A chipped front tooth can be a very unsettling thing for a person of any age. Before the bonding era, the tooth would have to be whittled and a crown (cap) placed. Now, front teeth can be restored to the point where the repair is virtually imperceptible. The tooth is first cleaned up and any rough edges are smoothed. A long bevel is prepared on the enamel surface to increase the amount of enamel that is available for bonding. Then, an acid solution is applied to the surfaces. After rinsing, thousands of microscopic crevasses are present. Although they are very tiny, these areas allow for a liquid plastic to be flowed into these crevasses then hardened with an intense light source. This alone is adequate to retain the repair in place for a number of years.
Dr. Gangwisch Repaired This Tooth With Bonding
A composite (tooth-colored filling material) is then color matched with the remaining tooth. It is built up in multi-colored increments in order to mimic nature. Each layer is light hardened, then it’s time to contour and polish the restoration. The resulting filling looks great when it is finished. With proper care, this repair can last five to ten-plus years. Since it is not as durable as porcelain, one must be careful not to bite on hard things with it. The tooth may eventually require a crown, but repairing a chipped front tooth with a bonded filling can be a conservative, less-expensive alternative.
Once a root canal has been completed, it is extremely important that the tooth be properly restored. If not, then there would be a good chance that the tooth could be lost permanently. The reason for this is the dental pulp which houses a collection of nerves and blood vessels in the center of the tooth will bathe the inner tooth layer (the dentin) with fluid, allowing the tooth to flex under load. Once the source of the moisture is gone, the tooth becomes very brittle. I always recommend that all chewing teeth have a crown placed soon after a root canal has been completed. I have even had the unfortunate experience of needing to extract a tooth only weeks after root canal treatment due to the tooth fracturing through to the root because it had not been properly restored yet. Some front teeth, if they have adequate remaining tooth structure, can be restored with just a filling.
Crown Over Root Canal Tooth
To place a crown on a back tooth, usually a crown buildup needs to be done. A crown buildup is a core of filling material that is used to replace the tooth structure that was lost in the root canal process and due to decay. This core may need to be retained with pins or a large post that is placed in one of the canals. With a quality, well-timed final restoration covering and protecting a root canal tooth, that tooth should give decades of future service.
