Are Your Teeth Sensitive? Check Your Toothpaste For Hydrated Silica

Dentist Blog

If you have developed tooth sensitivity—especially to hot and cold foods, you'll want to reach out to your dentist for a firm diagnosis. There are numerous causes of tooth sensitivity, such as bruxism, worn fillings, over-bleaching, gum recession/gum disease, etc. If you don't have any serious underlying dental issues, you may want to look at your toothpaste ingredients for hydrated silica. Read on to learn more.

What Is Hydrated Silica, and Why Is it Used in Dental Care?

Hydrated silica is a form of silicon dioxide that's often used in food products as an anticaking agent and in personal care products, like toothpaste, as an abrasive and/or bulking agent.

Hydrated silica can be used in the polishing agents (prophy pastes) in the dental office. After a dentist removes tartar during a cleaning, he or she typically uses a polishing agent on the patient's enamel. Because hydrated silica has a rough texture, it helps to remove surface stains from teeth.

And while hydrated silica is mainly used to improve tooth aesthetics, it can also help to remove plaque and other debris before it has the chance to build up as tartar.

How Can You Fix the Issue with Sensitivity?

As you can see, there are many benefits of hydrated silica, so it isn't inherently bad; but if you have tooth sensitivity, you may want to opt for a toothpaste that doesn't include this ingredient. For instance, many whitening toothpastes contain hydrated silica since it can help remove discoloration, so you may want to try an anti-sensitivity toothpaste or try another bleaching method, like whitening strips, that isn't abrasive. Re-mineralizing toothpaste that contains potassium, fluoride, and calcium can help to reduce sensitivity.

If you like a certain brand of toothpaste but it has hydrated silica, you may want to check its relative dentin abrasively (RDA) score. Some toothpastes contain more of this ingredient, but any toothpaste with a value under 250 is considered safe for daily usage. Also, consider the type of toothbrush you are pairing with the toothpaste. Soft-bristled toothbrushes are better for your teeth than hard-bristled ones since they don't push abrasive ingredients into porous enamel.

If the sensitivity hasn't improved with these changes, you may want to talk to your dentist about fluoride treatments and/or composite resin bonding. Most fluoride preparations can reduce sensitivity. And while composite resin bonding can be used for cosmetic improvements, it can also be used for functional improvements. Composite resin can bulk up the enamel and reduce sensitivity.
