Yellow portions on teeth are hardened food deposits called calculus which you can not remove by simple brushing. The black areas can be due to cavity or caries. In bangalore if you can visit dental colleges like GDC, RV dendal college, vs dental college etc your both problem will be resolved at very cheaper rate. Say within 2000 rupees. THANK YOU.
Hello Mr. lybrate-user the yellowish black stains present on your teeth are nothing but plaque and calculus deposits on the teeth. By simple procedure of ultra sonic cleaning and polishing of teeth your problem can be fixed. But remember that this procedure has to be repeated every 6 to 8 months to keep the plaque and calculus away.
You need to get scaling done by the dentist as the plaque cannot be removed manually by any toothbrush.
