Studies have consistently shown that when asked what feature is most significant in determining whether a person is considered to be attractive the face is listed first.  And when asked what facial feature is most important, it is their smile that comes to the top of the list. What is considered beautiful is based on standard aesthetic principles about balance and symmetry between teeth, eyes and the rest of the face.

Smile, a person’s ability to express a range of emotions with the structure and movement of the teeth and lips, can often determine how well a person can function in society. Of course, the importance given to a beautiful smile is not new. Nevertheless an organized and systematic approach is required to evaluate, diagnose and resolve aesthetic problems predictably. It is of prime importance that the final result is not dependent only on the looks alone. Our ultimate goal as your cosmetic dentist in Preston is to achieve pleasing composition in the smile by creating an arrangement of various aesthetic elements.

These features include facial aesthetics, gingival (gum) aesthetics, macro aesthetics and micro aesthetics.

 Smile Creation

Smile Design Process & Analysis

 Smile design should involve the evaluation of certain elements in a specific order;

  • facial analysis
  • The relation of the Lower jaw/Upper Jaw to the face and the dental mid-line relation to the face
  • The relationship of the teeth to the lips
  • The relationship of the teeth to the gingivae (soft tissues)
  • The intertooth and intertooth relationships, i.e., form and position along with colour of the teeth

The concept of the evaluation sequence is based starting with a macro view of the patient and progressively working down to a micro view, i.e., looking at the face first and then progressing to evaluate the individual teeth last.


Facial Aesthetics; Muscular and facial features are specific for each person. Cosmetic dentists study them visually and by analysing photographs. These features concern how the lips frame your teeth when you smile, laugh or speak. There are guidelines to facial form and balance that can be affected by dental treatment. Regardless of how attractive the teeth appear, if they do not relate to the facial structures spatially, the result will be unappealing.  Your dedicated cosmetic dentist can change these portions to produce a beautiful and pleasant smile.

Micro aesthetics; these elements concern the fine details that make teeth appear as they do. These features include unique pigmentations or marks and how they reflect light. Cosmetic dentistry produces restorations with qualities that closely resemble those of natural teeth. Natural teeth anatomy is specific to each tooth and unique to each person. The cosmetic dentist uses materials that resemble natural enamel.

Gingival Aesthetics; as gums show in smile, their appearance, form and health are important. Too much of the gums showing in a smile, spoils its beauty. Uneven gum contours, exposed root surfaces and inflammation of the gums also spoil the appeal of a smile. Cosmetic dentists are able to carry out gum lift or gum contouring to correct the smile. The most attractive smiles possess gum lines which follow the upper lip and are symmetrical. The gum line is like a frame to a beautiful painting; it will significantly enhance the appearance of your smile, or significantly detract from your smile if poor in health and shape.

Smile Width – Embrasures; The teeth towards the back of the mouth can always be seen in an attractive smile. In a narrow smile the back teeth are often in shadow (this is called negative space), thus creating the appearance of black triangles at the corners of the mouth and front teeth that stand out. Embrasures are the natural triangular spaces between the tips of the teeth. For a smile to look attractive embrasures should be smallest between the front teeth and gradually increase in size towards the back.

Macro aesthetics; this refers to the virtual proportions of facial characteristics, surrounding tissue features and front teeth that determine the beauty of the smile. These elements too can be altered to produce natural and attractive restorations in a smile makeover procedure. Your cosmetic dentist will work in collaboration with the master ceramist to employ their artistic and technical expertise to produce an aesthetically pleasing and natural looking appearance. The arrangement, sizes and shapes of individual teeth are made to complement and blend with particular features.

Golden Proportion;

Golden Proportion is a phenomenon that exists all around us. Look around yourself, items of beauty in nature; art even teeth have a common proportion. Whilst beauty cannot be measured, harmony that is associated with beauty can be expressed in a proportion. This principle of proportion has been known since the time of the Ancient Greeks. So clear-cut in principle the vast majority of dentists do not know it exists nor do they apply it in everyday practice. The ratio of 1 to 0.618 is the simplest form of the universally acclaimed Golden Proportion.

Lack of Dento-facial harmony, is non-compliant to the golden proportion. Attention is given to the disproportionate features, such as misaligned teeth, spacing, and high smile lines. A smile following the golden proportion’s blue print has the width of the central incisor in golden proportion to the width of the lateral incisor, which in turn is in golden proportion to the part of the canine that is visible from the front.

Ideal dental/facial aesthetics can be planned using the digital technology covering the Golden Proportion concept. Treatment planned using the golden proportion follows a blue-print for beauty; it is central to the smile design process. Golden Proportion is a concept that experienced cosmetic Dentists at Lane Ends Dental Practice endeavour to use, in each and every smile design.
