Step 1
Consider disposable bleaching trays if you want the least expensive system that also works faster than most systems. Crest White Trays® are pre-filled with a glycerin based gel containing hydrogen peroxide and costs around $35 to $42 for a 14-tray pack.

Step 2
Buy disposable pre-filled bleaching trays at most pharmacies and drug departments. Use the trays once a day for 30 to 45 minutes for five to seven days.

Step 3
Warm Trays Before/AfterBuy a "warm tray" system from an online source to get a semi-custom fitting set of bleaching trays. Warm trays are molded to fit by dipping in hot water to soften them, then pressing them over your teeth. Warm trays cost around $38 to $55 with whitening gel syringes and shipping charges. Warm trays are worn one to three hours daily for one to two weeks.

Step 4
Molding Tray with PuttyBuy a custom-molded bleaching tray system if you want a more precision fit to your trays. For custom trays, you have to mix a molding putty, press it into molding trays and make bite molds of your upper and lower teeth like the kind the dentist makes. Send the molds back to the laboratory and they send your custom trays in a week or two.
-
Step 5
Find custom molded bleaching trays on the Internet for prices ranging from $60 to around $120. You can also get custom bleaching tray systems from your dentist, but they will cost more like $300 to $600. You inject a bleaching gel into the front of the trays which contains 16 to 22 percent carbamide peroxide and wear the trays for one hour a day for one to two weeks.
