Background: Tooth restoration is a common, routine procedure among dentists but still has its own difficulties especially for posterior teeth. As it is a straightforward procedure, some dentists are not aware of the difficulties that may contribute in reducing the longevity of the filling.

Objective: To determine the difficulties encountered during and after placement of restorative materials in deep cavities.

Study Design: Cross sectional

Place and Duration of Study: Department of Operative Dentistry, Bahria University Dental College from 1^st November 2020 - 30^th April 2021.

Methodology: Three hundred and fifteen populations of general dental practitioners practicing in different settings of Karachi were enrolled. Standardized questionnaires were divided randomly among general private dental practitioners in Karachi. The preference of dentists towards the ideal material for posterior restorations was evaluated through their recorded response.

Results: The mean age of patients was 25.2±4.2 years with 64.8% females and 35.2% males.  Amalgam was used in deep cavity by 52.4% practitioners while composite was opted in shallow and moderate cavities by 63.2% and 62.9% practitioners respectively.

Conclusion: Matching tooth-colored restorations is a common practice with amalgam used for deep cavity and composite in shallow and moderate cavity restoration.
