How Ingredients in Sensodyne Toothpaste Work

Sensodyne is a toothpaste recommended for people suffering with tooth sensitivity. Nearly 1 in every 5 adults in the United States suffers from this dental problem. They belong mostly to the age group of 25-50 years. This article tries to understand about the ingredients in Sensodyne Toothpaste and their working.

What is Tooth Sensitivity:

The root of our tooth is called the dentin. It provides strength to the tooth. The Dentin is made of very small holes called the tubules. They are connected to the nerves in deep interiors of the tooth. The tubules are covered and protected by a substance called Cementum. When this protective layer of Cementum is removed, the tubules of the dentin get exposed.

In such a condition, when a person eats any sweet, hot or cold food item, the sensations reach the sensitive nerves through the exposed tubules of the dentin. This causes pain which is the primary complaint of tooth sensitivity.

Ingredients in Sensodyne Toothpaste:

The chemical components present in the tooth which treats tooth sensitivity are as follows:

  • Potassium Nitrate
  • Sodium Fluoride
  • Strontium Chloride
  • Strontium Acetate
  • Potassium Chloride

How Ingredients in Sensodyne Toothpaste Treat Tooth Sensitivity:

The important component in the toothpaste are Potassium Nitrate and Sodium Fluoride. These chemical components are the sources which provide the Potassium and Fluoride particles. When the toothpaste is applied over the teeth, Potassium and Fluoride particles enter in the exposed tubules of the dentin. They reach the pain causing nerves and make them neutral. In this way, signals of pain sent by these nerves to the brain are stopped providing relief to the patient. Potassium Chloride helps in calming the nerves further. The components Strontium Chloride and Strontium Acetate create an artificial protection layer for the tubules of the dentin.
