How does Colgate Sensitive Instant Relief Repair & Gentle Whitening work?

Most other sensitive toothpastes primarily numb the pain. Colgate Sensitive Instant Relief Whitening works by plugging the channels that lead to sensitive tooth nerves, to block the pain.
With regular use, it builds a long-lasting protective barrier that acts like a seal against sensitivity. Its low abrasive formula gently and effectively removes stains, helping to restore the natural whiteness of your teeth.

• Clinically proven instant and lasting relief up to 8 weeks.
• Blocks the pain of sensitive teeth.
• Gentle whitening formula.
• Gently and effectively removes stains.
• Helps restore natural whiteness of teeth.

Directions for Use:
For instant relief, apply directly to the sensitive tooth with finger tip and massage gently for 1 minute, up to twice a day and for children 6-12 years once a week or less frequently.
For lasting relief, apply to a gentle toothbrush making sure to brush all sensitive areas of teeth. Brush twice daily.

Cautions:

• Sensitive teeth may indicate an underlying problem that may need prompt care by a dentist if pain persists.
• Children of 6 years and younger: use a pea sized amount for supervised brushing to minimise swallowing.
• In case of intake of fluoride from other sources consult a dentist or doctor.
• For best performance, keep cap closed when not in use.
