Root canal treatments are the go-to procedures dentists use to treat a tooth with advanced internal decay that has resulted in the pulp (nerve) dying. And for good reason: root canals are responsible for saving millions of teeth that would otherwise be lost.
In the basic root canal procedure, dentists make access into a tooth's interior with a small hole drilled into the crown. They then remove all diseased tissue within the pulp chamber and root canals. These now empty spaces are then filled, and the tooth is sealed and crowned to prevent further infection.
This is usually a straightforward affair, although it can be complicated by an intricate root canal network. In those cases, the skills and microscopic equipment of an endodontist, a specialist in root canals, may be needed to successfully perform the procedure.
But there are also occasional cases where it may be inadvisable to use a conventional root canal procedure to treat an endodontic infection. For example, it may be difficult to retreat a root canal on a restored tooth with a crown and supporting post in place. To do conventional root canal therapy, it would be necessary to take the restoration apart for clear access, which could further weaken or damage the remaining tooth's structure.
In this and similar situations, a dentist might use a different type of procedure called an apicoectomy. Rather than access the source of infection through the tooth's crown, an endodontist approaches the infection through the gums. This is a minor surgical procedure that can be performed with local anesthesia.
Making an incision through the gums at the level of the affected root, the endodontist can then remove any infected tissue around the root, along with a small portion of the root tip. They then place a small filling and, if necessary, grafting material to encourage bone growth around the area. The gums are then sutured in place and the area allowed to heal.
An apicoectomy is another way to attempt saving a tooth that's well on its way to demise. Without it or an attempt at a conventional root canal treatment, you might lose your tooth.

Chipped a tooth? Don't beat yourself up—this type of dental injury is quite common. In fact, you probably have a favorite celebrity who has chipped one or more of their teeth. The list is fairly long.
Some chipped a tooth away from the limelight, such as Tom Cruise (a hockey puck to the face as a teen), Jim Carrey (roughhousing on the playground) and Paul McCartney (a sudden stop with a moped). Others, though, chipped a tooth while “on the job.” Taylor Swift, Hillary Duff and Jennifer Lopez have all chipped a tooth on stage with a microphone. And chipped teeth seem to be an occupational hazard among professional athletes like former NFL star, Jerry Rice.
Since smiles are an indispensable asset to high-profile celebrities, you can be sure these stars have had those chipped teeth restored. The good news is the same procedures they've undergone are readily available for anyone. The two most common restorations for chipped teeth are dental bonding and veneers.
The least invasive way to fix a chipped tooth is bonding with a material known as composite resin. With this technique, resin is first mixed to match the tooth color and then applied to the chipped area or applied in layers of color to get just the right look. After a bit of shaping, curing and adjustment, we're done—you can walk out with a restored tooth in one visit.
Bonding works well with slight to moderate chips, but it could be less durable when there is more extensive damage. For that, you may want to consider porcelain veneers. Veneers are thin wafers of dental porcelain that are bonded to the front of teeth to mask blemishes like stains, slight gaps or, yes, chips. Veneers can be so lifelike that you won't be able to tell the veneered tooth from your other teeth. They are fashioned to match the color and shape of an individual's teeth. Because of the time and design detail involved, veneers are more expensive than bonding, yet still within an affordable range for many.
Teeth require some alteration before applying traditional veneers because otherwise the teeth can appear bulky when the veneer is bonded to the existing tooth. To compensate, we remove a little of the tooth enamel. Because this loss is permanent, you'll need to wear veneers or have some other form of restoration for the tooth from then on. For many people, though, that's a small price to pay for a smile without chips.
Your first step to repairing a chipped tooth is to come in for an examination. From there, we'll recommend the best option for your situation. And regardless of which, bonding or veneers, we can change your smile for the better.

Dental visit anxiety is a serious problem: Half of all Americans admit to some level of dental fear, while 15% avoid dental care altogether due to acute anxiety. The harm this can cause to dental health is incalculable.
But dentists have a number of sedation techniques that can relax anxious patients and allow them to receive the care they need. Although often used together, sedation is slightly different from anesthesia, which aims to deaden pain sensation. The aim of sedation is to calm the emotions and state of mind.
Sedation isn't a new approach: Physicians have used substances like root herbs or alcohol to relieve anxiety since ancient times. Modern dentistry also has a long history with sedation, dating from the early 1800s with the first use of nitrous oxide gas.
Modern dental sedation has expanded into an array of drugs and techniques to match varying levels of anxiety intensity. At the milder end of the scale are oral sedatives, taken an hour or so before a dental appointment to produce a calmer state. This may be enough for some patients, or it can be used in conjunction with nitrous oxide.
For those with more intense anxiety, dentists can turn to intravenous (IV) sedation. In this case, the sedative is delivered directly into the bloodstream through a small needle or catheter inserted in a vein. This causes a quicker and deeper reaction than oral sedatives.
Although similar to general anesthesia, IV sedation does differ in significant ways. Rather than unconsciousness, IV sedation places a patient in a “semi-awake” state that may still allow them respond to verbal commands. And although the patient's vital signs (heart rate, breathing, blood pressure, etc.) must be monitored, the patient doesn't need breathing assistance as with anesthesia.
There's one other benefit: The drugs used often have an amnesic effect, meaning the patient won't remember the treatment experience after recovery. This can be helpful in creating more pleasant memories of their dental experience, which could have its own sedative effect in the future.
Whether oral, gas or IV, sedatives are a safe and effective way to calm dental fears during treatment. That could help someone with anxiety maintain their oral health.
