While Layer 1 is selected, select the symbol with the rectangle with a circle in the middle. This symbol represents the Layer Mask. The Layer Mask allows information to temporarily be erased or recovered at any time.
Now, notice how a white layer has appeared next to Layer 1.
To hide unwanted spots around the tooth, locate the left side of the workspace where the Tool Bar is located.
Within the Tool Bar, the Brush Tool is located underneath the Eyedropper Tool and is recognizable by a brush shaped symbol.
Select the Brush Tool by clicking or by hitting B on the keyboard.
If black is not already selected as the foreground color, locate the bottom of Tool Panel.
Notice how there are two colored boxes.
The color on the top represents the foreground color and the color beneath it represents the background color.
This is the Default Foreground and Background Colors button.
If the colors are not set as black as the foreground as the background and white, simply click on the symbol or hit D on the keyboard, which will apply the default colors.
Locate the top of the workspace and customize the Brush options as desired.
Once the desired Brush settings are selected, click and drag the mouse over the unwanted spots while painting with black.
Notice how the areas painted with black in the layer mask disappear.
To make hidden areas of the layer mask visible again, hit X on the keyboard to change the foreground to white.
Simply click and drag the mouse over the areas desired.
While white is selected, click and drag the mouse over the desired area.
Once the tooth is naturally blended in, hit Option or ALT and click to zoom out on the keyboard to view the finished product.
