Thanks to treatments like chemotherapy and radiation, your chances of surviving cancer are greater than ever. These treatments, however, often produce unwelcome side effects. Treating throat or oral cancer, for example, could damage your mouth's salivary glands or bone.
Saliva is essential to oral health, providing antibodies to curb the growth of disease-causing bacteria and neutralizing acid, which can erode enamel. But salivary glands damaged during cancer treatment may not be able to produce enough saliva. The resulting “dry mouth” creates an environment conducive to bacterial growth and elevated acid levels.
You can help reduce the effects of dry mouth during your treatment (and after, if the damage is permanent) by drinking more water or by using substances that stimulate saliva. Cutting back on acidic foods and beverages will also help lower your mouth's acidity. And be sure to keep up daily oral hygiene and regular dental visits.
The more ominous threat to oral health during cancer treatment, though, is osteoradionecrosis. This occurs when radiation targets specific areas of bone. The bone can lose blood supply and living cellular tissue, which inhibit its ability to heal or replenish itself. If this occurs in the jawbone of teeth that may be lost, the bone tissue could be adversely affected during healing.
Depending on your treatment needs, your risk for osteoradionecrosis might be unavoidable if teeth are to be lost. It's important we discuss that risk because it could impact future dental treatment. In the worst case, before cancer treatment, we may not be able to save affected teeth and your restorative options might be limited.
If your risk of osteoradionecrosis is minimal, though, we may be able to restore any resulting damaged or missing teeth with a wide range of options like dental implants or crowns before or after your cancer treatment.
As with other aspects of health, taking care of your teeth and gums while undergoing cancer treatment can be challenging; some problems may be unavoidable. But with a proper dental treatment plan during and after chemotherapy and radiation, we can minimize those problems and help to eventually restore your smile.
What makes a beautiful smile? The teeth, of course: bright, evenly shaped and precisely aligned with each other. But your teeth can be as perfect as can be and your smile will still appear unattractive.
The reason? Your gums show more than they should when you smile.
What's considered a gummy smile is largely a matter of perception that can vary from person to person. As a rule of thumb, though, we consider a smile “gummy” if four millimeters (mm) or more of the gums show.
Fortunately, we can minimize the gums' prominence and make your smile more attractive. But what methods we use will depend on why your gums stand out. And it's not always because of the gums themselves.
It could be your teeth didn't erupt normally during dental development. Mature crown (the visible part of the tooth) length is normally about 10 mm with a width about 75-85% of that. But an abnormal eruption could result in teeth that appear too short, which can make the gums stand out more. We can correct this with a surgical procedure called crown lengthening in which we remove excess gum tissue and, if necessary, reshape the underlying bone to expose more of the tooth crown.
Another potential cause is how far your upper lip rises when you smile. Normally the lip rises only enough to reveal about 4 mm of teeth. In some cases, though, it may rise too high and show more of the gums. We can modify lip movement in a number of ways, including Botox injections to temporarily paralyze the lip. A more permanent solution is a lip stabilization procedure. It sounds bad, but it's a fairly simple procedure to surgically reposition the muscle attachments to restrict movement.
Your gummy smile may also result from an upper jaw too long for your facial structure. We can correct this with orthognathic (“ortho” – straighten, “gnathos” – jaw) surgery. During the procedure the surgeon permanently positions the jaw further up in the skull; this will reduce the amount of teeth and gums displayed when you smile.
Discovering the true cause of your gummy smile will determine how we treat it. After a complete oral examination, we can then discuss your options to transform your smile into a more attractive one.

Eating is one of the pleasures — and necessities — of life, but people who suffer from temporomandibular joint disorders (TMD) may find eating no pleasure at all — and they may not be eating the right nutritional balance of foods.
TMD is a collection of conditions that affect the jaw joints, connecting muscles and other related facial structures. If you've been diagnosed with TMD, you're probably not only acquainted with severe pain, but also difficulty opening your jaw as widely as normal. This can make it difficult to chew certain foods.
There are a number of effective treatments for TMD, including thermal therapy (hot or cold packs), joint exercise, medication or surgery (as a last resort). But these treatments often take time to make a noticeable difference. In the meantime, you may still need to change what and how you eat to ensure you're getting the nutrients your body needs.
The overall strategy should be to soften and reduce the chewing size of your food. With fruits and vegetables, you'll want to peel and discard any hard or chewy skins, and then chop the fruit flesh into smaller pieces. Steam or cook vegetables like greens, broccoli or cauliflower until they're soft and then chop them into smaller portions. You might also consider pureeing your fruit (and some vegetables) to make smoothies with ice, milk or yogurt, or vegetable-based soups.
