2. What part of the tooth is the hardest part of the entire body?

Dentin

Pulp

Enamel

Gingiva

Enamel is the hardest part of the entire body because it is the outermost layer of the tooth and is composed of a dense mineral called hydroxyapatite. Enamel is highly mineralized and serves to protect the underlying dentin and pulp from damage caused by chewing and other forces. It is also resistant to acid and bacteria, which helps prevent tooth decay.

3. What plastic mouthpiece can provide protection from teeth grinding and injury during sports?

Bridges

Mouth Guard

Dental Sealants

Braces

A mouth guard is a plastic mouthpiece that can protect teeth from grinding and injury during sports. It acts as a cushion between the upper and lower teeth, absorbing the impact of any force or trauma that may occur during physical activity. This helps prevent teeth from chipping, breaking, or getting knocked out. Mouth guards are commonly used in contact sports such as football, boxing, and hockey, but they can also be beneficial for any sport that involves physical contact or the potential for dental injury.

Humans have four types of teeth: incisors, canines, premolars, and molars. Incisors are used for cutting and biting, canines are used for tearing and grasping, premolars are used for crushing and grinding, and molars are used for grinding and chewing.

5. What is the artificial device that can be used to place the teeth under tension for a long period of time?

Veneers

Dentures

Bridges

Braces

Braces are an artificial device that can be used to place the teeth under tension for a long period of time. They consist of brackets, wires, and bands that are attached to the teeth and apply gentle pressure to gradually move them into the desired position. By exerting constant tension, braces can effectively correct misaligned teeth and improve the overall alignment of the jaw. Veneers, dentures, and bridges are not designed to place teeth under tension for an extended period, making braces the correct answer.

Tooth decay is a common dental problem that can cause pain, sensitivity, and the need for dental treatments such as fillings or root canals.
