Florua is a natural mineral found in water, soil and food. Thanks to its ability to enhance tooth enamel and prevent tooth decay, this substance has been added to the water supply and toothpaste systems in many countries, including the US, since the 1940s.
According to the recommendation of the US Public Health Agency, the ideal domestic florua level for use is 0.7 milligrams per liter. This is considered a safe threshold, helping to prevent tooth decay without causing long-term health impacts.
When used properly, florua is one of the important achievements of 20th-century preventive medicine. However, overuse can lead to unwanted negative effects," said Mary Choy, Ph.D., a clinical pharmaceutical expert in New York, verywellhealth.
Benefits of using it properly
Florua has the effect of strengthening tooth enamel, increasing tooth resistance to acid and helping to recover early damage caused by tooth decay. According to studies, adding florua to domestic water has significantly reduced the rate of tooth decay in both children and adults.
You can receive florua through many sources such as:
Toothpaste and mouthwash containing florua
soon-to-be (especially in major cities in the US)
Some foods such as tea, coffee, shrimp and processed foods made from floating water
Gel florua for dental use
Side effects of overdose
Although beneficial, consuming too much florua, especially in young children, can lead to:
Tooth fluoritis: white spots or brown streaks appear on the teeth when children receive too much flounder while their teeth are developing. In severe cases, cavities and discoloration of tooth enamel can occur.
fluoridated bone disease: a rare disease that causes pain in bones, stiffness and deformity usually only occurs when exposed to extremely high float content for a long time.
Concerns about brain development: Some preliminary studies show that long-term exposure to large amounts of florua can affect children's intelligence. However, these studies are often at unusually high florua levels, which are not consistent with daily use in the US.
Notes when using
Children under 3 years old should only use toothpaste containing rice float.
Children aged 36 should consume the same amount as tofu and should be instructed not to swallow.
well water needs to be checked periodically to determine the natural floating content.
If you use bottled water, you should consult your dentist because not all types of florua have florua content on the label.
There is no danger if we understand and control well. Florua is still a powerful weapon in preventing tooth decay - but it needs to be used properly, in the right amount," emphasized pharmacist Mary Choy.
