This is a little round mouth mirror. Their primary function is to allow the dentist to take a deep look. It pushes your cheek and tongue out of the way to look at the hidden spots. It also shines light into dark corners of your mouth. This helps the dentist spot any tiny cracks that are hard to see.

The explorer is a small, pointy tool that makes many people worried. But its sharp tip is not to hurt. A dental explorer is a tiny finger that helps to feel the surface of your tooth. It slides across your enamel and reads the sticky or rough spots — early signs of a cavity. A dentist can find problems without causing pain.

A periodontal probe can be scary, but it's a tiny ruler with a simple job — to measure the space between your tooth and gum. Healthy gums have small, shallow pockets. The numbers you often hear from dentists are measurements. They tell how strong and healthy your gums are.

The dental excavator is a spoon-shaped tool. It helps to scoop out the soft and decayed part of the tooth — the same as removing the brown and mushy spot from an avocado. The dentist can extract only the bad part, leaving behind the healthy and strong structure.

Three tools that work together to fill and shape your tooth. The amalgam carrier delivers the filling material and places it into the clean cavity. The condenser or plugger pushes the filling down so it sits tightly and leaves no air pockets. Finally, the carver shapes the filling to match the natural shape of the tooth.

After the filling is in place, the burnisher polishes it smooth and flat. It rubs across the filling to make it shiny and even — comfortable against your tongue and the tooth next to it. It also ends the rough spots where food and plaque could get stuck.

When you have a cavity on the side of a tooth, the dentist needs a wall to build the filling against. The matrix band wraps around your tooth and acts like a perfect temporary mold. It holds the filling material in place and makes it easy for a dentist to rebuild the tooth's natural shape.

This tool makes a high-pitched sound that many people notice soon. The patient also feels a spray of water acting as a coolant to keep the tooth from getting too hot. You do not feel pain — only pressure and light vibration. These are signs that the tool is working to fix the problem.

This one is different — with a deeper hum and slow feeling. It gives a gentle shaking and vibration when the dentist uses it to clean out soft decay. It does not cut fast, but works slowly and carefully. This is a finishing tool that makes everything smooth and shiny.

This dental tool uses fast buzzing vibrations to break up tartar that is stuck. It creates a high-frequency buzz and a cool feeling from a spray of water. The water is not only splashing — it also washes and keeps your tooth cool. It has no pain but feels like a tickling sensation.

This thin, stretchy rubber dam sheet might look odd, but think of it as your personal safety net. It fits around your tooth and catches tiny pieces so nothing falls to the back of your throat. It also keeps the tooth very clean and dry, which helps fillings and root canals last longer.

These two tools keep your mouth dry during treatment. The strong, loud one sucks up water and tiny bits while also holding your tongue or cheek out of the way. The quiet, curvy one rests in your mouth to remove extra saliva.

Holding your mouth open for a long time can make your jaw tired and sore. This soft tool is a comfy cushion that holds your mouth open for you. You rest your teeth on it and let your jaw muscles relax. It gives your muscles a break so the dentist can work without you feeling worn out.
