Can new Nanocomposite Fillings Strengthen your Teeth?

The mouth is a place where bacteria thrive and have the potential to combine with food and cause cavities. For this and other reasons dentists do not offer a guarantee on the dental work they perform.

Recurrent decay is out of their control. In fact, it’s well known that teeth will eventually crack from the hot, cold and pressure of chewing and biting. It is not uncommon for recurrent tooth decay to form in the cracks of teeth where fillings have been placed. Nanocomposites may just be the next step to an address this problem.

Dental Filling Replacements

70 percent of all dental procedures will need to be replaced over time. This means that existing fillings may need to be replaced with dental crowns and other procedures to stop tooth decay and restore the tooth. The costs to Americans totals $5 billion every year. However, science now believes it may have the answer to this problem. Nanocomposite fillings, which are made of calcium phosphate, can release agents that fight tooth decay. When released, these calcium agents work against the acid that bacteria produce. This revolutionary creation helps teeth replace minerals that were lost as a result of cavities and other dental problems. Teeth are repaired when ions are released into the area of the tooth that lacks minerals and is beginning the decay process.

The Value of Nanocomposite Fillings

Scientists at the American Dental Association’s Research Center believe that nanocomposites have the ability to decrease the number of dental procedures that patients must undergo. Nanocomposites are much stronger than traditional fillings and are less prone to breakage. The ions produced by nanocomposite fillings are important because they distribute there calcium ions to other fillings on a regular basis. In other words, the new fillings help strengthen the older fillings.

Ion-releasing Compounds

Scientists have developed a spray-drying method that distributes several compounds that naturally strengthen tooth enamel and rebuild lost tooth tissue. These spray-drying compounds contain agents such as dicalcium phosphate anhydrous or DCPA. The size of a DCPA is 50 microns in length. Nanoscale particles have a high surface volume so they can easily distribute ions to enhance tooth health.


The ultra small particles in nanocomposites can be polished to an extremely high shine. The level of this shine is a close match to natural tooth structure. This makes for improved appearance of these filling so critical in the front teeth.  If fact they frequently are invisible and help dentists to create the perfect smile.

Tip of the Day: If you see any bleeding when you brush and floss you have a problem. Many people believe that a little bleeding is ok. Not so. Normal healthy gums do not bleed at all. If you see blood it is time to see your dentist. Don’t delay as dental problems have a way of getting worse rapidly.
