Whitening strips have become a popular method for achieving a brighter smile. They are affordable, easy to use, and can be purchased over the counter or online without a prescription. However, many people who have dental restorations such as fillings wonder if whitening strips will work on their restorations.
In this article, we will discuss whether whitening strips work on fillings, the types of fillings that respond well to whitening, and any potential risks associated with using whitening strips on fillings.
How do whitening strips work?
Before we dive into whether whitening strips work on fillings, it’s important to understand how they work. Whitening strips contain hydrogen peroxide or carbamide peroxide, which penetrates the enamel of your teeth to break down stains and discoloration. This process helps to remove surface stains and whiten teeth.
Do whitening strips work on fillings?
The short answer is no, whitening strips do not work on fillings. The reason for this is that fillings are made from materials that do not react to the whitening agents found in whitening strips. Fillings are typically made from porcelain, composite resin, or amalgam, which are all materials that do not change color when exposed to hydrogen peroxide or carbamide peroxide.
Types of fillings that respond well to whitening
Although most types of fillings do not respond well to whitening, there are some exceptions. Teeth that have been filled with certain types of composite resins can sometimes be lightened with whitening treatments. However, it’s important to note that these fillings may not lighten as much as natural teeth, and the results may be uneven.
Potential risks associated with using whitening strips on fillings
While whitening strips are generally safe to use, there are some potential risks associated with using them on fillings. One risk is that the whitening agent can seep into any cracks or gaps between the filling and the tooth, causing sensitivity or damage to the filling. Additionally, if the filling is old or damaged, the whitening agent could weaken it further, leading to the need for a replacement.
Conclusion
In conclusion, whitening strips do not work on fillings made from materials such as porcelain, composite resin, or amalgam. While teeth filled with certain types of composite resins may lighten slightly with whitening treatments, the results may be uneven. It’s important to note that there are potential risks associated with using whitening strips on fillings, including sensitivity or damage to the filling. If you are considering using whitening strips and have dental restorations, it’s best to consult with your dentist first to determine the best course of action.
