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.

Teeth bleaching is the only option that does not involve a treatment for improving the health or function of teeth. Floosing teeth helps in removing food particles and plaque from between the teeth. Rinsing teeth with mouthwash helps in maintaining oral hygiene and preventing gum diseases. Teeth whitening is a cosmetic procedure that helps in removing stains and discoloration from the teeth. However, teeth bleaching is solely focused on changing the color of the teeth for aesthetic purposes, rather than addressing any dental issues.

- A.
  
  Veneers
- B.
  
  Dentures

Correct Answer
D. Braces

Explanation
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.

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.
