Colgate Sensitive Pro-Relief Original works by plugging the channels to block the tooth sensitivity. Most other sensitive toothpastes primarily numb sensitivity. With regular use, it builds a long-lasting protective barrier that acts like a seal against sensitivity. An exclusive Pro-Argin™ formula with a technology that dental professionals use to provide instant and lasting sensitivity relief.

Directions for Use:

• For instant relief, apply directly to the sensitive tooth with finger tip, and massage gently for 1 minute, once a week or less frequently. 
• For lasting relief, apply to a gentle toothbrush making sure to brush all sensitive areas of the teeth. 
• Brush twice daily. 
• Children of 6 years and younger: Use a pea-sized amount for supervised brushing to minimize swallowing. 
• For best performance, keep cap closed when not in use.

Cautions:

• Sensitive teeth may indicate an underlying problem that may need prompt care by a dentist if sensitivity persists. 
• In case of intake of fluoride from other sources, consult a dentist or doctor.
