Dentist Explains: How To Fix A Cavity !?

Here's how a dentist fixes cavities. First, we isolate the tooth and protect the gum. Then, carefully remove all the rot and the previous silver filling.

Smooth in the edges. Clean out the root. Seal the canals.

Then, slowly fill up the base with the dental glue. Next, we need to use a metal band to hold everything together. Time to use a blue light to help that glue harden.

Now, we'll add some more dental composite and shine the blue light to cure it. Let's remove the metal band and polish that tooth so it's smooth. Using a 3D scanner, we can make a new piece of the tooth that will fit in like a puzzle piece.

But first, we need to add the liquid cement. Smush it. Clean up the edges.

Hit it with a quick blue light to harden the cement. And just like that, you have a fully restored smile.
