SUN AND VITAMIN D: Sun's rays makes vitamin d in the skin which in turn helps absortion of calcium from the intestine . The absorbed calcium then makes the bone and teeth stronger.

No: Long term exposure to uv light is unhealthy. However, we need some uv light from the sun to produce vitamin d. Vitamin d is important in regulating bone density and osteoporosis. Vitamin d deficiencies have been linked to tooth loss, and periodontal risk factors like low bone mass. Also vitamin d may act as an anti inflammatory agent and stimulate the production of oral anti microbial peptide.
