Suffering from tooth sensitivity is, for some, simply unbearable. It is a sharp pain caused by wear of the tooth surface or gum tissue (gums). So, eating hot, cold, sweet or acidic can become a real torture.
It is estimated that between 9 and 30 percent of the adult population suffers from hypersensitivity, which increases to 40, is most common in people between 20 and 30 years of both sexes.
In medical terms, Dr. Laura Santamarina, chairman of the Department of Communications of Argentina Dental Association, explains that tooth structure consists of an inert surface-outer-enamel, a prominent international dentin surface (which has extensions nerve) – , and the pulp, which contains nerves, arteries and veins. “The tooth sensitivity is the overreaction to a harmless sensory stimulus and arises from exposed dentin by a reaction to chemical stimuli, thermal or tactile. This pain is caused and never always spontaneous, and usually coincides with the duration of the stimulus: if this is removed from the tooth sensitive area, the pain disappears, “says the dentist. The pain should not last more than 3-5 seconds.
What stimuli respond?
Without dental disorder, one of the most frequent causes of their occurrence is related to the loss of enamel by bruxism, abrasion or erosion, and in patients suffering from disorders of the digestive tract or recurrent vomiting.
“The other relates to cause retraction caused by periodontal disease, improper brushing and trauma. There are also dental treatments may initiate or promote the development of symptoms such as restorations, prostheses or bleaching, “says the specialist.
The stimuli are normally thermal changes, cold, heat, either dry (air) or in a liquid (drink) or solids (food).
It can also cause pain sweetened beverage intake, acid and / or low pH and consumption of citrus.
Treatment
Dr. Santamarina says: “This problem must be evaluated by the dentist according to clinical examination, dental history and habits of the patient. There are treatments that are performed in the office with desensitizing chemicals in those with healthy teeth and restorations, in case of loss of tooth structure. Outpatient therapeutic also home to reinforce the patient’s dental treatment. ”
Among the solutions we mention household desensitizing toothpastes, gels and mouthwashes with various chemical formulas.
Prevention
Use a soft brush and change it every two months, learn proper brushing techniques (support the brush at 45 ° and move in a circular or vertical (not horizontal because it fosters enamel damage).
If tooth sensitivity, discomfort should disappear about two weeks. Otherwise, only a specialist can help.
