hello, yellow teeth could be because deposits on you teeth or food lodged in your gums. visit a dentist and get a scaling and polishing done. brush twice daily, maintain proper brushing technique, floss regularly and rinse after every meal. visit dentist every 6 months. The cost can range from Rs.500-2000/-.

You should start brushing thrice daily after meals,,get scaling done from a dentist and I cannot tell how much does it cost.

Hello there. I can understand your concern. For that first you have to visit a dentist in person so that he can examine you and then he will tell you what exactly needs to be done. The cost varies from dentist to dentist and place to place. Usually in govt hospitals they would do it for even free. Best regards. Dr. Anil Kumar Jain. Bangalore.
