Description and useReceding gums and damage to your enamel can expose thousands of microscopic channels which lead to your tooth's nerve centre. When your teeth make contact with something hot, cold or sweet, sensations are carried down these channels directly to the nerves, causing pain. Colgate Sensitive Pro-Relief 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.DosageApply directly to the sensitive tooth with finger tip and gently massage for 1 minute, once a week or less frequently.
