Most of the gels or pastes we use just sit on the surface. They don&rsquo;t really get deep enough to plug the leak, which is why the sensitivity keeps coming back. We found a better way. We use infrared (IR) light to basically &ldquo;push&rdquo; the medicine deeper into the tooth. <strong>How it actually works</strong> Think of it like this: when we hit the tooth with infrared waves, it creates a bit of localized heat. That heat thins out the desensitizing medication—making it less thick and more fluid. Because it&rsquo;s thinner, the medicine slides way deeper into those tunnels than it ever would if it were cold. It’s a simple trick of physics, but it means the seal is much tighter and lasts longer. <strong>The &ldquo;Sweet Spot&rdquo; for Heat</strong> Now, you can&rsquo;t just blast the tooth with heat. If you go overboard, you&rsquo;ll kill the pulp, and nobody wants that. That&rsquo;s why we stick to the near-infrared (NIR) spectrum. It’s a specific wavelength that targets the water in the tooth just enough to get the medicine moving, but keeps everything at a safe temperature. You just have to keep an eye on your power settings to make sure the heat stays controlled. <strong>The Real-World Stuff</strong> The best part? It&rsquo;s fast. Your patients get out of the chair sooner, and you get your day back. There are a couple of things to keep in mind, though. The gear takes up a bit of extra space on your counter. Also, every tooth is different. If you&rsquo;re dealing with really dense enamel, you might need to leave the light on a few seconds longer than you would for more porous dentin. My advice? Hook it up to a precision timer. It takes the guesswork out of it so you never have to worry about over-exposing the tooth.</p>
