Facial Esthetics

When you visit your local dentist for a smile makeover, your dental professional will inspect the facial and muscular considerations of your face, jaw, mouth, and teeth. Many dentists utilize a visual or photographic analysis to do so. Facial esthetics include how your lips frame your mouth when you speak, smile or laugh.

Gingival Esthetics

Also known as gum esthetics, gingival esthetics revolve around the health and appearance of your gums. If you have a gummy smile, uneven gum lines, inflammation of the gums, or exposed root surfaces, your dentist may recommend a form of oral surgery to fix the problem.


Microesthetics involves the subtle and unique characteristics of your teeth that make them appear the way they do. This can include how your teeth reflect in the light, unique marks or colorations, and other exterior characteristics.


Macroesthetics analyzes the relationships and proportions between your front teeth, facial characteristics, and oral tissue landmarks. When you work in collaboration with your cosmetic dentist, they will use their technical and artistic abilities to create a natural and pleasing appearance in which all of your teeth blend and complement your unique features.

The Main Components Of A Smile

When you schedule an appointment at Gentle Care Dentists in Arlington, our dental professionals will conduct a comprehensive oral exam of your teeth, mouth, jaw, and gums before recommending the best dental treatment for you. If you’re interested in cosmetic dentistry to restore parts of your smile, your dentist will assess some of the main components of your smile, which include:

Your lips are the frame of your smile, and having well proportioned lips can add symmetry to your smile. If you want to enhance or correct the shape of your smile, there are techniques that can be used to make your lips appear fuller. For optimal esthetics, your facial features should align with your teeth and lips. In most youthful smiles, the upper front teeth should fill between 75 to 100 percent of the space between your upper and lower lips.



Most dentists will tell you that the starting point of any smile design is the facial midline. This is an imaginary vertical line that one can draw between their front two upper teeth. For optimal esthetics, the facial midline should be centered in the middle of the face. Unfortunately, other facial features such as the eyes, nose, and chin can be confusing when you are trying to locate the midline of the face. For instance, if your eyes are at slightly different levels, or your nose is tilted a little to the left, it can be difficult to determine your facial midline.

An even more accurate approach to determining the facial midline focuses on two facial landmarks: a point between the eyebrows and the Cupid’s bow, which is located in the center of the upper lip. By drawing a line between these two landmarks, dentists can locate the position of the facial midline.

Smile Line

In an ideal smile line, the edges of your upper teeth should be parallel to your lower lip when you smile. The bottom of your lower lip should have the same line as the gums of your lower jaw. Regardless of the size or shape of your smile, this should always be the standard. Once your dentist has determined the orientation of your smile line, he or she will be able to design the best curve or shape for your new restoration procedure.


The ideal smile is one with white, unstained, and straight teeth. If your teeth are uneven or you suffer from overcrowding, your dentist may recommend a variety of orthodontic procedures to help correct your smile. When you smile with your pearly whites, your top teeth should be in good proportion to your gums.

As you can see, there are many factors that make up a smile design and various characteristics that make up your smile.
