Is Listerine good for your teeth?

Listerine Mouthwash causes Yellow Teeth?

• Can Listerine's mouthwash, which is yellow colored, make my teeth yellow? I usually resort to buying other brands that aren't colored yellow but find that those brands dont have that feeling where i know it is working.

• Answer:

  I don't know anyone who uses Listerine that regularly to determine if their teeth have become yellowed from using it, but there is a home remedy available somewhere (sorry, I don't know where) which uses clear liquid products which would give you the sensation you describe. Saltwater is a time-honored mouthwash and cleanser, also. It would be interesting to know if there are any studies done on the long-term effects of each of these types of ingredients.
