What is internal teeth whitening?
Internal teeth whitening, also known as internal bleaching, is a dental procedure that is specifically designed to lighten the color of a single tooth from the inside. Unlike external teeth whitening methods that focus on removing stains from the surface of the teeth, internal teeth whitening targets tooth discoloration that originates from within the tooth itself.
This procedure is usually recommended for individuals who have a tooth that has become dark or discolored after a root canal treatment. It can also be beneficial for those who have teeth with intrinsic stains that cannot be improved with traditional external whitening methods. Internal teeth whitening is a safe, effective, and minimally invasive way to restore the natural brightness and uniformity of a single tooth.
Causes of tooth discoloration
Before diving into the details of internal teeth whitening, it’s important to understand the various factors that can contribute to tooth discoloration. Tooth discoloration can be broadly categorized into two main types: extrinsic and intrinsic factors.
Extrinsic factors
Extrinsic factors refer to external substances that come into contact with the teeth and cause staining over time. Common culprits include:
- Foods and drinks: Certain foods and beverages, such as coffee, tea, red wine, and berries, can leave stains on the teeth if consumed in excess.
- Tobacco use: Smoking or chewing tobacco can lead to yellow or brownish stains on the teeth.
- Poor oral hygiene: Inadequate brushing and flossing can allow plaque and tartar to build up, leading to discoloration.
Intrinsic factors
Intrinsic factors, on the other hand, are related to changes that occur within the tooth structure itself. These factors can include:
- Aging: As we age, the enamel (outer layer of the tooth) naturally thins, revealing the yellowish dentin layer underneath.
- Trauma: Teeth that have experienced trauma, such as a fracture or blow to the tooth, may develop discoloration due to internal bleeding.
- Medications and medical conditions: Certain medications, such as tetracycline antibiotics, can cause intrinsic stains. Medical conditions like enamel hypoplasia or fluorosis can also contribute to tooth discoloration.
Understanding the specific cause of tooth discoloration is important in determining the most appropriate treatment option, such as internal teeth whitening.

Understanding internal teeth whitening
Internal teeth whitening involves the application of a bleaching agent directly to the tooth’s pulp chamber, which is the hollow space inside the tooth that houses the nerves and blood vessels. The bleaching agent works by penetrating the outer layers of the tooth and breaking down the molecules that cause the discoloration. This process helps restore the natural color of the tooth by removing or lightening the intrinsic stains.
Internal teeth whitening is typically performed by a dentist who has experience in cosmetic dentistry. The procedure requires precision and careful planning to ensure the best possible results. Not all teeth with discoloration are suitable for internal whitening, so a thorough evaluation by a dental professional is necessary to determine candidacy.
Candidates for internal teeth whitening
Internal teeth whitening is an appropriate option for individuals who have a single tooth that is significantly darker or discolored compared to the surrounding teeth. Some common scenarios where internal whitening may be suitable include:
- Discoloration after root canal treatment: Teeth that have undergone root canal therapy are often more prone to discoloration due to the removal of the dental pulp, which can affect the blood supply to the tooth.
- Intrinsic stains that do not respond to traditional whitening methods: External teeth whitening methods, such as professional dental cleanings or at-home whitening kits, may prove ineffective for certain types of intrinsic stains. Internal teeth whitening can target these stubborn stains from within the tooth.
- Dental restorations: If a dental crown or veneer is used to restore a tooth, internal whitening may be necessary to achieve a uniform color match with the natural teeth.
It’s important for candidates to have overall good oral health, with no active signs of gum disease or tooth decay. A thorough dental examination and consultation with a qualified dentist can determine if internal teeth whitening is the most suitable option.

The procedure of internal teeth whitening
Internal teeth whitening typically involves several steps that are performed under the supervision of a dental professional. These steps ensure optimal results while minimizing the risk of complications.
Preparation
Before starting the whitening procedure, the dentist will conduct a thorough examination of the tooth to assess its condition and determine the cause of the discoloration. X-rays may be taken to evaluate the roots and surrounding bone structure. Any existing dental restorations, such as fillings or crowns, will also be examined to ensure they are in good condition.
Isolation of the tooth
To protect the surrounding gum tissue from the whitening agent, a rubber dam or gel may be applied to isolate the tooth being treated. This barrier serves as a protective shield, preventing the bleaching agent from coming into contact with the gums and lips.
Application of whitening agent
The dentist will then carefully apply a whitening agent, typically hydrogen peroxide or carbamide peroxide, into the tooth’s pulp chamber. The concentration and duration of the whitening agent application will depend on the severity of the discoloration and the dentist’s professional judgment.
Light activation
In some cases, a special light may be used to activate the whitening agent and enhance its effectiveness. The light source may emit a specific wavelength of light that catalyzes the whitening process, allowing for a more rapid and efficient removal of the stains.
Repeating the process
After the initial application, the dentist will assess the progress and determine if additional whitening sessions are necessary. In some cases, the procedure may need to be repeated multiple times to achieve the desired results. The frequency of the whitening sessions and the total number of treatments required will vary depending on the individual case.
Side effects and risks
As with any dental procedure, internal teeth whitening does carry some potential risks and side effects. It’s important to be aware of these before undergoing the treatment.
Potential tooth sensitivity
One of the most common side effects of internal teeth whitening is increased tooth sensitivity. Some individuals may experience temporary sensitivity to hot or cold temperatures after the procedure. This sensitivity usually subsides on its own within a few days or weeks. Using a desensitizing toothpaste, recommended by the dentist, can help alleviate any discomfort.
Gum irritation
Since the whitening agent is in direct contact with the gums during the procedure, there is a chance of temporary gum irritation or inflammation. The dentist will take precautions to minimize contact between the agent and the gums by using a protective barrier and applying the product carefully. Any discomfort or irritation usually resolves on its own within a short period of time.
Tooth damage
Although rare, there is a small risk of tooth damage during internal teeth whitening. Overuse or misuse of the whitening agent can potentially weaken the tooth structure, leading to increased sensitivity or even tooth fracture. This is why it’s crucial to have the procedure performed by a qualified dental professional who can monitor the progress and ensure the safety of the tooth.

