What is a root canal?
A root canal is one of the most common dental procedures performed, well over 14 million every year. This simple treatment can save your natural teeth and prevent the need of dental implants or bridges.
At the center of your tooth is pulp. Pulp is a collection of blood vessels that helps to build the surrounding tooth. Infection of the pulp can be caused by trauma to the tooth, deep decay, cracks and chips, or repeated dental procedures.
Root Canal Signs
If you have any of these symptoms, it may be an indicator of a root canal:
- Minimal to severe pain.
- Tooth discoloration.
- Swelling and irritation in the surrounding gum tissue.
- Signs of infection visible on a radiograph.
How is a root canal performed?
If you experience any of the above symptoms, your dentist will most likely recommend root canal treatment to eliminate the diseased pulp. This injured pulp is removed and the root canal system is thoroughly cleaned and sealed. This therapy usually involves local anesthesia and may be completed in one or more visits depending on the treatment required. Success for this type of treatment occurs in about 90% of cases.
What happens after treatment?
When your root canal therapy has been completed, our doctors will decide on what type of restoration is necessary to protect your tooth. It is rare for endodontic patients to experience complications after routine endodontic treatment or microsurgery. If a problem does occur, however, we are available at all times to respond. To prevent further decay, continue to practice good dental hygiene.
Dislodged Teeth Richmond VAInjuries to the mouth can cause teeth to be pushed back into their sockets. Your endodontist or general dentist may reposition and stabilize your tooth. Root canal treatment is usually started within a few weeks of the injury and a medication, such as calcium hydroxide, will be placed inside the tooth. Eventually, a permanent root canal filling will be implanted.
Sometimes a tooth may be pushed partially out of the socket. Again, your endodontist or general dentist may reposition and stabilize your tooth. If the pulp remains healthy, then no other treatment is necessary. Yet, if the pulp becomes damaged or infected, root canal treatment will be required.
Avulsed (Knocked Out) Teeth Richmond VAIf an injury causes a tooth to be completely knocked out of your mouth, it is important that you are treated immediately! If this happens to you, keep the tooth moist. If possible, put it back into the socket. A tooth can be saved if it remains moist. You can even put the tooth in milk or a glass of water (add a pinch of salt). Your Endodontist may start root canal treatment based upon the stage of root development. The length of time the tooth was out of your mouth and the way the tooth was stored, may influence the type of treatment you receive.
Injuries in children
An injured immature tooth may need one of the following procedures to improve the chances of saving the tooth:
This procedure encourages the root to continue development as the pulp is healed. Soft tissue is covered with medication to encourage growth. The tip of the root (apex) will continue to close as the child gets older. In turn, the walls of the root canal will thicken. If the pulp heals, no additional treatment will be necessary. The more mature the root becomes, the better the chance to save the tooth.
In this case, the unhealthy pulp is removed. The doctors place medication into the root to help a hard tissue form near the root tip. This hardened tissue provides a barrier for the root canal filling. At this point, the root canal walls will not continue to develop, making the tooth susceptible to fractures so it is important to have the tooth properly restored by your dentist.
- Pain when chewing
- Temperature sensitivities
- Release of biting pressure
- It is also common for pain to come and go, making it difficult to diagnose the cause of discomfort
Chewing can cause movement of the cracked pieces of your tooth, and the pulp within the tooth becomes irritated. At the same time, when biting pressure is released, the crack can close quickly, resulting in sharp pain. Eventually, the pulp will become damaged and the tooth will consistently hurt, even when you are not chewing. It is possible that cracks can lead to infection of the pulp tissue, which can spread to the bone and gum surrounding the problematic tooth.
Types of Cracks
These are tiny cracks that only affect the outer enamel of the tooth. These cracks are more common in adults. These types of cracks are superficial and are usually of no concern. When a cusp becomes weakened, a fracture may result. The cusp may break off or be removed by a dentist. A fractured cusp rarely damages the pulp, so a root canal is not necessary. Your dentist will usually restore the tooth with a full crown.
This type of crack extends from the chewing surface of the tooth and vertically migrates towards the root. In some cases, the crack may extend below the gum line. It is possible for the crack to extend further into the root. Damage to the pulp is commonplace. In this case, root canal treatment is usually necessary. A cracked tooth that is not treated will worsen, resulting in the loss of the tooth. Therefore, early detection is essential.
A split tooth is usually the result of an untreated cracked tooth. It can be identified by a crack with distinct segments. This type of tooth can never be saved intact. Yet, the position and extent of the problem will dictate whether any portion of the tooth can be saved. Sometimes, endodontic retreatment by the doctors and restoration by your dentist can be used to save a portion of the tooth.
Vertical Root Fracture
A vertical root fracture begins at the root and extends towards the chewing surface of the tooth. Unfortunately, they show minimal symptoms and may go unnoticed. Treatment involves endodontic surgery, if a portion of the tooth can be saved, by removal of the fractured root. Otherwise the tooth will have to be extracted.
