Although cancer treatment has advanced steadily in recent decades, the most used therapies continue to be radiation and chemotherapy to eradicate cancerous cells. And while they often work, both can cause "collateral damage" in healthy tissues near the targeted cells.
This can create a number of indirect consequences for a patient's health, including in the mouth. The salivary glands, for example, can be damaged by radiation treatments aimed at the head or neck. The effect on these glands can interrupt the normal flow of saliva and cause xerostomia or "dry mouth."
Lack of adequate saliva causes more than an unpleasant, sticky mouth feeling. One of saliva's main functions is to neutralize acid that builds up naturally after eating. Without it, high acid levels can cause enamel and root surface erosion and lead to tooth decay.
Cancer treatment can also contribute to gastro-esophageal reflux disease (GERD). This disease causes stomach acid to bypass the natural tissue barriers of the esophagus and enter the mouth. As with dry mouth, the increased acid level from GERD can be just as devastating to enamel—and the damage will be permanent.
To minimize these effects on your dental health, it's important to take proactive steps before, during and after cancer treatment. If at all possible, have any needed dental work performed before you begin radiation or chemotherapy—it's better to start it with teeth and gums as healthy as possible.
During treatment, try to continue regular dental visits to monitor your oral health and receive any needed preventive or therapeutic treatments. Depending on your condition and the advice of your dentist, you may need to increase your visit frequency during this time. Your dentist can help with boosting your saliva production and strengthening your tooth enamel. But you should also practice daily brushing and flossing, drink plenty of water and seek treatment for any resulting GERD symptoms.
Even with the best efforts, though, your teeth and gums may still incur damage while treating your cancer. Fortunately, there are a wide array of materials and procedures that can effectively restore them to health. So, once your treatments are completed consult with a dentist on your options for improving the health and appearance of your teeth and gums.
Chicken pox is a common viral infection that usually occurs during childhood. Although the disease symptoms only last a short time, the virus that caused it may remain, lying dormant for years within the body's nervous system. Decades later it may reappear with a vengeance in a form known as herpes zoster, what most people know as shingles.
A shingles outbreak can be quite painful and uncomfortable—and it's also not a condition to take lightly. Occurring mainly in people over fifty, it often begins with an itching or burning sensation in the skin. This is often followed by a red rash breaking out in a belt-like pattern over various parts of the body, which may later develop into crusty sores. Symptoms may vary from person to person, but people commonly experience severe pain, fever and fatigue.
Besides the general discomfort it creates, shingles can also pose major health problems for certain people. Individuals with other health issues like pregnancy, cancer or a compromised immune system may experience serious complications related to a shingles outbreak.
In its early stages, shingles is contagious, spreading through direct contact with shingles sores or lesions or through breathing in the secretions from an infected person. This characteristic of shingles could affect your dental care: because the virus could potentially pass to staff and other patients, dentists usually postpone cleanings or other dental treatments for patients with shingles, particularly if they have a facial rash.
If you're diagnosed with shingles, most physicians recommend you begin antiviral treatment as soon as possible. You should also let your dentist know if you have shingles, which may put off any scheduled treatments until your doctor determines you're no longer contagious.
There's one other thing you can do, especially if you're over 60: obtain a shingles vaccine, available from most physicians or clinics. The vaccine has proven effective in preventing the disease, and could help you avoid this most unpleasant health experience.
While it doesn’t garner the star power of blood, saliva is still an important bodily fluid. A true multi-tasker, saliva contributes in many ways to the function and health of the body, from stronger teeth to more efficient digestion.
Here are six ways saliva helps your mouth and body function properly and stay healthy.
The mouth’s natural cleanser. Bacteria are responsible for much of the dental disease that plagues us, particularly tooth decay and gum disease. Saliva clears the mouth of food remnants, bacteria’s primary feeding source, after we eat. This leaves a cleaner mouth and fewer bacteria to cause infection.
The immune system’s partner. Saliva contains an antibody called Immunoglobulin A (IgA) that attacks disease-causing microorganisms. Along with secreting other antibacterial agents like lactoferrin and lyzozyme that curb the growth and development of bacteria, saliva serves as the body’s first line of defense against pathogens entering through the mouth.
Acid neutralizer. The optimal oral environment is a neutral pH of 7. Many of our foods and beverages, though, are highly acidic, which can raise the mouth’s acid level. The acidic environment causes the minerals in tooth enamel to soften and dissolve (a process called de-mineralization). Saliva restores the balance by neutralizing any remaining acid after we eat (a process that takes about 30 to 60 minutes).
Mineral replacer. Even under normal conditions, enamel will de-mineralize to some extent whenever the mouth becomes acidic. Saliva restores some of the enamel’s lost minerals like calcium and phosphate while it’s neutralizing acid. If fluoride is also present in saliva from fluoridated drinking water or toothpaste, it too is absorbed by the enamel making it stronger and more resistant to acid attacks.
Digestion enhancer. Saliva lubricates the mouth while we eat, making it easier for us to chew (and taste) our food. Saliva also releases the enzyme amylase as we chew to break down starches before the food enters our stomach. The end result is more efficient and comfortable digestion.
The wave of the future in diagnostics. Like blood and urine, saliva contains genetic and disease markers that could tell a physician if a patient has a certain condition. Since collecting a saliva sample is much easier than with these other bodily fluids, diagnosing disease with saliva will become more prevalent as more calibrated devices reach the market.
