Ever wonder what the old “silver” fillings or “amalgam” fillings look after a few years in the mouth? Here is a good picture! Maybe they should be called “black fillings!”
Silver fillings were created decades ago to allow dentist to fix teeth that were decayed. And while a lot of scientific findings were used to create the filling material, they leave a lot to be desired by today’s standards.
Silver fillings have been placed for a long time (and still continue to be placed in some dental offices and clinics). However, they do pose several major problems. First of all, they look like crap after a few years of service. This is obvious to anyone, not just dentists. They leak and stain the tooth structure around them. Looking at the photo above you can see the gray shadows that’s spreading out from the filling inside the tooth. They cause teeth to break prematurely. Because of their metallic nature, they expand and contract differently than enamel and dentin when exposed to high and low temperatures. Because of this difference in expansion and contraction rate, they place a lot of unnecessary forces on the tooth. Looking at the photo above you can see 2 fracture lines starting on the left side. Oh, and one last minor detail is that they contain mercury. No biggie though!
This is the same tooth after the silver filling and fracture lines were removed and replaced with a white filling. White fillings are not just more esthetic and pretty. They resemble the tooth structure they are replacing making teeth less likely to fracture. Also, these white fillings are bonded to the teeth chemically. This helps solidify the tooth as a unit, instead of having something lodged in the center of the tooth causing it to split over time. These white fillings are also easier to repair and maintain compared to a silver filling.
The next time you are given a choice between a silver filling and a white filling, you’ll be better prepared to choose the white filling knowing it is a better material which not only looks better, but is better for the health of the tooth. At Platinum Dental, Inc. we only use white fillings when a filling is necessary. Follow this link to learn more about white fillings.
