JamieFoxxChipsaTooth-ThisTimebyAccident

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!

AnImplantRestorationCouldPreventBoneLoss

Losing teeth continues to be an all too common experience for people, especially those in their senior years. Fortunately, there are several ways to replace them, ranging from partial or full dentures to implants.

Some, though, postpone or simply choose not to replace a lost tooth, often because of the cost. But putting off a dental restoration could have a long-term impact on your health, and not in a good way. Continuing bone deterioration is one of the top consequences of delayed restoration.

Like other bones in the body, the jawbone is living tissue with cells that form, grow and eventually wear out. At the end of their life, these older cells give way to new cells. Eating and chewing play an important role in maintaining this growth cycle: the forces we generate as we chew travel up through the tooth roots to stimulate bone growth in the jaw.

When a tooth goes missing, though, the stimulus ends. Over time the bone cell replacement rate can fall off and the bone slowly loses volume. To make matters worse, bone loss can continue beyond the immediate bone underlying the tooth and affect the rest of the jawbone. The jaw can shrink in height and width, and in time become weaker overall and more susceptible to fracture.

But dental implant restorations in particular could help stop or even reverse bone deterioration at the site of the missing teeth. The titanium post implanted in the jaw attracts bone cells, which grow and adhere to its surface. Over time the bone fills in and becomes stronger.

You don't want to wait too long, though, because implants depend on a minimum amount of bone present for secure placement. You should therefore undergo an implant restoration as soon as it's practical after tooth loss. Otherwise, although we may be able to restore some of the lost bone with bone grafting, you may need to consider another restorative option.

When it comes to replacing missing teeth, time isn't on your side. But the right kind of dental restoration undertaken promptly can make for a brighter, healthier future.

Tags: Root Canal  

Dealing with dental issues is certainly no fun and yet it happens more often than we would like. Of course, our Marietta, GA, dentist Dr. Root_CanalCasey Hart are here to the rescue when you start noticing problems with your smile that require immediate attention. Find out the signs and symptoms that might mean that you need root canal therapy, and why this procedure is so important for maintaining a healthy smile.

The most common indication that you may need root canal treatment is a toothache. Some people may only experience minor pain and not think it warrants a trip to the dentist while others may deal with persistent and severe pain. The pain may come and go throughout the day or get worse when biting down or putting pressure on the tooth.

You may also find that the tooth is particularly sensitivity to hot or cold foods and beverages. The gums around the tooth may also be red, tender or swollen. A toothache alone is considered a dental emergency, no matter how mild it may be.

What You Should Do

If you notice any of the symptoms above then it’s time to contact your dentist in Marietta, GA, right away. Tell us about your symptoms over the phone and then a member of our dental staff will arrange an urgent care appointment for you. If symptoms are severe enough we may tell you to come right into the office.

If you are in severe pain you may choose to temporarily alleviate pain with over-the-counter painkillers or by applying an ice pack to the affected side of the face to ease your symptoms until your appointment.

What will a root canal do?

Our dentist will run x-rays to look at the health of the dental pulp, a structure inside the tooth that is made up of nerves, blood vessels and connective tissue. If the pulp is infected or inflamed, we will need to perform root canal treatment to remove the pulp and to clean out the inside of the tooth to prevent bacteria from spreading further into the tooth, as well as to nearby bone and other teeth.

A root canal is performed under local anesthesia, so the treatment area will be completely numb. Once the dental pulp has been extracted and the inside of the tooth has been disinfected we will apply a special material inside the roots and the tooth to support the structure and also to prevent another infection from occurring. After root canal therapy, your dentist may also decide to place a dental crown over the tooth for protection.

If you are dealing with a toothache or other dental issues in Marietta, GA, then don’t hesitate to call our office right away. We will make sure that you get the dental care you need.

RootCanalsareaSafeWaytoSaveTeeth

Every year U.S. dentists perform around 25 million root canal treatments and save countless teeth from the ravages of decay. But if you search "root canal" on the Internet, you might encounter an unsettling charge against this tooth-saving treatment—that it causes cancer.

Root canal treatments are routinely used when tooth decay has infected the pulp, the innermost layer of a tooth. During the procedure, we access the pulp and remove all the infected tissue. We then fill the empty pulp and root canals, seal the access hole and later crown the tooth to prevent further infection. Without this intervention, the decay can continue to advance toward the roots and supporting bone, putting the tooth in imminent danger of loss.

So, is there any credibility to this claim that root canal treatments cause cancer? In a word, no: there's no evidence of any connection between root canal treatments and cancer—or any other disease for that matter. On the contrary: root canals stop disease.

As with other types of urban legends and internet hype, the root canal-cancer connection may have arisen from another discredited idea from the early 20th Century. A dentist named Weston Price promoted the notion that leaving a "dead" organ in the body led to health problems. From his perspective, a root canaled tooth with its removed pulp tissue fit this criterion.

In the mid-1950s, dentistry thoroughly examined Dr. Weston's theory pertaining to treatments like root canals. The Journal of the American Dental Association devoted an entire issue to it and found after rigorous scientific inquiry that the theory had no validity in this regard. Another study in 2013 confirmed those findings. In fact, the later study instead found that patients who underwent a root canal treatment had a 45 percent reduction in oral cancer risk.

Given the freewheeling nature of the Internet, it's best to speak with a dental professional about your oral health before trusting a post or article you've found online. Not only are they more informed than an unverified online source, they would certainly not knowingly subject you to a procedure to save a tooth at the expense of your health.
