Hello , Can you share clinical photograph of the teeth ?

Attach pic of teeth, which will help to achieve a confirmatory diagnosis. Are there high iron level in drinking water or local water supply, that can cause black stain. Or may be initiation of decay in teeth.

Hello Dear Hope I can decrease your discomfort See black spots are usually due to dental caries or stains I suggest you to please share pic for confirmation of the lesion

Black spots means dental caries. Caries is an irreversible process. You should get the treatment done as early as possible irrespective of pain. Treatment will be restoration or root canal treatment depending on the extent of cavity.

Black spots may be a sign of dental caries...If you are not experiencing any pain or sensitivity then the caries is at an early stage and can be treated simply by filling..

Dear Patient Good oral hygiene is the first step for white and healthy teeth. If you are already brushing twice a day, please share more information on these spots. Since how many days did you notice them? First we need to find out what kind of spots are these . Based on that the treatment can be decided.  If you have not gotten  your  Dental scaling done regularly , that can also be the reason . Please share more information on your health.Do you smoke, are you taking any medicines,if yes since when etc. Dr Divya
