Cavity prevalence is quite high, especially in children who haven't developed good oral hygiene habits and consume a lot of sweets, making them prone to cavities. Early detection is thus very important. Early symptoms of cavities are not obvious, but with careful observation, one can notice parts of the teeth turning black. This is due to bacterial erosion and damage to the teeth. Damage occurs to the enamel and dentin of the teeth. If this continues to develop, it can lead to damage to the dental pulp, resulting in pulpitis. Therefore, when you notice your teeth turning black, it is crucial to seek timely treatment to prevent the progression to pulpitis.
