A cast post and core is a one-piece unit. The post section is placed into the inner part of the tooth, and the core provides a foundation for a crown.
It is precision-crafted in a dental laboratory, so the procedure may take two or more appointments. The procedure is performed after the tooth has been treated with root canal therapy and before placing the crown.
On your first visit, we numb the area completely to keep you comfortable. We may also place a rubber dam to protect your mouth while we work. Then we remove any decay and shape the tooth to accept the final crown. We remove some of the filling material that was placed into the roots of the tooth during the root canal procedure. Then a space is prepared in the inner part of the tooth for the post and core.
Next we make a specialized impression that will provide the exact dimensions of both the inner and outer portions of the tooth. Using the impression, the lab makes the post and core to precisely fit your tooth and the final crown.
In the meantime, we usually place a temporary crown to protect your tooth. On your next visit, we remove the temporary, cement in the new post and core, and then adjust it if necessary. Last, we place the crown. The benefits of a cast post and core Placing a cast post and core in a tooth prior to placing a crown—.
A cast post and core procedure is an important step in saving a tooth that has been severely damaged by fracture or decay. After a tooth has had root canal therapy, we recommend placing a crown on the tooth. Root canal therapy reduces the strength of the tooth, and a crown can cover and protect it.
Root canal therapy leaves a tooth brittle and weak. The tooth is weaker also because only the sides of the tooth are left for support when the center of the tooth is gone. These factors make it much easier for a tooth to break when you bite down on food. Biting and chewing place a tremendous amount of force on teeth, and weak, brittle teeth are especially vulnerable.
A crown can prevent these problems by covering and protecting the tooth and restoring its strength and shape. There are many kinds of crowns, including crowns made of gold, porcelain-fused-to-metal, and porcelain.
Now that you have had root canal therapy, it is important to follow these recommendations to ensure healing.
If we placed a temporary filling or crown on your tooth, avoid chewing for at least one-half hour to allow the restoration to harden. To keep your temporary restoration in place, avoid eating hard or sticky foods, especially chewing gum. If possible, chew only on the opposite side of your mouth. It is not a problem for a small portion of a temporary filling to wear away or break off, but if the entire filling wears out, or if a temporary crown comes off, call us so that it can be replaced.
If we used an anesthetic during the procedure, avoid chewing until the numbness has completely worn off. Your lips, teeth, and tongue may be numb for several hours.
If antibiotics were prescribed, continue to take them for the indicated length of time, even if all symptoms and signs of infection are gone.
To control discomfort, take pain medication before the anesthetic has worn off or as recommended. It is normal to experience some discomfort for several days after a root canal appointment, especially when chewing. To further reduce discomfort or swelling, rinse your mouth three times a day with warm salt water.
Use about one teaspoon of salt per glass of warm water. Call our office if your bite feels uneven, if you have sensitivity or discomfort that increases or continues beyond three or four days, if your temporary filling or crown comes off, or if you have any questions or concerns.
My husband and I both needed extensive dental work…and so, we actually flew to New York to see Dr. Edalat, after meeting one of his students who had raved about Dr. Edalat and his office. Both my husband and I feel and look so much better after our treatment. Automated page speed optimizations for fast site performance. Schedule an Appointment. Root canal diagnosis is the procedure of determining whether a root canal treatment, retreatment, or endodontic surgical procedure is the best solution to treat a particular dental problem.
Prior to treatment, proper diagnosis of the problem is critical. We use multiple tests and evaluations to reach a correct diagnosis.
First of all we will assess your symptoms—meaning what you can tell us about your dental problem. How long has the tooth been bothering you? When does it bother you? Can you still function with the tooth and to what extent?
History will give us many important clues, helping us make an accurate diagnosis and develop an appropriate treatment plan. We will next assess objective signs to confirm which tooth the pain is coming from and whether root canal treatment is the best option for the patient.
X-ray results, fistulous tracts, tooth discoloration, and nerve exposure are the main indicators that a root canal is necessary. Dentists may also use testing methods to determine the need for a corresponding treatment. Testing methods for determining whether a root canal is necessary include:. A dentist can tap on the problem tooth to determine whether pain appears when adequate pressure is applied.
The painful feeling can mean that a root canal is required. With the same idea, a specialist can use thermal and electric testing. Selective anesthesia is used to identify the source of the pain when a patient cannot clearly indicate the tooth that is causing it.
Additional x-rays can clearly show whether a radiolucency is present when the first film has not managed to provide any information. In cases where a dentist cannot be sure the current tooth is the problem, or he or she is suspicious that the nerve is dead, then a cavity test may be applied, where a specialist drills a divot into the tooth to check whether the nerve tissue is healthy.
Taking into account that there is no more effective method to eliminate root canal infections, endodontic surgery has doubtless benefits over tooth extraction or ignoring the problem, in general. This kind of treatment does, however, also have several unavoidable disadvantages. Root canal dangers and discomforts are actually the cost of saving your tooth. Being aware of possible negative consequences, patients should approach their qualified dentist who can professionally strengthen the treated tooth to avoid its cracking in future, and clean the canal as effectively as possible.
Choosing a specialist who can perform all operations and necessary treatments in a timely manner, and with reliable materials and a deep level of expertise, is important to ensuring a high quality of medical care.
Dentists who specialize in root canal therapy are called endodontists; however, both dentists and endodontists can perform this kind of treatment. So, who should you approach for your treatment? Since root canals are the specialization of endodontists, they have a deeper expertise, more practical knowledge, and better experience in this kind of therapy.
According to the U. This means that both types of specialists ensure the equally-high effectiveness of their endodontic treatments for short and medium-term outcomes.
Therefore, endodontists perform root canal treatments a bit better, and more reliably, from a long-term perspective. When a tooth is fully formed, it can survive without the pulp due to the surrounding tissues. In this paragraph, we will cover all the stages of root canal surgery, including:. X-rays allow an endodontist to clearly identify damage to the pulp and determine the shape of your root canal. This technique also helps the specialist identify the location of a dental infection, and damage to the surrounding bone.
At this stage, a professional applies a local anesthetic to eliminate any possible pain a patient may experience. Despite the fact that inner nerve usually is dead in these situations, a dentist may still apply anesthesia to eliminate any possible pain. A dental dam is a rubber sheet to ensure a dry area surrounds the problem tooth. This dam prevents saliva accessing the treated area.
An endodontist creates an opening in your tooth to access the infected pulp. Since an anesthesia is applied, this process will not cause any pain. Once the hole is made accurately, the specialist removes the bacteria-infected pulp with thorough root canal scrubbing. In cases where your tooth contains the inner infection, a dentist medicates the internal tooth area to remove bacteria. Then, your tooth can be filled with a temporary material until you return on your next visit.
