What term describes a tooth covering that encases the visible portion of a tooth?

• A. Alginate
• B. Crown
• C. Desensitizer
• D. Implant

Answer: (B)

The term is crown. A crown is a cap that fits over the prepared portion of a tooth, encasing all the visible surfaces above the gumline to restore shape, strength, and function after decay, fracture, or root canal treatment. It can be made from porcelain, metal, or a combination and is cemented in place. Alginate is an impression material used to make a mold of the teeth, not a covering. A desensitizer reduces sensitivity, and an implant is a replacement tooth root placed in the jawbone (a crown may sit atop an implant, but the implant itself is not the covering).
