Is sensitive toothpaste
different from a normal toothpaste?

Toothpaste is a paste or gel used along with a toothbrush to maintain oral hygiene. It aids in removing dental plaque and food from the teeth, assists in suppressing halitosis (bad breath) and delivers active ingredients (most commonly fluoride) to help prevent tooth decay and gum disease.

A desensitizing / sensitive toothpaste is a toothpaste that is specially formulated to treat or soothe sensitive teeth immediately, or in the long term. Without any invasive procedures or expensive treatments, sensitive toothpaste can reduce the symptoms of tooth sensitivity during your regular tooth-brushing regimen. Sensitive toothpaste contains ingredients such as potassium nitrate that block the pathway to pain receptors, strontium acetate / chloride that block the inner exposed part of the tooth and ease tooth sensitivity. With daily use, these ingredients can even help curb tooth sensitivity in the long term.

A normal flouridated toothpaste with around 1000-1500ppm (parts per million) of fluoride is recommended for regular daily toothbrushing, whereas a sensitive/desensitizing toothpaste is recommended for those with sensitive teeth.
