Goal
Create a durable, non-stick surface on natural teeth, dentures, implants and restorations that prevents plaque, stains and acid damage for up to six months.
Problem
Dental plaque buildup, staining, acid-induced caries and tooth sensitivity; difficulty of adhesives on non-stick silicone surfaces.
Concept Summary
A self-bonding silicone polymer gel (polydimethylsiloxane) is applied to a tooth surface where it catalytically polymerises into a three-layer structure (methyl top layer, silicone mid-layer, oxygen bottom layer) that bonds to the substrate and renders the surface inert, non-adhesive to plaque and acidic foods.
Detailed Description
KISSCare Ultra is a tasteless, non-toxic, non-flammable silicone polymer gel composed of pure polydimethylsiloxane (dimethicone). When applied with a cotton swab, floss or prophy cup, the gel cures at ambient temperature (or mild heat) to form a thin inert silicone coating. The coating consists of a methyl-rich outer layer, a silicone middle layer and an oxygen-rich interfacial layer that chemically bonds to enamel, denture acrylic, or implant metal. The cured surface is hydrophobic, resists bacterial adhesion, acid attack and staining, and also acts as a desensitiser. Application of a full arch takes less than ten minutes and the coating remains effective for up to six months before re-application is needed. The product is sold by WDR Scientific and is classified by the US FDA as GRAS.
Principles
- Self-bonding polymerisation of dimethicone
- Surface modification creating a hydrophobic, inert silicone layer
- Catalytic cross-linking inhibition to control surface adhesion
Scientific Domains
Materials
- Polydimethylsiloxane (dimethicone)
- Silicone polymer gel
- Cross-linking inhibition agents (e.g., cyanoacrylate polymers, stannous octoate)
Mechanisms of Action
- Hydrophobic non-stick surface prevents plaque adhesion
- Acid-resistant silicone layer reduces enamel demineralisation
- Oxygen-rich interfacial layer bonds chemically to tooth substrate
- Desensitising effect via barrier to fluid movement
Applications
- Dental plaque prevention
- Tooth desensitisation
- Stain resistant coating for dentures and implants
Claimed Performance
Provides a non-stick, acid-resistant surface that protects teeth and dentures for up to six months; reduces plaque formation and stains; acts as a desensitiser.
Experimental Evidence
British Dental Journal (June 2014) reported that KISSCare Ultra seals and protects natural teeth and dentures from stains, sticky foods and plaque for up to six months; the product also resists acid and reduces sensitivity on bleached teeth.
Replication Status
Product is commercially available from WDR Scientific; no independent peer-reviewed replication beyond the cited journal study.
Limitations
- Does not replace regular oral hygiene
- Coating efficacy declines after ~6 months, requiring re-application
- Not evaluated by FDA for disease treatment
Red Flags
- Product has not been evaluated by the US FDA for therapeutic claims
- Claims of up to six-month protection are based on limited clinical data
