The 21 Principles of Smile Design#1:Central IncisorWidth / HeightRatioDo your front incisor teeth appear taller than they are wide like an up-rightrectangle, not a square? The width/height ratio should be 75-80 %. Forexample, if the width were 8.0 mm and the height 10 mm, the ratio (8/10)would equal 80%.9
The 21 Principles of Smile Design#2: MesialInclinationAre your teeth angledproperly? Each upper toothvisible in the smile shouldhave a slight inclination ortilt that is toward the midline(mesial) of the mouth. If theseimaginary lines were extendeddownward they would meet orconverge at or near the navel point over the stomach.10
The 21 Principles of Smile Design11
The 21 Principles of Smile Design#3: MidlinePlacementand CantIs your smile centered onyour face and in your mouth?The position of the mid-linebetween the central incisorsshould be on a line drawnfrom between the eyes anddown through the nose,lips and chin. The angle ofthe mid-line should not becanted or tilted to the left orright, but should be straightup and down.12
The 21 Principles of Smile Design#4: Color,Shading, Stains,and MarkingsAre the teeth a uniform bright coloror shade? Is one tooth darker thanthe rest? Are there white or darkspots or markings on the enamel?13
The 21 Principles of Smile Design14
The 21 Principles of Smile Design#5: Smile at RestEvaluate the amount of teeth showingat rest or with a slight smile. Middleaged adults should show 2-4 mmof their upper teeth. This amountdecreases with age as the “window”of the mouth begins to sag downwardshowing more of the lower teeth.15
The 21 Principles of Smile Design#6:Gum LineSymmetryThe gum tissue framesthe teeth and formsa “curtain” for theteeth. Is the heightand scalloping of thegum line symmetricalor matched evenlybetween the left andright sides? Balanceand symmetry areimportant partsof what makes anattractive smile.16
The 21 Principles of Smile Design#7:Gum LineMarginHeightsIs the level of the gum line over the lateral incisor lower than the centralincisor? The height of the gum line margin over the lateral incisors should beslightly lower than the height of the gums over the adjacent central incisor andcanine teeth.17
The 21 Principles of Smile Design#8:Gaps orDiastema:A “diastema” is a gap between the teeth. Is there a space between your frontteeth?18
The 21 Principles of Smile Design#9:Gummy SmileA “gummy smile” is when too muchgum tissue shows above your frontteeth when you smile. How muchgum tissue shows with a full happysmile? Ideally there should be onlya slight amount (1 to 3 mm) of gumtissue showing above the front teethwhen you smile.19
The 21 Principles of Smile Design#10:Gingival ZenithWhat is the location of the uppermost height of the gum line over each tooth?The height of the gum line across the face of each tooth varies from tooth totooth. It should be centered over each lateral incisor, and it should be 2/3rds ofthe way across the face of the tooth for the central incisors and canine teeth.20
The 21 Principles of Smile Design#11:Smile LineFollows LipDoes your smile linegenerally follow your lowerlip line? The incisal orbiting edge of the upperteeth should parallel orfollow the contour of thelower lip line in a relaxedor slight smile.21
The 21 Principles of Smile Design#12:HorizontalPlaneAre your teeth on aparallel horizontal planewith your eyes or withthe floor? The left to righthorizontal biting plane ofthe mouth should parallelthe floor or the horizonwhen standing. It shouldalso parallel a line drawnbetween the eyes (theinter-pupillary line). Thehorizontal plane fromthe front to the back ofthe mouth should alsogenerally parallel the floor.(Note: some people’s eyesare not level in nature.)22
The 21 Principles of Smile Design#13: GumTissueHealth/BadBreathDo your gums bleedwhen you brush or floss,or are they inflamed orred around the borders?Healthy gums do not bleedand are light pink in colorand are stippled in texture(like an orange peel). Gumdisease is linked to heartdisease and can be veryunsightly – and smelly!Oral bacteria cause toothdecay, gum disease andbad breath! Any plan for anattractive smile and goodoral health must includeregular dental cleaningsand good oral hygienepractices.23
The 21 Principles of Smile Design#14:FlossingContactPointDoes the pointof tooth contactbetween front teethgradually migrateupwards fromtooth to tooth? Theflossing contact pointbetween these teethshould step upwardwith each tooth.24

The 21 Principles of Smile Design#15:Mal-alignment or CrowdingTeeth should be even and straight. Are your teeth crooked or crowded in theirpositioning? Is there room for your teeth in a natural arch form with each toothstanding evenly side by side? Crowding happens when there isn’t enough roomfor them or when the jaws are too small.26
The 21 Principles of Smile Design#16:IncisalEmbrasureIs there good definitionand separation betweenthe front teeth on theincisal edge of the teeth?The size of the silhouetteor outline shape betweenthe front teeth shouldsymmetrically increase insize moving away from themidline. This is best seenas a triangle shape wedgebetween the teeth and onthe biting edge of the frontteeth.27
The 21 Principles of Smile DesignThe Golden Proportionwas used in ancient Greekarchitecture and in thegreat art of the ages. It canbe observed throughoutnature and the humanbody. Its principles areused in modern buildingconstruction, car designand clothing. The balanceand harmony it creates ispleasing to the eye.Cosmetic dentists usethe Golden Proportion tocreate a pleasing smile thatis balanced with the face.28
The 21 Principles of Smile Design#17: GoldenProportionRatioAre your teeth sized in the properproportion? The Golden Proportionfollows the “rule of thirds”. Eachtooth away from the midlineshould be two-thirds as wide asthe previous tooth. For example:Measure the width of a centralincisor in your mouth or on aphotograph. Divide this width bythe width of the lateral incisor nextto it. The central incisor should be1.6 times as wide as the lateral,and the canine 0.6 times as wide asthe lateral, and so forth.(Example: Ideally, if the centralincisor is 10 mm wide, the lateralincisor should be two-thirds of thisamount, or about 6.5 mm, and thecanine should be two thirds of thator about 4.4 mm)29
The 21 Principles of Smile Design#18:BlackTriangleIs there a dark space at the gum line between the front teeth? A “blacktriangle” appears between the front teeth when the teeth are too far apart orthe underlying bone level dissolves away. When this happens, the gum papillashrinks and allows the
