Why is Winston given regular meals, clothes, and dental work?

O'Brien continues to be Winston's savior by providing him with basic comforts such as a mattress and a pillow, and gain back his strength. In this process, Winston begins to fully accept O'Brien's version of the world. Without the Party, there is nothing. Here, we see the effectiveness of the combination of O'Brien's physical and psychological torture. Winston, a lone man, has no hope for successfully rebuffing these invasions into his body and mind. He is overcome through force and power. Knowing he has been beaten, Winston still wonders when he will be finally be killed, when the Party will finally decide his life is over.
