As a new permanent tooth develops, the roots undergo a process of breakdown and growth. As older cells dissolve (a process called resorption), they’re replaced by newer cells laid down (deposition) as the jaw develops. Once the jaw development ends in early adulthood, root resorption normally stops. It’s a concern, then, if it continues.
Abnormal root resorption most often begins outside of the tooth and works its way in, beginning usually around the neck-like (or cervical) region of the tooth. Also known as external cervical resorption (ECR), the condition usually shows first as pink spots where the enamel is being undermined. As these spots continue to erode, they develop into cavity-like areas.
While its causes haven’t been fully confirmed, ECR has been linked to excessive pressure on teeth during orthodontic treatment, periodontal ligament trauma, teeth-grinding or other excessive force habits, and bleaching techniques performed inside a tooth. Fortunately, ECR is a rare occurrence, and most people who’ve had these problems won’t experience it.
When it does occur, though, it must be treated as quickly as possible because the damage can progress swiftly. Treatment depends on the size and location of the resorption: a small site can often be treated by surgically accessing the tooth through the gum tissue and removing the offending tissue cells. This is often followed with tooth-colored dental material that’s bonded to the tooth to replace lost structure.
A root canal treatment may be necessary if the damage has extended to the pulp, the tooth’s interior. However, there’s a point where the resorption becomes too extensive to save the tooth. In these cases, it may be necessary to remove the tooth and replace it with a dental implant or similar tooth restoration.
In its early stages, ECR may be difficult to detect, and even in cases where it’s been diagnosed more advanced diagnostics like a CBCT scanner may be needed to gauge the extent of damage. In any case, it’s important that you have your teeth examined on a regular basis, at least twice a year. In the rare chance you’ve developed ECR, the quicker it’s found and treatment begun, the better your chances of preserving the tooth.
The 2019 Grammy Awards was a star-studded night packed with memorable performances. One standout came from the young Canadian singer Shawn Mendes, who sang a powerful duet of his hit song "In My Blood" with pop diva Miley Cyrus. But that duo's stellar smiles weren't always quite as camera-ready as they looked that night.
"I had braces for four and a half years," Mendes told an interviewer not long ago. "There's lots and lots and lots of photo evidence, I'm sure you can pull up a few." (In fact, finding one is as easy as searching "Sean Mendes braces.")
Wearing braces puts Mendes in good company: It's estimated that over 4 million people in the U.S. alone wear braces in a typical year—and about a quarter of them are adults! (And by the way: When she was a teenager, Miley Cyrus had braces, too!)
Today, there are a number of alternatives to traditional metal braces, such as tooth-colored braces, clear plastic aligners, and invisible lingual braces (the kind Cyrus wore). However, regular metal braces remain the most common choice for orthodontic treatment. They are often the most economical option, and can be used to treat a wide variety of bite problems (which dentists call malocclusions).
Having straighter teeth can boost your self-confidence—along with helping you bite, breathe, chew, and even speak more effectively. Plus, teeth that are in good alignment and have adequate space in between are easier to clean; this can help you keep your mouth free of gum disease and tooth decay for years to come.
Many people think getting braces is something that happens in adolescence—but as long as your mouth is otherwise healthy, there's no upper age limit for orthodontic treatment. In fact, many celebrities—like Lauren Hutton, Tom Cruise and Faith Hill—got braces as adults. But if traditional braces aren't a good fit with your self-image, it's possible that one of the less noticeable options, such as lingual braces or clear aligners, could work for you.
What's the first step to getting straighter teeth? Come in to the office for an evaluation! We will give you a complete oral examination to find out if there are any problems (like gum disease or tooth decay) that could interfere with orthodontic treatment. Then we will determine exactly how your teeth should be re-positioned to achieve a better smile, and recommend one or more options to get you there.
If you have questions about orthodontic treatment, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “The Magic of Orthodontics” and “Lingual Braces: A Truly Invisible Way to Straighten Teeth.”
If you’re in the initial planning stages for a dental implant, you may already be encountering a number of options to consider. One that may come up is how the visible crown will attach to the metal implant imbedded in the bone.
Generally speaking, implants are composed of two parts: a metal post most often made of titanium placed into the bone that serves as the “root” for the new tooth; and a visible, life-like crown made of dental porcelain that attaches to an abutment on the titanium post. The crown can be attached in one of two ways: either with a small screw through the biting surface of the crown into a receiving hole in the abutment or cemented to it.
The major advantage of a screwed crown is that it allows for easy removal of the crown if needed. While the titanium post can often last a lifetime, porcelain crowns more often need repair or replacement since they receive the brunt of the biting forces in the mouth. A screw-attached crown is much easier to remove than a cemented one.
On the other hand, screwed crowns have a small access hole that must be restored with a tooth-colored filling to help the crown appear natural. This isn’t too great an issue with back teeth but does make achieving a natural appearance in the front more difficult. Cemented crowns look more like a natural tooth and are thus more flexible in achieving the desired appearance.
Besides the possibility the cement may cause gum inflammation or bone loss, the chief detraction from cemented crowns is the difficulty in removing them. Crowns are often damaged in this process so it’s highly likely it will have to be replaced rather than repaired. It’s possible to use weaker cement, but this raises the risk of the crown coming loose at some point from the abutment.
As we plan for your implant, we’ll discuss which type of attachment will work best for you, depending on the tooth to be replaced and other conditions with your oral health. The end result, though, should be the same — a new, natural-looking tooth that serves you well for many years to come.
