How Does Internal Tooth Bleaching Work?

December 1, 2020

There are many reasons why teeth get disclosed. Smoking cigarettes is perhaps the top and the most common, as well as taking food and beverages like coffee and red wine, which are a staining effect on the tooth enamel.

External factors, did you know that teeth can get stained from the inside? This is a common phenomenon that occurs due to a structural defect within the tooth itself. It can also occur on a dying tooth or penetration of blood or other body fluids into the tooth during an invasive procedure like root canal treatment.

Regardless of these causes, there are many opportunities to restore the tooth to its normal state and match adjacent teeth’ color. This can be achieved through bleaching the tooth from inside via a process called internal bleaching.

What is Internal Bleaching?

Internal bleaching differs significantly from tooth whitening from outside the tooth. As the name suggests, bleaching is done inside the tooth.

The procedure is generally easy and inexpensive, but many people are not aware of it and go for years with stains in their smiling zones. Studies have shown that internal tooth bleaching at Rosemarie Quimson-Cruz, DMD is a safe procedure that has excellent and long-lasting results.

Internal Bleaching Procedure

Teeth whitening in Los Angeles, CA, uses different procedures for internal bleaching. This depends on whether the tooth in question requires bleaching before a root canal treatment or if it needs a future root canal treatment.

If you require a root canal treatment, a normal tooth surgery will be conducted on the ailing tooth. This involves excavating its pulpal chamber that holds the decayed and dying tissues, then preparing it for a filling or dental crown. Therefore, in such a case, the dentist near you deposits a bleaching formula into the tooth before applying the temporary filling or crown.

This alters the color of the damaged tooth from inside-out. The bleaching agent is let to remain inside the treated toot for up to 14 days to produce maximum results. You will return to the dentist afterward for an exam on the progress.

A tooth whitening process is dramatically different when the discoloration is dues to a previous root canal treatment. In this case, the procedure involves drilling a small hole through the tooth enamel to access the pulpal tissues. Your dentist then inserts a cotton pellet drenched in the bleaching agent.

The pellet then remains within the treated tooth for a while before the next dental exam. Your dentist can send you home with bleaching trays to speed up the whitening process and achieve results faster.

What are the Side Effects of Internal Bleaching?

  • Cervical Root Resorption

Cervical root resorption occurs due to an effect of the Hydrogen Peroxide used as a bleaching agent.

The concept behind cervical root resorption is like this. When inserted, the bleaching agent escapes through dental tubules and might reach the periodontal tissue causing internal inflammation. Care must be taken when using thermo-catalytic methods on defective dentine areas to prevent cervical perforation.

  • Crown Fracture

Crown fracture is likely to occur due to excessive removal of the intracoronal dentin. Also, hydrogen peroxide is known to decrease internal dentin’s hardness, which affects the strength of ceramic brackets and crowns and can lead to a fracture when using your teeth.

  • Tooth Sensitivity

Tooth sensitivity is the most common side effect and occurs due to heat application on hydrogen peroxide. It’s common to have tooth sensitivity up to four days after treatment, which should cease at the finish of the treatment.

Does it Give Damage to the Enamel or Not?

There are multiple side effects to internal bleaching, and damage to the enamel is among them. This especially occurs if you overuse the bleaching agents on your teeth.

With so many over-the-counter bleaching agents, people are tempted to buy and use them instead of getting an in-office treatment. Get a tooth whitening treatment near you from a recognized dentist to avoid overdosing or using high concentrates, which can permanently damage your tooth enamel.

How Much does Internal Bleaching Cost?

On average, you will pay $260 – $320 per arch for internal bleaching treatment. This includes all costs for examinations, impressions, x-rays, trays, radiographs, and other necessary materials.
