Are tooth-colored fillings safer than silver fillings?
No. Both are considered safe based on the most reliable and up-to-date scientific evidence. Still, tooth-colored fillings do have some definite advantages. Not only do they blend in with your smile far better than “silver” (dental amalgam) fillings, but they often require less removal of healthy tooth structure. That’s because in order to fill a tooth with amalgam, it is necessary to create indentations in the tooth called “undercuts” to hold the amalgam in; this requires the removal of some healthy tooth material. With a tooth-colored filling, we need only remove the decayed part of the tooth to place the filling.
Are there any disadvantages?
Yes, tooth-colored fillings don’t always wear as well as metal fillings — particularly on back molars where they are subjected to the most stress from chewing. They are also more expensive and less likely to be fully reimbursed under dental insurance plans.
Are there different types of tooth-colored fillings?
Yes, three different choices of tooth-colored fillings are available:
- Composite — This mixture of plastic and glass is the most common type of tooth-colored filling. Newer materials can hold up almost as long as amalgam fillings and look very natural, though they can stain over time just as natural teeth do.
- Porcelain — High-tech dental ceramics are considered the most aesthetic choice of filling material. They don’t stain as composites can, but their relatively high glass content can make them more brittle and prone to breakage. They may be more expensive than composites.
- Glass Ionomer — Made of acrylic and glass powders, these inexpensive, translucent fillings blend in acceptably well with natural teeth and have the advantage of releasing small amounts of fluoride to help prevent decay. However, they generally don’t last as long as other restorative materials.
We would be happy to offer guidance on which choice would be best in your own unique situation.

Supermodel Christie Brinkley has a one-in-a-million smile, but she is just one of millions who have benefited from today's preferred tooth-replacement technique: the dental implant. In a wide-ranging interview, Brinkley told Dear Doctor magazine about a helicopter accident she suffered while back-country skiing.
“I fractured two molars in the back of my mouth and I had to get two dental implants,” Brinkley told the magazine. “I am grateful for the dental implant technology that feels and looks so natural.”
You might think it serves little purpose to replace a missing back tooth that was barely visible in your smile to begin with — especially if you don't spend a lot of time posing for magazine covers. But this is actually not the case. Your molars are extremely important for chewing and even for maintaining a more youthful appearance.
Dentists generally agree that losing posterior (back) teeth can have many consequences for the remaining teeth and their surrounding structures, i.e., bone and gums. If back teeth are missing, the front teeth end up bearing more stress than they were built for. And there are certain things that happen when any tooth is lost, whether front or back, that can affect function and appearance.
For one thing, when a tooth is lost the adjacent teeth tend to drift into the empty space or tip towards it. This can adversely affect your bite. Too much shifting can render a tooth basically useless and also leave it more vulnerable to gum disease.
Another complication is the loss of tooth-supporting bone that inevitably occurs when teeth are lost. When a tooth comes out, the bone under it actually begins to melt away. Since back teeth support the vertical dimension of the face, their loss can cause what's known as “bite collapse” — a reduction in facial height that becomes increasingly noticeable over time and can make you look older.
A dental implant can prevent all of these things, while providing you with a replacement that looks and feels just like the tooth you lost.
