What is the average length of the teeth? Importance in dental aesthetics

In recent years, dentistry has undergone a change in which the demand for dental aesthetics has increased. Advances in preventative dentistry, in adhesive dentistry, a better understanding of tooth decay and periodontal disease, has gradually shifted the needs of patients from carious tooth restoration to gradually giving the value to the teeth that people assign. This oriented not only in dental function, but also in aesthetics.

People aspire to improve their dental aesthetics in order to look better, but mainly to feel better. Faced with this reality dentistry has responded by refining its observation parameters and joining their efforts for the best evaluation of clinical reality, with which cosmetic dentistry has been increased and is currently on the rise.

During the evaluation of a person’s smile, it is considered prudent to observe the face in its entirety, that is, to observe the facial expression in a complete and integrated way, so that for example you will find that many people present an attractive smile, which is not technically perfect from a dental perspective, however the impression is that when the smile “fits” on the face, the dental imperfection is not always considered a disorder or asymmetry.

There are many parameters for the analysis of dental aesthetics, among which stand out the interincisal space, the midline, the position of the incisal edges, the smile line and the length of the teeth, that is, their size and the coronary proportion.

The length of the teeth varies depending on age, gender, dental group and other factors involved. The young permanent teeth in the upper anterior zone have a standard width to height ratio of 0.81, with the exception of the canine, which is longer in males, determining the ratio of 0.77 for this tooth.

In general, the anterior teeth (central incisor, lateral incisor and canine) have relationships that can be classified the same for men and the same for women. So that:

  • The central incisor it has a width of 8.59 millimeters for men and 8.06 for women. Similarly, the length is an average of 10.19 for men and 9.93 for women.
  • The lateral incisor the width in men is an average of 6.59 millimeters and in women 6.13 millimeters. The length, 8.7 in men and 7.79 in women.
  • The canine it has an average width of 7.64 for men and 7.15 for women. The length for men is 10.06 and for women the average is 8.89.

So that gender is influenced above all in the previous sector since the male sex has greater proportions while the anterior teeth of the female sex are smaller.

The knowledge, monitoring and balance of the aesthetic parameters in an individualized way, allow greater precision in the definition of the conflicts that the diagnostic and therapeutic stages of the upper dental arch of each patient present in aesthetic dentistry.
