What is the maximum space allowed between a tooth when fitting a temporary crown?

The maximum space allowed between a tooth when fitting a temporary crown is 0.5 mm. This measurement is important because a well-fitted temporary crown should closely adapt to the prepared tooth and adjacent teeth to ensure proper function and esthetics while the patient waits for a permanent restoration.

When the space between the temporary crown and the tooth is too large, it can lead to food impaction, discomfort, and an increased risk for decay in the prepared area. A 0.5 mm gap provides enough room to account for slight movements or adjustments in positioning without compromising the integrity of the temporary crown's fit. A gap larger than this can also affect how the crown retains its position and may compromise the overall success of the treatment as the crown may not adequately protect the tooth structure.

Thus, maintaining this specific and limited distance is crucial in fostering optimal healing, protecting the tooth, and preparing the patient for the forthcoming permanent crown.
