Composite or "white" fillings are tooth colored polymer based resins whose physical properties are more like tooth structure as compared to Amalgam or "silver" fillings. When composites are bonded in to tooth, they create a chemical bond with the collagen matrix of the dentinal tubules of the tooth. Therefore, a well bonded composited filling behaves as one with the tooth when loaded under forces of mastication. However, the one drawback of composite fillings is that they are very technique sensitive meaning they need to be done in a specific way for them to be successful. Firstly, they require a very controlled environment with absolutely no moisture contamination. This is the reason we attempt almost all of our composite restorations under rubber dam isolation. Secondly, composites require a very precise method of placement which ensures good seal and longevity. Following the placement of a composite restoration into the tooth, it is critical to finish and polish the surface, again to ensure proper seal and longevity. At our clinic, we have invested in all the necessary armamentarium along with a strict protocol to ensure the highest quality of composite resin restorations to our patients.
These are all ceramic fillings custom made by a laboratory technician to fit a particular tooth. If they are well made, properly bonded into the tooth, and finished and polished with precision, they can last you a life time. The biggest plus point of this restoration is that it is very conservative towards tooth structure. Since these restorations are fabricated in a laboratory to custom fit your tooth, they can only be completed in two visits. In the first visit, the dentist prepares the tooth by removing all decay, takes an impression to send to the lab, and fabricates a temporary inlay/onlay to restore function back to the tooth. In the second visit, we try the lab fabricated porcelain inlay/onlay in your tooth, bond it in place and finish and polish it.
Crowns are like a cap for your tooth. They cover the entire tooth- from the eating surface down to the gum-line. A crown is usually placed on a tooth that has lost most of its standing tooth structure, and has a very large filling supported by very thin tooth walls, which are at high risk of fracturing under eating forces. Crowns may be made of a metal core with porcelain fused over top (to give it a tooth like appearance) or they may be entirely metal free ceramic restorations. Ceramic crowns are usually placed on the front teeth as they give ideal esthetic results.
Crowns also require 2 dental visits as they are also fabricated in a laboratory to custom fit your tooth.
RCT is the treatment of canals (tunnels) running through the centre of each root of a tooth. In a healthy tooth these canals are filled with nerves and blood vessels, which keep our tooth alive. If a cavity eats away at the tooth and reaches these canals, then the bacteria causing the cavity also contaminates the canals. Once this happens, the tooth starts to get sensitive to hot and cold, with the sensitivity lingering on longer than the stimulus that caused it. the tooth may also ache spontaneously, with the pain getting worse when you lie down at night.
Once the canals have been contaminated, they have to be cleaned out and disinfected completely through a meticulous cleaning process using pipe cleaner like files, which gradually progress in size and taper. Following the cleaning process, the canals are dried out and then filled with a plastic like inert material called Gutta Perka. This process of cleaning and filling the canals inside the roots of a tooth is known as root canal treatment.
