Sensitive toothpaste works by using special ingredients that can help to alleviate the discomfort associated with tooth sensitivity. These toothpastes contain active ingredients that can help to block the pathways that allow sensations such as hot or cold temperatures to reach the nerves inside the tooth.
The most common active ingredients in sensitive toothpaste are potassium nitrate and/or strontium chloride. Potassium nitrate is thought to work by blocking the tiny tubules in the dentin, the layer of the tooth beneath the enamel, which contain nerve endings. Strontium chloride, on the other hand, is believed to work by forming a protective layer over the exposed dentin, which helps to prevent the transmission of painful stimuli.
In addition to these active ingredients, sensitive toothpaste may also contain fluoride, which can help to strengthen the tooth enamel and reduce the risk of decay, and desensitizing agents such as benzocaine or menthol, which can provide temporary relief from sensitivity.
To use sensitive toothpaste, you simply brush your teeth with it twice a day, just like you would with regular toothpaste. Over time, the active ingredients in the toothpaste can help to reduce tooth sensitivity and improve overall oral health. However, if you have persistent or severe tooth sensitivity, it is important to consult with a dentist to rule out any underlying dental problems that may require more specialized treatment.
