Does Colgate contain hydrated silica?
The commercially available dentifrice (Colgate Total Toothpaste) contains 0.3% triclosan and 2.0% PVM/MA copolymer in a 0.243% sodium fluoride/silica base. The new formulation variant contains those same ingredients, of which 10% of the silica is a high cleaning grade (Colgate Total Plus Whitening Toothpaste).
Is hydrated silica bad for your teeth?
Abrasive ingredients Why it’s harmful: Toothpaste only needs to be mildly abrasive to be effective. Some of the abrasives used, such as hydrated silica, are too rough. These ingredients can strip away the enamel and dentin, creating sensitivity and leading to gum recession.
Does Crest toothpaste have silica in it?
Crest toothpastes are formulated with hydrated silica, a mild abrasive that ensures you get an effective, yet gentle clean with whitening benefits by removing surface stains.
Where is hydrated silica found?
Hydrated silica is a form of silicon dioxide, which has a variable amount of water in the formula. When dissolved in water it is usually known as silicic acid. It is found in nature, as opal (which has been mined as a gemstone for centuries), and in the cell walls of diatoms.
What toothpaste is bad for enamel?
Be sure to avoid any toothpastes that contain activated charcoal. Too often, unregulated toothpastes containing extremely harsh particles end up causing serious enamel damage and permanent discoloration.
Is Sensodyne Pronamel safe?

Why is Crest toothpaste bad?
Crest uses hydrated silica beads in some products, and polyethylene plastic beads in other products. Some people want an abrasive toothpaste to help clean the teeth, but the plastic beads are more abrasive than a toothpaste needs to be.
What does hydrated silica look like?
Silica is crystalline as it occurs in nature. Sand and obsidian are common forms. The liquid sodium silicate is mixed with acid and precipitated to make hydrated silica, which is an odorless, tasteless white powder.
What is hydrated silica made of?
Hydrated silica is naturally derived from silica (silicon dioxide), an abundant compound that forms about 12 percent of the earth’s surface.
What is hydrated silica, and how is it made?
Silica is crystalline as it occurs in nature. Sand and obsidian are common forms. The sand is heated with sodium carbonate and dissolved in water to form liquid sodium silicate. The liquid sodium silicate is mixed with acid and precipitated to make hydrated silica, which is an odorless, tasteless white powder. The hydrated silica is then milled in the U.S., and based on the particle size of the material, can be used for a variety of different applications.
Is silica safe in toothpaste?
Silica Gel (Hydrated Silica) is a high performance abrasive that is most commonly used in toothpastes, because it appears to be the safest and most effective abrasive available.
Is hydrated silica dangerous?
In chemistry, hydrated silica is sometimes referred to as an inert substance, meaning it is not chemically reactive. This substance is not known to be toxic, or cause cancer, and the Food and Drug Administration (FDA) in the United States has classified it as Generally Recognized As Safe (GRAS).
Why silica is suitable for toothpaste abrasive?
Besides aiding in the removal of plaque and food particles, abrasives like hydrated silica can also help to remove stains, which makes them useful as whitening agents in toothpastes as well. Abrasives used in toothpaste date back over 2000 years, where paste mixtures were once made with bones and ground shells.
