Which type of dental treatment is primarily focused on restoration?

Restorative dental treatment is specifically aimed at repairing and restoring the function of teeth that have been damaged by decay, injury, or other issues. This type of treatment includes procedures such as fillings, crowns, bridges, and dentures. The primary goal of restorative dentistry is to restore the natural function of the teeth, as well as to improve aesthetics when necessary.

When considering the other options, preventive dental treatment focuses on avoiding dental issues before they start, often involving cleanings and fluoride treatments. Orthodontics is concerned with the alignment of teeth and correcting bite issues, which does not primarily involve restoration. Endodontics deals specifically with the dental pulp and root tissues, usually requiring procedures like root canal therapy, which, while they may restore function, don't encompass the broader category of restorative work that also includes non-pulp related restorations.
