If you’ve noticed a single tooth that looks darker than the others—even after professional teeth whitening—it could be a sign that internal staining is at play. At Atlantic Endodontics in North Charleston, SC, we specialize in advanced endodontic solutions, including internal bleaching, a powerful technique used to restore brightness from the inside out. Whether the discoloration is the result of trauma, previous dental treatments, or root canal therapy, our gentle and effective internal bleaching process can help you feel confident about your smile again.
What Is Internal Bleaching?
Unlike external whitening treatments that lighten surface stains, internal bleaching targets discoloration within the tooth. This technique is commonly recommended for non-vital (no longer living) teeth that have darkened due to injury, decay, or past dental procedures. Internal bleaching is a specialized procedure performed after root canal therapy, where a bleaching agent is placed inside the tooth to lift deep, intrinsic stains from within.
At Atlantic Endodontics, we perform this treatment with precision and care, restoring both the aesthetics and function of your smile.

Why Teeth Discolor From The Inside
There are several reasons a tooth may develop internal staining, including:
- Trauma to the tooth that causes internal bleeding
- Residual blood or tissue left behind after a root canal
- Materials used in past root canal treatments
- Decay or infection that damaged the internal structure
Because these stains develop inside the tooth, they won’t respond to regular whitening products. That’s where internal bleaching comes in—it penetrates and breaks down stains at the source.
Our Internal Bleaching Procedure
The internal bleaching process at Atlantic Endodontics is safe, minimally invasive, and highly effective. Here’s what you can expect:
- We evaluate the tooth to ensure it is healthy and has had appropriate root canal treatment
- A small opening is made in the back of the tooth to access the internal chamber
- A specialized bleaching agent is placed inside the tooth
- The opening is sealed temporarily while the agent works over several days
- After the desired shade is achieved, we remove the bleach and permanently restore the tooth
Some cases may require multiple sessions to achieve the best results, but many patients notice significant improvement after just one or two visits.
Benefits Of Internal Bleaching
Choosing internal bleaching can offer a number of cosmetic and psychological benefits:
- Restores natural tooth color and brightness
- Improves overall smile aesthetics without invasive restorations
- Preserves your natural tooth structure
- Fast, affordable alternative to veneers or crowns for single-tooth discoloration
- Boosts confidence in social and professional settings
This targeted approach is ideal for patients who want to enhance the appearance of one discolored tooth without altering the rest of their smile.
Is Internal Bleaching Right For You?
You may be a great candidate for internal bleaching if:
- You’ve had root canal treatment and now notice discoloration
- You have a single tooth that looks darker than surrounding teeth
- You’re looking for a non-invasive cosmetic solution
- The tooth is healthy and free of decay or infection
Our endodontic specialists will thoroughly evaluate your dental history, perform an exam, and determine if internal bleaching is the right treatment for you.