Treat meat, poultry or seafood in much the same way, especially biting sizes. Besides cooking meats to tenderness, include moisteners like broths, gravies or brazing liquids to further make them easier to chew.
Dairy foods are an important source of nutrition: eat milk-based products like yogurt or cheese as much as you can handle. If you have problems with these or also nut butters, then consider meal replacement beverages like instant breakfast or whey protein beverages.
And don't forget whole grains. Although some can be hard to chew, you can prepare them in hot cereal form (like oatmeal) to tenderize them. You can also prepare thin bread toast and cut into smaller pieces.
Hopefully, your treatment will bring your TMD symptoms under manageable control. Until then (and after, if need be) adjust your diet to eat the foods that keep you healthy.
If you're suffering from jaw pain or impaired function, it may not be the only source of chronic pain in your body. Of the millions of adults with temporomandibular joint disorders (TMD), many have also been diagnosed — among other conditions — with fibromyalgia, rheumatoid arthritis or sleep problems.
TMD is actually a group of painful disorders that affect the jaw joints, muscles and surrounding tissues. Besides pain, other symptoms include popping, clicking or grating sounds during jaw movement and a restricted range of motion for the lower jaw. Although we can't yet pinpoint a definite cause, TMD is closely associated with stress, grinding and clenching habits or injury.
It's not yet clear about the possible connections between TMD and other systemic conditions. But roughly two-thirds of those diagnosed with TMD also report three or more related health conditions. Debilitating pain and joint impairment seem to be the common thread among them all. The similarities warrant further research in hopes of new treatment options for each of them.
As for TMD, current treatment options break down into two basic categories: a traditional, conservative approach and a more interventional one. Of the first category, at least 90% of individuals find relief from treatments like thermal therapy (like alternating hot and cold compresses to the jaw), physical therapy, medication or mouth guards to reduce teeth clenching.
The alternative approach, surgery, seeks to correct problems with the jaw joints and supporting muscles. The results, however, have been mixed: in one recent survey a little more than a third of TMD patients who underwent surgery saw any improvement; what's more alarming, just under half believed their condition worsened after surgery.
With that in mind, most dentists recommend the first approach initially for TMD. Only if those therapies don't provide satisfactory relief or the case is extreme, would we then consider surgery. It's also advisable for you to seek a second opinion if you're presented with a surgical option.
Hopefully, further research into the connections between TMD and other inflammatory diseases may yield future therapies. The results could help you enjoy a more pain-free life as well as a healthy mouth.

Periodontal (gum) disease is a serious matter. Not only can it wreak havoc with your gums, it could also cause bone loss in the jaw that supports your teeth.
Gum disease is a bacterial infection that originates from a thin film of food particles on tooth surfaces called plaque. If you're not diligent about removing plaque through daily brushing and flossing, it can become a feeding ground for certain strains of bacteria that trigger gum infections. Left untreated, the disease can advance deeply into the teeth's supporting structures.
We're particularly concerned about furcations, the specific locations where multiple roots of a tooth fork or separate. When these locations become infected we call it a furcation involvement or invasion. The bone along the furcation will begin to deteriorate and dissolve, following a progression of stages (or classes) we can measure by probing the gum tissue or through x-ray evaluation:
- Class I: the furcation feels like a groove, but without any noticeable bone loss;
- Class II: a depression of about two or more millimeters develops indicating definite bone loss;
- Class III: Â bone loss now extends from one side of the root to the other, also known as “through and through.”
Treating furcation involvements can prove challenging because the infection is usually well below the gum line (sub-gingival). As with all gum disease treatment, our primary approach is to remove all plaque and calculus (hardened plaque deposits) where we find it, including around the roots. We typically use specially shaped instruments to clean the root surfaces. We can also employ an ultrasonic device that loosens plaque and calculus with high-frequency vibrations and flushed away with water.
Sometimes, we may need to surgically access involved furcations to clean them and stimulate bone growth with grafting. We can also use surgery to make the areas easier to clean — both for you and for us during your regular office cleanings — to prevent reoccurrences of infection.
Of course, preventing gum disease in the first place is your best defense against oral problems like furcation bone loss. Be sure you brush and floss every day, and visit us for thorough cleanings at least twice a year (unless we recommend more). This will help make sure not only your gums, but the bone that supports your teeth stays healthy.
