After a long struggle with dental disease, you have finally lost the last of your remaining teeth.Â Like over a quarter of Americans in their 60s and 70s, this unfortunate development can have a profound impact on your health and self-image.
While there are a number of advanced methods for replacing lost teeth, there's one tried and true option that's centuries old — the removable denture. It's the option millions of people have chosen to lessen the impact of missing teeth.
Fashioned properly, removable dentures restore the form and function you once had with your natural teeth. The prosthetic (false) teeth are precisely placed in an acrylic, gum-colored base that closely follows the contours of your gums. Because they're removable, they're fairly easy to clean and maintain.
They do have a disadvantage, though, and it's related to bone health after tooth loss. Like other living tissues, bone has a life cycle: as older cells die, new cells form to take their place. The forces your teeth generate when you chew stimulate new bone growth. But without teeth to provide this stimulation, new bone won't keep up the pace of replacement at a healthy rate. As a result you may gradually lose bone, as much as a quarter of its normal width within a year of losing a tooth.
Dentures don't transmit any stimulation to the gum and bone from chewing. Furthermore, the compressive forces transmitted to the gum and underlying bone tissue contributes to bone loss. As the bone continues to diminish, your denture fit becomes looser to the point you will eventually need them relined with new acrylic material or have a new set made.
There is another alternative when patients loose all of their teeth: an implant-supported removable denture. Dental implants can be used to keep the dentures more secure and can also slow or even halt bone loss where the implants are placed. In this case we strategically place a few implants to serve as supports for a removable denture. The denture has connection points that join up with the implants to hold it more securely in place. As few as two implants are needed in the lower jaw, while the upper jaw does better with three or four implants.
Losing all your teeth can be traumatic, but there are effective ways to overcome it. With new technology, the traditional restoration of removable dentures may be the vehicle for achieving that.

If you’ve suffered from problems with your jaw joints, known collectively as temporomandibular disorders (TMDs), then you know how uncomfortable and painful they can be. You may also have heard about the use of Botox injections to ease TMD discomfort.
Before you seek out Botox treatment for TMD, though, you should consider the current research on the matter. Far from a “miracle” treatment, the dental profession is still undecided on the effects of Botox to relieve TMD pain symptoms — and there are other risks to weigh as well.
Botox is an injectable drug with a poisonous substance called botulinum toxin type A derived from clostridium botulinum, a bacterium that causes muscle paralysis. The Food and Drug Administration (FDA) has approved small dose use for some medical and cosmetic procedures, like wrinkle augmentation. The idea behind its use for TMD is to relax the muscles connected to the joint by paralyzing them and thus relieve pain.
The FDA hasn’t yet approved Botox for TMD treatment, although there’s been some use for this purpose. There remain concerns about its effectiveness and possible complications. In the first place, Botox only relieves symptoms — it doesn’t address the underlying cause of the discomfort. Even in this regard, a number of research studies seem to indicate Botox has no appreciable effect on pain relief.
As to side effects or other complications, Botox injections have been known to cause pain in some cases rather than relieve it, as with some patients developing chronic headaches after treatment. A few may build up resistance to the toxin, so that increasingly higher dosages are needed to achieve the same effect from lower dosages. And, yes, Botox is a temporary measure that must be repeated to continue its effect, which could lead to permanent paralyzing effects on the facial muscles and cause muscle atrophy (wasting away) and even deformity.
It may be more prudent to stick with conventional approaches that have well-documented benefits: a diet of easier to chew foods; cold and heat applications; physical therapy and exercises; pain-relief medications and muscle relaxers; and appliances to help control grinding habits. Although these can take time to produce significant relief, the relief may be longer lasting without undesirable side effects.
If you're one of over 30% of Americans who wince in pain when eating and drinking certain foods and beverages, you may have tooth sensitivity. Although there are a number of possible causes, the most common place to look first is tooth dentin.
Lying just under the enamel, dentin consists of tiny tubules that transmit sensations like pressure or temperature variation to the nerves of the inner pulp. The enamel, the gums and a covering on the roots called cementum help dampen these sensations.
But over-aggressive brushing or periodontal (gum) disease can cause the gums to shrink back (recede) and expose the dentin below the gum line; it can also cause cementum to erode from the roots. This exposure amplifies sensations to the nerves. Now when you eat or drink something hot or cold or simply bite down, the nerves inside the dentin receive the full brunt of the sensation and signal pain.
