Everyone has different attitudes towards stumps and crowns, and what should I do if I can't pull them out? Is there any harm in leaving it alone all the time? I'm going to talk to you about it today.
What is a stump and a stump crown?
Most of the tooth crown is defected due to caries and other reasons, which is called residual crown; The crown is basically missing, and only the root remains, which is called the stump. And we usually call this level of decay a rotten tooth.
What to do with stumps and crowns?
Try to keep it for repair.
Some people say that dentures such as dental implants are also very good now, but is it not good to just pull them out and do dental implants? Although the stump and crown look bad, it does not necessarily have to be extracted, and compared with dental implants, natural tooth roots also have certain advantages.
Advantages of retaining the stump and crown:
Good for alveolar bone health.
It is beneficial to the alveolar bone health, and the occlusal force is transmitted to the alveolar bone along the long axis of the root through the periodontal ligament and stimulates the alveolar bone.
Reduces occlusal injury.
Tooth root retention also preserves the sensory effect of the periodontal itself, which can avoid damage to the surrounding tissues caused by excessive occlusal force.
Prevents elongation of the jaw teeth.
When masticatory function is restored, displacement of adjacent teeth due to defects and the possibility of elongation of the corresponding teeth that are in contact with the bite can be prevented.
It is convenient for the protection of natural teeth.
The restored root crown can be used as an abutment tooth to repair dentition defects. Therefore, the dentist's attitude towards such stumps and stumps is to preserve them as much as possible.
Under what circumstances can the stump be retained?
There are four conditions that need to be met:
stump crown defect to the subgingival but not more than 3mm;
periodontal health; X-rays show sufficient length and thickness of the root without severe deformity;
After a complete root canal** and filling, observation for more than 3 weeks to determine that there are no symptoms, then preservation repair can be performed.
Of course, there are certain risks associated with preserving and repairing stumps and crowns, such as time-consuming, laborious and costly. Therefore, whether to retain the root of rotten teeth is not only to listen to the doctor's professional judgment, but also to combine your subjective needs.
Which stumps should be removed?
Although there are many advantages to retaining stumps and stumps, all stumps and stumps can be retained and utilized. In these cases, it is best to pull it out quickly!
Look at the degree of looseness, the root looseness is larger (loosening above the third degree), pull!
Look at the shape of the tooth root, the tooth root is short, pull it out!
Look at the relationship between the root section and the gums, and pull out the stump that is hidden deep under the gums and cannot be exposed even if it is crowned and lengthened!
Do you need a root canal for rotten tooth roots**?
Yes! If you want to preserve the residual root and crown, you need to undergo a well-developed root canal**.
Why? Because when the residual root and crown are formed, the pulp located in the innermost part of the tooth has been exposed, and the infection may have invaded the apex, and the enamel part of the dentin part involves the pulp cavity and the apical lesion appears, if the infection is not eliminated, the gum is likely to be affected by the infection, and there will be symptoms such as pus, swollen and painful gums, and painful chewing.
The root canal** is to clean away these infected materials and avoid re-infection. Of course, you don't need to go through this step if you choose to pull out the stump.
There are three common methods of root and crown restoration.
At present, the repair methods of stump and crown include: pile core crown, denture restoration, inlay restoration, etc.
For those with a large number of crown losses or even root involvement, a single tooth root can be piled for crowning. Since there is less remaining tooth tissue, a portion of the restoration is inserted into the root canal to obtain retention in order to increase retention, which is called a pile. In the early days the pile and crown were one, but now it has been upgraded, and the pile and the outer full crown are made separately and independently, called the pile core crown.
For teeth with short roots that cannot meet the reasonable crown-root ratio requirements for single restoration, joint crown restoration can be performed together with adjacent teeth, and it is necessary to grind out the good teeth next to them for bypassing, also known as crown bridge, to increase the support and retention force.
For the root is too short to do a pile nucleus crown, the doctor will consider overdenture restoration or post-extraction denture restoration after root canal**, such as removable denture, crown bridge, implant restoration, etc.
One might ask:
Is it okay for me to leave it alone?
Not recommended! Because the stump is left untreated for a long time, it is easy to expose the pulp cavity and root canal of the tooth to the bacterial environment of the oral cavity, and the bacteria can reach the root tip through the root canal, forming inflammation around the root tip, making the tooth a lesion, further affecting other healthy teeth and even causing systemic diseases.
Secondly, when the stump continues to develop and continuously irritate the mucosa, the oral mucosa may even become malignant, forming oral cancer.
So if you want to save time and money, don't wait until the caries has progressed to this stage before you think about saving it. Finally, we remind everyone that you should brush your teeth carefully, pay attention to oral hygiene, and clean your teeth regularly to prevent tooth decay.
