Cosmetic fillings are made up of a material called composite. These filings are commonly done in front teeth (anterior teeth) to repair damaged, decayed, or fractured teeth, create gap closure in the midline (midline diastema), and create a flawless smile by closing small gaps in between the teeth. These fillings are also used in back teeth (posterior teeth) to fill cavities that exactly match the tooth color and camouflage the fillings as natural teeth. Dentist clear your affected teeth out, apply composite over them, and then shape and polish them until they match the natural color of the teeth. This filling is better than conventional filling material in terms of strength, longevity, and appearance. Cosmetic dental fillings are still an inexpensive treatment.
