Dental implants are now the gold standard for tooth replacement. Why? Because not only do they offer the longest-lasting method of restoring missing teeth, but they also help mitigate one of the greatest problems associated with tooth loss — the loss of underlying bone structure. While standard dental implants have been around since the 1970s, mini-implants are a smaller version of the same technology that have recently come into their own. Here are a few things you should know about them.
Mini-implants rely on the same structure and principles as their larger relatives.
Like standard implants, mini-implants are screw-shaped devices made of titanium which are set into the bone of the jaw. Put in place permanently, they become fixed to the bone itself, which grows around and fuses to the implant. Or, they can be used as temporary anchors for the attachment of other dental work.
Mini-implants are a great option for attaching lower overdentures.
Overdentures (implant-retained dentures) are now considered the standard of care for people who have lost all of their teeth in one or both jaws. But the undesired movement of lower dentures has been a perennial problem for many denture wearers. One key use of mini-implants is to anchor overdentures to the lower jaw. Just two mini-implants provide the stability needed to attach a set of lower dentures sturdily, giving the denture wearer increased dental function — and a restored sense of confidence.
Mini-implants offer some real benefits in orthodontics.
TADS (Temporary Anchorage Devices), another type of mini-implants, are finding increasing use alongside of orthodontic appliances (braces). Braces move teeth by placing small forces on them, which are transmitted by a wire. The wire must be anchored at a “fixed” point: usually, other teeth; but it may cause these teeth to move as well! TADS offer an anchorage point that's truly immovable. They help to speed up orthodontic treatment, and give more accurate control as well.
Placing mini-implants is a relatively simple process.
It's an office procedure done by an experienced clinician, normally under local anesthesia. Most patients tolerate the procedure very well, experiencing only minor discomfort. In some cases, a single two-hour visit is all that's needed for implant placement, and the patient can go home and eat a steak afterward!
Mini-implants may be more economical than you think.
These smaller cousins of standard implants are often easier to place. They save treatment time, and, if you're a denture wearer, they may be compatible with your existing dentures. If your dental situation could benefit from using mini-implants, you should give them serious consideration.
If you would like more information about mini-implants, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine articles “Implant Overdentures for the Lower Jaw,” “The Great Mini-Implant,” and “What are TADS?”
If you have pain in your jaws or related headaches, you may have Temporo-mandibular Joint Disorder, TMD. You are probably wondering what this is — and how it can be treated. If this sounds like something you may have, read on for some answers.
What is TMD? TMD describes a group of disorders or diseases that have the same symptoms, but may have different causes, hence it is known as “The Great Imposter.” Pain in and around the temporo-mandibular joint (TMJ), the jaw joint involved in opening and closing your mouth — is characterized by pain and soreness in the region of one or both joints, ears, jaw muscles and even the sinuses.
How does the temporo-mandibular joint work? You can feel your jaw joints working if you place your fingers in front of your ears and move your lower jaw up and down. On each side the joint is composed of an almond shaped structure at the end of the lower jaw, called the condyle, which fits neatly into a depression in the temporal bone (the bone on the side of your skull near your ear). A small disc between the two bones allows the lower jaw to move forward and sideways. The joints are stabilized by ligaments and moved by muscles, like all your joints.
What is the most common cause of TMD? Many people clench or grind their teeth as a reaction to stress. This is generally a subconscious habit, and can even occur during sleep. Continual tooth grinding habits can cause the muscles to go into spasm, which is the most common cause of TMD pain. Structures associated with the jaws — teeth, air sinuses, and even neck and back muscles — share nerves with the muscles in the joints, so the pain may be felt in those structures too, making the exact source of the pain difficult to diagnose. Symptoms of TMD may limit your ability to open your jaw and talk or eat normally.
