Cracked Tooth Syndrome
Dentists call natural looking white fillings, posterior composites. 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 and have the disadvantage of causing the tooth to darken as they age. Modern dentistry has increasingly turned to composite fillings as a strong, safe and more natural looking alternative.
