Excessive consumption of green tea or tea in general has been associated with a condition called skeletal fluorosis, this is a condition in which too much fluoride is ingested, this may lead to joint(articulation) pain and other arthralgias(pain in a joint). The bones become brittle and weak, they also lose density which increases the risk of fracture. Periodontal disease has also been noted.

It seems that well water may also be a culprit due to high levels of fluoride. Unfortunately, I can't quantitate "excessive" amounts for you and have been unable to find any data on how much qaulifies for excessive.

A group of researchers in Hong Kong studied the relationship between green tea and health improvement of the skeletal system. They have shown that green tea used worldwide as a beverage or food supplements, contains a group of substances that can stimulate osteogenesis and slow down the processes of bone degradation. Green tea has the potential to contribute to the prevention and treatment of osteoporosis and other skeletal diseases.

The researchers exposed, for a few days, a group of cells that induce the synthesis of bone (osteoblasts) on 3 major components of green tea. They particularly noted that the main component of green tea  enlarged the activity of key enzymes that promote bone growth to 79%.

It also was increased significantly, bone mineral levels in the cells, which cause strengthening bones.The increased levels of this component has blocked the activity of osteoclasts, cells with a role in bone resorption.

The researchers pointed out that there were not shown toxic effects of green tea on bone cells.
