Adding fluoride to public water supplies to prevent tooth decay.

Fluoride reduces cavities, especially in children's teeth.

1ppm (parts per million) of fluoride in water is linked to most effective decay reduction.

Tooth discoloration and/or staining caused by high fluoride levels during tooth development.

A 1985 report that found no link between fluoride and cancer.

A study that reviewed evidence and concluded fluoride in water was safe.

Approximately only 10% of the UK population currently has fluoride in their drinking water.

A review of various studies that further confirmed fluoride's role in preventing tooth decay.

Fluoride helps prevent cavities by incorporating into tooth enamel, making it more resistant to acid attacks caused by bacteria.

Fluoride is absorbed into the tooth during two stages: systemic (swallowed fluoride) and topical (applied directly).

Fluoride absorbed from systemic sources during tooth development is incorporated into the enamel, making it stronger.

After teeth erupt, topical fluoride application strengthens the enamel by replacing some of the hydroxyapatite with fluorapatite.

Fluoride travels from systemic sources to developing teeth via blood and tissue fluid, replacing hydroxyapatite with fluorapatite during enamel formation.

After enamel calcification and before eruption, fluoride continues to be deposited on the enamel surface from surrounding tissue fluid, further strengthening the enamel.

Excessive fluoride intake during tooth development can inhibit ameloblast activity, leading to enamel defects called fluorosis, which may cause discoloration.

Fluorapatite is a more resistant form of enamel compared to hydroxyapatite, making teeth less prone to decay.

Fluoride is an essential element that plays a key role in strengthening tooth enamel and preventing cavities.

The period after a tooth erupts and emerges into the mouth, where it's susceptible to demineralization and remineralization processes.

The process where tooth enamel loses calcium and phosphate, making it weaker and more prone to cavities.

Acids produced by bacteria in the mouth that attack enamel and cause demineralization.

The main mineral component of tooth enamel, responsible for its hardness and resistance to decay.

The process where calcium and phosphate from saliva are deposited back into the tooth enamel, repairing weakened areas.

Fluoride in saliva helps strengthen enamel by incorporating itself into the tooth structure, making it more resistant to acid attacks.

A stronger and more decay-resistant form of hydroxyapatite formed when fluoride replaces some of the hydroxide ions in enamel.

A decrease in the pH level of the mouth due to bacterial acid production, creating an acidic environment that favors demineralization.

Saliva plays a crucial role in remineralization by providing calcium, phosphate, and fluoride, helping to repair damaged enamel and protect teeth.

Tooth enamel is not static; it's constantly undergoing demineralization and remineralization processes, influenced by factors like diet, oral hygiene, and fluoride exposure.

Fluoride reduces the ability of enamel to absorb proteins, which in turn decreases the ability of bacteria to adhere to the surface of the tooth.

Fluoride decreases pellicle formation, which is a thin film that bacteria use to attach to teeth. This leads to less bacterial adhesion, therefore reducing plaque buildup.

Fluoride can influence tooth development, potentially resulting in shallower pits, reduced fissure depth, and lower cusp height, making teeth easier to clean.

Fluoride incorporates into the root surface during remineralization, reduces surface wettability, and has antibacterial effects, protecting against root caries.

Patients with xerostomia (dry mouth) and those who have undergone radiotherapy are more prone to root caries due to reduced saliva production and compromised oral hygiene.

Root caries is tooth decay that affects the exposed root surface, primarily affecting individuals with gingival recession.

Flourde helps remineralize teeth by incorporating into the tooth surface, making the enamel stronger and more resistant to decay.

The majority of fluoride uptake occurs during the two to three years after a tooth emerges, due to the enamel's porous nature, facilitating fluoride absorption.

Newly erupted teeth have more porous enamel, making them more susceptible to demineralization but also allowing higher fluoride uptake.

Topical fluoride reacts with calcium, forming a protective layer on the tooth surface rather than penetrating deeply. This layer releases fluoride during acid attacks, aiding remineralization.

Fluorapatite is a modified form of enamel formed when fluoride replaces hydroxyl ions during remineralization. It's more resistant to acid attacks than hydroxyapatite.

Fluorapatite has a lower critical pH compared to hydroxyapatite, making it more resistant to acid attacks and less likely to dissolve.

Topical fluoride applications create a reservoir of fluoride in saliva. This fluoride binds to calcium in saliva, forming CaF2, which is released during acid attacks.

Maintaining a regular supply of fluoride helps replace lost ions and promotes enamel remineralization, effectively reducing caries risk.

Toothpaste, mouth rinses, and some restorative materials provide different levels of fluoride, offering various options for optimal protection.

Prescription fluoride is primarily recommended for individuals with high caries risk or when using toothpastes with higher fluoride concentrations (2800 or 5000 ppm).
