Gold is used in dentistry because it is less reactive in the mouth, and is durable, appealing and gentle on opposing teeth, according to Dr. Martha Rich. Gold is preferred for teeth filling due to its strength in withstanding chewing forces and its ability to last 15 to 30 years.
Due to its toughness and durability, gold is desirable for replacing teeth that have reoccurring issues and for patients who grind habitually. Gold teeth eliminate issues of tingling pain or chipped teeth, which are common with comparable dental crown materials, claims Dr. Chetan Bhawani. Finally, a thin layer of gold guarantees a healthier tooth structure, notes Dr. Martha Rich.
