For generations, dentures have helped people avoid the dire consequences of total teeth loss. Now, implant technology is making them even better.
Composed of life-like prosthetic teeth fixed within a plastic or resin gum-colored base, dentures are manufactured to fit an individual patient’s mouth for maximum fit, comfort and performance. But dentures also have a critical drawback—they can’t stop bone loss in the jaw.
Bone is constantly regenerating as older cells dissolve and then are replaced by newer cells. In the jawbone, the forces generated when we chew travel through the teeth to the bone and help stimulate this new cell growth. When teeth are missing, though, the bone doesn’t receive this stimulus and may not regenerate at a healthy rate, resulting in gradual bone loss.
Dentures can’t transmit this chewing stimulus to the bone. In fact, the pressure they produce as they rest on top of the gums may actually accelerate bone loss. Over time then, a denture’s once secure and comfortable fit becomes loose.
In the past, most patients with loose dentures have had them relined with new dental material to improve fit, or have new dentures created to conform to the changed contours of the jaws. But implant technology now offers another alternative.
Implants are in essence a tooth root replacement. Dentists surgically implant a titanium metal post directly into the jawbone that naturally attracts bone cells to grow and adhere to it over time (a process called osseointegration). This not only creates a secure and lasting hold, it can also stop or even reverse bone loss.
Most people know implants as single tooth replacements with a porcelain crown attached to the titanium post. But a few strategically placed implants can also support either removable or fixed dentures. Removable dentures (also called overdentures) usually need only 3 or 4 implants on the top jaw and 2 on the bottom jaw for support through built-in connectors in the dentures that attach to the implants. A fixed bridge may require 4-6 implants to which they are permanently attached.
There are pros and cons for each of these options and they’re both more expensive than traditional dentures. In the long run, though, implant-supported dentures could be more beneficial for your bone health and hold their fit longer.
While the prevention and treatment of tooth decay has improved dramatically over the last half century, it continues to be a major health issue, especially for children. One in four children 5 and younger will develop some form of the disease.
Although tooth decay in children stems from the same causes as in adults — the presence of decay-causing bacteria in plaque, unprotected teeth and the right mix of carbohydrates like sugar left in the mouth — the means by which it occurs may be different. We even define tooth decay differently in children as Early Childhood Caries (ECC), “caries” the dental profession’s term for tooth decay.
ECC highlights a number of cause factors specific to young children, such as: continuous use of a bottle or “sippy cup” filled with juice or other sweetened beverages; at-will breast-feeding throughout the night; use of a sweetened pacifier; or regular use of sugar-based oral medicine to treat chronic illness.
If you noticed sugar as a common denominator in these factors, you’re right. As a primary food source for bacteria, refined sugar is a major trigger for the disease especially if it constantly resides in the mouth from constant snacking or sipping. In fact, it’s the primary driver for a particular pattern of decay known as Baby Bottle Tooth Decay (BBTD). This pattern is specifically linked to sleep-time bottles filled with juice, milk, formula or other sweetened beverages, given to an infant or toddler to help soothe them through the night or during naps.
All these factors cause a cycle of decay. To interrupt that cycle, there are some things you as a parent should do: perform daily hygiene with your child to reduce decay-causing bacteria; reduce the amount and frequency of carbohydrates in the diet, particularly sugar; and protect the teeth by having us apply fluoride or sealants directly to the teeth.
Early tooth decay could affect your child's oral health for years to come. With a little care and vigilance, you improve your chances of avoiding that encounter.

Sometimes dental conditions point to health problems beyond the teeth and gums. An astute dentist may even be able to discern that a person’s oral problems actually arise from issues with their emotional well-being.Â In fact, a visit to the dentist could uncover the presence of two of the most prominent eating disorders, bulimia nervosa or anorexia nervosa.
Here are 3 signs dentists look for that may indicate an eating disorder.
Dental Erosion. Ninety percent of patients with bulimia and twenty percent with anorexia have some form of enamel erosion. This occurs because stomach acid — which can soften and erode enamel — enters the mouth during self-induced vomiting (purging), a prominent behavior with bulimics and somewhat with anorexics. This erosion looks different from other causes because the tongue rests against the back of the bottom teeth during vomiting, shielding them from much of the stomach acid. As a result, erosion is usually more severe on the upper front teeth, particularly on the tongue side and biting edges.
Enlarged Salivary Glands. A person induces vomiting during purging by using their fingers or other objects. This irritates soft tissues in the back of the throat like the salivary glands and causes them to swell. A dentist or hygienist may notice redness on the inside of the throat or puffiness on the outside of the face just below the ears.
Over-Aggressive Brushing. Bulimics are acutely aware of their appearance and often practice diligent hygiene habits. This includes brushing the teeth, especially after a purging episode. In doing so they may become too aggressive and, coupled with brushing right after purging when the minerals in enamel are softened, cause even greater erosion.
Uncovering a family member’s eating disorder can be stressful for all involved. In the long run, it’s best to seek out professional help and guidance — a good place to start is the National Eating Disorders Association (www.nationaleatingdisorders.org). While you’re seeking help, you can also minimize dental damage by encouraging the person to rinse with water (or a little baking soda) after purging to neutralize any acid in the mouth, as well as avoid brushing for an hour.
