While it is known that citric acids can weaken teeth and cause their erosion, a new study shows a different take on vitamin c and oral health. Performed by the Friedrich University in Germany and published in the British Dental Journal, the study reported that eating grapefruits everyday may help reduce bleeding gums and heal gum disease.
The researchers involved 58 volunteers with chronic gum disease eating two grapefruits a day, and found that it had a positive effect on gum disease; this was true for smokers and non-smokers. The researchers believe that the effect is due to the increase in vitamin c.
If vitamin c is the vital component in healing bleeding gums, we are left to wonder if oranges and vitamin c supplements have the same effect.
