An increased tooth sensitivity is usually detected when eaten cold, hot, sour or sweet drinks or food. Stripping of the tooth necks (between the crown and root of the tooth) can be also caused by incipient periodontitis. The most common cause of sensitive teeth is actually a mechanical damage caused by poor dental cleaning technique, unsuitable tools (too hard brush), a lot of pressure on the toothbrush or the inconvenient tension of a mucous membranes and a frenulum in the mouth. Increased tooth sensitivity and gum also may indicate a dental caries. The increased sensitivity can also be caused by an old and inadequate fillings, a cracks or a holes on the teeth, or bruxism (clenching and gnashing of teeth).
At increased tooth sensitivity is often neglected oral hygiene because of pain during mechanical brushing. Permanent presence of plaque containing bacteria on the exposed crowns leads to a gums sensitivity or gingivitis. Gingivitis is easily recognizable by several symptoms, such as bleeding gums, red, shiny and swollen gums, bad taste and bad breath, itchy.
While a baring of the dental neck reveal the dentinal tubules (canals), which lead from the surface of the tooth to the dental pulp, where is interwoven a network of nerve fibers. In the initial stage the tooth sensitivity can be reduced without “interference” by the dentist. Dental canals are sealed by a calcium compounds from a saliva and thanks to suitable toothpastes designed for tooth sensitivity. It is appropriate, therefore, to see a doctor or dental hygienist to remove the plaque, make a correct choice of dental appliances and briefing proper tooth brushing techniques. If the sensitivity is still increased it is possible to put a special coating on the bared dental necks. In more severe cases we may overlap the bared neck by the “white” fillings in the doctor’s office.
