Can a Tooth Be Replaced If the Root Is Still Present? Doctor’s Detailed Explanation

Hello Doctor, I have a molar that was previously severely decayed, so almost the entire crown has broken away, but I was told that the tooth root remains inside the gum. I am wondering whether, in a case where the tooth root is still present, it is possible to have a new tooth placed, or whether the entire root must be extracted before restoration. I would also like to ask whether, if the root is preserved, there is any method of placing a porcelain crown over it, or whether an implant would be a better option. I hope you can advise me so that I can know which treatment method would be most suitable for me.

Hello, many people who have a broken or severely damaged tooth often wonder whether tooth replacement with the tooth root remaining is possible. In fact, in many cases, if the tooth root remains healthy, the doctor can preserve it and use it to restore a new tooth. Below is information to help you better understand tooth replacement when the tooth root remains.

Can a Tooth Be Replaced If the Root Is Still Present?

The doctor answers your question as follows: if a tooth is broken but the tooth root remains firmly anchored in the jawbone, tooth restoration can still be performed without having to remove the root completely.

In this case, the doctor will examine the condition of the tooth root, gum tissue, and jawbone to determine the appropriate restoration method. If the tooth root remains healthy, tooth replacement when the tooth root remains can help preserve the natural tooth structure and reduce treatment costs.

However, if the tooth root is infected or severely damaged, the doctor may need to remove it before proceeding with other tooth replacement methods.

Cases in Which the Tooth Root Can Be Preserved

Not every case in which a tooth root remains requires extraction. In many cases, the doctor can preserve the tooth root and restore a new tooth.

Some cases in which the tooth root can be preserved include:

  • The tooth root remains strong and healthy and is not loose
  • There is no severe inflammation or infection
  • The surrounding jawbone remains stable
  • The tooth root can undergo root canal treatment and the tooth structure can be restored

In these cases, tooth replacement with the tooth root remaining helps preserve the natural tooth structure and limits surgical intervention.

Cases in Which the Tooth Root Must Be Extracted Before Tooth Replacement

Conversely, if the tooth root is severely damaged, the doctor will recommend extraction before restoring the new tooth.

Common cases include:

  • The tooth root has severe inflammation or an abscess
  • The tooth root is cracked or fractured deeply below the gum line
  • The tooth has severe root resorption
  • The tooth root is loose and cannot be restored

In these cases, removing the tooth root and replacing the tooth will help ensure long-term oral health.

Methods of Tooth Replacement When the Tooth Root Remains

Depending on the condition of the tooth root, the doctor will select an appropriate restoration method for tooth replacement when the tooth root remains.

Placing a Porcelain Crown Over the Natural Tooth Root

If the tooth root remains strong and healthy, the doctor can prepare the tooth and place a porcelain crown over it to restore the tooth’s shape and function.

This is a fairly common method because it helps preserve the natural tooth and effectively improves aesthetics.

Using a Post and Core Followed by a Porcelain Crown

If much of the tooth crown has fractured but the tooth root remains healthy, the doctor may place a post and build up a core to create a stable foundation, followed by placement of a porcelain crown on top.

This method helps restore the tooth structure and ensures chewing function.

Tooth Root Extraction and Dental Implant Placement

If the tooth root cannot be preserved, the doctor will remove it and perform dental implant placement to replace the missing tooth root.

Dental implants are a modern restoration method that provides high durability and chewing ability that is similar to that of a natural tooth.

Procedure for Tooth Replacement When the Tooth Root Remains

The tooth replacement with the tooth root remaining procedure generally includes basic steps in dental treatment.

First, the doctor will perform an examination and take X-rays to assess the condition of the tooth root as well as the structure of the jawbone.

Then, depending on the condition of the tooth, the doctor will perform root canal treatment, build up the tooth core, or extract the tooth root if necessary.

Next, the doctor will restore the tooth using an appropriate method, such as placing a porcelain crown or performing dental implant placement.

Finally, the patient will have their bite checked and receive instructions on oral care after restoration.

Important Considerations When Replacing a Tooth in This Situation

When undergoing tooth replacement when the tooth root remains, you should choose a reputable dental clinic to ensure that the treatment process is safe and effective.

In addition, proper oral care after restoration is also very important. You should brush your teeth regularly, use dental floss, and attend periodic follow-up appointments to check the condition of your teeth.
