Repairing a cavity-stricken tooth can be done in one of two ways: a tooth-colored filling or a traditional amalgam. In the past, the latter remained the only option, leaving patients with visible dental work for others to see. However, advancements in the field enable dentists to offer an alternative, more aesthetically pleasing solution. Keep reading to discover 5 reasons why tooth-colored fillings are better than their traditional counterparts.

They Blend With Your Tooth Enamel

Tooth-colored fillings are made of composite resin, a malleable, color-matching material that blends with your existing enamel. Instead of worrying about what others see, they will never know you received dental work because your filling will be virtually invisible.

They Allow You to Keep More of Your Natural Tooth

Composite resin fillings do not contain metal, so less drilling is required. As a result, you can keep more of your natural tooth, reducing the potential need for a dental crown in the future to address cracking and breaking.

They Will Not Expand Over Time

Traditional amalgam fillings can expand and contract over time when exposed to hot and cold temperatures. This can lead to tooth breakage, which requires a dental crown or tooth extraction to address. However, composite resin doesn’t expand, so you never have to worry about it damaging your teeth. Instead, it will preserve as much of the existing structure as possible.

They Are Safer Than Amalgam Fillings

Tooth-colored fillings do not contain mercury, which has been shown to be highly toxic when used frequently as a restorative treatment. For decades, dentists relied on this material to repair decayed teeth, but when mercury vapors are inhaled over time, it can cause problems throughout the body.

Tooth-colored fillings are considered a much safer option for patients.

They Are Suitable for Patients with Metal Allergies

Certain individuals struggle to receive essential dental work because of the metal that is used in various treatment methods. However, tooth-colored fillings contain no metal, so allergies are no longer a concern. Instead, you can comfortably and confidently take proper care of your smile, knowing that nothing will react poorly once it is in place.

Tooth-colored fillings remain a popular restorative option among dentists and patients alike. Instead of reaching for highly visible, toxic, and unsightly amalgam, let your dentist improve your smile and oral health with color-matched composite resin.
