Delayed tooth eruption: Pathogenesis, diagnosis, and treatment. A literature review


Delayed tooth eruption (DTE) is the emergence of a tooth into the oral cavity at a time that deviates significantly from norms established for different races, ethnicities, and sexes.

This article reviews the local and systemic conditions under which DTE has been reported to occur. The terminology related to disturbances in tooth eruption is also reviewed and clarified.

A diagnostic algorithm is proposed to aid the clinician in the diagnosis and treatment planning of DTE.

The sequential and timely eruption of teeth is critical to the timing of treatment and the selection of an orthodontic treatment modality. This review addresses the need for a more in-depth understanding of the underlying pathophysiology of DTE and gives the clinician a methodology to approach its diagnosis and treatment.

Eruption is the axial movement of a tooth from its nonfunctional position in the bone to functional occlusion. However, eruption is often used to indicate the moment of emergence of the tooth into the oral cavity.

The normal eruption of deciduous and permanent teeth into the oral cavity occurs over a broad chronologic age range.

Racial, ethnic, sexual, and individual factors can influence eruption and are usually considered in determining the standards of normal eruption.

True and significant deviations from accepted norms of eruption time are often observed in clinical practice. Premature eruption has been noted, but delayed tooth eruption (DTE) is the most commonly encountered deviation from normal eruption time.
