If you have a decayed tooth, you might feel tempted to opt for a less costly amalgam (metal) filling. It’s the tried-and-true material that has historically been used for dental work like repairing cavities. Today, however, most dentists rely on tooth-colored materials for the same fixes. Continue reading to learn 4 reasons why you might want to opt for the upgraded option when it comes to restoring your teeth!
Reason #1: Look & Feel
One of the common complaints about metal fillings is that they can be easily seen because of their dark grey color. Anytime you open your mouth to speak or smile, it can catch the light and draw immediate attention to itself. Composite resin, however, can be customized to match the shade of your pearly whites for a completely seamless smile.
Reason #2: Bonding Techniques
The reason that metallic alloys were used in the past is because they are strong enough to protect your damaged tooth from additional harm. Unfortunately, though, the materials don’t bond with the organic composition of your teeth. Instead, they’re held in place by a technique known as ‘retention’, which involves placing an undercut for the metal to lock into. Because this further degrades the underlying structure of your already damaged tooth, it can eventually fracture even further.
Composite resin fillings, meanwhile, are made of resources that bond to your enamel directly so more of the natural build of your tooth is preserved. This makes them a reliable, long-lasting solution.
Reason #3: Toxicity
Many patients don’t realize that the metal compounds used to fix their smiles usually contained 50% mercury which is toxic to humans. When it’s installed in your mouth, you swallow and inhale bits of the vapor regularly. It can be particularly dangerous for those who are pregnant, for children, and for those with other medical conditions like Parkinson’s or Alzheimer’s, impaired kidney function, or heightened sensitivity to the ingredient.
Thankfully, composite resin fillings are generally considered non-toxic and safe to use in your mouth.
Reason #4: Temperature Changes
Another drawback of amalgam fillings is that metal is a great conductor of temperature. That means if you’re eating something incredibly hot or cold, it can travel through the filling and be felt in the root of your vulnerable tooth. This can cause quite a bit of sensitivity and discomfort. Tooth-colored fillings don’t have this problem because they don’t resonate with temperature changes.
If you have a cavity that needs to be filled, using tooth-colored materials can benefit you in the long run!
