Try flossing daily, and brush 3 times a day, don't forget to clean your tongue it can hold a lot of bacteria and cause halitosis.
Reply:A quality electric toothbrush like those made by Braun/OralB or Sonic-Care is very effective at controlling the yellow plaque build-up. They are expensive ($50-$100) but well made and worth it!





You must use it by "gliding" slowly through your mouth, placing the brush head half on your teeth and half on your gums for at least two minutes. Don't push hard! Replace the brush head every 3 months.





Your professional cleanings (scalings) are still needed every 3-6 months, but will become easier due to less build-up.
