With their durability, versatility and life-likeness, there’s no doubt dental implants have revolutionized teeth replacement. If you’re considering dental implants, however, there are some issues that could impact how and when you receive implants, or if you should consider another type of restoration.
Cost. Dental implants are initially more expensive than other tooth restorations, especially for multiple tooth replacement. However, be sure you consider the projected cost over the long-term, not just installation costs. Because of their durability, implants can last decades with little maintenance cost. In the long run, you may actually pay more for dental care with other types of restorations.
Bone health. Dental implants depend on a certain amount of bone to properly situate them for the best crown placement. If you’ve experienced extensive bone loss, however, there may not be enough to support the implant. This can often be overcome with grafting — immediately after extraction, at the time of implantation or a few months before implantation — to encourage bone growth. In some cases, though, bone loss may be so extensive you may need to consider an alternative restoration.
Gum Health. While implants themselves are impervious to infection, they’re supported by gum and bone tissues that can be affected. Infected tissues around an implant could eventually detach and lead to implant failure. If you have periodontal (gum) disease, we must first bring it under control and render your gums infection-free before installing implants. It’s also important to maintain effective oral hygiene and regular dental cleanings and checkups for optimum implant health.
Complications from osteoporosis. People with osteoporosis — in which the bones lose bone density and are more prone to fracture — are often treated with drugs known as bisphosphonates. In less than 1% of cases of long-term use, a patient may develop osteonecrosis in which the bone in the jaw may lose its vitality and die. As with bone loss, this condition could make implant placement difficult or impractical. Most dentists recommend stopping treatment of bisphosphonates for about three months before implant surgery.
If you have any of these issues or other complications with your oral health, be sure to discuss those with us before considering dental implants. With proper planning and care, most of these difficulties can be overcome for a successful outcome.

Cavities used to be nothing to smile about, but thanks to advances in technology, tooth-colored fillings have made repair of decayed teeth so natural, they're invisible. Now you no longer need to feel self-conscious about that unsightly flash of silver when you talk or laugh. While silver amalgam fillings were once the preferred option for tooth restoration filling materials, tooth-colored “composite resins” have gained popularity as a safe and effective alternative to treat new cavities or to replace old silver fillings.
A Better Alternative: Consumer demand for tooth-colored (metal free) restorations as well as the dental profession's desire to preserve as much natural tooth structure as possible has led to the development of special “adhesive” tooth-colored materials. Besides the aesthetic advantages over amalgam fillings, tooth-colored fillings require the removal of less tooth structure. While traditional silver fillings often crack or leak over time, composite resin fillings bond directly to tooth structure and actually reinforce and strengthen it while creating a natural looking smile.
The Choice is Yours: You can choose to replace unsightly silver fillings with tooth-colored ones to enhance their cosmetic appearance. Although concern has been expressed over the mercury content in older silver fillings, years of research cited by the American Dental Association has found that traditional amalgam fillings are safe. Unless you have cracks or damage to your current amalgam fillings or have other concerns regarding your dental health, replacing silver fillings is a matter of personal preference.
Cost: Although composite resin fillings may cost slightly more than silver fillings, they are very durable and may be more cost-effective in the long run.

Among the “to-do” items on your pre-dive checklist like “Pack wetsuit” or “Fill scuba tanks,” be sure to add one other: “Check my dental health status.”
While that may seem like an odd concern, the changes in atmospheric pressure you encounter while diving (or flying, for that matter) could amplify oral sensitivity and intensify pain if you have pre-existing teeth or jaw problems.
The reason for this is the effect of basic physics on the body. All anatomical structures, including organs, bones and muscles, equalize external pressures the body encounters. We don’t notice this at normal atmospheric pressure, but when we encounter an extreme — either lower pressure during air flight or higher pressure during a scuba dive — we may feel the effects of the pressure on any structure with a rigid-walled surface filled with either air or fluid. These structures can’t equalize the pressure as fast as other areas, resulting in pain or discomfort. This is known medically as “barotrauma,” or more commonly as a “squeeze.”
One structure in particular could have an effect on your upper teeth and jaws: the sinus cavities of the skull, particularly the maxillary sinuses just below the eyes. Their lower walls are right next to the back teeth of the upper jaw and, more importantly, share the same nerve pathways. It’s quite possible, then, for pain from one area to be felt in the other, commonly known as “referred pain.” A toothache could then be felt in the sinus region, and vice-versa.
During a squeeze, then, pain levels from existing problems in the teeth and jaws that were previously tolerable (or even unnoticed) may well become amplified as the pressure from the sinus cavity impinges upon the jaw. That dull toothache you’ve been having may suddenly become excruciating at 30,000 feet — or 30 meters under the surface.
That’s why it’s important to see us if you’ve experienced any signs of tooth decay, gum disease or TMD, including pain, before your next dive or air flight. And, if you encounter any significant pain while flying or diving, be sure you consult with us as soon as possible when you return. Taking action now could help you avoid a miserable, and potentially dangerous, flying or diving experience in the future.

Many people use a mouthrinse as part of their daily oral hygiene. If you’d also like to include a mouthrinse in your regimen, the kind you choose will depend on what you want it to do for you.
If your main desire is fresh breath, then a cosmetic rinse that imparts a minty smell to the mouth should fit the bill. That, however, is all they do — cosmetic mouthrinses don’t contribute to oral health beyond your personal satisfaction that your breath is free of bad odors. But, if you want more — added protection against dental disease, for example — then you’ll need to consider a therapeutic mouthrinse.
Therapeutic mouthrinses are usually described as anti-cariogenic (prevents decay) or anti-bacterial, and include both over-the-counter (OTC) and prescription rinses. Their purpose is to either strengthen teeth or reduce the mouth’s bacterial levels. Of the OTC variety, most contain a small amount of sodium fluoride, which can strengthen tooth enamel. They’ve proven highly effective: a number of studies show using a sodium fluoride mouthrinse in conjunction with brushing and flossing reduces the chances of new cavities forming.
A number of OTC rinses also have an anti-bacterial effect, usually provided by active ingredients such as triclosan, zinc or essential oils like menthol. Even a slight reduction in bacteria can help lessen the chances of gingivitis (gum inflammation), an early form of periodontal (gum) disease. Reducing bacteria levels may also help alleviate bad breath.
Some individuals, though, have higher than normal levels of bacteria, or a systemic weakness in fighting certain bacterial strains. If this is your case, you might benefit from a prescribed mouthrinse intended to lower bacterial levels. Most prescription mouthrinses contain chlorhexidine, which has been amply demonstrated as an effective anti-bacterial control of tooth decay and gum disease. Chlorhexidine prevents bacteria from adhering to the teeth and so disrupts plaque buildup, the main cause of dental disease. Its prolonged use will result in the dark staining of teeth in some people, but this can be removed during dental cleanings and teeth polishing. Long-term use is generally not preferred compared to getting the proper attention from regular cleanings and examinations.
If you would like more advice on adding a mouthrinse to your daily hygiene regimen, especially to help reduce your risk of dental disease, please feel free to discuss this with us at your next checkup. Regardless of which type of mouthrinse you choose, they should always be used as a complement to daily brushing and flossing, along with regular dental cleanings and checkups.
