Baby (primary) teeth look and function much like their permanent counterparts. Besides having a visible crown, they also have roots that maintain contact with the jawbone.
But there are some differences, the biggest one being the normal process whereby primary tooth roots dissolve or, in dental terms, resorb. Root resorption eventually leads to the tooth coming loose to make way for the permanent tooth.
Adult tooth roots can also resorb — but it's decidedly not normal. If adult root resorption isn't promptly treated, it could also lead to tooth loss — but there won't be an incoming tooth to take its place.
Although it can begin inside a tooth, adult root resorption usually begins on the outside. One type, external cervical resorption (ECR), begins around the neck-like area of the tooth not far below the gum line. Its initial signs are small pink spots where the tooth enamel has eroded; those pink cells within the space are doing the damage.
We don't fully understand the mechanism behind ECR, but there are some factors that often contribute. People with periodontal ligament damage or trauma, sometimes due to too much force applied during orthodontic treatment, have a high risk of ECR. Some bleaching techniques for staining inside a tooth may also be a factor.
The key to treating ECR is to detect it as early as possible before it does too much root damage. Regular checkups with x-rays play a pivotal role in early detection. Advanced stages of ECR might require more advanced diagnostics like a cone beam computed tomography (CBCT) scan to fully assess the damage.
If the lesion is small, we can surgically remove the cells causing the damage and fill the site with a tooth-colored filling. If ECR has spread toward the pulp, the tooth's inner nerve center, we may also need to perform a root canal treatment.
Either of these methods intends to save the tooth, but there is a point where the damage is too great and it's best to remove the tooth and replace it with a life-like dental implant or other restoration. That's why it requires vigilance through regular, semi-annual dental visits to detect the early signs of root resorption before it's too late.

Like other healthcare providers, dentists have relied for decades on the strong pain relief of opioid (narcotic) drugs for patients after dental work. As late as 2012, doctors and dentists wrote over 250 million prescriptions for these drugs. Since then, though, those numbers have shrunk drastically.
That’s because while effective, drugs like morphine, oxycodone or fentanyl are highly addictive. While those trapped in a narcotic addiction can obtain drugs like heroine illicitly, a high number come from prescriptions that have been issued too liberally. This and other factors have helped contribute to a nationwide epidemic of opioid addiction involving an estimated 2 million Americans and thousands of deaths each year.
Because three-quarters of opioid abusers began their addiction with prescription pain medication, there’s been a great deal of re-thinking about how we manage post-procedural pain, especially in dentistry. As a result, we’re seeing a shift to a different strategy: using a combination of non-steroidal anti-inflammatory drugs (NSAIDs), particularly ibuprofen and acetaminophen, instead of a prescribed narcotic.
These over-the-counter drugs are safer and less costly; more importantly, though, they don’t have the high addictive quality of an opioid drug. A 2013 study published in the Journal of the American Dental Association (JADA) showed that when two NSAIDs were used together, the pain relief was greater than either drug used individually, and better than some opioid medications.
That’s not to say dentists no longer prescribe opioids for pain management following dental work. But the growing consensus among dental providers is to rely on the double NSAID approach as their first-line therapy. If a patient has other medical conditions or the NSAIDs prove ineffective, then the dentist can prescribe an opioid instead.
There’s often hesitancy among dental patients on going this new route rather than the tried and true opioid prescription. That’s why it’s important to discuss the matter with your dentist before any procedure to see which way is best for you. Just like you, your dentist wants your treatment experience to be as pain-free as possible, in the safest manner possible.
Everyone has to face the music at some time — even John Lydon, former lead singer of The Sex Pistols, arguably England’s best known punk rock band. The 59-year old musician was once better known by his stage name, Johnny Rotten — a brash reference to the visibly degraded state of his teeth. But in the decades since his band broke up, Lydon’s lifelong deficiency in dental hygiene had begun to cause him serious problems.
In recent years, Lydon has had several dental surgeries — including one to resolve two serious abscesses in his mouth, which left him with stitches in his gums and a temporary speech impediment. Photos show that he also had missing teeth, which, sources say, he opted to replace with dental implants.
For Lydon (and many others in the same situation) that’s likely to be an excellent choice. Dental implants are the gold standard for tooth replacement today, for some very good reasons. The most natural-looking of all tooth replacements, implants also have a higher success rate than any other method: over 95 percent. They can be used to replace one tooth, several teeth, or an entire arch (top or bottom row) of teeth. And with only routine care, they can last for the rest of your life.
Like natural teeth, dental implants get support from the bone in your jaw. The implant itself — a screw-like titanium post — is inserted into the jaw in a minor surgical operation. The lifelike, visible part of the tooth — the crown — is attached to the implant by a sturdy connector called an abutment. In time, the titanium metal of the implant actually becomes fused with the living bone tissue. This not only provides a solid anchorage for the prosthetic, but it also prevents bone loss at the site of the missing tooth — which is something neither bridgework nor dentures can do.
It’s true that implants may have a higher initial cost than other tooth replacement methods; in the long run, however, they may prove more economical. Over time, the cost of repeated dental treatments and periodic replacement of shorter-lived tooth restorations (not to mention lost time and discomfort) can easily exceed the expense of implants.
That’s a lesson John Lydon has learned. “A lot of ill health came from neglecting my teeth,” he told a newspaper reporter. “I felt sick all the time, and I decided to do something about it… I’ve had all kinds of abscesses, jaw surgery. It costs money and is very painful. So Johnny says: ‘Get your brush!’”
We couldn’t agree more. But if brushing isn’t enough, it may be time to consider dental implants.

