The short answer
For a whitening tray, place a small drop of the prescribed gel in the front portion of each tooth compartment, following the product instructions rather than filling the tray.

What is the direct answer?
What does this question mean?
Whitening gel usually contains a peroxide such as carbamide peroxide or hydrogen peroxide. The tray holds the gel against the tooth surface, while excess gel can spill onto the gums and irritate them.
What can you do next?
Use a clean, dry tray, load only the compartments for the teeth being treated, seat it gently, and wipe away visible gel from the gumline. Use the concentration and wear time supplied for that product, and stop if marked gum burning or tooth pain develops.
When should you seek dental care?
Ask a dentist or the product prescriber for instructions before use if the tray does not fit, the gums bleed, teeth have untreated decay, or you have restorations in the visible area. Seek care for persistent gum injury or severe sensitivity.
What should you ask the dentist?
Ask which peroxide concentration you have, how long each session should last, whether every compartment should be loaded, and how to store the gel and clean the tray.
