Just the number of options you have when you buy a tube of toothpaste can be overwhelming. Should you go for tartar control? Fluoride? Both? And don't forget to think about whitening toothpastes or formulas with all natural ingredients.

When it comes to choosing the best toothpaste for you, it's important to think about your unique oral health needs.

Toothpaste basics

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

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.
