Usually, when our teeth are in unacceptable aesthetic conditions, our first thought, due to the old-fashioned dentistry philosophy, is to remove the damaged teeth. However, it should be the very last option.
Modern technology and materials now allow us to treat more cases without removing natural teeth. The only real reason to extract a tooth is when it is loose, fractured below the gum line or deeply decayed; other than that, your teeth can be restored through dental crowns and/or bridges which are one of the best solutions to avoid teeth extractions (if possible at all).
