Principles Of Smile Design

Here are just some of the most important principals we use at Freshdental Smile Clinic to help design your smile.

Horizontal Symmetry: Draw an imaginary horizontal line through the centre of both your pupils and another horizontal line between the tips of your canine teeth. Preferably, these two horizontal lines should be parallel. Often, one side slopes down.

---

Vertical Symmetry: Draw an imaginary vertical line through the centre of your face. This mid-line should run through the centre of your eyes, nose and chin. Preferably, the mid-line should also run through your two central incisors thus making the central incisors a mirror image of each other.

---

Smile Width: Preferably, a wide smile will display your first molar to first molar tooth, although if you have a narrow smile you may only see the front six teeth from canine to canine.

---

Smile Line: Draw an imaginary curve along the bottom of your upper teeth and compare it to an imaginary curve of your lower lip. Preferably, your smile should be curved in order to appear younger.

---

Gum Line: Draw an imaginary curve along the top of your upper teeth. Preferably, only the pink triangular parts of gum between the teeth should show. Nevertheless, some people show a lot more gum or the gum that shows is irregular giving an uneven gum line.
