.

Can I buy enamel repair in Berlin/Munich/Hamburg etc.?

Yes, available throughout Germany! ApaCare products can be obtained at pharmacies, drugstores, and online. Direct order via www.apacare.de with international delivery

Is enamel repair better than bleaching?

ApaCare Repair consolidates the surface and optimises light reflection for a natural shine – without destroying the tooth substance. The effect is permanent and strengthens the teeth, while the natural tooth colour is improved. Bleaching, on the other hand, is more intensive but roughens the surface and attacks the enamel.

Where can I find a dentist for enamel repair near me?

Many dentists in Germany, Austria, and Switzerland work with ApaCare products. Look for practices specialising in prophylaxis or paediatric dentistry (for MIH). Ask your local dentist directly about experiences with ApaCare-based repair systems.

Can white spots disappear again?

Yes – in the early stages, white spots can be stabilised and partially reversed, as the surface is still intact.
Targeted remineralisation with liquid enamel can help compensate for mineral losses and make the surface appear more even again.

Who benefits most from enamel repair?

Especially for:

• Sensitive teeth

• Increased susceptibility to caries

• White spots after braces

• Acidic diet

• Chalky teeth (MIH)

• Post-bleaching

Is ApaCare Repair useful with braces (orthodontics)?

Yes. Braces create hard-to-clean areas where the enamel can weaken (white spots).

ApaCare Repair can support here by allowing hydroxylapatite to adhere, compensating microdefects, and stabilising the surface.

Especially beneficial during and after treatment.
