WHAT IS TOOTH SENSITIVITY?
WHAT IS TOOTH SENSITIVITY?
The outside of our teeth is called enamel, which protects our teeth from hot or cold stimulus. With the loss of this outer layer of our teeth a second layer which is called dentin rises to the surface and, we feel a short but sharp pain when we encounter something hot, cold, chemical or tactual stimulus. This situation is described as dentin sensitivity.
Dentin sensitivity is mostly caused by loss of enamel and receding gums. People who are mostly exposed to this are mostly between 20-50 years old, especially the ones between 30-40.
Dentin sensitivity is seen in 1 person out of 7. It is seen less in elders compared to others.
WHAT ARE THE REASONS OF DENTAL SENSITIVITY?
Brushing : Inadequate toohtbrushing causes dental plate and when the plates are not cleaned, they cause gum diseases. On the other hand, too much use of brush and being obsessed with toothbrushing may also cause receding gums.
Gum diseases: Inadequate mouth care causes some advanced gum diseases. Further phases of diseases cause tissue destruction and this may lead to teeth loss even if the teeth are healthy.
Dental Treatments: After dental cleaning is made, dentin tubules migh be exposed and cause sensitivity.
Diet: Acidic beverage, chemical products, medication, pyrosis and gastric asid caused by throwing up causes enamel to dissolve because of low Ph nutrition.
Incompatible restoration and mouth closing disorder.
Physiological causes: Exposed tooth root caused by aging, uncontact teeth may cause dental sensitivity.
Not all of the exposed dentin are necessarily sensitive. Protective layers that formed around dentin, dentins being refreshed naturally and some minerals provided by saliva may occlude tubules and prevent sensitivity.
WHAT CAN BE DONE TO PREVENT DENTAL SENSITIVITY?
Adequate plate control is the most important factor to reduce or cure dentin sensitivity. However, sensitivity may oppose to plate control.
Superficial floride treatments, floride contained mouthwash, dentin bonding agents are the most frequent treatmens. Altough these treatmens are successfull on some levels, the most effective one is dentin bonding agents. If these protective treatmens fail, more advanced treatments might be necessary.
Dentin sensitivity eliminators that can be used at home are; different mineral salt included products, toothpaste that contain floride, mouthwash, and gel.
Florides, mineral contained agents, laser and dentin bonding that are applied by a doctor in a clinic are noninvasive methods.
The last invasive methods are composite restorations, protective treatments, nerve removal and periodental surgery.
