Smile design is a sub-branch of aesthetic dentistry and aims to create a smile that is appropriate to the person’s face shape, gender, age, and personal preferences. This process is customized according to the individual’s both aesthetic and functional needs. Smile design is a natural three-dimensional design that is compatible with the closure between the upper and lower teeth, the soft tissue surrounding the teeth, and the patient’s facial characteristics.

The aim of the ideal smile design is to provide aesthetics with the most conservative approach possible, that is, with minimal touch on the tooth structures. This smile we create should be both aesthetically and functionally functional. Our duty as a dentist is to provide the best aesthetics in our patients with careful diagnosis, analysis and treatment.

An indispensable element of a perfect smile design is that the tissues surrounding the teeth have a healthy structure. An ideal smile design cannot be created with atrophied papilla (the gum between two teeth), asymmetric gum levels, and excessively hyperplastic edematous gums.

Smile Design Planning Process

Patient Evaluation: Photographs, x-rays and intraoral scans are taken.
Aesthetic Analysis: Facial proportions, lip line and gingival line are analyzed.
Digital Design (DSD): A virtual simulation of the smile is made before treatment with computer-aided software.
Rehearsal (Mock-up): The design is tested with temporary materials and patient approval is obtained.
Treatment Application: As a result of the examination, a treatment plan is made in line with the patient’s wishes and complaints. Treatments such as composite bonding, laminated veneer, whitening or zirconium veneer are applied.

Aesthetic Dental Restorations

Teeth Whitening (Bleaching)

Teeth whitening is an aesthetic dental treatment applied to remove discoloration, yellowing, and stains that occur on the tooth surface over time, giving it a brighter and more aesthetic appearance. The teeth whitening process aims to lighten the natural color of the teeth and give them a brighter appearance. It can be applied with in-office whitening (in the clinic) or home whitening methods. An effective result is obtained without damaging the tooth enamel using special gels and technologies.

Causes of Tooth Discoloration

Intrinsic Discolorations: Color changes in the inner structure of the tooth (dentin). It may develop due to traumas, aging, excess fluoride, and antibiotic (tetracycline) use.
Extrinsic Discolorations: Stains on the outer surface of the tooth. It occurs due to tea, coffee, cigarettes, red wine, poor oral hygiene, and food dyes.

Teeth Whitening Methods

In-Office Whitening (Professional Whitening): Applied in the clinic by the dentist. The gums are isolated with a protective gel or barrier. A high concentration whitening gel (usually 35-40% hydrogen peroxide) is applied to the teeth. The whitening process is accelerated by activating the gel with laser or LED light. Results can be obtained in a single session (30-60 minutes). 2-3 sessions can be applied if necessary.
Home Whitening: The physician prepares custom-made transparent trays by taking the patient’s tooth size. Low concentration whitening gel (usually 10-20% carbamide peroxide) is placed in these trays. The patient uses the trays for 1-2 weeks, 4-8 hours a day.
Combined Whitening: In-office and home whitening are applied together. Fast results are obtained with clinical whitening, while permanence is achieved with home whitening.
Internal Whitening (Non-vital Whitening): Applied to root canal treated, discolored and internally stained teeth. A whitening agent is placed inside the tooth and closed with a temporary filling. Tooth color is checked for 3-5 days. When the result is obtained, the tooth is closed with a permanent filling.

Things to Consider After Whitening

Colored foods and drinks should be avoided for the first 24-48 hours.
Tea, coffee, red wine, cola, acidic and abrasive drinks, and foods with sauces should be avoided.
Smoking should be limited.
Regular tooth brushing and flossing should be ensured.
Care products recommended by the dentist should be used.

Who Is It Suitable For?

Those with yellowed, stained, or dull teeth.
Those who do not have gum disease before teeth whitening.
Those who have discoloration in their root canal treated teeth.

Who Is It Not Suitable For?

Pregnant and lactating women
Individuals under the age of 16
Those with gum disease or caries problems
Those with excessive sensitivity

Whitening Results and Permanence

The effect of whitening usually lasts between 6 months and 2 years. Permanence depends on the person’s oral hygiene and eating habits. Results can be maintained for a long time with regular care and supportive treatments when necessary.

Laminates (Leaf Veneers)

Laminate veneers are aesthetic restorations made of thin porcelain or composite materials that are attached to the front surface of the teeth. They are also called “leaf porcelain”. It is one of the most preferred methods, especially for smile design in aesthetic dentistry.

Laminate veneers are an ideal solution for patients who want a natural and aesthetic smile. It is a popular method because it requires minimal abrasion of the teeth and offers long-lasting results. However, a detailed evaluation should be made before application to determine whether it is suitable for the person’s needs and mouth structure.

Treatment Goals

Creating an aesthetic smile, eliminating discoloration in the teeth, and regulating the size, shape, and alignment of the teeth.

In Which Cases Is It Applied?

Discolorations due to coffee, cigarettes, tea
Fractures and cracks in the teeth
Interdental spaces (diastema)
Crooked and misshapen teeth
Worn enamel
Permanent stains that whitening can’t remove
Smile design for aesthetic purposes

Who Is It Not Suitable For?

Patients with severe teeth clenching (bruxism) problems
Those with serious material loss in their teeth
Patients with jaw closure disorders
Those who haven’t treated existing gum disease

Types of Laminate Veneers

Porcelain Laminate Veneer: The most preferred type in terms of aesthetics and durability. It has high light transmittance and a natural tooth appearance. Resistant to staining.
Composite Laminate Veneer: Can be applied in a single session. More economical. It is not as durable and color stable as porcelain.

Advantages of Laminate Veneers

Provides a natural appearance thanks to its light transmittance
Requires very little or no abrasion (prepless veneer)
Long-lasting and resistant to wear (10–15 years)
Resistant to stains and discoloration
Biocompatible and gum-friendly
Short treatment period (2–3 sessions)
Composite laminates can be repaired if necessary

Disadvantages of Laminate Veneers

More costly than other methods
Porcelain can break if excessive force is applied
If abrasion is done, the process cannot be reversed
Avoid biting hard objects (pen, nails, etc.)

How Is Laminate Applied?

The condition of the teeth is evaluated and a treatment plan is created.
Digital smile design (DSD) can be done.
Approximately 0.3-0.7 mm of abrasion is made from the front surface. Prepless application is also possible.
Tooth size is taken and sent to the lab.
A temporary veneer is applied.
Final porcelain veneers are bonded with special adhesive.

Laminate Care and Usage Recommendations

Avoid biting hard objects (pen, nail, etc.)
Use a night guard if you clench or grind your teeth
Maintain good oral hygiene with regular brushing and flossing
Avoid acidic and abrasive foods
Visit your dentist every 6 months for check-ups