Think you’re too old to have your teeth straightened? In reality, healthy teeth can be moved at any age to better positions. For the many adults who have some form of malocclusion (bad bite), orthodontics is still a viable option even in later years.
As important as it is to self-image and confidence, treating misaligned teeth can benefit you more than just improving your smile. Misaligned teeth may be harder to keep clean, setting up a mouth environment advantageous to the development of tooth decay or periodontal (gum) disease, the risks of both rising with age. And normally aligned teeth are easier to chew with than those misaligned.
Age isn’t the determining factor for whether you’re a good candidate for orthodontics — but your dental health is. Gum disease in particular can cause supporting bone loss, which can complicate orthodontic treatment. It’s important then that we first perform a complete oral examination and attempt to treat problems such as decay or gum disease first before attempting tooth movement.
What type of orthodontic treatment you’ll need will depend on the type of malocclusion you have and its relationship to the way your jaws fit together. Because your adult jaws have fully developed you may need orthognathic (“jaw straightening”) surgery to address certain advanced forms of malocclusion. If your bite problems aren’t that severe (the majority of situations) they can be treated with braces or, an increasingly popular alternative, clear aligners. These customized clear plastic trays are nearly invisible compared to metal braces and are effective for most patients.
Following the completion of tooth movement and other bite procedures, you will most likely need to wear a retainer to help prevent the teeth from reverting to their older positions. You may need to wear the retainer for a longer period than a younger patient, or perhaps indefinitely. Even with this mild inconvenience, though, you’ll still experience the positive effects of healthier and better functioning teeth and a great new smile.

Nothing grabs your attention like a sharp tooth pain, seemingly hitting you out of nowhere while you’re eating or drinking. But there is a reason for your sudden agony and the sooner you find it out, the better the outcome for your oral health.
To understand tooth sensitivity, we need to first look at the three layers of tooth anatomy. In the center is the pulp filled with blood vessels and nerve bundles: it’s completely covered by the next layer dentin, a soft tissue filled with microscopic tubules that transmit sensations like pressure or temperature to the pulp nerves.
The third layer is enamel, which completely covers the crown, the visible part of a tooth. Enamel protects the two innermost tooth layers from disease and also helps muffle sensations so the tooth’s nerves aren’t overwhelmed. The enamel stops at about the gum line; below it the gums provide similar protection and sensation shielding to the dentin of the tooth roots.
Problems occur, though, when the dentin below the gums becomes exposed, most commonly because of periodontal (gum) disease. This bacterial infection caused by dental plaque triggers inflammation, which over time can weaken gum tissues and cause them to detach and shrink back (or recede) from the teeth. This can leave the root area vulnerable to disease and the full brunt of environmental sensations that then travel to the nerves in the pulp.
Tooth decay can also create conditions that cause sensitivity. Decay begins when certain oral bacteria multiply and produce higher than normal levels of acid. The acid in turn dissolves the enamel’s mineral content to create holes (cavities) that expose the dentin. Not treated, the infection can eventually invade the pulp, putting the tooth in danger of being lost unless a root canal treatment is performed to remove the infection and seal the tooth from further infection.
So, if you begin experiencing a jolt of pain while eating or drinking hot or cold foods or beverages, see your dentist as soon as possible to diagnose and treat the underlying cause. And protect your teeth from dental disease by practicing daily brushing and flossing, as well as seeing your dentist for regular dental cleanings and checkups. Don’t ignore those sharp pains—your teeth may be trying to tell you something.
