Have you ever taken a great photograph but became ashamed of your braces? Well, have no fear! Photoshop can fix it.
Once you have your image ready, select the Clone Stamp Tool (S).
Choose a soft round brush. Size depends on the size of the area you're working on. Zoom into the area as much as you need.
Hold Alt and click on an area above the bracket. Make sure you're not too close but not far away either.
Brush on the bracket and if you need to, Alt-Click other blank areas to keep brushing the bracket out. You may need to Alt-Click on other cleared out teeth to clear out hard to get spots.
Do this on the remaining teeth until you clear them all out.
