Q: WHAT IS TARTAR AND WHY IS IT BAD FOR YOU?
A:Tartar (also known as dental calculus) is hardened bacteria that occurs when dental plaque gets stuck on your teeth and comes in contact with your saliva. So what is tartar? There are two types and one of them is more harmful than the other:
1. Tartar along the gum line
This type is called supragingival (above the gum) tartar and is often formed on the lingual surface of the mandibular anterior teeth or on the outside of the large teeth in the upper jaw.
2. Tartar between the teeth and the gingiva
The other, and more harmful, type of tartar is called subgingival (below the gum) tartar. It thrives within the sulcus (gum pockets) between the teeth and the gingiva.
