White fillings are made of composite materials and people are asking their dentists for the options of white instead of silver. The white fillings look like a regular tooth. It is between you and your dentist, because no one else will be able to tell if you had a cavity filled or not. The look is significantly better than the unsightly, obvious, silver fillings, but are they strong enough? Also, how does the material adhere to your tooth? According to one of the top dentists at Rockwest Dental, dental material manufacturers go through vigorous mechanical property testing to determine the durability of their materials. They would not put out a product that would not hold up and furthermore reputable dentists would never use a product that wasn’t going to last.
Dental materials ranging from composite resin fillings, to porcelain to metal crowns and bridges, to alginate impression material, to dental adhesives for bonding and restorative dentistry are all tested for their mechanical property strengths. ISO 6872, ISO11405, ISO14801, ISO 9917, and other standards specify the requirements and the corresponding test methods to access dental materials.
