One of the most common questions that patients ask us during the consultation session is: "Does the root of my tooth have to remain to place the implant?" or "Can the implant be placed on the root of the tooth?" did?"
The short and definitive answer is: No. In order to plant an implant, the root of a natural tooth should not be present in the jaw.
Actually, a dental implant is designed to replace the root of your tooth, not sit on top of it. But why does this misconception exist? And what happens if the root of the tooth is healthy?
In this article from the site of Dr. Ehsan Birang, a specialist in gum surgery and immediate implant planting in Tehran, we fully discuss why an implant on the tooth root is not possible and what is the best solution for damaged teeth.

implant on the tooth root; A misconception or a treatment method?
Many patients imagine that the implant screw is mounted on the rest of the tooth like a veneer. This idea is caused by confusing two different treatment methods:
-
Post & Core: Restoration on natural root.
-
Dental Implant: Complete root and crown replacement.
Why can't the implant be placed on the root of the tooth?
The base of the implant (fixture) is a titanium or zirconia screw that must be welded directly to the jaw bone (osseointegration). The presence of a natural tooth root in the bone cavity prevents the placement of the fixture. Therefore, to start the implant process, the first step is complete tooth root removal.
Dr. Birang digital implant specialist in North Tehran:
"If the root of your tooth remains in the jaw, we cannot place an implant. The bone space must either be empty or the root must be removed in the same surgical session (the silent carpet method) for the implant to take its place."
So what is "tooth paste"?
If you have heard that a dentist has "put a screw on the root of a tooth", he does not mean an implant; Rather, it is a treatment called Post and Core.
-
If the root is healthy: denervation is performed, a metal rod or fiber (post) is placed inside the root and the tooth crown is reconstructed on it.
-
If the root is damaged: the root must be extracted and implant replace it.
This section is very vital for you to know if you are a candidate for an implant or not.
| attribute | Post and blind (Post) | Dental implant (Implant) |
| Location | Inside the root of a natural tooth | inside the jaw bone (root replacement) |
| need for tooth root | Yes, required | No, root must be removed |
| Lifetime | Medium (depends on root health) | very high (lifetime) |
| cost | less | More |
When should we extract the root of the tooth and implant it?
Preserving natural teeth is always our priority in modern dentistry. But sometimes insisting on keeping a weak root is just a waste of time and money. In the following cases, Dr. Ehsan Birang suggests that the root be removed and replaced with an implant:
-
Vertical fracture of the root: If the root of the tooth is broken lengthwise, it cannot be preserved.
-
Deep subgingival decay: When the decay is so deep that it is not possible to place a crown.
-
Severe tooth loosening: caused by advanced gum (periodontal) diseases.
-
Recurrent infections: Cysts and infections not treated by renervation.

Digital dentistry masterpiece: root extraction and simultaneous implantation (immediate implant)
If you are worried about "if I pull the root, how long will I be toothless?", we have your solution.
At Dr. Birang's specialized center, we use the immediate implant technique.
How is the immediate implant done?
In this method, you don't need to wait for months until the empty tooth is filled.
-
The damaged root is removed with minimal damage to the bone.
-
In the same session and immediately, the base of the implant is placed in the empty cavity of the tooth.
-
If you have good bone conditions, a temporary veneer will be installed on it to preserve the beauty of your smile.
Advantages of this method:
-
Reduce the number of surgeries (once anesthesia, once pain).
-
Prevention of jaw bone loss.
-
Keeping the natural gum shape.
Conclusion: keep the root or implant?
In response to the question "Is a tooth root necessary for an implant?" we must say: No, the tooth root is an obstacle for an implant. If your root is healthy, protect it with a crown and post. But if the root is missing or damaged, dental implant is the best and most similar replacement to your natural tooth.

FAQ
1. Does the implant hurt?
No, implant implantation is done under local anesthesia or sedation, and it is usually less painful than tooth extraction.
2. If my tooth root has been extracted years ago, can I still get an implant?
Yes, one hundred percent. In fact, the lack of root is the main condition of the implant. If it has been a long time and the bone has weakened, you may need a bone graft.
3. How much does the implant cost in 1404?
The cost varies depending on the implant brand (Swiss, Korean, etc.) and the need for side surgeries. For detailed information, we suggest you refer to the Dental Implant Price page.
