ANATOMY

Detailed explanation-1: -The last stage is advanced periodontitis; this is when there is no more bone or tissue to support the tooth and root. Here you are at a very high risk for tooth loss and heart disease. Cavities: they form when bacteria infection sits for too long and causes tooth decay.

Detailed explanation-2: -Attrition is tooth wear caused by other teeth. When you clench or grind your teeth (bruxism) your teeth will begin to wear down. Imagine grinding two sticks against each other. With enough friction, the sticks will begin to wear down.

Detailed explanation-3: -Cap Stage During this stage, cells begin to shape the outside layer of the tooth, forming a cap that sits on the rest of the tooth bud. This cap is called the enamel organ because it will later form the cells that produce enamel.

Detailed explanation-4: -Attrition refers to tooth against tooth friction-like grinding. Erosion is chemical wear on our teeth from either the acids in our diet, or stomach acid. Abrasion is wear from a foreign element against tooth-often times toothbrushes and toothpaste.
