What You Need to Know about Amalgam and Porcelain - Pine Street Dental Blog

Crowns are the best restorative option when decay has been removed, or a tooth has received root canal therapy. Amalgam material, which is a mix of various metals, has been used to repair decay for over a century. Although introduced recently in the world of dentistry, porcelain materials are an improvement over their metal counterparts and offer patients a better crown experience. Porcelain crowns are superior in durability and aesthetics, two key facets in teeth restoration. 


Patients need crowns to last for years, otherwise, they are not cost effective. They must resist wear and tear, and be able to withstand the pressures of daily use. Amalgam fillings do have the potential to last for years, but metal does not bond ideally with teeth. The metal material can be shaped and molded, though it has been known to separate from teeth over time. Little cracks turn larger, which allows an infection to enter inner teeth structures. The mix of metals sometimes includes mercury, which is known to be toxic and is released in small amounts after years of crown wear. Porcelain, on the other hand, is always safe for the smile, designed to fuse with natural enamel, and provides a dental function that nearly matches that of real teeth. Cutting edge crowns are made from porcelain, while others are made from zirconia materials, which are even more durable. All teeth can be repaired with porcelain crowns, and even replace teeth atop dental implants. 


Porcelain mimics the sheen and appearance of teeth, which allows them to blend into the smile. When they are properly shaded you cannot tell them apart from surrounding teeth. They are resistant to teeth staining and require the same amount of oral hygiene care as real teeth. Amalgam fillings are silver in appearance and do not enhance the look of teeth. They do retain their shape throughout their use but can be damaged since the metal is soft. When mercury is used in these fillings, the chewing action releases the toxic particles. After many years of use, amalgam fillings accumulate stains and other imperfections that impact the smile’s aesthetics.
