Treatment Plan

  • Internal bleaching of discolored root canal tooth
  • External bleaching of all teeth for even baseline color
  • Four porcelain veneers on upper front teeth
  • Color matching to harmonize with natural adjacent teeth

When Less Is More

This young patient came to us with a specific concern: a single discolored tooth from an old root canal. She wanted improvement but didn't want extensive work. Her instinct was to simply veneer the dark tooth and be done with it. Many dentists would have agreed and placed a single veneer—a quick fix that would look fine initially but create problems down the road.

We explained a different approach. A single veneer placed on a discolored tooth will never truly match the adjacent natural teeth. Over time, as her natural teeth change color from food, beverages, and normal aging, the mismatch would become increasingly obvious. What seems like the conservative choice often becomes the foundation for more extensive work later.

"Conservative dentistry isn't about doing less—it's about doing what's right."

The Proper Solution

The key was addressing the root cause: the internal discoloration from the root canal. By internally bleaching the dark tooth, we brought it back to a baseline that matched her other teeth. This is done by placing a bleaching agent inside the tooth, where the discoloration originates.

Why Internal Bleaching First?

Root canal teeth often darken from the inside due to blood breakdown products in the pulp chamber. External bleaching cannot reach this discoloration. Internal bleaching treats the problem at its source, creating an even foundation for any subsequent cosmetic work.

Next, we performed external bleaching of all her teeth. This accomplished two goals: it brightened her smile overall, and more importantly, it created an even, consistent color across all teeth. This even baseline is essential for ceramic matching.

The Conservative Approach

With all teeth now the same bright, even color, we placed just four veneers on the upper front teeth. Because the underlying tooth color was uniform, our ceramist could create veneers that perfectly match the natural teeth in both color and translucency. The result is seamless—you cannot tell where the veneers end and natural teeth begin.

  • Internal bleaching to address root canal discoloration
  • External bleaching for even color baseline
  • Four veneers that perfectly blend with adjacent teeth
  • Natural shape preserved and enhanced

The Result

The transformation demonstrates what conservative cosmetic dentistry can achieve. By taking the time to properly prepare—addressing the discoloration first, creating an even baseline, then carefully matching our ceramics—we achieved a result that looks completely natural. Four veneers that harmonize perfectly with her natural teeth, giving her the beautiful, bright smile she wanted without unnecessary treatment.

This case illustrates an important principle: conservative and limited cosmetic dentistry can have enormous impact when executed with the right approach. The goal isn't to do as little as possible—it's to do exactly what's needed, in the right order, for results that will look natural for years to come.

"Conservative and limited cosmetic dentistry can have a huge wow or impact."

Frequently Asked Questions

What causes a root canal tooth to become discolored?

When a tooth requires root canal treatment, blood breakdown products can remain in the pulp chamber and gradually discolor the tooth from within. This internal staining cannot be addressed with standard external whitening treatments.

What is internal bleaching?

Internal bleaching is a technique where a bleaching agent is placed inside the pulp chamber of a root canal-treated tooth. This targets the discoloration at its source, lightening the tooth from the inside. It's typically done over several appointments until the desired shade is achieved.

Why not just place a single veneer on the dark tooth?

While placing a single veneer seems simpler, it creates a color matching challenge. Natural teeth change shade over time, but veneers do not. A single veneer will eventually stand out as surrounding teeth naturally shift in color. Addressing the underlying discoloration first creates a stable, matched foundation.

Why bleach all teeth before placing veneers?

Creating an even baseline color across all teeth allows our ceramist to achieve a perfect match. When all teeth share the same shade, veneers can be crafted to blend seamlessly with natural teeth, making the cosmetic work invisible.

How long does conservative veneer treatment take?

This case was completed in approximately 4 weeks. The internal and external bleaching phases require time between appointments to achieve optimal results, followed by veneer fabrication and placement.
