Sugars that bacteria can use to produce acid, leading to tooth decay (caries).

The acidity level at which tooth enamel and dentin start to lose minerals.

Tooth decay caused by bacteria metabolizing fermentable carbohydrates to produce acids.

The loss of minerals from tooth enamel and dentin caused by acid.

The pH level (around 5.5) at which enamel begins to demineralize.

The pH level (around 6.5) at which dentin begins to demineralize.

A reaction that creates acid, which causes the tooth surface to dissolve.

The process where teeth can regain lost minerals, stopping the dissolving process.

A localized chemical breakdown of tooth surface caused by bacteria metabolizing sugars in plaque.

The study of the causes of dental caries.

Factors leading to dental caries: Bacteria, Fermentable Carbohydrates, Tooth Surface, Host Factors.

A sticky film of bacteria living on teeth.

Sugars that bacteria in plaque easily metabolize.

The exterior part of a tooth, including enamel, dentin, and cementum.

Personal factors like saliva quality and immune system that affect caries risk.

The progressive breakdown of tooth structure by bacteria.

Dental caries that can be repaired or halted in its early stages.

Dental caries that worsen over time, eventually causing more issues.

The process where chemicals, often involving microbes and their metabolic byproducts, break down hard dental tissues.

The cause of dental caries, involving susceptible tooth surface, plaque bacteria, time, and fermentable carbohydrates.

Areas of the tooth more prone to dental caries due to factors like plaque accumulation.

The bacteria that contribute to the chemical process of tooth decay.

Sugars that bacteria use to produce acids, leading to tooth decay.

Sugars present naturally in fruits and vegetables, packaged inside cells.

Free sugars not enclosed in cells, readily available for bacteria.

The breakdown of teeth that happens in specific areas, often caused by bacteria and their products.

Potential to cause tooth decay.

A sticky layer of bacteria that accumulates on teeth, providing a breeding ground for decay-causing bacteria.

Table sugar, glucose, and fructose are examples.

Cavities or tooth decay, caused by the interaction of specific factors.

Variations in the tooth's ability to resist decay, related to plaque build-up.

Sugars in fruit, vegetables locked within the cells

Less likely to cause cavities than extrinsic sugars because process of being released and available to metabolise takes time.

A specific type of chemical erosion of tooth enamel caused by bacteria's metabolic activity on fermentable sugars, over time, in a vulnerable spot.

Highly cariogenic because they are immediately available to bacteria which metabolize to produce acid.

Areas on teeth where the restoration (filling) is not properly sealed, creating spaces for food and bacteria to accumulate.

Small grooves or pits in the tooth surface.

Areas on the tooth surface with grooves attracting food and plaque.

Sugars that bacteria use to produce acids, leading to tooth decay.

A sticky film of bacteria that forms on teeth.

Types of carbohydrates that oral bacteria use to produce acid.

A type of sugar that bacteria readily metabolize, forming plaque acids faster than other sugars.

Carbohydrates (like starch) that are not easily broken down by bacteria in the mouth.

Sugars naturally occurring in foods.

Added sugars in processed foods.
