A bright, white smile is often associated with good oral hygiene and a healthy lifestyle. Many people turn to whitening products to achieve this smile, and one of the most popular options available today are Crest Whitening Strips. But what happens if you have a root canal? Will these strips help, or could they cause harm? Let’s dive into the relationship between Crest Whitening Strips and root canals to understand how they work together  or don’t.

What Are Root Canals?

A root canal is a dental procedure that removes the infected pulp of a tooth and seals the tooth to prevent further damage. It’s typically done when a tooth becomes severely decayed or infected, and the nerve is affected. After a root canal, your tooth might be more sensitive, and it can even appear darker than the surrounding teeth. This can make people self-conscious about their smile, leading them to seek out whitening products like Crest Whitening Strips.

What Are Crest Whitening Strips?

Crest Whitening Strips are thin, flexible plastic strips coated with a whitening gel. This gel contains hydrogen peroxide, a common ingredient in many whitening products, which works to break down stains and lighten the color of your teeth. These strips are typically worn for 30 minutes a day for a set number of days, depending on the product you choose, and they’re known for being an easy and effective solution for teeth whitening.

Will Crest Whitening Strips Work on Teeth with Root Canals?

The short answer is no, crest white strips won’t whiten a tooth that has had a root canal. Here’s why: The whitening gel in the strips works by breaking down the stains on the outer surface of the teeth, specifically the enamel. A tooth that has undergone a root canal no longer has live pulp inside it, and the process often results in the tooth turning darker due to changes in the structure of the tooth. This darkening occurs because the tooth's inner structure, the dentin, can absorb stains over time. The whitening products, including Crest Whitening Strips, only target the outer enamel layer, meaning they can't change the color of the inner part of the tooth that has darkened after a root canal.

Can You Whiten Teeth After a Root Canal?

While whitening strips might not be effective on a tooth that has had a root canal, there are other options for brightening up your smile. Many dentists offer professional whitening treatments that can target the entire tooth, including those that have had root canals. For example, some dentists use internal bleaching methods for teeth that have undergone a root canal. This procedure involves placing a whitening agent inside the tooth, which can help lighten the darkened tooth from the inside out. Another option is to get a dental crown placed over the root-canal-treated tooth. Dental crowns not only restore the appearance of the tooth but also protect it from further damage. These crowns can be custom-designed to match the color of your natural teeth, ensuring that your smile stays uniform.

Conclusion

If you have had a root canal, Crest Whitening Strips won’t be effective in whitening the treated tooth. However, there are still ways to achieve a bright, consistent smile. Consult with your dentist for the best treatment options, whether it’s professional whitening or restorative procedures like crowns. No matter the solution, it’s important to remember that maintaining good oral hygiene is key to a healthy and beautiful smile.
