Although highly preventable, total tooth loss continues to affect millions of people worldwide, harming their nutrition, health and social standing. In the United States alone, a quarter of adults between 65 and 74 suffer from total tooth loss.
Fortunately, there are a number of ways to restore lost teeth, including fixed bridgework and dental implants. These fixed solutions, though, can put a strain on finances; implants in particular require a minimum amount of bone in the jaw, which may not be present in people with extensive tooth loss. In these cases, removable dentures, time-tested and affordable, are a viable option.
While the technology is simple, adaptable and effective, creating custom-fitted dentures is a painstaking process. It begins with an impression mold of the patient’s jaw ridges that once supported the natural teeth. A dental lab technician uses the impression to fashion a life-like plastic resin base, making sure the final dimensions won’t interfere with the patient’s cheeks, lips, and jaw movement.
The prosthetic (artificial) teeth, each chosen to match the patient’s facial structure and past appearance, are then carefully positioned on the base. Teeth positioning on each denture arch must also balance with the opposing arch to assure a good bite. Once delivered, the dentist may make other adjustments to assure they fit comfortably within the patient’s mouth.
Dentures also require regular care and maintenance to ensure a continuing good fit and an overall healthy mouth. Your gums will still be susceptible to disease, so cleaning and maintaining both your dentures and the mouth’s soft tissues is an ongoing necessity.
The lack of natural teeth can also lead to more bone loss, which can cause the dentures to lose their accurate fit and make them uncomfortable to wear. To remedy this, we can add more resin material to the dentures to refit them or, in extreme cases of poor fit, create a new denture to match current gum contours. Alternatively, we can install a few dental implants that will support the denture instead of the gum ridges, which would inhibit further bone loss.
To learn whether dentures could be a good option for you, we’ll first need to conduct a thorough examination of your mouth. It could be this original tooth replacement system will bring back the teeth and smile you’ve lost.

Eating disorders cause more than psychological harm. The binge-purge cycle of bulimia or the self-starvation patterns of anorexia can also injure the physical body, especially the mouth.
For example, nine in ten people with bulimia will experience tooth enamel erosion from stomach acid entering the mouth from induced vomiting. Although purging is less frequent with anorexic patients, one in five will also develop erosion.
An eating disorder isn't the only reason for enamel erosion: you can have high acid levels from over-consuming sodas, energy drinks or certain foods, or not properly brushing and flossing every day. But erosion related to an eating disorder does produce a distinct pattern in the teeth. When a person vomits, the tongue moves forward and presses against the bottom teeth, which somewhat shields them from acid contact. This can create less erosion in the lower front teeth than in others.
Eating disorders can cause other oral effects. Stomach acid contact can eventually burn and damage the mouth's soft tissues. The salivary glands may become enlarged and cause puffiness along the sides of the face. The use of fingers or other objects to induce gagging can injure and redden the back of the throat, the tongue and other soft tissues.
It's important to stop or at least slow the damage as soon as possible. To do so requires both a short– and long-term strategy. In the short-term, we want to neutralize mouth acid as soon as possible after it enters the mouth, especially after purging. Rather than brushing, it's better to rinse out the mouth with water or with a little added baking soda to neutralize the acid. This will at least help reduce the potential damage to enamel.
In the long-term, though, we need to address the disorder itself for the sake of both the person's overall well-being and their oral health. You can speak with us or your family physician about options for counseling and therapy to overcome an eating disorder. You may also find it helpful to visit the website for the National Eating Disorders Association (nationaleatingdisorders.org) for information and a referral network.

Dental implants are today’s closest restorative facsimile to natural teeth. And they’re versatile: not only can they replace single teeth but they can also support bridges or dentures.
But since one of their crucial components is made of metal, are you out of luck obtaining this state-of-the-art dental restoration if you have a metal allergy?
The answer is: probably not—it’s rare for implants to cause an allergic reaction. Still, metal allergies can be a potential problem within your mouth as with other areas of health.
An allergy originates from the body’s necessary response to potentially harmful microorganisms or substances. Sometimes, however, this response becomes chronic and exaggerated, creating an allergy. People can have allergies to nearly anything with responses ranging from a minor rash to a potentially life-threatening multi-organ system shutdown (anaphylactic shock).
A small number of people have allergies to particular metals. One of the most common is nickel, which affects an estimated 17% of women and 3% of men; cobalt and chromium are also known to cause allergies. Consumer exposure, particularly metal contact with the skin through jewelry or clothing, is the most prevalent, but not the most concerning. That’s reserved for metal allergies related to medical devices like coronary stents or hip and knee prostheses. And in dentistry, there are rare occasions of inflammation or rashes from metal amalgam fillings.
Which brings us to dental implants: the main metal post that’s inserted into the jawbone is usually made of titanium. It’s the metal of choice for two reasons: it’s bio-compatible, meaning the body normally accepts its presence; and it’s osteophilic, which means bone cells readily grow and adhere to it, a major reason for implant durability.
While it’s possible for someone to have an allergy and subsequent reaction to implants with titanium, the occurrences appear to be extremely low. In one study of 1,500 patients, titanium allergies were estimated to be a factor in implant failures in less than 1% of those studied.
Even so, if you have known metal allergies you should make sure your dentist knows. Being aware of all the facts will help them recommend the best tooth replacement choice for you—and hopefully it will be dental implants.
