Internal bleaching, also called non-vital tooth whitening, is a specialized dental procedure designed to whiten a tooth from the inside. This treatment is typically used for teeth that have undergone root canal therapy and have become discolored. Trauma, certain medications, and other factors affecting the tooth's internal structure can all cause that change in color. Our expert dentist places a whitening agent inside the tooth rather than treating the outer surface. The approach is effective for discoloration that external whitening simply cannot reach.
Internal bleaching targets one individual discolored tooth rather than the whole smile, which makes it precise where other options are not where the alternatives simply are not.
The treatment resolves discoloration that simply does not respond to external whitening, particularly after trauma or root canal therapy at some point earlier in your life.
This approach preserves your natural tooth structure compared with other cosmetic options such as a crown or a porcelain veneer, which would remove far more enamel.
The procedure is minimally invasive and produces long-lasting results with proper care, which improves both confidence and smile aesthetics for the years that follow treatment.
The internal bleaching process at Smile Tustin by Dr. Ezzy typically involves the following steps.
Request an AppointmentOur expert dentist assesses the discolored tooth and confirms whether it is suitable for internal bleaching before any treatment gets underway.
A small opening is made in the back of the tooth to access the pulp chamber without affecting the front surface of the tooth people actually see.
Any remaining debris or old filling material is carefully removed from inside the pulp chamber before the bleaching agent goes in.
A whitening agent is placed inside the tooth, and a temporary filling seals it in to do its work over time inside the chamber between visits.
You may need several follow-up visits to reach the shade you want, and then the tooth is permanently sealed with a permanent restoration on top.
Darkened Tooth — One tooth is noticeably darker than the teeth on either side of it, which draws the eye when you smile in photographs and in everyday conversation.
Root Canal — That tooth has undergone root canal therapy and discolored afterward from changes to its internal structure in the months following the procedure.
Dental Trauma — Trauma or an injury to the tooth caused the discoloration rather than surface staining from food and drink or from the drinks you have daily.
Whitening Failed — External whitening treatments have already been tried on the tooth and produced no meaningful improvement on it without any noticeable change.

Real Patients, Real Stories
Dr Ezzy and her staff are knowledgeable, cheerful & attentive ! It’s a pleasure to go to the dentist when it’s Dr. Ezzy’s office!
Visited yesterday to treat my wife allergic reaction in mouth after 1 month of suffering and not treated by other medical providers. Dr.Ezzy properly diagnosed and prescribed medications working well so for.
Dr. Ezzy and the entire staff were incredibly kind, professional, and welcoming. From the moment I walked in, I felt comfortable and well taken care of. The staff was friendly and attentive, making sure all my questions were answered and that I felt at ease throughout the visit. Dr. Ezzy took the time to listen carefully and explain everything clearly, which I really appreciated. The level of care and attention to detail truly stood out. The office was clean, organized, and ran smoothly, making the whole experience even better. I’m very grateful for the excellent service and would highly recommend Dr. Ezzy and the team to anyone looking for quality care.
All systems were go, two implants were done. Same day and following day NO PAIN. Alittle discomfort but minimal at best.
Great experience! Office staff is very friendly and professional! Dr Ezzy is efficient and very concerned about comfort and quality of work!
Great staff and great customer service.
I can’t say enough good things about my experience with Dr. Ezzy. From scheduling the appointment to the actual visit, everything was smooth and stress-free. The team is friendly, organized, and genuinely cares about patients. Dr. Ezzy is not only highly skilled but also very kind and reassuring, which made a big difference for me. They took the time to listen to my concerns and made sure I felt comfortable every step of the way. The treatment was quick, painless, and done with great attention to detail. It’s rare to find a dental office that combines professionalism with such a warm and welcoming atmosphere. I’m really grateful to have found Dr. Ezzy and would confidently recommend them to anyone looking for top-quality dental care.
I had an excellent experience with Dr. Ezzy and the entire dental team. From the moment I walked in, the staff was welcoming, professional, and made me feel completely at ease. Dr. Ezzy is incredibly knowledgeable, patient, and takes the time to explain everything clearly before starting any procedure. The office is clean, modern, and well-organized, which really adds to the overall comfort. What stood out the most was the gentle care and attention to detail — I never felt rushed, and my comfort was always a priority. If you’re looking for a dentist who truly cares about their patients and delivers high-quality work, I highly recommend Dr. Ezzy. I’m very happy with my results and will definitely continue coming here.
Dr. Ezzy is a wonderful Dentist. All her staff are so nice, they compliment each other. I will definitely refer others to: Smile Tustin by Dr. Ezzy! 😉
Dr Ezzy and staff were all absolutely amazing. My cleaning was the best I have ever had. She was so gentle and made me feel at ease even though I hadn’t been for a cleaning in a while. Dr Ezzy was compassionate, caring and very thorough. She spent time explaining things and setting a plan moving forward. I highly recommend!
They are extremely tech-advanced and properly staffed. I really wish I had found them sooner. In life, you have to switch to a dentist that can provide you with proper care including having staff properly respond. Shout out to Debbie, she sealed the deal for me not because of sales skills but because of patient education and also having a seven year old CEREC crown herself. Even basic things like X-rays and numbing are done so much better here than at any other office I’ve been to. I already got a same-day CEREC crown here, and they also offer financing options. I do have several cavities and may need more crowns in the future (based on x rays from my previous dentist)—not because they are pushing treatment, but because I’ve had long-standing dental issues from large childhood fillings and nerve involvement. I’ll need to get an x ray here when I’m back and see what options they can provide to me. Maybe there are other ways. I finally found a place I trust with my long-term dental health. It’s been depressing finding one problem after another, but I feel genuinely safe starting treatment here. The staffing is especially important, because for urgent care, education, and follow-up, this is the first office that has truly met those needs.
Very professional and fantastic service from front desk to the dentist and hygienist

Changes to the internal structure of a tooth after root canal therapy commonly cause discoloration. Trauma and certain medications can produce the same effect.
You may need multiple appointments to reach the shade you want. Once the desired color is achieved, the tooth is permanently sealed.
External whitening treats surface stains and generally will not correct discoloration coming from inside the tooth. Internal bleaching is designed for exactly that situation.
The cost depends on how many appointments are needed to reach your target shade. Our team reviews the full fee with you before treatment begins.
Coverage varies by plan and often depends on whether the treatment is considered cosmetic. Our front office will verify your benefits beforehand.
One discolored tooth should not keep you from smiling in photographs. Contact Smile Tustin by Dr. Ezzy today to schedule internal bleaching in Tustin, CA, and restore your smile's natural brilliance.
