Final answer:
The most convenient home bleaching method for tooth discoloration is plastic trays with an oxidizing agent.
Step-by-step explanation:
The most convenient home bleaching method for a patient with tooth discoloration is plastic trays with an oxidizing agent. This method involves using custom-made trays that fit over the teeth and are filled with an oxidizing gel. The trays are worn for a specified amount of time each day, usually for a few hours or overnight.
The oxidizing agent in the gel breaks down the stains on the tooth surface, resulting in a whiter appearance. This method is convenient because it can be done at home and does not require frequent visits to the dentist.
