Dear Lybrate user, Brushing your teeth twice daily wisely and reaching every corner (even the inside of the teeth) is the best that you can do to remove plaque. You should use floss to be able to clean in between your teeth and a tongue cleaner to keep your tongue clean and free of plaque. You should visit a dentist
if you have hard deposits in the inside of your teeth that cannot be removed with toothbrush. Scaling and polishing will make your teeth shine!
