Chances are that it may be a non carious lesion called Cervical Abrasion.
Cervical abrasions or Non carious tooth lesions are the result of Vigorous improper tooth brushing with a very hard tooth brush or abrasive dentifrices.
Such lesions typically occur at the neck of the teeth and appear to cause gingival/gum recession. The receding gums expose the root surface further and lead to development of sensitivity .
(Initially the sensitivity is mild )
This progresses to expose the pulp and may require root canal treatment. In many cases if the lesion is spotted early a simple filling can solve the problem. At times a minor gum corrective procedures ( Plastic periodontal surgery ) can completely cover the defect and provide aesthetic results.
If allowed to progress unchecked the lesion can become un restorable or irreparable.
In our following posts we will share with you the different methods by which such a lesion can be treated.
Until then brush well.
