Smile! Show me those pearly blue-green teeth. |
Next time you find yourself at your local drug store or bodega, hum along to the soft rock and stroll over to the dental aisle. There you will find bottles of mouthwash that boast bright blue, green and red colors that would cause a package of Starburst to blush. These colorful mouthwash bottles sit right above numerous pastes, gels and trays that promise to whiten your teeth. Odd, isn't it? Every person wants whiter teeth...yet most dental mouthwashes contain Red #40 food coloring.
