What is a primary indication for using a dental crown?

The primary indication for using a dental crown is to provide strength and protection for severely decayed or fractured teeth. Crowns are designed to restore the integrity of a tooth that has been compromised by significant decay or trauma. They cover the entire visible portion of a tooth above the gum line, which helps prevent further damage, preserves the remaining tooth structure, and allows for normal function in chewing.

While enhancing aesthetics can be a factor in certain cases, especially with materials that mimic the appearance of natural teeth, the main function of a crown is to safeguard a tooth that is at risk of further damage due to its structural weakness. Likewise, although crowns can be used in cosmetic situations or in a combination with other treatments for tooth alignment, those purposes are not the primary reasons for their use. Replacing missing teeth is typically addressed through bridges or implants rather than crowns, further solidifying the crown's main role in providing support and protection to damaged teeth.
