Enamel Regeneration
Amelogenin-Derived Peptides
P11-4 · Emdogain (EMD) · LRAP
Biomineralization signal peptides that mimic the body's own enamel matrix proteins, directing calcium and phosphate ions to rebuild hydroxyapatite crystal structure — regenerating enamel from within a lesion without drilling.

What It Is & How It Works
What is it?
Amelogenin-derived peptides are short sequences derived from the enamel matrix proteins that orchestrate tooth development. P11-4 (commercially available as Curodont Repair) is a self-assembling peptide that creates a scaffold mimicking the enamel matrix, directing mineral ions to rebuild hydroxyapatite crystals from within a lesion.
How does it work?
When applied to an early carious lesion, P11-4 diffuses into the subsurface demineralized zone and self-assembles into a fibrous matrix. This matrix acts as a nucleation scaffold, attracting and organizing calcium and phosphate ions from saliva into new hydroxyapatite crystals — rebuilding enamel from the inside out without any tooth preparation.
Dental application
Emdogain (EMD) serves a related role in periodontal surgery — it re-creates the enamel matrix environment on root surfaces to regenerate lost periodontal attachment, new cementum, and alveolar bone. Both peptides are applied by your provider in-office as part of your treatment.
Key Benefits
- Arrests and reverses early-stage enamel caries (ICDAS 1–2) without drilling or restoration
- Rebuilds hydroxyapatite crystal structure from the subsurface — true regeneration, not just surface remineralization
- Emdogain promotes regrowth of periodontal attachment, new cementum, and alveolar bone after periodontal surgery
- Clinically validated in multiple randomized controlled trials
- Single in-office application — no ongoing home regimen required for P11-4
Key Benefits
In-Office Topical Application
Applied directly to the tooth surface or root during your appointment — no injections, no take-home protocol required.
Periodontal Surgical Application
Emdogain gel is applied to root surfaces during regenerative periodontal surgery as part of your procedure.
Note: These peptides are applied exclusively in-office by your Core Smiles provider as part of your scheduled dental treatment. No self-administration is required.
Possible Side Effects
- Mild sensitivity at application site (transient)
- Rare: minor gingival irritation
- No systemic side effects reported
- No known drug interactions
Important: Amelogenin-derived peptides have an excellent safety profile with over two decades of clinical use. Emdogain is contraindicated in patients with known hypersensitivity to propylene glycol alginate. Please inform your provider of any known allergies.
What to Expect
P11-4 is applied in a single in-office visit. Radiographic evidence of remineralization typically becomes apparent within 3–6 months and is monitored at your recall appointments. Emdogain supports periodontal regeneration progressively over 6–12 months following surgery, as new attachment tissue forms and matures.
Regulatory Status
Emdogain (Straumann) is FDA-cleared for use in periodontal regenerative procedures. P11-4 (Curodont Repair, credentis AG) is CE-marked in Europe and available in the United States through select providers as a professionally applied remineralization treatment. Your provider will discuss current availability at consultation.
