Dental pits, or caries, are little gaps in the hard surface of the teeth. They are caused by microbes on the surface of teeth making corrosive out of sugar. The most widely recognized offender is a bacterium known as Streptococcus mutans.
The microbes frame a sticky film known as plaque. The acids in plaque expel minerals from (demineralize) your veneer — a covering of the teeth made for the most part of calcium and phosphate. This disintegration causes modest openings in the finish. When the corrosive harm spreads into the dentin layer underneath the veneer, a depression frames.
