The golden ratio is exhibited throughout nature.
A perfect smile does not occur by chance, it is carefully planned and excuted with averages, ratios and most importantly your input. While most people don't know exactly what constitutes a nice smile, most will recognise a nice smile when they see one. What one notices are some of the principles below, just minus all the numbers!
The ancient Greeks introduced and understood the important parameters of beauty and called it the "golden proportion". These proportions have long been used by famous artists, builders and designers for thosands of years. We use principles to create a smile that looks natural and is pleasing to the eye.
Outlined below are just a few of the many principles practiced here. There are many other elements other than having whiter teeth that make for a radiant or confident smile.
Do you feel connfident when you smile? Do you worry what other think about you because of your smile?
Does you smile hold you back socially or does it affect your career?
Have you recently had dental work that sticks out and is noticeably fake?
Do you cover or hold back your smile in pictures?
Are your teeth straight or are they crowded?
Do you like the colour of your teeth?
Are you missing back teeth missing causing wearing of your front teeth and an aged look on your face?
Do you have dark fillings showing in your smile?
Central Incisor Width/height Ratio
Do you have short square looking incisors or tall long incisors? Depending on your face shape we will make sure that the width/height ratio is between 75-85%. E.g if incisor width is 7.5mm and height 10mm, your ratio would be 75%.
If you are grossly under or over we can get you closer using modern restorative techniques such as crown lengthing coupled with crown and veneers. We tend to use lower ratios for a more feminine look, or a higher ratio for a squarish and masculine look. Mesial Inclination
All upper teeth should have a slight tilt toward the middle of the mouth.
Your smile should be centered on your face and in your mouth. It is an imaginary line that disects the eyebrows; eyes; nose; central incisors and chin. It should not be tilted left or right but perpendicular to the horizontal place of your eyes.
Colour, Shading, Stains and Markngs
Are there any old fillings, inherited stains on your teeth? Are they yellowing becasue of age or lifestyle habits? Are they all the same colour or has one tooth had root treatment and greyed?
Smile at rest
How much of your upper central incisors are showing at rest or with you slightly smiling? It should be between 2-4mm. If lest than this you may have signs of wear or a shallow full smile. As you get older you naturally show less of your upper teeth and more of your lower teeth.
Smile Line Follows Lip
Your upper teeth should follow the gentle curve that you lower lip outlines when you are slightly smiling.
Gum Line Symmetry,Margin Heights, and Gingival Zenith
The gum tissue frames the teeth. Is the height and the scalloping of the gum line symmetrical or matched veenly between the left and right sides? An aesthetic smile has both balance and symmetry.
The level of the gums over the central incisors and the canines should be slightly higher than that of the laterals. Often with mislaigned and crowded teeth, height will vary greatly. With modern
alignment techniques gums margins can be corrected by simply moving the teeth as the gum tissue and supporting bone will follow.
The position of the highest point (zenith) in a aesthetic smile is pushed slightly away from the midline on the centrals and canines. The laterals the highest point is the center of the tooth.
Gaps or Diastema
A gap or diastema is a space between your front teeth. It could be due to advanced gum disease which can result in drifting of the incisors, or due to a prominent upper lip attachement that prevent the central incisors from meeting. Do you have a space?
The horizontal left to right biting plabe of the mouth should parallel the floor and/or the inter-pupillary line. Are your teeth higher/ lower on one side of the midline than the other?
Gum Tissue Health/Bad Breath
Do your gums bleeds when brushing? Do they look red and inflammed where your teeth and gums meet? If so, the first and most important aspect of smile mapping is to improve your
gum health through regular cleans and excellent oral hygiene practices. Gum disease can cause bad breath, and premature loss of teeth.
Flossing Contact Point
As you move away fromt the midline the flossing contact point (where your floss "snaps" in, should progressively get higher as you work your way to the canines. A high calibre ceramist or dentist would implement this into there work as it will have a direct impact on the amount of gingival scalloping and hygiene, and therefore the overall smile.
Mal-alignment or Crowding
Teeth should be well aligned and straight. Crowded teeth are harder to clean and maintain, and by extension more prone to decay. Are your teeth standing evenly side by side?Just after improving gum health,
relieving crowding is the natural next step to an attractive smile. Incisal Embrasure
There should be a slight but noticeable definition between the edges of the teeth. They should get slightly larger as you move away from the midline of your mouth.
Golden Proportion Ratio
Your teeth should be in line with proper proportions. It follows the rule of thirds. The central incisor should be 1.6 tims the size of the lateral, while the canine (visible in the smile) should be 0.6 times the width of the lateral incisor.
Poorly shaped crowns or fillings will often leave a small dark space between the teeth. This can also be due to the underlying bone receeding from gum disease, and when this occurs the gingival papilla goes with it.
The vertical distance between your nose and the chin should be equal to the other two facial thirds. A shorter one third of your lower face (vertical dimension) makes your face appear older. Ideally the distance betwen the gum line of the top and bottom central incisor when biting down should be around 17-21mm.
Our unique examination, consultation and written treatment plan includes a through assesemnt of the above and more.
