What is it?
Tooth sensitivity affects many people. It often occurs from eating or drinking something hot, cold, sweet or sour. Under normal conditions, that is in the dentin inside the tooth (the layer surrounding the nerve) is covered on the top (crown) for the glaze and the gums surrounding the teeth. Eventually, the glaze can be losing thickness, causing less protects the tooth. Also gums may pull over time, exposing the dentin of the root surface previously covered.
Dentine contains a large number of pores or tubules which are from outside of the tooth to the nerve center. When the dentin is exposed, these tubules are stimulated by temperature changes or by certain foods.
What causes it?
- Dentin exposure may be due to several factors. Some of the most common are:
- The withdrawal of the gums due to age or improper brushing technique
- Acidic beverages (such as soda) that erode enamel and exposed dentin
- Teeth grinding, which can become sensitive to all or most of the teeth or molars
- Brushing with a paste too abrasive teeth incorrectly and / or more than three times a day, may cause enamel loss
- Gum disease, which can cause it to retract
- A small break or crack can expose the dentin
Furthermore, there are some which cause dental sensitivity. It is known that treatments like tooth whitening, oral cleaning, placement of orthodontic appliances or fillings, cause tooth sensitivity during or after the procedure.
