Why bleaching action of SO2 is not permanent?
The bleaching action of sulfur dioxide (SO2) is not permanent because it is a reversible process. SO2 can react with oxygen in the air or other chemicals to form compounds that are not colorless, leading to the loss of its bleaching effect. Additionally, SO2 can evaporate over time, reducing its concentration and effectiveness as a bleaching agent.

The Facts on Teeth Bleaching?
The shiny teeth you had as a kid don’t last, unless you’re one of a lucky few who have naturally white teeth. The rest of us can look forward to our tooth enamel becoming darker and more discolored over time as a result of staining and environmental contamination. But today there are a lot of opportunities to return your teeth to their original sparkling state through bleaching. The term teeth bleaching embraces a variety of methods, some of which you can do yourself at home and some of which are done by your dentist in his or her office. Home bleaching usually involves either applying chemically treated strips to your teeth, or fitting trays filled with bleaching gel over your teeth. Your dentist will be able to help make trays that match the shape of your teeth exactly. Off-the-shelf trays are less effective since they do not hold the gel against your teeth as closely. It can take a week or two before you see any benefit from these methods. Having your teeth bleached by a dentist will produce quicker and more dramatic results. Your dentist will paint your teeth with a bleaching solution and then apply a strong light to accelerate the bleaching process. This can be done in a single office visit. Some dentists also use teeth-bleaching gel, although in a higher concentration than you can buy over the counter. Bleaching your teeth is generally a safe process, although it can lead to some discoloration of the tissues of your mouth and increased sensitivity. While there was once some fear that bleaching could damage tooth enamel, studies have shown that this is not so. However, if you already have sensitive teeth, receding gums, or other gum problems, talk to your dentist before you use any bleaching method. Not everyone will benefit from teeth bleaching, and the new whiteness will wear off eventually -- faster if you smoke or consume strong staining substances such as coffee or red wine. Bleached teeth generally return to their normal appearance in a month or two after treatment.
