Routine cleaning rids the mouth of plaque, which contains the harmful bacteria, and is one of the most critical steps you can take to preserve the health of your teeth and gums.
However, over time the dental plaque will solidify, and small deposits will accumulate around your teeth and gums. These hardened deposits cannot be removed by your toothbrush or floss, and must be removed by your dentist. This process is usually referred to as a scale & polish.
