A root canal treatment is a highly effective way to save a deeply decayed tooth. Sometimes, though, complications make it difficult or even impossible to perform the traditional procedure. In those cases, we may need to use a different option.
Tooth decay becomes an imminent threat to a tooth's survival if it works its way into the pulp, the innermost layer of a tooth. It's only a short advancement from there into the roots by way of the root canals.
In a typical root canal treatment, we access the pulp by drilling a small hole in the biting surface of a back tooth or the back side of a front tooth. We remove all the tissue within the pulp and fill it and the root canals with a special filling to prevent re-infection. After sealing the access hole, we cap the tooth with a crown to further protect it.
Although root canal treatments have a high success rate, re-infection can still occur. Often, a second root canal will save the tooth from the new infection.
In some cases, though, using the traditional procedure might do more harm than good. It's possible we may find extra canals previously undetected branching out from the primary canal at the root end. Canals can calcify and narrow, making them extremely difficult to fill. Subsequent dental work may also prove troublesome: we would have to take the restoration apart, which could further weaken the tooth.
The alternative is a procedure known as an apicoectomy. Instead of accessing the pulp through the crown, we access the root end through the gum tissue. We then focus on removing infected tissue at the tooth's root end, along with a tiny amount of the root tip. We then place a small filling at the end of the root canal (essentially plugging it up) to prevent further infection. We may also perform grafting to encourage bone growth in any voids left by the procedure.
Endodontists, specialists in root canals, have the advanced training and specialized equipment to perform an apicoectomy. With their expertise, they may be able to save your tooth with this specialized procedure when a root canal treatment won't work.

Some people are lucky — they never seem to have a mishap, dental or otherwise. But for the rest of us, accidents just happen sometimes. Take actor Jamie Foxx, for example. A few years ago, he actually had a dentist intentionally chip one of his teeth so he could portray a homeless man more realistically. But recently, he got a chipped tooth in the more conventional way… well, conventional in Hollywood, anyway. It happened while he was shooting the movie Sleepless with co-star Michelle Monaghan.
“Yeah, we were doing a scene and somehow the action cue got thrown off or I wasn't looking,” he told an interviewer. “But boom! She comes down the pike. And I could tell because all this right here [my teeth] are fake. So as soon as that hit, I could taste the little chalkiness, but we kept rolling.” Ouch! So what's the best way to repair a chipped tooth? The answer it: it all depends…
For natural teeth that have only a small chip or minor crack, cosmetic bonding is a quick and relatively easy solution. In this procedure, a tooth-colored composite resin, made of a plastic matrix with inorganic glass fillers, is applied directly to the tooth's surface and then hardened or “cured” by a special light. Bonding offers a good color match, but isn't recommended if a large portion of the tooth structure is missing. It's also less permanent than other types of restoration, but may last up to 10 years.
When more of the tooth is missing, a crown or dental veneer may be a better answer. Veneers are super strong, wafer-thin coverings that are placed over the entire front surface of the tooth. They are made in a lab from a model of your teeth, and applied in a separate procedure that may involve removal of some natural tooth material. They can cover moderate chips or cracks, and even correct problems with tooth color or spacing.
A crown is the next step up: It's a replacement for the entire visible portion of the tooth, and may be needed when there's extensive damage. Like veneers, crowns (or caps) are made from models of your bite, and require more than one office visit to place; sometimes a root canal may also be needed to save the natural tooth. However, crowns are strong, natural looking, and can last many years.
But what about teeth like Jamie's, which have already been restored? That's a little more complicated than repairing a natural tooth. If the chip is small, it may be possible to smooth it off with standard dental tools. Sometimes, bonding material can be applied, but it may not bond as well with a restoration as it will with a natural tooth; plus, the repaired restoration may not last as long as it should. That's why, in many cases, we will advise that the entire restoration be replaced — it's often the most predictable and long-lasting solution.
Oh, and one more piece of advice: Get a custom-made mouthguard — and use it! This relatively inexpensive device, made in our office from a model of your own teeth, can save you from a serious mishap… whether you're doing Hollywood action scenes, playing sports or just riding a bike. It's the best way to protect your smile from whatever's coming at it!
