Crest pro health sensi stop tooth sensitivity relief strips
Sensitivity products may ease discomfort, but persistent sensitivity can indicate decay, erosion, cracks, or exposed roots.
The short answer
Tooth sensitivity is a short, sharp response when exposed dentine reacts to cold, heat, sweetness, touch, or air. Whitening strips and other peroxide products can temporarily irritate the tooth surface or gum, but they do not treat decay or a crack.
How should you respond to pain from whitening products?
Stop a whitening product if it causes marked pain or gum irritation, use a soft brush, and choose toothpaste formulated for sensitivity. Do not place strips over damaged enamel, untreated cavities, loose restorations, or inflamed gums without professional advice.
When should a dentist assess sensitivity after whitening?
See a dentist when sensitivity is new, localized, worsening, spontaneous, or present after the trigger is gone. Urgent assessment is appropriate with swelling, fever, a fractured tooth, severe pain, or difficulty opening the mouth.
What cause of sensitivity should your dentist investigate?
Ask whether the sensitivity comes from exposed dentine, decay, a crack, gum recession, or pulp inflammation. Ask which product ingredients and application time suit your teeth and whether whitening should wait until treatment is complete.
Frequently asked questions
Should I keep using sensitivity strips?
Pause the product if pain or gum irritation is significant, and have the cause of sensitivity checked before trying another whitening product.
What should I record before the visit?
Record the trigger, location, duration, severity, and any gum recession, bleeding, or recent whitening.
