Tooth Paste

Toothpaste, also known as dentifrice, is available in paste, gel, or powder form. Despite the many types of toothpaste that exist, there are some ingredients common to most varieties. These include:

· Abrasive agents. Scratchy materials, including calcium carbonate and silicates, help remove food, bacteria, and some stains from your teeth.

· Flavoring. Artificial sweeteners, including saccharin, are often added to toothpaste to make them taste better. While many people equate the flavor of toothpaste with mint, toothpaste is available in a variety of flavors, including cinnamon, lemon-lime, and even bubblegum (for kids -- or kids at heart).

· Humectants for moisture retention. Paste and gel formulations often contain substances like glycerol to prevent the toothpaste from drying out.

· Thickeners. Agents that add thickness to the toothpaste, including gums and gooey molecules found in some seaweeds, help achieve and maintain proper toothpaste texture.

· Detergents. Those suds you see when you brush your teeth are from detergents like sodium lauryl sulfate.

· Fluoride toothpaste(sodium monoflourophospahtes)

· The most important ingredient to look for when choosing toothpaste is fluoride.

· Fluoride is a naturally occurring mineral. Its use has been instrumental in the dramatic drop in tooth decay and cavity occurrence that has taken place over the past 50 years. Bacteria in your mouth feed on sugars and starches that remain on your teeth after eating. Fluoride helps protect your teeth from the acid that is released when this happens. It does this in two ways. First, fluoride makes your tooth enamel stronger and less likely to suffer acid damage. Second, it can reverse the early stages of acid damage by remineralizing areas that have started to decay.

· Using fluoride toothpaste is an important way to ensure that your teeth are reaping the benefits of this dental-friendly mineral. Don't think you can skip fluoride if you live in an area where the water is fluoridated. Studies have shown that using fluoride toothpaste helps increase the concentration of fluoride in the teeth, even in areas with water supplies containing high levels of the mineral.

· Tartar control toothpaste

· There are many tartar control toothpastes on the market, most of which contain fluoride.

· Everyone has a layer of bacteria on their teeth called plaque. If plaque isn't removed promptly with proper oral hygiene, it hardens into tartar. This hard-to-remove deposit can build up on your teeth and under your gums, ultimately leading to gum diseases.

· There are a variety of ingredients used in toothpaste to help prevent the accumulation of tartar on the teeth. Chemical compounds, including pyrophosphates and zinc citrate, are often added and have been proven effective. Additionally, some tartar control toothpastes contain an antibiotic called triclosan, which kills some of the bacteria in the mouth.

· Certain toothpastes containing multiple anti-plaque agents in one formulation have been demonstrated to be even more effective at tartar control than varieties with only one plaque fighter

Toothpastes for sensitive teeth

For people who have teeth that are easily irritated -- for instance, by hot or cold temperatures -- there are toothpastes available that are specially formulated for sensitive teeth. These toothpastes usually contain potassium nitrate or strontium chloride. These chemical compounds, which can take up to four weeks to offer relief, reduce tooth sensitivity by blocking pathways through the teeth that attach to nerves.

Whitening toothpaste

To help people on a quest for pearly whites, many whitening toothpastes are now being marketed for everyday use.

Whitening toothpastes do not typically contain bleaches. Instead, they contain abrasive particles or chemicals that effectively polish the teeth or bind to stains and help pull them off the tooth surface.

Although you might be concerned that the abrasiveness of whitening toothpaste could damage your teeth, studies suggest that whitening toothpastes are no harder on tooth enamel than other types of toothpaste.
