My left molar has started to decay. Its paining when I am having cold water. The inner part has turned black. Please help.

Decayed tooth has to be filled from dentist. If decay is deep you have to go for root canal treatment. Visit to a dentist for xray and proper treatment.

Kindly consult a dentist in person for further suggestion. We need more investigations with clinical examination to decide upon treatment. You may need root canal treatment. Until then apply clove oil on the decayed tooth. Rinse frequently with mouth wash. Advise c. Amox 500mg 1-1-1, thrice, t. Metrogyl 400mg 1-1-1, thrice, t. Imol 1-1-1, thrice (contraindicated in conditions with gastric ulcer, asthma, wheezing, and allergy), and c. Becosules 1-0-0 once, all for 3 days only. Advance procedures can be done with laser. You may consult me in person. Dental tips: - visit a dentist every six months for cleaning and a thorough dental check-up. Limit sugary food to avoid tooth decay.
