Now that summer comes, we all want to drink something cold, but many people are deprived of ice cream or a refreshing drink because they feel a painful sensation whenever you take something fresh.

It manifests as a localized sensation of pain (mild or sharp), especially when drink hot, cold, sweet or sour, this is what is called dentin hypersensitivity. This is a relatively common problem in dental practice consultation, is due to some disease, vigorous brushing, etc.., Gums recede exposing the cement and / or dentine (inner layer of the tooth) and teeth become more sensitive.

Thus, the usual lack of protection of the dentin allows different stimuli – such as heat, cold, or acidic foods or sweet-stimulate nerve endings inside the tooth and cause the sensation of pain. Why does this happen? The situation has many causes, such as wear of tooth enamel, periodontal diseases (such as gingivitis) that produce a receding gums, and even tooth whitening treatment.
