Is alkaline good for teeth?
Alkaline water has a basic pH, 100 times more alkaline than spring water. The basicity of the alkaline water neutralizes the acid produced by bacteria, promoting stronger teeth and bones. Alkaline water also stimulates saliva production, which also helps rid the mouth of excess bacteria.
Is alkalinity bad for teeth?
It has long been known that acids can erode tooth enamel but a new Swedish study shows that strong alkaline substances can damage teeth too — substances with high pH values can destroy parts of the organic content of the tooth, leaving the enamel more vulnerable.
What pH do Teeth start decaying?
A pH of 7 is neutral – the pH of pure water is very close to 7. At a pH of 5.5 the teeth begin to demineralize, putting them at risk for cavities.
How can alkaline toothpaste reduce tooth decay?
Our mouths contain bacteria (細菌). These bacteria can change the sugar left on our teeth into acids. These acids then dissolve our teeth and cause tooth decay (蛀牙). However, if we brush our teeth with toothpaste, the alkaline in the toothpaste will neutralise the acids produced by the bacteria in our mouth.
What chemical reaction happens when you brush your teeth?
Calcium phosphate and hydrogen ions undergo a reversible reaction with calcium ions, phosphoric acid and water. The products of the reaction are calcium ions, phosphoric acid and water. All of these exist in chemical equilibrium with the crystalline calcium phosphate.
Is tooth decay a chemical reaction?
Tooth enamel is a highly mineralized acellular tissue, and caries act upon it through a chemical process brought on by the acidic environment produced by bacteria. As the bacteria consume the sugar and use it for their own energy, they produce lactic acid.
How do you reverse tooth decay?
Fortunately, the beginning stages of a cavity can be reversed by taking steps toward good oral hygiene. During early demineralization, exposure to fluoride, daily brushing and flossing, and regular cleanings can all help prevent — or even reverse — tooth decay.
Does lack of saliva cause tooth decay?
If you don’t have enough saliva and develop dry mouth, this can lead to: Increased plaque, tooth decay and gum disease.
Can teeth decay?
Cavities are permanently damaged areas in the hard surface of your teeth that develop into tiny openings or holes. Cavities, also called tooth decay or caries, are caused by a combination of factors, including bacteria in your mouth, frequent snacking, sipping sugary drinks and not cleaning your teeth well.
What is the leading cause of tooth decay?
Major causes of tooth decay are sugary, sticky foods and beverages. The more sugar consumed, the more acid, which gets produced leading to decay. Sugar combines with plaque to weaken the enamel leaving you vulnerable to tooth decay.
Can vitamin D deficiency effect teeth?
Numerous studies have shown that vitamin D deficiency also increases the risk of dental decay. This is because vitamin D helps the body absorb calcium and phosphate — both of which are crucial for building and keeping strong tooth enamel.
When is it too late to fix cavities?
Once bacteria have entered your tooth, it may be too late for a filling because we will need to prevent or treat an existing infection. However, it’s never too late for dental care!
