Many people suffer ongoing and acute discomfort in teeth when performing common daily activities, such as drinking a cup of hot tea or coffee, eat ice cream or brushing teeth. That may be due to tooth sensitivity, one of the most common oral diseases, the suffering about 20% of adults, especially between 25 and 45.
Although all teeth are susceptible to hypersensitivity, the highest incidence occurs in the premolars. These are the ones that tend to be brushed harder, and that can damage the enamel and leave the tooth exposed and susceptible to external stimuli.

What is tooth sensitivity?
Dental hypersensitivity is a painful, sharp and brief that responds to different external stimuli. These stimuli can be thermal (hot food or cold drinks), chemical (acid or sweet substances) or mechanical (brushing, etc..).
Why dental pain occurs?
This sensation occurs when the enamel and cementum of the teeth wear out, leaving the inside of the tooth - dentin and niervos - exposed to external stimuli. These stimuli can cause irritation of the nerves, causing acute pain sensation.
What are the main causes of tooth sensitivity?
Many daily activities can lead to tooth wear, and generate a painful and acute. Here we inform the main causes of dental hypersensitivity:
Improper Brushing: Brushing teeth with horizontal movements and force can damage the gums and wear away the enamel. Thus, the niervos exposed. Always do a circular and vertical and use a soft bristle brush.
Foods with acids: high intake of acidic foods like citrus fruits can cause erosion and dissolution of the tooth surface with the consequent exposure of dentin.
Teeth Whitening: this treatment can cause tooth sensitivity for a few weeks because it leaves the outer layers of the tooth exposed.
Gum disease: inflammation in the gum tissue can destroy that protect the teeth, leaving exposed to the external stimuli.
