We all know how we dread those dental fillings, and then years later, we have to go back and remove the old and have the tooth filled again by your local dentist in Annandale, VA. With new research at the (Oregon Health and Science University) OHSU School of Dentistry in Portland, Oregon, there has been a new dental filling created by using a filling material that is twice as much resistant to breakage than standard dental fillings, according to a study which was published in the journal Scientific Reports. https://www.nature.com/articles/s41598-019-39003-w This new filling uses a thiourethane additive which is also used in protective coatings for decks and cars.

An adhesive has also been developed by the same team of researchers from OHSU School of Dentistry in Oregon that is thirty percent stronger after six months use than other adhesives that are currently used by Annandale, VA dentists to keep dental fillings in place. This was described in a recently published journal, Dental Materials https://www.sciencedirect.com/science/article/abs/pii/S0109564118311035?via%3Dihub.

The two combined, both the adhesive and the composite, are designed to make dental restorations last longer. Typically, today, dental restorations by local dentists in Annandale, VA last only about ten years; cracking under the pressure of chewing, or gaps form between the tooth and the dental fillings, which allow bacteria to seep in and create a new cavity. Each time this happens, the tooth under the dental filling will become weaker and then what starts as a tiny cavity can end up with root canal damage or a lost tooth, and also quite possible, a life-threatening infection.

What would stronger dental materials mean for Annandale, VA patients? They wouldn’t have to have dental fillings replaced or repaired quite as frequently, and it would save them time and money while also preventing more severe problems that could involve more extensive treatments.

This adhesive that was described in the journal, Dental Materials, uses a specific type of polymer known as (meth)acrylamides. It is considerably more resistant to damage in water, bacteria, and enzymes within the mouth than standard adhesives which are currently used by local Annandale, VA dentists. Thiourethane, the composite material described in Scientific Reports, holds up better to chewing than the standard composites used by dentists in Annandale, VA currently.

Imagine having a composite material that will repair tooth decay. Dentistry research is always trying to improve better ways to preserve our original teeth. A Professor Robert Hill who is Chair of the Physical Sciences at the Institute of Dentistry at Queen Mary University of Loudoun and co-founder and director of research of BioMin Technologies has presented the first data on dental fillings which can actively repair tooth decay.

The data indicates a significant step forward in restorative materials that prolong the life of composite fillings and reduces the need for mercury-based amalgams.

New bioactive glass composites have the ability to release fluoride and significant amounts of calcium and phosphate that are needed to form tooth mineral. The new data on bioactive glass composite fills in the gaps with tooth mineral, which prevents oral bacteria that causes tooth decay to establish themselves. This research in the U.S. suggests that this will prolong the life of dental fillings and slow down secondary tooth decay because of the bacterial penetration depth with bioactive glass fillings is considerably smaller than for inert fillings.

For now, your local dentist in Annandale, VA has several different dental filling methods that you can choose from including—

  • Amalgam fillings (silver) are dark in color and much more noticeable than porcelain or composite restorations. These fillings usually are not used in visible areas such as the front teeth. Amalgam fillings are relatively inexpensive and resistant to wear.
  • Composite resins (plastic) are matched to the same color of your other teeth. These resins are used in areas where a much natural appearance is desired. The ingredients are mixed and then placed into the cavity and allowed to harden. These dental fillings are not recommended for large fillings because they may chip or wear over a period of time. Coffee, tea, and tobacco will also stain these resins, and they usually do not last as long as other fillings.
  • Porcelain fillings are referred to as inlays or onlays depending on what part of the tooth is restored. These fillings are much stronger and more reliable than colored bonding or resin fillings. Porcelain fillings generally cover most of the tooth and are more costly.
