It is known that teeth can protect themselves, to some extent, from attack by bacteria but that inflammation within a tooth can be damaging and, in extreme cases, lead to abscess or death of the tooth. New research shows that odontoblast cells are part of the immune system and fight to protect teeth from decay.
A study conducted in four American Indian communities in the Pacific Northwest presents an effective strategy to convince mothers to switch young children from drinking sweetened soda to water and shows that eliminating these sugary drinks from the diets of the youngest members of the tribe significantly decreased tooth decay.
