People have depended on dentures for generations—and they still do. That's because they work, both in restoring dental function and a smile marred by missing teeth.
But they have one major drawback related to bone health. That's because living bone has a life cycle: as older cells die, new ones form to take their place. The pressure generated when we chew stimulates this growth. But when this stimulus goes missing along with the teeth, the cell replacement rate slows and bone volume and density gradually diminishes.
Traditional dentures can't transmit this chewing pressure stimulus. And because they rest directly on the gum ridges, they can adversely affect the underlying bone and actually accelerate bone loss.
But implant technology potentially solves this bone loss problem with dentures by using implants rather than the gums to support them. It's a two-fold benefit: first, the implants relieve much of the irritation to the gums and bone caused by traditional dentures. Primarily, though, the implants themselves can slow or even stop continuing bone loss.
Most implants are made of titanium, not only because it's compatible with the body, but also because it has an affinity with bone. Over time bone cells grow on the titanium post imbedded in the jawbone. This process not only creates stability and durability, it can improve bone health.
In recent years dentists have incorporated implants with dentures to create two exciting treatment options. With one option, the dentist installs two or more implants in the jaw, to which a specially fitted removable denture can be attached. You would still have the ease of removing the denture for cleaning, while gaining greater stability and a reduced risk of bone loss.
The other option is a fixed denture (or bridge) attached permanently to implants. For this option, a patient's jawbone must be adequate and healthy enough to support at least four to six implants. A fixed denture is also often costlier and more complex than a removable denture, but it can feel more like real teeth. It also promotes better bone health too.
Although both options are more expensive than traditional dentures, they can pay dividends for long-term dental health. Implants could help you enjoy your new dentures and resulting smile for a long time to come.

Like other healthcare providers, your dentist keeps records of your ongoing care. These include not only their written notes but also x-ray imaging, frequency of visits and cleanings, and any medical information that could affect your care. What’s more, they have a legal obligation to maintain these records.
Your dental records help guide decisions about your care. In that regard, you should consider something else—you may need to change providers: your dentist retires or you move; your dentist isn’t in your new insurance network; or, unfortunately, you have an “irreconcilable” difference with your provider.
If that happens, it’s very important your dental records find their way to your new provider. Here are 3 reasons why.
Your individual dental history. Each person’s dental situation and needs are unique. Your past records help clue in your new dentist about your past history and current needs, which will help guide how they treat you.
Time and money. Your dental records contain x-rays or other diagnostic information about your oral condition, including preparations for any upcoming dental work. If you change dentists before completing that treatment, your new dentist may have to start over with new diagnostic tests if they don’t have this previous data. It could cost you more money and make you wait longer for a needed procedure.
Coordinating dental care with your general health. Your mouth isn’t isolated from the rest of your body, and some dental treatment measures could affect other health conditions (and vice-versa). If your new dentist knows other health issues you may have from your previous records, it can help ensure you’re getting dental treatment appropriate to your overall health.
For the most streamlined transition between providers, it’s important your dental records follow you. You’re entitled to having those records transferred, and, if you’re uncomfortable asking yourself, your new provider can obtain them for you. Just be sure to ask.

Tooth decay and periodontal (gum) disease pose the most common dangers to dental health. But there are some rare conditions that can also place teeth at risk to be on the lookout for during regular dental checkups.
One such condition is root resorption in an adult tooth, in which the root itself or its surface breaks down and is absorbed by the body. Resorption occurs naturally in a primary (“baby”) tooth so it can loosen and give way for an incoming permanent tooth. Â Resorption still occurs in a limited form with young permanent teeth but should eventually stop.
Sometimes, though, it doesn’t, either from the inside of the tooth out (internal resorption) or more often from the outside in, usually around the neck-like (or “cervical”) portion of the tooth. This more common occurrence, External Cervical Resorption (ECR), can first appear as pink spots on the enamel and then progress into cavity-like areas. If not found and treated promptly, damage can occur quickly and lead to tooth loss.
We don’t fully understand the exact nature and causes for ECR, but we have identified risk factors for its development. Excessive orthodontic force on the teeth or any other trauma can cause damage to the periodontal ligament (which holds teeth in place with the jaw bone). Teeth grinding habits and some dental procedures like internal tooth whitening can also be risk factors.That being said, though, the vast majority of people who experience these issues don’t develop ECR.
Although the causes aren’t fully understood, we can still treat it: the key to success is early detection. You probably won’t notice early signs of ECR, but we can often detect spots from routine x-rays. We can then remove the tissue cells within the lesions causing the damage and restore the area with a tooth-colored filling material. If ECR has extended near the tooth’s interior pulp layer, then a root canal treatment may be needed.
Needless to say, the more extensive ECR occurs in the roots, the less likely the tooth can be saved and may need to be extracted. It’s important, therefore, to maintain regular dental checkups (at least twice a year) to increase your chances of catching a developing problem early.