What is the treatment for TMD? Treatment will depend on the cause, but generally the first step is to relieve pain and discomfort with heat, mild painkillers, muscle relaxants, a soft diet, and simple jaw exercises. A bite guard may be recommended, which should be custom made in our office; a rigid yet unobtrusive plastic appliance that fits over the biting surfaces of your upper teeth. Properly fitted and adjusted, it aids and causes jaw muscle relaxation by preventing clenching and grinding. It is worn during times of stress when oral habits tend to recur, and can also be worn at night.
If you are suffering from TMD — whether the pain is moderate or severe — schedule an appointment with us to have it evaluated and treated. You can learn more about TMD by reading the Dear Doctor magazine article “TMD: Understanding the Great Imposter.”
If you have ever had tooth decay, you should know:
- Tooth decay is one of the most common of all diseases, second only to the common cold.
- Tooth decay affects more than one-fourth of U.S. children ages 2 to 5, half of those ages 12 to 15, and more than 90 percent of U.S. adults over age 40.
- Tooth decay causes pain, suffering and disability for millions of Americans each year — even more disturbing, tooth decay is preventable.
- If it is not treated, in extreme and rare cases tooth decay can be deadly. Infection in an upper back tooth can spread to the sinus behind the eye, from which it can enter the brain and cause death.
- Tooth decay is an infectious process caused by acid-producing bacteria. Your risk for decay can be assessed in our office with a simple test for specific bacterial activity.
- Three factors are necessary for tooth decay to occur: susceptible teeth, acid-producing bacteria and a diet rich in sugars and refined carbohydrates.
- Babies are not born with decay-causing bacteria in their mouths; the bacteria are transmitted through saliva from mothers, caregivers, or family members.
- Fluoride incorporated into the tooth structure protects teeth against decay by making the enamel more resistant to acid attack.
- Sealants, which close up the nooks and crannies in newly erupted teeth, stop bacterial collection where a toothbrush can't reach. Teeth with sealants have been shown to remain 99 percent cavity-free over six years.
- Restricting sugar intake is important in preventing tooth decay. Your total sugar intake should be less than 50 grams a day (about ten teaspoons) including sugars in other foods. A can of soda may have six teaspoons of sugar — or more!

Statistically speaking, Americans can expect to enjoy a longer life today than at any time in the past. A recent U.S. government interagency study indicated that our oldest citizens are also generally getting healthier and doing better economically. Yet, along with an increased lifespan comes the possibility that at some future time, you or a loved one may undergo treatment for cancer.
There's good news here too: According to the National Cancer Institute, a branch of the National Institutes of Health, both the rate of cancer incidence and the death rate from the disease have been steadily declining. It's true that cancer treatments may cause a variety of oral health problems. But did you know that there are some measures you can take to minimize the discomfort and possible complications from these lifesaving therapies?
Chemotherapy and radiation, two common treatments, work by attacking cancerous cells. However, they can affect normal cells too — including the cells lining the mouth, and the salivary glands. This sometimes results in mouth sores, a dry mouth, and an increased risk of developing dental diseases like tooth decay.
What should you do if you or someone you love needs cancer treatments? The best outcomes can be obtained by a dose of prevention when possible, and by taking a team approach to the treatment.
Oral side effects may be worse if the mouth isn't healthy prior to cancer treatment. So, if there's time, have necessary dental procedures done before treatment begins. During and after cancer therapy, dental surgery should be limited if possible. The first step is to get a complete dental examination, and to develop a treatment plan. It's vitally important to coordinate any dental treatments with an oncologist (cancer specialist).
There are also things a patient can do to help control unpleasant oral side effects. Removing the bacteria that cause tooth decay is more essential now than ever. In addition to thorough brushing, an antibacterial rinse or fluoride gel may be prescribed. To combat the symptoms of dry mouth, it's important to drink plenty of fluids. Chewing gum with Xylitol, or using a mouth rinse or a prescription medication may also be recommended.
It's essential for those having cancer treatment to understand and follow the recommendations of their dentist and doctor. These include taking steps to reduce the chance of complications, and recognizing the warning signs that may indicate a problem.
