Dental esthetic procedures enhance the appearance and smile of the patient.
The appearance of the smile is important to the face and to the person.
Subjective factors, such as personal preferences, influence how someone perceives dental esthetics.

The esthetic formula of the face is divided into basal bones, musculature, and teeth.
Micro esthetics focuses on individual tooth characteristics for a natural appearance.
- These include color, translucency, size, shape, surface texture, alignment, and position.
Macro esthetics focuses on the relationship between the face, lips, gingiva, and teeth.
- This includes the dental and facial midline, smile line, incisal position and length, gingival level and zenith, and anterior teeth proportion (golden proportion).

Smile design should follow a proper analysis that includes:
- Facial analysis
- Labial analysis
- Gingival analysis
- Dental analysis

Focuses on face shape, lateral profile, facial midline, and interpupillary line.

Focuses on dental midline, incisal edge length, position and display, smile line, teeth color, translucency and surface texture, teeth size and proportion, teeth shape, teeth alignment and position, interproximal contact point, and incisal embrasures.

Causes discoloration of the remaining tooth substance.
Can change tooth translucency if the pulp is involved.
Causes loss of tooth structure and form.
Can create tooth movement, such as over-eruption of opposing teeth and drifting of adjacent teeth.

Includes direct, indirect, or implant-supported restorations.
Faulty restorations can be due to improper size or shape, inaccurate color match, marginal discoloration and recession, or recurrent caries.

Can occur due to traumatic fracture, erosion, abrasion, attrition, or abfraction.

Extrinsic Stains: Stains located on the outer surfaces of teeth; can be related to poor oral hygiene, existing restorations, plaque accumulation, or eating/drinking habits; most surface stains can be removed by routine prophylactic procedures.
Intrinsic Stains: Caused by deeper internal stains or enamel defects; causative factors include hereditary disorders, medications (particularly tetracycline), excess fluoride, high fevers associated with early childhood illnesses, and other types of trauma; more difficult to treat and require more advanced procedures.

Abnormalities in teeth size, form, and position, such as midline diastema, crowding, or peg-shaped incisors, can cause problems for dental esthetics.

Losing one or more teeth due to extraction, trauma, or congenital anomalies can significantly damage the esthetics of the face and smile.

Duplicating the color of a particular tooth is difficult.
Requires duplicating the combined color of two optically different tissues: enamel and dentin.
Each substance has different optical characteristics.
The surrounding background and the observer's eye can affect color selection.
The type and intensity of illumination used for color determination can affect shade selection.
Color determination should be done under natural or neutral light illumination.
Metamerism can affect shade selection.
The restoration in the mouth can be subjected to discoloration influences (e.g., food, drinks, smoking), which may affect its color and complicate shade selection.
Lab technicians might not reproduce the exact color blending determined by the operator in case of a ceramic restoration.
Detailed shade analysis and proper communication (e.g., photographs, shade prescription sheet) between the operator and technician are crucial for the outcome of anterior esthetic restorations.

Gingival inflammation and periodontal disease can negatively affect esthetic outcomes in the long term.
Establishing definitive restorations when inflammatory periodontal problems are present not only restrains esthetic success but also accelerates the rate of periodontal destruction.
Elimination of gingival inflammation and periodontal disease is mandatory before the initiation of any restorative treatment.
The position of the restoration finish line affects gingival health and integrity.
For better esthetic outcomes, margins of crown or veneer restorations in the esthetic zone should be placed subgingivally without violating the biological width (BW is the distance from the junctional epithelium and connective tissue attachment to the root surface = 2.04 mm).
The standard today is to prepare the finish lines of the restorations slightly below the gingival margin (0.5 mm below the marginal gingiva if the sulcus depth is 1 mm, 0.5 to 1 mm if the sulcus depth is exceeding 1.5 mm).

Establishing adequate retention might be a problem if a tooth is extensively damaged, and the remaining tooth substance is inadequate to provide enough retention for the restoration.
Procedures such as full coverage preparation and intra-radicular retention might be indicated for both retention and support for extensively damaged or endodontically treated anterior teeth.

Excessive occlusal forces can cause wear of the tooth structure and put a tremendous amount of force on teeth and restorations.
Abnormal occlusal habits, such as bruxism, clenching, and habitual biting on hard objects, can cause fracture of esthetic restorations.
Esthetic restorations such as laminate veneers are contraindicated in cases where abnormal occlusal forces are present until the condition is controlled.
