A filling is a way to restore a tooth damaged by decay back to its normal function and shape. If you have a tooth that requires a filling, the dentist will first remove the decayed tooth material, clean the affected area, and then fill the cleaned out cavity with a filling material. A filling also helps prevent further decay by closing off any cracks or spaces where bacteria can enter.
Composite (plastic) resins are custom made to the exact color of your natural teeth, creating a more natural appearance. While white fillings may be less noticeable than other materials, they usually only last between 3 and 10 years. They may not be ideal for large fillings as they may chip or wear over time. They can also become stained from coffee, tea or tobacco.
