Brighten Your Smile with Internal Bleaching: Preston Dentist Explains Who Needs It

A dazzling smile can boost your confidence and make a lasting impression. However, various factors can cause teeth discolouration over time, leaving you feeling self-conscious about your smile. If you're looking to regain that bright, white smile, internal bleaching might be the solution you need. In this blog post, we'll delve into what internal bleaching is and who might benefit from this dental procedure, with a focus on the services offered by your Preston dentist at Bright Smile Dental Clinic.

Understanding Internal Bleaching

Internal bleaching, also known as tooth whitening, is a cosmetic dental procedure designed to lighten the colour of a single discoloured tooth or a group of teeth. Unlike traditional teeth whitening methods that address surface stains, internal bleaching targets intrinsic stains that originate from within the tooth.

The procedure involves the following steps:


First, a thorough examination is conducted by your dentist in Preston to determine the cause and extent of tooth discolouration. This assessment helps in deciding whether internal bleaching is the right choice for the patient.


The dentist isolates the affected tooth or teeth from the rest of the mouth to prevent the bleaching agent from coming into contact with healthy teeth and gum.

Application of Bleaching Agent

A special bleaching agent, often hydrogen peroxide, is placed inside the discolored tooth. This agent works to break down and remove the internal stains.


The progress of the bleaching process is closely monitored by the dentist to ensure that the desired shade is achieved without compromising the tooth's structural integrity.


Once the tooth reaches the desired shade, the bleaching agent is removed, and the tooth is sealed with a permanent filling or dental bonding material to prevent future staining.

Who Needs Internal Bleaching?

Internal bleaching is typically recommended for individuals who have a single discoloured tooth or a small group of discoloured teeth due to various factors, including:

  • Trauma: Teeth can become discoloured after an injury or trauma that disrupts the tooth's blood supply. This can lead to a grayish or darkened appearance.
  • Root Canal Treatment: Teeth that have undergone root canal therapy may lose their vitality and develop internal stains over time, requiring internal bleaching to restore their appearance.
  • Tetracycline Stains: Long-term use of tetracycline antibiotics, especially during tooth development, can cause deep intrinsic staining. Internal bleaching can be a suitable solution for such cases.
  • Aging: As we age, our teeth naturally undergo colour changes and may become discolored. Internal bleaching can help reverse the effects of aging on tooth color.
  • Genetics: Some individuals may have genetic factors that lead to internal tooth discoloration, making them suitable candidates for this procedure.
  • It's important to note that not all teeth discolourations can be treated with internal bleaching. Patients should consult with a dentist in Preston to determine the best course of action based on their specific case.

Choosing a Preston Dentist for Internal Bleaching

When considering internal bleaching, it's crucial to choose a qualified and experienced dentist in Preston to ensure the best results. Here are some tips for finding the right dentist:

  • Research and Reviews: Look for dentists in Preston who specialise in cosmetic dentistry and have positive patient reviews regarding their internal bleaching procedures.
  • Consultation: Schedule a consultation to discuss your concerns and expectations with the dentist. This will allow you to gauge their expertise and the treatment plan they propose.
  • Accreditation: Ensure that the dentist is experienced as your Preston dentist at Bright Smile Dental Clinic.
  • Cost and Payment Options: Discuss the cost of internal bleaching and inquire about available payment options and financing plans with your Preston dentist.


Internal bleaching is a fantastic option for individuals looking to restore the natural brightness of discoloured teeth. Whether it's due to trauma, aging, or other factors, this procedure, performed by a skilled dentist in Preston, can help you regain your confidence and enjoy a radiant smile once again. If you're considering internal bleaching, don't hesitate to consult with a Preston dentist to determine the best approach to enhance your smile and overall oral health.
