Can my teeth be re-bonded to match the rest of teeth? (Photo)

The darkened color of your front tooth suggests that it may have been traumatized.   You should have the tooth checked for any nerve damage prior to any bonding.  Because  your tooth is so dark it may be difficult to match your other front tooth by bonding over it.   If a root canal is necessary because of nerve damage, then a full crown would be required.   This would cover  and mask out the darkness of your tooth, if  your dentist chooses the correct material for the crown.  If a root canal is not needed, The dark tooth  would need to be reduced to allow for a thick layer of material of either resin or porcelain. Then you could have your two front teeth restored with either resin bonded veneers or porcelain veneers so that they match in color and that your space is closed.

Hi:Good question.  You can definitely get the tooth rebonded to match the rest of your teeth.Best,Dr. Maddahi

Yes, you can rebond the tooth to match the color of your teeth and close the gap.  However, I think moving the teeth to address concerns about your gap is a better and more conservative option. I think a express smiles treatment which will take 2-4 months to treat this is the best way to go.
