Answer (1)
The part of the tooth that is visible when we open our mouths is called the "crown." The crown is the outermost part of the tooth and is covered with enamel, which is the hardest substance in the human body. The crown is what we see above the gums.
In each jaw (upper and lower), adults typically have 12 molars. This includes 6 in the upper jaw and 6 in the lower jaw. Molars are the back teeth that are used primarily for grinding and chewing food.
The yellow sticky layer present on teeth is called "plaque." Plaque is a soft, sticky film that forms on your teeth when bacteria in your mouth mix with sugary or starchy foods. It can lead to cavities and gum disease if not removed regularly by brushing and flossing.
The type of teeth used for grinding are the "molars." As mentioned earlier, molars are located at the back of the mouth. They have a large, flat surface ideal for breaking down food into smaller, digestible pieces.
