Twenty-six percent of American adults between 65 and 74 have lost all their teeth to dental disease. This isn’t an appearance problem only—lack of teeth can also harm nutrition and physical well-being.
Fortunately, we have advanced restorative options that can effectively replace missing teeth. Of these, there’s a tried and true one that’s both affordable and effective: removable dentures.
Dentures are simple in design: a plastic or resin base, colored with a pinkish-red hue to resemble gums to which we attach prosthetic (false) teeth. But while the design concept isn’t complicated, the process for creating and fitting them can be quite involved: they must conform to an individual patient’s jaws and facial structure if they’re going to appear natural.
If you’re considering dentures, here’s some of what it will take to achieve a successful outcome.
Positioning the teeth. The position of the prosthetic teeth on the base greatly determines how natural they’ll appear and how well they’ll function. So, we’ll need to plan tooth placement beforehand based on your facial and jaw structures, as well as photos taken of you before tooth loss. We’ll also consider how large the teeth should be, how far to place them forward or back from the lips, and whether to include “imperfections” from your old look that you see as part of your appearance.
Simulating the gums. While the teeth are your smile’s stars, the gums are the supporting cast. It’s important that we create a denture base that attractively frames the teeth by determining how much of the gums show when you smile, or adding color and even textures to better resemble gum tissue. We can also add ridges behind the upper teeth to support speech.
Balancing the bite. Upper and lower dentures don’t operate in and of themselves—they must work cooperatively and efficiently with each other during eating or speaking. So while appearance matters, the bite’s bite adjustment or balance might matter more. That’s why we place a lot of attention into balancing and adjusting the bite after you receive your dentures to make sure you’re comfortable.
This is a detailed process that we may need to revisit from time to time to make sure your dentures’ fit remains tight and comfortable. Even so, modern advances in this traditional restoration continue to make them a solid choice for total tooth loss.

A loose baby tooth is normal and expected; a loose permanent tooth is quite another matter: it’s an advanced sign of disease that could lead to losing the tooth.
The reasons for its looseness may vary. You may have experienced “primary occlusal trauma,” in which the teeth have experienced a prolonged excessive biting force beyond their tolerance. This can be caused by habitual grinding or clenching the teeth.
You may have also experienced “secondary occlusal trauma”: although the biting forces are within normal ranges, the teeth still can’t handle the stress due to degraded bone support and gum tissue detachment. Clenching habits combined with weakened bone and gums will only accelerate and worsen the damage.
The most frequent cause in adults for loose teeth is secondary trauma from periodontal (gum) disease. Bacterial plaque built up on teeth from poor oral hygiene causes a chronic infection that eventually weakens gum attachment to the teeth. A loose tooth is a late sign of this damage.
Treatment for disease-based loose teeth has a twofold approach. First, we thoroughly clean the tooth, root and gum surfaces of all plaque and calculus (hardened plaque deposits) to reduce the infection and inflammation and restore tissue health. This is often accompanied by antibiotic treatments to reduce bacteria below the gum tissue.
For the loose teeth themselves, we may need to modify the forces against them while the gums and bone heal. One way to lessen the biting force on a tooth is to reshape its and the opposing tooth’s biting surfaces. For extensive looseness we can also splint the affected tooth or teeth with other teeth. Temporarily, we can apply splinting material to the outside of both the loose and stable teeth or cut a small channel into them and apply bonding material to join them. A permanent option is to crown both the affected teeth and nearby stable teeth and fuse the crowns together.
These and other stabilizing techniques, like occlusal night guards to reduce the effects of teeth grinding or orthodontic treatment, will help secure the teeth. Coupled with disease treatment and renewed dental care and hygiene practices, you may be able to keep that loose tooth from being lost.

Porcelain veneers represent one of the best values in cosmetic dentistry, capable of radically changing a person’s smile with little tooth surface preparation. Still, the small amount of tooth enamel usually removed to accommodate them will permanently alter the affected teeth, to the point they will require a veneer or other restoration from then on.
The traditional veneer has remarkable versatility for solving a number of minor cosmetic problems, correcting mild tooth positioning problems and replacing lost or damaged enamel. But to avoid an unnatural bulky appearance, a portion of the tooth enamel must be permanently removed to accommodate them.
In recent years, though, a new concept known as “prepless veneers” has emerged in the field of cosmetic dentistry. Understandably, this new, “drill-free” veneer application has caused a lot of debate among dentists and patients alike, with concerns of bulky, overly-contoured teeth resulting from the technique. But the concept is growing as many well-regarded dentists have incorporated both minimal prep and prepless veneers into their service offerings.
The prepless veneer offers a cosmetic solution that doesn’t alter the tooth permanently. Using techniques such as feathering, which tapers and blends the veneer seamlessly with the tooth at the gum line, we can avoid an unnatural appearance while offering patients a much less invasive outcome.
The main disadvantage of prepless veneers at this time is that they’re not appropriate in every case. In fact, careful patient selection is a key to a successful outcome. For example, relatively large teeth or teeth positioned too far forward don’t work well with an added layer of thickness.
If, on the other hand, you have small, short or worn teeth, or teeth overshadowed by your lips — just to name a few likely scenarios — then you may benefit immensely from prepless veneers without permanent alteration to your teeth. A detailed examination is your first step to finding out if this new technique could provide you with a less-invasive smile makeover.

Along with the gums, your teeth’s roots help stabilize them. Without them your teeth couldn’t handle the normal biting forces you encounter every day. That’s why a rare condition called root resorption must be treated promptly: this gradual breakdown and dissolving of root structure could eventually cause you to lose your tooth.
Resorption is normal in primary (“baby”) teeth giving way for permanent teeth or sometimes during orthodontic treatment. But the form of resorption we’re referring to in permanent teeth isn’t normal, and is highly destructive.
The condition begins in most cases outside the tooth and works its way in, usually at the gum line around the cervical or “neck-like” region of the tooth (hence the term external cervical resorption or ECR). ECR produces pink spots on the teeth in its early stages: these are spots of weakened enamel filled with pink-colored cells that cause the actual damage. The cells create cavity-like areas that can continue to enlarge.
We don’t fully understand what causes ECR, but there seems to be links with excessive force during orthodontics, tooth trauma (especially to the gum ligaments), tooth grinding habits or internal bleaching procedures. However, most people with these problems don’t develop ECR, so the exact mechanism remains a bit of a mystery.
The good news, though, is that we can treat ECR effectively, provided we discover it before it inflicts too much damage. That’s why regular dental visits are important, coupled with your own observation of anything out of the ordinary and immediate dental follow-up.
If the affected area is relatively small, we may be able to remove the cells causing the damage and repair the area with a tooth-colored filling. If it appears the pulp (the tooth’s innermost layer) is involved, we may need to perform a root canal treatment to remove infected tissue and fill the empty space with a special filling. You may also need other procedures to reduce the chances of gum recession around the affected tooth.
Proactive dental care is your best insurance against losing a tooth to root resorption. So keep an eye on your teeth and see your dentist regularly to keep your teeth and gums healthy.
