The amount of tooth space viewed when a patient smiles

The term "smile line" specifically refers to the amount of tooth space that is visible when a patient smiles. This concept is significant in dentistry and cosmetic procedures because it relates to the aesthetic appearance of a smile. A well-defined smile line enhances the overall attractiveness of a person's smile by showcasing the teeth effectively.

The smile line is influenced by various factors, including the alignment and placement of the teeth in relation to the lips and facial structure. Essentially, this term helps dentists and orthodontists assess how much of the upper teeth appear when an individual smiles, which contributes to smile design and restorative dental work.

Understanding the smile line is critical for making decisions about elective procedures, orthodontic treatment, or cosmetic enhancements, all aimed at achieving a harmonious and attractive smile.
