Unattractive Smile Factors

1. Tooth Colour
Dark tooth colour creates an unattractive smile. Teeth whitening or Dental Veneers can help you overcome this.
2. Smile Arc
The maxillary gum line and the incisal edge together create the curve of your smile. It should create a slight upward curve and narrow towards the end. If the curve is not as mentioned, it creates an unattractive reverse smile. Veneers and Cosmetic Dentistry can help you overcome this.
3. Gum Display
The combination of lip muscles that activate when you smile determines how much of your gums would be visible when you smile or laugh. Too much gum display leads to a gummy smile and too little gum display makes the smile look toothy or too old. Cosmetic Dentistry and Gummy smile correction can be helpful in such cases.

4. Gum Colour
Dark gum colour causes a contrast between the colour of the teeth and gums. Gingival depigmentation can be helpful in such cases.

5. Incisal Edge
The other line that defines your smile arc is the incisal edge. This is the edge of the upper teeth and this should be symmetrical and should curve significantly upward from the central incisors toward the molars. Disruption of this line can cause an unaestheric smile.
6. Cant
Cant is a synonymn for tilt. Ideally, the aligment of the teeth should be straight up and down. However, if they tilt forward or backward, it creates an unattractive smile.
7. Spacing
Spacing and gaps in between teeth can again result in unattractive smile.
