Until recently, dentists filled and sealed cavities exclusively using a silver and mercury amalgam. Unfortunately, these fillings (or restorations) often weaken teeth due to the large amount of the original tooth that has to be removed.
Modern dentistry has increasingly turned to composite teeth fillings as a strong, safe and more natural looking alternative. Composite fillings utilize a tooth colored resin that is bonded to the tooth creating increased strength to the previously compromised tooth.
Many times we can use the Laser to remove the cavity without anesthesia!