Enamel erosion can also expose dentin, caused by mouth acid in contact with the enamel for prolonged periods. Acid softens the minerals in enamel, which then dissolve (resorb) into the body. Acid is a byproduct of bacteria which live in dental plaque, a thin film of food particles that builds up on teeth due to poor oral hygiene. Mouth acid may also increase from gastric reflux or consuming acidic foods or beverages.
Once we pinpoint the cause of your tooth sensitivity we can begin proper treatment, first and foremost for any disease that's a factor. If you have gum disease, we focus on removing bacterial plaque (the cause for the infection) from all tooth and gum surfaces. This helps stop gum recession, but advanced cases may require grafting surgery to cover the root surfaces.
You may also benefit from other measures to reduce sensitivity:Â applying less pressure when you brush; using hygiene products like toothpastes that block sensations to the dentin tubules or slow nerve action; and receiving additional fluoride to strengthen enamel.
There are effective ways to reduce your tooth sensitivity. Determining which to use in your case will depend on the cause.

Your teeth are meant to last a lifetime. Even with wear and tear from years of eating and biting they can continue to function properly and look attractive well into your senior years.
Teeth are resilient thanks in part to enamel, the hardest substance in the human body. But the gums also contribute to this resilience: besides attractively framing the teeth, they protect the dentin and roots below the enamel covering.
Unfortunately, the gums can shrink back or “recede” from their normal place. Not only does this look unattractive, the recession can also expose teeth to disease and cause tooth sensitivity to temperature changes or biting pressure.
There are a number of causes for gum recession, some of which you may have little control over. If, for example, your teeth come in off center from their bony housing, the gum tissues may not develop around them properly. You might also have inherited a thinner type of gum tissue from your parents: thinner tissues are more delicate and susceptible to recession.
But there are other causes for which you have more control. Over-aggressive brushing (too hard for too long), ironically, does more harm than good as it can injure your gums and cause them to recede. More likely, though, your recession is a direct result of neglecting proper hygiene for your teeth and gums.
When teeth aren't properly cleaned through daily brushing and flossing, a thin film of bacteria and food remnant called plaque builds up on tooth surfaces. This can trigger periodontal (gum) disease, which subsequently causes the gum tissues to detach from the teeth and often recede.
To reduce your risk of gum disease, you should gently but thoroughly brush and floss daily, and visit us for cleanings and checkups at least twice a year. If you have a poor bite (malocclusion), consider orthodontic treatment: malocclusions make it easier for plaque to accumulate and harder to remove.
Above all, if you begin to see signs of gum problems — swelling, bleeding or pain — see us promptly for an examination and treatment. Dealing with these issues early is the best way to ensure your gums continue to do their jobs for the long-term.
Removing a problem tooth (extraction) is a common dental procedure. But not all extractions are alike — depending on the type of tooth, its location and extenuating circumstances, you may need an oral surgeon to perform it.
Fortunately, that's not always the case. Teeth with straight or cone-shaped roots, like an upper front tooth, have a fairly straight removal path. A general dentist first carefully manipulates the tooth loose from the periodontal ligament fibers that help hold it in place (experienced dentists, in fact, develop a “feel” for this process). Once it's loosened from the fibers it's a simple motion to remove the tooth.
But as mentioned before, a “simple extraction” won't work with every tooth or situation. To find out if it can we'll first need to determine the true shape of the tooth and roots, as well as the condition of the supporting bone. We might find any number of issues during this examination that make a simple extraction problematic.
For example, teeth with multiple roots (especially in back) may have complicated removal paths. If the roots themselves are unhealthy and brittle from previous injury or a root canal treatment, they can fracture into smaller pieces during removal. A tooth could also be impacted — it hasn't fully erupted but remains below the gum surface. It's these types of situations that require surgery to remove the tooth.
During a surgical extraction, the oral surgeon will first numb the area with a local anesthetic, as well as a sedative if you have issues with anxiety. They then perform a surgical procedure appropriate for the situation to remove the tooth. More than likely they'll insert bone grafts before closing the site with stitches to deter bone loss (a common occurrence after losing a tooth).
Afterward, your provider may prescribe antibiotics and an antibacterial mouthrinse to ward off infection. You'll also be given care instructions for the extraction site to keep it clean. Any discomfort should subside in a few days and can be managed effectively with a mild anti-inflammatory drug like ibuprofen or aspirin.
It can be overwhelming having a tooth removed. In your dentist's capable hands, however, the experience will be uneventful.
