Can a Filling on the Front of the Incisors Be Refilled if It Becomes Stained?

It sounds like the most conservative approach to solving your concern is with a composite filling; however, if the tooth discoloration is superficial it can sometimes be removed with "micro-abrasion." Discolorations most easily treated with micro-abrasion are white spots. This procedure would eliminate the need for any kind of restoration. If the discolorations can not be removed with micro-abrasion then a conservative composite can be placed. These types of restorations last a very long time and should not discolor.

Good luck!

A stained restoration may need to be replaced due to decay. However, if a restoration has stained and does not have decay, it may be polished/buffed with polishing discs to revitalize it. This will help the restoration to blend naturally with the tooth again and improve the overall aesthetics.

If your tooth is perfectly healthy and the existing filling is just discolored and do not understand why you can not veneer it. Maybe a photo of it will be best to evaluate and answer you question with more specific options. Regardless, you can upgrade the existing filling, making the tooth to look healthy and natural. Teeth bonding is done with a composite resin that can restore both aesthetics and function to your smile. Placed on both the front and back of teeth, the composite resin used in teeth bonding provides a strong, long-lasting, and seamless appearance to smiles. As you know the material used in teeth bonding is not as strong as other restorative options, and may discolor, chip, or break over time.  Colored and shaped to precisely match adjacent teeth, composite resin is unnoticeable, and provides for a seamless, natural looking smile.
