Colgate has launched an improved super premium toothpaste called Colgate Sensitive Pro-Relief to increase their market share in the sensitive toothpaste segment. The toothpaste uses Pro-Argin technology containing arginine and calcium carbonate that is clinically proven to provide instant relief from tooth sensitivity with one direct application to the sensitive tooth. It also provides long-lasting relief from sensitivity with regular twice daily brushing by desensitizing nerves and building a protective shield on the teeth. Colgate aims to change perceptions that sensitive teeth issues can be treated without visiting the dentist through regular use of their new toothpaste.
