After you eat sugar, glycoproteins and the bacteria S. mutans attach to teeth and begin forming plaque. The bacteria produce lactic acid, which increases the dissolving of calcium phosphate in the enamel. The S. mutans bacteria is the only type that can cause cavities, because it is the only one with the enzyme that adds glucose molecules to each other to form dextran.The dextran and bacteria cling to the enamel, which creates plaque, the first stage of the formation of cavities.

What ingredients in toothpaste whiten your teeth?

# data[].attributes.body
The ingredients carbamide peroxide and hydrogen peroxide whiten your teeth. The process of whitening your teeth is a chemical process called tooth bleaching. Some toothpastes contain hydrogen peroxide directly, and in others the carbamide peroxide reacts with the water to release hydrogen peroxide. While you brush your teeth, the hydrogen peroxide oxidizes the organic composites in your tooth enamel, which creates smaller, lighter colored composites, resulting in whiter teeth.

Fluoride is mostly beneficial for teeth. It strengthens teeth by hardening the enamel, which helps prevent tooth decay. However, too much fluoride can cause a condition called dental fluorosis. This condition causes teeth to have white spots, become rough and pitted, or even have extreme discoloration of brown spots on teeth. Doctors recommend around 10 mg of fluoride a day, and say that if your drinking water and toothpaste have fluoride in them, then you have the perfect amount going into your body.

The major science concept discussed in this article is the chemical composition of toothpaste and your teeth. The article talks about what the enamel of teeth is composed of, and how it is broken apart. The ions in enamel can be broken apart by a chemical imbalance that is a result of harmful bacteria. After introducing this topic, the article goes on to explain the chemical composition of toothpaste and how it combats the break down of enamel. The discussion of the different ions and acids in enamel and toothpaste relates to chemistry, because in chemistry we learn about how elements bond together and react together.

4. What ingredients in toothpaste whiten your teeth?

5.  How do bacteria destroy our enamel?

# data[].attributes.body
1. Bacteria produce acids that dissolve the enamel on our teeth in a process called demineralization.

2. Many toothpastes contain the fluoride compounds sodium fluoride, sodium monofluorophosphate, or tin fluoride in order to prevent tooth decay and restore teeth after previous damage.

3. Biofilms are formed when multiple bacteria stick to a damp surface and create a slimy substance.

4. Hydroxyapatite is the substance that makes up enamel and it is made up of positive calcium ions, negative phosphate ions, and hydroxide ions.

5. Abrasion is the process of scrubbing off bacteria and keeping it from making biofilms on your teeth, and many toothpastes contain abrasives like baking soda to do this.
