A natural compound found in grapes has been found to strengthen teeth and prevent tooth decay. Grape seed extract,
a byproduct of the wine making industry has been linked to reduction in tooth extractions.
The extract has been found to toughen dentin, the tissue that makes up the bulk of the tooth which lies beneath the hard external enamel.
Tooth decay occur when acid is produced from plaque, which builds up on teeth. When we consume food high in sugar the bacteria in plaque turn the sugar into energy they need to produce acid.
If the plaque is allowed to build up, the acid can begin to break down the surface of tooth, causing cavities. The cavity begins to eat away at the second level of tooth material that lies beneath the enamel: the dentin.
Damage collagen can repair itself with a combination of plant-based oligomeric proanthocyanidins – flavonoids found in most foods and vegetables and extracts from grape seeds.
