Root canals are the hollow channels reaching from the central chamber to the bottom of the tooth roots. The endodontic root canal treatment is often called by the same name; others in the dental field refer to it as a root canal procedure, therapy, or surgery.
When one experiences tooth pain or has a deep cavity, the dentist may determine that a root canal procedure is necessary. First an x-ray of the tooth is taken to find out how close the damage is to the nerve inside the pulp chamber of the tooth. Often, if a cavity is found to be near the pulp, the pulp will have already become infected. In this case a root canal procedure will eliminate the pain and remove any infected tissue. If tooth infection is allowed to continue untreated, the patient may lose the tooth completely, necessitating a dental implant or bridge.
Root canal treatment starts by cleaning out damaged areas of the tooth. This is generally performed under local anesthetic, so the root canal procedure is generally no more uncomfortable than getting a filling. Once the dentist has breached the pulp chamber, further anesthetic may be injected directly into the nerve of the tooth. This effectively deadens any further pain.
The tissue is removed within the pulp chamber and any remaining nerve is cleaned from the root chambers. Once the dental pulp tissue has been cleared, the dentist widens the root canal slightly and straightens the pulp chamber to prepare it for filling. The inside of the tooth is then disinfected. Once the tooth has been properly prepared, it is filled with a rubber-like material called gutta-percha filling. The pulp chamber is packed with cotton, and a temporary filling is used to seal the opening. During a succeeding visit, the temporary filling is removed, and the pulp chamber is filled with a core buildup, and the tooth is repaired with a crown.
Root canal procedures have earned a misleading reputation for pain. During root canal procedure, the nerve and pulp tissue of the affected tooth is removed. This is done to eliminate the pain from a damaged tooth and to remove infected tissue. The empty space is filled, and the tooth is capped with a crown. A tooth that has undergone root canal therapy should be pain-free and structurally strong.
The reality is that in most cases the pain after a root canal treatment is less than the throbbing that you would experience by leaving damaged root canals untreated. There are a variety of sedation dentistry methods that can be used to make your experience more comfortable and stress-free.
SINGLE VISIT DENTAL RESTORATIONS USING CEREC
Your time is valuable and we appreciate that. That is among the many reasons we have added single visit ceramic restorations using the CEREC CAD/CAM computer to increase the options we can offer you.
This addition to our office allows us to perform many dental restorations in just one visit …that’s right you can be in and out in a single visit with a permanent, all ceramic crown, or onlay!
The CEREC uses tooth coloured ceramic materials that are bonded to your teeth. This allows us to save more of your original tooth structure while creating a natural looking, strong and functional restoration. No black lines at your gumline from oxidizing crown metals!
This ceramic material used for Cerec restorations wears more similarly to your original tooth enamel compared to silver, gold or white fillings. With the restoration being completed in a single visit there are fewer injections, less drilling, and less time needed in the chair.
A crown is a tooth-shaped “cap” that is placed over a damaged or misshaped tooth to cover restore its shape and size, strength, and improve its appearance.
A dental crown may be needed in the following situations:
- 1. To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth
- Tobacco use
- To restore an already broken tooth or a tooth that has been severely worn down or had root canal therapy
- To cover and support a tooth with a large filling when there isn’t a lot of tooth left
- To cover misshapened or severely discolored teeth
- To cover a dental implant
- Metals used in crowns include gold alloy, other alloys (for example, palladium) or a base-metal alloy (for example, nickel or chromium). Compared with other crown types, less tooth structure needs to be removed with metal crowns, and tooth wear to opposing teeth is kept to a minimum. Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. Also, metal crowns rarely chip or break. The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.
- Porcelain-fused-to-metal dental crowns can be color matched to your adjacent teeth (unlike the metallic crowns). The crown’s porcelain portion can also chip or break off. Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. However, sometimes the metal underlying the crown’s porcelain can show through as a dark line, especially at the gum line and even more so if your gums recede. These crowns can be a good choice for front or back teeth.
- All-resin dental crowns are less expensive than other crown types. However, they wear down over time and are more prone to fractures than porcelain-fused-to-metal crowns.
- All-ceramic or all-porcelain dental crowns provide the best natural color match than any other crown type and may be more suitable for people with metal allergies. However, they are not as strong as porcelain-fused-to-metal crowns and they wear down opposing teeth a little more than metal or resin crowns. All-ceramic crowns are a good choice for front teeth.
