Cosmetic dentistry is dedicated to solving problems related to oral health and aesthetic harmony of the mouth in its entirety.​
​The smile is one of the most important facial expressions that differentiates the human being from the rest of the animals. The smile is used as part of the language, expressing joy, happiness or pleasure. From the anatomical point of view, the smile can be analyzed by studying each of its components: lips, gums and teeth.​
​Currently, there are techniques and materials that allow treatments for cosmetic purposes that restore the patient ‘s adequate function and aesthetics. Basically, the treatments available for aesthetic purposes can be classified into the following: ​

1. 1. Hygiene treatments and prophylaxis.
2. 2. Treatments with microabrasion enamel techniques​.
3. 3. Aesthetic contouring.
4. 4. Treatments with whitening techniques​.
5. 5. Restorative treatments with composite resins or dental porcelain.
6. 6. Orthodontic or orthognathic treatments.
7. 7. Periodontal treatments​​.

These treatments are simple, painless and can be performed in few sessions without the need to wear the teeth and achieving 100% effective results. Some of the causes for which patients can resort to these treatments are:​

1. Dental asymmetries (crowded or uneven teeth that generate an unpleasant appearance despite being healthy and sanitized).
2. Inter-incisive diseases (separation between anterior teeth).
3. Changes in coloration or pigmented or stained teeth (either by medications or different infusions such as coffee, tea, or mate, and substances such as cigarettes)​.
4. Cavities in the tooth’s neck (lesions in the area of ​​the tooth closest to the gum that generates an unpleasant appearance).
5. Fractures of teeth.
