Case Study:
Radiance restored to Ms. N’s trauma-darkened tooth
What was the issue with Ms. N’s tooth?
Ms. N had long been dissatisfied with her smile, especially the trauma-induced darkness of her upper left canine. Beginning with an accident several years ago, the tooth’s dark appearance became increasingly prominent which created an unbalanced smile and significantly affected her self-confidence.
The visual effect of this combined with preexisting unevenness in her lateral incisors contributed to an overall lack of aesthetic harmony in her smile.

How her treatment began

When Ms. N came for her cosmetic consultation and treatment planning session with Dr. Su Lin and her team, she expressed her desire for a brighter, more uniform smile. Of particular importance, she preferred a non-invasive, long-lasting solution.
Through our meticulous smile design process, we determined that resin would be the ideal restorative material for this case due to its versatility and conservative nature.

Ms. N’s personalised treatment
- To address the darkened tooth, root canal treatment was performed to resolve any underlying infection.
- Internal bleaching was then undertaken to lighten the tooth from within. A bleaching agent was placed inside the tooth, allowing it to gradually regain a natural, lighter shade while preserving its structural integrity.


- Resin bonding was employed to address the uneven lateral incisors. This minimally invasive technique involved applying tooth-coloured resin to the surfaces of the teeth and carefully sculpting it to enhance their shape and size for a more symmetrical appearance.



Satisfying outcome
Ms. N was thrilled with the results of her treatment. The aesthetic improvements significantly boosted her self-confidence, enabling her to smile freely without concern about her appearance. The combination of root canal treatment, internal bleaching, and resin bonding provided a conservative yet highly effective solution to her concerns.

Beautiful confidence regained, evidence of trauma erased
Creating a bright and harmonious smile has helped Ms. N to move on from the accident which darkened her tooth. This case highlights how modern cosmetic dental procedures, such as internal bleaching and resin bonding, can dramatically transform a patient’s smile and self-esteem. Pental trauma and its ongoing visual effects need not have the final word on a person’s present appearance. Modern restorative and aesthetic dentistry techniques offer effective, minimally invasive solutions to bring beauty and greater functionality to smiles darkened by trauma.
