Final answer:
Restorative dental treatment covers filling cavities, root canal treatment, and dental implants, which are procedures that restore the function and integrity of teeth. Teeth whitening is not usually included as it is cosmetic. The correct option is 1.
Step-by-step explanation:
Restorative dental treatment encompasses various procedures that aim to repair and restore the function and integrity of teeth. Restorative dental treatment covers a range of services including filling cavities, root canal treatment, and dental implants. Specifically, these treatments address the following issues:
- Filling cavities involves removing decayed tooth material and filling the resulting space with a material such as dental amalgam or composite resin to restore the tooth's shape and function.
- Root canal treatment is necessary when the pulp of a tooth becomes infected or inflamed, requiring the removal of the damaged tissue and sealing of the tooth to prevent further infection.
- Dental implants are used to replace missing teeth with artificial structures that mimic the appearance and function of natural teeth.
Teeth whitening, on the other hand, is considered a cosmetic procedure and is not typically included in restorative dental treatments as it does not repair or restore tooth structure or function.
