Aha! So, rapid fluid movement within the dentin tubules is the culprit that causes teeth to be sensitive to thermal, evaporative, tactile, osmotic, and chemical stimuli. And double-block technology will stop the pain in its tracks? Very interesting!
Let me explain. “Double-block” technology is the superpower behind Shield Force Plus from Tokuyama. When Shield Force Plus is applied to tooth surfaces, it penetrates deep down into the dentin tubules, causing a reaction between the monomer and the calcium in the tooth that results in the formation of resin tags—block #1. The uniform 10-µm layer of sealant that remains on the tooth surface, effectively shielding the filled tubules—block #2—creates a very durable coating after being air dried and light cured. Like the bottle, Shield Force is green, until light cured, for easy visualization. This pain-saving shield resists abrasion and erosion, protects the tooth from bacteria, and will continue to provide desensitization for up to 3 years.
Just another way you get to be the hero!
