What is Internal Bleaching?
A single dark tooth in an otherwise bright smile draws the eye like nothing else, and no amount of whitening toothpaste or over the counter strips will fix it. That is because the discoloration comes from inside the tooth. Internal bleaching at Williamsburg Endodontics treats the problem at its source, lightening the tooth from within so it blends back into your smile.
Teeth darken internally for a handful of reasons. The most common is trauma: a blow to the tooth can cause bleeding inside the pulp chamber, and the blood breakdown products stain the dentin from the inside out, sometimes years after the original injury. Root canal treated teeth can also discolor over time, either from remnants of pulp tissue or from older filling materials used in past decades. External whitening products cannot reach any of this, because the stain sits beneath the enamel rather than on it.
Internal bleaching, sometimes called non vital bleaching, places a whitening agent directly inside the tooth. Because the tooth has already had root canal treatment, or receives one as the first step, there is no living nerve to protect and the pulp chamber becomes the treatment site itself. The bleaching agent works outward through the dentin, lifting the stain from precisely where it lives.
What can you expect during internal bleaching at our Brooklyn office?
Treatment at our Hope Street office begins with an evaluation to confirm the discoloration is truly internal and the existing root canal is sound, since bleaching over a failing root canal would trap infection. We then place a protective barrier over the root filling, apply the whitening agent inside the pulp chamber, and seal the tooth with a temporary filling.
Depending on the depth of the stain, the agent may be refreshed over one or more short visits until the tooth reaches the shade of its neighbors. The visits are comfortable, quick, and require no anesthesia in most cases, since the tooth has no living nerve. Once the target shade is reached, we remove the bleaching agent and place a final restoration to seal the access point.
Patients from across Williamsburg and Greenpoint come to us for internal bleaching before weddings, job changes, and photo heavy milestones, and the reaction is nearly always the same: relief that such a visible problem had such a conservative solution.
What are the benefits of Internal Bleaching?
For the right tooth, internal bleaching offers a combination of results and conservatism that no alternative can match.
It treats the stain where external whitening cannot
Whitening strips, trays, and in office external treatments brighten enamel surfaces. An internally stained tooth will stay dark through all of them, because the discoloration lies in the dentin beneath. Internal bleaching is the only whitening approach that reaches it.
It preserves your natural tooth structure entirely
The conventional cosmetic fix for a dark tooth is a veneer or crown, both of which require permanently removing healthy enamel and committing to replacement cycles for the rest of your life. Internal bleaching changes only the color. Your tooth keeps its natural shape, translucency, and structure.
It is efficient and remarkably affordable
Compared with a crown or veneer, internal bleaching is faster, far less invasive, and significantly less expensive, and if the shade ever regresses years later, the procedure can often simply be repeated.
If a single dark tooth has been bothering you, an evaluation will tell you quickly whether internal bleaching can fix it. Our Williamsburg office is located at 147 Hope Street, Suite A, a short walk from the Lorimer Street and Metropolitan Avenue stations on the L and G trains. We welcome patients from Williamsburg, Greenpoint, Bushwick, and across Brooklyn. Book your consultation online today.
