Resin restoration is a commonly used dental restoration method, with certain indications, not all patients can restore the defective teeth with resin restoration, only the suitable treatment for the patient is good. Resin restoration is suitable for those who have a small range of tooth tissue loss caused by caries, wedge-shaped defect, trauma, etc. The advantages are realistic and beautiful color, simple and quick restoration, and operation in the mouth, which can save more healthy tooth tissue and thus better restore the shape and chewing function of teeth. The disadvantage of resin restorations is that the material may discolor and produce pigmentation, which affects the aesthetics. The strength of resin material is lower than that of porcelain crown restoration, so for large area of tooth defects, as well as teeth after root canal treatment, or even subgingival tooth defects, it is not suitable for resin restoration to fill the affected teeth, and other restorative methods such as inlays and porcelain crown restoration may be required. Therefore, patients with dental defects are advised to visit the dentist to choose the appropriate restoration method at the doctor’s discretion. If the indication is met, the resin restoration can be a one-time solution and is a better way to restore a chipped tooth.
