We know the drill: dental fillings are not fun to get. But there is a new reason to be optimistic about the state of filings. A team of researchers created a new dental filling that they report to be twice as strong as traditional fillings. They developed the compound for their new filing by using an ingredient used to manufacture car bumpers and protect outdoor decks.


There is a good chance that when you come to Advanced Smile Care and if you have a  bad cavity, you will likely need a filling. Our doctors will treat the affected area by removing the decayed part of the tooth. Dental fillings are done on patients with cracked, broken or worn down teeth as well. A traditional filling lasts several years but will eventually need to be replaced by a new filing or with a crown. The area will be treated with a material that’s dependent on the severity of the decay. The American Dental Association breaks down the different types of filings:

  1. Composite resins: This material is the most popular one because the color is similar to human teeth. The compound is a mix of glass or quartz filler that is durable. It’s resistant to moderate pressure from daily chewing or movement in the teeth.
  2. Dental Amalgam: It’s known as a silver filling. The material is a combination of mercury, silver, tin and copper. This form of filling is more durable and affordable than composite resins or gold fillings.
  3. Gold Fillings: The material is made up of gold, copper and other metals. The ADA says gold has been used for more than 1,000 years in dentistry. The filling is extremely durable but more expensive.

“We can walk you through all of the options for filings at our office. Our prioirty is to make sure you’re getting a filling that’s right for you and your teeth,” said Dr. Jason Kboudi who heads up the team at Advanced Smile Care.


Researchers from OHSU School of Dentistry in Portland, Oregon have designed a new material which they report to be twice likely to withstand breakage than a standard filling. The researchers say they also developed an adhesive to keep fillings in place which is 30 percent stronger than current adhesive materials. 

The study was published in Scientific Reports and Dental Materials. One of the authors of the study said the new filling will prevent long-term problems and less frequent dentist visits.

“They crack under the pressure of chewing, or have gaps form between the filling and the tooth, which allow bacteria to seep in and a new cavity to form,” said Carmem Pfeifer, D.D.S., Ph.D on OHSU.edu. “Every time this happens, the tooth under the restorations becomes weaker and weaker, and what starts as a small cavity may end up with root canal damage, a lost tooth or even life-threatening infections.”
