Ancient Fillings (Prehistoric to Early Civilizations):
- Around 6500 years ago, beeswax was used as a filling material,
as seen in remains from Italy and the Indus Valley Civilization.
- Early civilizations also experimented with natural resins and
tar, but these materials were not durable and often failed to prevent further
decay.
- In China, as early as 700 AD, a “silver paste” (early amalgam)
was referenced in medical texts.
- Other materials like cork, tin, and even asbestos were used sporadically, though with limited success.
Early Modern Period (1700s–1800s):
- The 1700s saw the introduction of tooth-colored options, with
attempts to use enamel and porcelain fused to gold for better aesthetics.
- Gold, platinum, silver, tin, and lead were all used as filling
materials in the early 1800s, with tin being a popular, affordable option.
- In the 1830s, the development of dental amalgam (a mix of mercury and metals like silver, tin, and copper) revolutionized fillings due to its ease of use and low cost, despite controversy over mercury content.
Modern Era (1900s–Present):- Throughout the 19th and early 20th centuries, metal and
amalgam fillings dominated, with porcelain and gold also used for their
durability and aesthetics.
- The mid-20th century introduced composite resin fillings (plastic and glass mixtures), which could be color-matched to teeth and required less removal of healthy tooth structure.
- Ceramic (porcelain) fillings emerged, offering both strength and a natural appearance.
- Today, the most common filling materials are:
- Composite resins (tooth-colored, aesthetic, conservative)
- Dental amalgam (durable, cost-effective, still used but less
popular due to mercury concerns)
- Gold (highly durable, expensive, less common)
- Ceramic/porcelain (aesthetic, durable, more costly).