Results and longevity
Internal teeth whitening can provide significant improvements in the color and appearance of a discolored tooth. The exact results will vary depending on factors such as the severity of the discoloration and the individual’s response to the treatment. It’s important to have realistic expectations and understand that complete color matching with the adjacent teeth may not always be possible.
Expected outcome
In most cases, internal teeth whitening can lighten the tooth’s color by several shades, resulting in a more harmonious blend with the rest of the smile. The goal is to achieve a natural and aesthetically pleasing result that is consistent with the patient’s other teeth.
Longevity of whitening effects
The longevity of the whitening effects will depend on several factors, including the individual’s oral hygiene practices and lifestyle choices. Maintaining good oral hygiene by brushing and flossing regularly, as well as visiting the dentist for routine cleanings, can help prolong the whitening effects.
However, it’s important to note that internal teeth whitening is not permanent. Over time, the tooth may gradually darken again due to natural aging, staining foods and drinks, or other lifestyle factors. Touch-up treatments may be necessary periodically to maintain the desired level of whiteness.
Comparing internal and external teeth whitening
It’s important to understand the differences between internal and external teeth whitening methods to determine the most suitable option for individual needs.
Procedure differences
External teeth whitening methods typically involve the application of a whitening agent to the external surface of the tooth, either in a dental office or at home. These methods are generally more suitable for overall tooth whitening and stain removal, rather than targeting a specific tooth.
Internal teeth whitening, on the other hand, focuses on treating a single, discolored tooth from the inside. It is a more targeted approach that can deliver significant improvements in the color of the specific tooth. This makes it particularly beneficial for cases where external whitening methods have proven ineffective for a specific tooth.
Effectiveness comparison
Both internal and external teeth whitening methods have been proven effective in their own ways. External whitening methods can provide more comprehensive whitening results by treating all visible teeth, while internal whitening is specifically designed for treating individual tooth discoloration.
The effectiveness of internal teeth whitening largely depends on the cause and severity of the tooth discoloration. In cases where the discoloration originates from within the tooth structure, such as after a root canal treatment, internal whitening can be highly effective. However, if the discoloration is primarily due to extrinsic factors, external whitening methods may be more suitable.
It is best to consult with a dental professional to determine which method is most appropriate for achieving the desired results.

Aftercare and maintenance
To maintain the results of internal teeth whitening and promote long-lasting whitening effects, certain aftercare and maintenance steps should be followed.
Avoiding staining foods and drinks
To prevent tooth discoloration and the need for future whitening treatments, it’s important to avoid or limit consumption of staining foods and drinks. Foods and beverages such as coffee, tea, red wine, berries, and dark colas can easily stain the teeth. If consumption is unavoidable, using a straw or rinsing the mouth with water immediately afterward can help minimize staining.
Regular dental hygiene
Maintaining proper oral hygiene is key to preserving the results of internal teeth whitening. This includes brushing the teeth at least twice a day with a whitening toothpaste, flossing daily, and using mouthwash. Regular dental check-ups and professional cleanings are also essential for removing any plaque or tartar buildup and addressing any oral health issues early on.
Touch-up treatments
Over time, it is normal for the tooth to darken slightly due to natural aging and exposure to staining agents. Periodic touch-up treatments may be necessary to maintain the desired level of whiteness. These touch-up treatments can usually be performed more quickly and with less intensity compared to the initial whitening procedure.
Alternative options for tooth whitening
While internal teeth whitening is a highly effective option for treating specific tooth discoloration, there are alternative methods available for achieving a whiter smile.
External teeth whitening
External teeth whitening methods, such as professional dental cleanings, at-home whitening kits, or in-office bleaching treatments, can be suitable for overall tooth whitening and stain removal. These methods are typically more affordable and can deliver noticeable improvements in the color of multiple teeth. However, they may not be as effective for treating intrinsic stains or discolored teeth resulting from root canal therapy.
Cosmetic dental treatments
In some cases, individuals may opt for cosmetic dental treatments to achieve a whiter smile. Porcelain veneers or dental crowns can be used to cover discolored teeth, providing a long-lasting and customized solution. These treatments are versatile and can also address other dental concerns, such as tooth shape or alignment.
It is always recommended to consult with a qualified dentist to determine the most appropriate treatment option based on individual needs, preferences, and budget.
In conclusion, internal teeth whitening is a specialized dental procedure that targets tooth discoloration originating from within a single tooth. It is an effective and minimally invasive method for restoring the natural brightness and uniformity of discolored teeth. By understanding the causes of tooth discoloration and the details of the internal whitening procedure, individuals can make informed decisions about their oral health and choose the most suitable tooth whitening option. Remember to consult with a dental professional to receive personalized advice and ensure the best possible outcome for your smile.
