The sensitive teeth, or tooth sensitivity is a more common problem than we think and, moreover, can be extremely annoying, preventing enjoy some pleasures like taking a sip of a cold drink or a bite of hot food. This simple gesture can cause discomfort and pain in the teeth. Why it occurs? What can we do about it?
Sensitive teeth causes
The term of sensitive teeth refers to the dental hypersensitivity, an annoyance that can vary in intensity and is caused by heat and cold (hot dishes and cold drinks). Both excess heat and cold directly attack the teeth and in particular, to dentine, tissue located between the top enamel of the tooth and the pulp. The dentine forms the greater part of the tooth and is responsible to protect the pulp.
Dentine consists of so-called microtubules, which contain essential cells for its maintenance, the extracellular fluid that is essential for the transmission of stimuli to nerve receptors that are found in the tooth.
The extracellular fluid activates the microtubules and triggers the annoying reaction as a result of thermal or tactile stimulation from the outside.
Heat and cold are responsible for sensitive teeth, but the causes are different. Sensitive teeth tend to be the result, in the majority of cases, the removal or loss of enamel which covers the crown. The discomfort will appear when taken acidic foods, carbonated beverages, citrus, vinegar and wine. Other risk factors are insufficient dental hygiene, presence of bacterial plaque, using unsuitable brushes for oral hygiene (e.g. hard-bristled toothbrush) or too abrasive toothpaste.
For the tooth sensitivity, the first thing we must do is to limit the consumption of alcoholic beverages and soft drinks, as well as those rich in caffeine and too acidic, as they may have a corrosive harmful effect to the teeth. It is also important to avoid too bitter foods.
For its part, between the natural allies to relieve the discomfort we may have recourse to the mallow. Simply prepare an infusion of the plant and use it as a mouthwash twice a day. Also useful is the tea tree oil, the calendula and aloe vera, which gel is good for the health of the gums.
