Why Teeth Erupt Late?

Delayed tooth eruption

• Eruption is the axial movement of a tooth from its nonfunctional position in the bone to functional occlusion. 
• 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 chronological 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.

Treatment for Delayed Erupting teeth (DE)

Delayed eruption presents a challenge for orthodontic treatment planning. A number of techniques have been suggested for treating. The main considerations for teeth affected by DE are

• the decision to remove or retain the tooth or teeth affected by DE, 
• the use of surgery to remove obstructions, 
• surgical exposure of teeth affected by DE, 
• the application of orthodontic traction, 
• the need for space creation and maintenance, and 
• diagnosis and treatment of systemic disease that causes DE.
