Internal Bleaching

About Internal Bleaching:

Internal Bleaching in Chatswood is a specialized treatment that whitens a tooth from the inside out. Teeth that have experienced trauma or undergone root canal therapy may become internally discoloured, appearing darker than surrounding teeth.

During the procedure, a professional bleaching agent is carefully placed inside the affected tooth to restore its natural shade. Once the whitening is complete, the tooth is sealed to prevent future staining and protect it from damage.

Our Chatswood dentists provide gentle and effective tooth whitening treatments for discoloured teeth, helping you achieve a brighter and more uniform smile.

General FAQs

What is internal tooth bleaching and how does it work?

Internal tooth bleaching is a dental procedure that whitens a single discoloured tooth from the inside out, targeting stains that originate within the tooth. It is typically used on non-vital teeth, such as those that have had a root canal or experienced trauma. Unlike regular teeth whitening, which only treats surface stains, internal bleaching addresses deeper discoloration to restore a natural and bright appearance. This procedure should be performed by a qualified dentist or endodontist.

Am I a good candidate for internal bleaching?

You may be a good candidate for internal bleaching if you have a single tooth that is discoloured from trauma or a previous root canal and the tooth is otherwise healthy. Teeth with extensive damage, decay, or active oral disease may not be suitable, so a dental assessment is necessary to determine if this treatment is appropriate for your situation.

How long does internal bleaching take to show results?

Internal bleaching results usually become noticeable within a few days, with the full whitening process completed over a few weeks. Most cases require two to four appointments, depending on the severity of the tooth’s discoloration.

Is internal tooth bleaching painful?

Internal tooth bleaching is generally not painful because it is performed on teeth that have undergone root canal treatment and no longer contain a living nerve. Most patients experience a comfortable procedure, though mild, temporary sensitivity or discomfort may occur afterward.

How should I care for my tooth after internal bleaching?

After internal bleaching, avoid staining foods and drinks for at least 48 hours, use gentle brushing with desensitizing toothpaste if needed, and maintain excellent oral hygiene. Always follow your dentist’s instructions for the best results.
