Stages of Dental Caries-Tooth Decay- Signs and Symptoms- Neglect at your own cost


Tooth decay does not happen overnight, Its progress is usually slow to give both the patient and dentist adequate time to manage the same.

Stage One: White Spots

The first stage of tooth decay involves the appearance of yellowish spots or chalky white areas on the surface of tooth due to the loss of calcium.

Such tooth decay is still reversible, with proper treatment.


ØChalky white areas or yellowish spots, occasionally food Impaction- Food getting stuck frequently between teeth

Dentist Role and Treatment

Ø The decaying tooth can be saved by the application of fluoride and certain minerals present in the saliva. During the initial stages of tooth decay, the condition can be easily countered.

Stage Two: Enamel Decay
