Question: What components of cheese helps prevent tooth decy?
About the article "Cheese", section "Dental health".

Candidate passages:
Some studies claim that cheddar, mozzarella, Swiss and American cheeses can help to prevent tooth decay.
Several mechanisms for this protection have been proposed:
 The calcium, protein, and phosphorus in cheese may act to protect tooth enamel.
 Cheese increases saliva flow, washing away acids and sugars.
Soft cheeses require a "sharp" knife.
As these cheeses are often sticky, a cheese knife will be serrated and often have holes to prevent sticking.
Soft cheese knives are designed to deal with the stickiness of soft cheese.
When the cheese does not stick to the blade, it allows for pieces of cheese to be presented more attractively, with crisper shapes compared to cheese cut with standard knives.
The blades of cheese knives are usually made of a material, such as stainless steel, which is resistant to the stickiness of cheese.
Another design feature often found is the presence of holes in the blade to help to prevent the cheese from sticking to it.
Some soft cheese knives also include a ridge, which runs vertically near the top of the blade.
This helps separate the cheese as it is being sliced.
Some cheese knives have a forked end and is used for serving slices of cheese.
Furthermore, the shape is unusual.
Most knives have a blade that is wide at the base and tapers to the tip.
A cheese knife, on the other hand, is similar to a cleaver in that it starts out thinner at the handle and then gets wider away from the base.
Some cheese knives have angled handles to make an easier cut.
The non-sticky characteristics of a cheese knife also makes them useful for cutting other sticky foods, such as cakes, eggs, and pies; compare also egg slicer. 
Whey is a by-product of cheese production.
It is one of the components that separates from milk. 
Potions are used to imbue a certain type of cheese into another type of cheese.
For example, imbuing brie cheese with a Radioactive Blue Cheese curd potion would convert the brie cheese into Radioactive Blue cheese.
The number of cheese that can be imbued per potion increases based on the rank of the player.
The Developers have mentioned that in the future, potions may be used to upgrade trap components. 
Gingival recession and cervical tooth wear can be avoided by healthy dietary and oral hygiene practices.
By using a non-traumatic toothbrushing technique (i.e.
a recommended technique such as the modified Bass technique rather than indiscriminately brushing the teeth and gums in a rough scrubbing motion) will help prevent receding gums and tooth wear around the cervical margin of teeth.
Non-abrasive toothpaste should be used, and brushing should be carried out no more than twice per day for two minutes on each occasion.
Excessive use of acidic conditions around the teeth should be avoided by limiting consumption of acidic foods and drinks, and seeking medical treatment for any cause of regurgitation/reflux of stomach acid.
Importantly, the teeth should not be brushed immediately after acidic foods or drinks.
A non-abrasive diet will also help to prevent tooth wear.
Flossing each day also helps to prevent gum recession caused by gum disease.
