Home whitening kits are a popular way to turn a dull smile into a dazzling one. But these self-applied products only work for teeth with outer enamel stains — if the discoloration originates inside a tooth, you’ll need professional treatment.
Known as “intrinsic staining,” this type of discoloration most often occurs within a tooth’s pulp or dentin layers. There are a number of causes like tooth trauma or tetracycline use at an early age. A root canal treatment used to remove infection from deep within a tooth can also cause discoloration: sometimes blood pigments left after tissue removal or the filling materials themselves can stain a tooth’s interior.
Intrinsic staining can often be treated by placing a bleaching agent, usually sodium perborate, into the tooth’s pulp chamber. But before undertaking this procedure on a tooth that’s undergone a root canal treatment,Â we want to first ensure the filling is intact and still adequately sealing the tooth from infection. We also want to make sure the supporting bone is also healthy.
If all’s well, we access the pulp in the same way as the root canal treatment, and preferably through the same access hole. We then clean out the pulp chamber of any stained matter and then ensure the root canals remain filled and sealed off from the pulp chamber.
We can then place the bleaching agent into the pulp, a process that will need to be repeated every three or four days to achieve the desired level of brightness. After each session we place a cotton pellet over the opening and held in place with a temporary adhesive; we can easily remove and re-apply this covering during subsequent sessions. Once we’ve achieved the desired color change, we seal the tooth with a permanent filling and restore the access cavity with a tooth-colored composite resin material bonded to the enamel and dentin.
There are other options for an intrinsically stained tooth like veneers or crowns that outwardly cover the discoloration. Internal bleaching, however, is a more conservative approach that causes less alteration of the tooth. If successful, it can restore a stained tooth to a brighter, more attractive shade.

With its life-like color and texture, dental porcelain can restore a smile marred by decayed or damaged teeth. This durable ceramic material not only matches the varieties of individual tooth colors and hues, its translucence mimics the appearance of natural teeth. But perhaps its greatest benefit is its adaptability for use in a number of different applications, particularly veneers and crowns.
Veneers are thin layers of dental porcelain laminated together and permanently bonded to cover the visible outer side of a tooth to improve its appearance. Crowns, on the other hand, are “caps” of dental porcelain designed to completely cover a defective tooth.
Veneers and crowns share a number of similarities. Both can alter the color and shape of teeth, although crowns are used when more extensive tooth structure has been damaged. They’re also “irreversible,” meaning the tooth must be altered in such a way that it will always require a veneer or crown, though on some occasions a veneer can require no removal of tooth structure and can be reversible.
They do, however, have some differences as to the type of situation they address. Veneers are generally used where the affected teeth have a poor appearance (chipped, malformed or stained, for example) but are still structurally healthy. And although they do generally require some removal of tooth enamel to accommodate them (to minimize a “bulky” appearance), the reduction is much less than for a crown.
Crowns, on the other hand, restore teeth that have lost significant structure from disease, injury, stress-related grinding habits or the wearing effects of aging. Since they must contain enough mass to stand up to the normal biting forces a tooth must endure, a significant amount of the original tooth structure must be removed to accommodate them.
Which application we use will depend upon a thorough examination of your teeth. Once we’ve determined their condition and what you need, we can then recommend the best application for your situation. But regardless of whether we install a veneer or crown, using dental porcelain can help achieve an end result that’s truly life-changing — a new, younger-looking smile.

It’s a common problem for denture wearers: after years of a comfortable fit, your dentures now seem to be uncomfortably loose. The reason, though, may have more to do with bone loss than the dentures.
Bone is a living tissue with a life cycle — it forms, it ages, and it eventually dies and dissolves (resorbs). It’s replaced with new bone and the cycle repeats. Additionally, the forces generated when we bite or chew are transmitted from the teeth to the jaw, which helps stimulate new bone growth. When the natural teeth are missing, however, the bone no longer receives this stimulus. Resorbed bone isn’t replaced at a healthy rate, which leads over time to bone loss.
Denture construction can also contribute to bone loss. The denture palate rests for support on the bony ridges that once held the teeth. Over time the compressive forces of the dentures apply damages and reduces the volume of gum tissue and eventually does the same to the bone. Combining all these factors, the reduced gum and bone volume will eventually alter the denture fit.
There are a few alternatives for correcting loose dentures. One is to reline them with new plastic, as either a temporary fix performed during an office visit or a more permanent relining that requires sending your dentures to a dental lab. Depending on the rate of bone loss, a patient could go through several denture relinings to accommodate ongoing changes in the jaw. At some point, though, it may be necessary to create a new set of dentures.
A third alternative that’s becoming increasingly useful is to incorporate dental implants into the denture design. Implants can of course be used to replace individual teeth, but a few strategically placed implants (usually of smaller dimension) can serve as a support platform for a removable denture. This relieves some of the compression force of a traditionally worn denture and can slow bone loss.
If you’re having problems with your denture fit, call us for an appointment. We’ll help you decide on the best alternative to improving the fit and making your dentures more comfortable and secure.

While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

When they’re introducing a new movie, actors often take a moment to pay tribute to the people who helped make it happen — like, you know, their dentists. At least that’s what Charlize Theron did at the premiere of her new spy thriller, Atomic Blonde.
"I just want to take a quick moment to thank my dentists," she told a Los Angeles audience as they waited for the film to roll. "I don’t even know if they’re here, but I just want to say thank you."
Why did the starring actress/producer give a shout-out to her dental team? It seems she trained and fought so hard in the action sequences that she actually cracked two teeth!
“I had severe tooth pain, which I never had in my entire life,” Theron told an interviewer from Variety. At first, she thought it was a cavity — but later, she found out it was more serious: One tooth needed a root canal, and the other had to be extracted and replaced with a dental implant — but first, a bone grafting procedure was needed. “I had to put a donor bone in [the jaw] to heal,” she noted, “and then I had another surgery to put a metal screw in there.”
Although it might sound like the kind of treatment only an action hero would need, bone grafting is now a routine part of many dental implant procedures. The reason is that without a sufficient volume of good-quality bone, implant placement is difficult or impossible. That’s because the screw-like implant must be firmly joined with the jawbone, so it can support the replacement tooth.
Fortunately, dentists have a way to help your body build new bone: A relatively small amount of bone material can be placed in the missing tooth’s socket in a procedure called bone grafting. This may come from your own body or, more likely, it may be processed bone material from a laboratory. The donor material can be from a human, animal or synthetic source, but because of stringent processing techniques, the material is safe for human use. Once it is put in place your body takes over, using the grafted material as a scaffold on which to build new bone cells. If jawbone volume is insufficient for implants, it can often be restored to a viable point in a few months.
Better yet, when grafting material is placed in the tooth socket immediately after extraction, it can keep most of the bone loss from occurring in the first place, enabling an implant to be placed as soon as possible — even before the end of a movie’s shooting schedule.
Will Atomic Blonde prove to be an action-movie classic? Only time will tell. But one thing’s for sure: When Charlize Theron walks down the red carpet, she won’t have to worry about a gap in her smile.
