Crest Gum and Sensitivity TV Commercial, 'Treat at the Source'

While enjoying a smoothie with her daughter, a woman grimaces in pain as the cold beverage makes contact with her sensitive teeth. A dentist informs her that the sensitivity she's experiencing in her mouth starts at the gumline and needs to be treated at the source. After the woman uses Crest's Gum and Sensitivity toothpaste, her animated winces are no longer from sensitivity. Just brain freeze!