Periodontal (gum) disease is as common as it is destructive. Almost half of all adults 30 and older have some form—and those numbers increase to nearly three-quarters by age 65.
Fortunately, we have effective ways to treat this bacterial infection, especially if we catch it early. By thoroughly removing all plaque, the disease-causing, bacterial biofilm that accumulates on tooth surfaces, we can stop the infection and help the gums return to normal.
Unfortunately, though, you're at a greater risk for a repeat infection if you've already had gum disease. To lower your chances of future occurrences, we'll need to take your regular dental exams and cleanings to another level.
Although everyone benefits from routine dental care, if you've had gum disease you may see these and other changes in your normal dental visits.
More frequent visits. For most people, the frequency norm between dental cleanings and exams is about six months. But we may recommend more visits for you as a former gum disease patient: depending on the advancement of your disease, we might see you every three months once you've completed your initial treatment, and if your treatment required a periodontist, we may alternate maintenance appointments every three months.
Other treatments and medications. To control any increases in disease-causing bacteria, dentists may prescribe on-going medications or anti-bacterial applications. If you're on medication, we'll use your regular dental visits to monitor how well they're doing and modify your prescriptions as needed.
Long-term planning. Both dentist and patient must keep an eye out for the ongoing threat of another gum infection. It's helpful then to develop a plan for maintaining periodontal health and then revisiting and updating that plan as necessary. It may also be beneficial to perform certain procedures on the teeth and gums to make it easier to keep them clean in the future.
While everyone should take their oral health seriously, there's even greater reason to increase your vigilance if you've already had gum disease. With a little extra care, you can greatly reduce your chances of another bout with this destructive and aggressive disease.

As permanent teeth gradually replace primary (“baby”) teeth, most will come in by early adolescence. But the back third molars—the wisdom teeth—are often the last to the party, usually erupting between ages 18 and 24, and the source of possible problems.
This is because the wisdom teeth often erupt on an already crowded jaw populated by other teeth. As a result, they can be impacted, meaning they may erupt partially or not at all and remain largely below the gum surface.
An impacted tooth can impinge on its neighboring teeth and damage their roots or disrupt their protective gum attachment, all of which makes them more susceptible to tooth decay or periodontal (gum) disease. Impacted teeth can also foster the formation of infected cysts that create areas of bone loss or painful infections in the gums of other teeth.
Even when symptoms like these aren’t present, many dentists recommend removing the wisdom teeth as a preemptive measure against future problems or disease. This often requires a surgical extraction: in fact, wisdom teeth removal is the most common oral surgical procedure.
But now there’s a growing consensus among dentists that removing or not removing wisdom teeth should depend on an individual’s unique circumstances. Patients who are having adverse oral health effects from impacted wisdom teeth should consider removing them, especially if they’ve already encountered dental disease. But the extraction decision isn’t as easy for patients with no current signs of either impaction or disease. That doesn’t mean their situation won’t change in the future.
One way to manage all these potentialities is a strategy called active surveillance. With this approach, patient and dentist keep a close eye on wisdom teeth development and possible signs of impaction or disease. Most dentists recommend carefully examining the wisdom teeth (including diagnostic x-rays and other imaging) every 24 months.
Following this strategy doesn’t mean the patient won’t eventually have their wisdom teeth removed, but not until there are clearer signs of trouble. But whatever the outcome might be, dealing properly with wisdom teeth is a high priority for preventing future oral health problems.
