Fluoride is often used in toothpaste and drinking water to prevent tooth decay. While it has dental health benefits, there are also concerns about the potential adverse effects of excessive fluoride exposure. Here are some reasons why fluoride may be considered bad for health:
- Fluorosis : Excessive fluoride intake during tooth development can lead to dental fluorosis, a condition manifested by discoloration and damage to tooth enamel.
- Bone problems : Long-term exposure to high levels of fluoride can lead to skeletal fluorosis, a condition that affects bones and joints and can lead to pain and damage to the skeleton.
-
Cognitive effects : Some studies have suggested that high fluoride intake in children may be associated with impaired cognitive development and lower IQ. However, these studies are controversial and more research is needed to draw definitive conclusions.
- Hormonal disruptions : Fluoride can affect the functioning of the thyroid gland, which can lead to hormonal imbalance and health problems such as hypothyroidism.
- Kidney and liver problems : People with pre-existing kidney or liver conditions may be more sensitive to the effects of fluoride because these organs play a role in the excretion of fluoride from the body.
