fluoride
Definition
Fluoride is a chemical element with the symbol F and atomic number 9. It is the most electronegative element, and it is the most abundant halogen. Fluoride is a naturally occurring mineral, and it is also added to water and toothpaste to help prevent tooth decay.
Fluoride helps to strengthen tooth enamel, which is the hard outer layer of teeth. This makes teeth more resistant to acids produced by bacteria in the mouth.
Fluoride can also help to repair early signs of tooth decay. This is why it is important to brush your teeth with fluoride toothpaste and to drink fluoridated water.
The amount of fluoride that is needed to prevent tooth decay varies depending on the individual. However, most experts recommend that children and adults get about 1.5 milligrams of fluoride per day.
Too much fluoride can be harmful, and it can cause a condition called fluorosis. Fluorosis can cause white spots or brown streaks on teeth.
It is important to talk to your dentist about how much fluoride you need to prevent tooth decay and avoid getting too much fluoride.
How can the word be used?
Fluoride is a chemical compound that contains the element fluorine.
Different forms of the word
Noun: fluoride, fluorides.
Adjective: fluoic.
Verb: fluoridate, fluorinated, fluoridating.
Etymology
The word "fluoride" is derived from the Latin word fluor, which means "flow". The Latin word fluor is also the root of the word "fluorine", which is the element that fluoride contains.
Question
What can fluoride help with?
AQA Science Exam Question and Answer
Question:
Explain the significance of fluoride in dental health and its role in preventing tooth decay. Describe the process of how fluoride interacts with tooth enamel to promote dental hygiene. Provide real-life examples of how fluoride is incorporated into dental products and public water supplies to improve oral health.
Answer:
Fluoride is a significant component in dental health, playing a crucial role in preventing tooth decay. When fluoride is present in the mouth, it reacts with the tooth enamel, forming a more resistant compound called fluorapatite. This fluorapatite is less susceptible to acid attacks from bacteria, which are the primary cause of tooth decay.
Real-life examples of fluoride incorporation in dental products include fluoride toothpaste and mouthwash. These products help deliver fluoride directly to the teeth, enhancing its protective effect. Additionally, many communities add fluoride to their public water supplies, known as water fluoridation, providing a cost-effective and widespread approach to improving oral health in populations.
By promoting the formation of more robust tooth enamel, fluoride aids in preventing cavities and maintaining good dental hygiene, contributing to overall oral health and well-being.
