A very common phenomenon is that of dentinal hypersensitivity, a dental condition manifested by the perception of discomfort or pain caused by the stimuli of heat, cold, sweet and acid, very vigorous tooth brushing or contact with metal objects. Generally, these symptoms are a consequence of the uncovering of the collars of the teeth due to the retraction of the gingiva.
The causes include several factors:
- the age
- the accumulation of tartar in the gum pockets
- enamel wear due to the use of too hard toothbrushes or very abrasive toothpastes
- very acidic pH of the mouth
The tooth surface that emerges from the exposed collar is not as protected as the surface normally covered by enamel and is therefore much more sensitive to external stimuli.
If the problem persists, seek advice from your dentist or dental hygienist.
