A reductive composition, suitable for the dental industry, which utilizes sodium dithionite may be provided when it is combined with either polyethyloxazoline or polyvinylpyrrolidone. Other dithionite molecules, such as potassium dithionite, may be used. Likewise, the methods described herein may be applied to other reductive agents.

A reductive composition, suitable for the dental industry, which utilizes sodium dithionite may be provided when it is combined with a sweetener selected from the salts of acesulfame. Sodium and potassium acesulfame show effective resistance to the reductive capacity of sodium dithionite. Other dithionite molecules, such as potassium dithionite, may be used.

A reductive composition, suitable for the dental industry, which utilizes a salt of dithionite may be provided to create an alkaline tooth whitening compound. Either Sodium or potassium dithionite may be used with marked effectiveness. A simple buffered solution of dithionite and water may whiten teeth in an alkaline environment that lessens damage to tooth ename.
