Although we've known for some time how tooth decay forms, it's still prevalent across the population—even more so than cancer or heart disease. Along with gum disease, it's a leading cause of tooth loss.
Fortunately, our knowledge about tooth decay has grown considerably, to the point that we now recognize a number of risk factors that make it more likely a person will develop this disease. By first identifying them in individual patients, we can take steps to address them specifically to reduce the chances of this destructive disease.
Genetics. Researchers have identified around 40 to 50 genes that can influence cavity development. The best way to assess your genetic risk is through family history—if numerous close family members contend with tooth decay, your risk may be high. If so, it's important to be extra vigilant with addressing other areas over which you have more control.
Saliva. Cavities are directly caused by oral acid, a byproduct of bacteria, that can erode tooth enamel over prolonged contact. This is minimized, though, through a normal saliva flow that neutralizes acid and helps remineralize enamel. But poor saliva production can slow acid neutralization. You can improve your saliva flow by drinking more water, changing medications or using saliva-boosting products.
Oral hygiene. You can reduce bacteria (and thus acid) by removing their "room and board"—dental plaque. This accumulating film of food particles harbors the bacteria that feed on it. Daily brushing and flossing, accompanied by regular dental cleanings, effectively removes dental plaque, which in turn lowers the levels of oral bacteria and acid.
Dental-friendly diet. Even if you diligently address the previous risk factors, your diet may fight against your efforts. Diets high in processed and refined foods, especially sugar, provide abundant food sources for bacteria. On the other hand, a diet primarily of whole foods rich in vitamins (especially D) and minerals like calcium and phosphorous strengthen teeth against decay.
Preventing tooth decay isn't a "one-size-fits-all" approach. By identifying your own particular risk, we can craft a care strategy that can be your best defense against this destructive dental disease.
It's normal to have occasional mouth dryness—that "cotton mouth" feeling when you first wake up or after eating a spicy meal. It soon dissipates, though, leaving you no worse for wear other than the memory of an unpleasant sensation.
For some, though, the unpleasant sensation becomes a chronic condition known as xerostomia, in which their mouth feels dry most of the time. And, it can have far-reaching consequences beyond a mere irritation if not treated.
Among the numerous causes for xerostomia, the most common appears to be over-the-counter and prescription medication. An estimated five hundred medications have dry mouth as a potential side-effect, from antihistamines to antidepressants. And because people over 65 are more likely to take medications, they also have a high occurrence of xerostomia.
A person with certain systemic diseases like Parkinson's Disease or undergoing radiation or chemotherapy for cancers of the head and neck may also encounter dry mouth. For example, an autoimmune disease called Sjögren's syndrome, primarily affecting postmenopausal women, can dry out the mouth's mucous membranes.
Chronic dry mouth isn't normal, and often a sign of a health problem that should be examined. And it can lead to more problems with your oral health. Because dry mouth is most likely a reduction in saliva, which helps buffer decay-causing acid and provides antibodies to fight bacteria, having less of this vital fluid can increase your risk for both tooth decay and gum disease.
So, what can you do if you're plagued by persistent dry mouth? If you suspect your medications may be a factor, talk with your doctor about whether one of them may be the underlying cause for your symptoms. You may be able to switch to an alternate medication without dry mouth side-effects.
You can also increase your water intake during the day, including drinking more before and after taking medication. And there are a number of products like the artificial sweetener xylitol found in gums and candies that can boost saliva. Your dentist may also be able to recommend products that increase saliva.
Above all, be sure you keep up daily brushing and flossing, as well as regular dental cleanings. Taking care of chronic dry mouth could help you avoid dental problems later.

While your dentist plays an important role in keeping things inside your mouth healthy, what you do every day often makes the biggest difference. Here are 5 routine things you can do for better oral health.
Brush and floss every day. The most important thing you can do for your teeth and gums is adhere to a daily schedule of brushing and flossing. These twin tasks remove the daily buildup of plaque, a thin bacterial biofilm most responsible for tooth decay and gum disease.
Check your hygiene. There's brushing and flossing—and then there's brushing and flossing effectively. To make sure you're getting the job done, run the tip of your tongue along your teeth after you brush and floss. If it feels smooth, mission accomplished! If it feels rough and gritty, though, try again. You can also use plaque disclosure products occasionally to highlight any missed plaque still on your teeth.
Say no to sugar. Chances are you love sugar—and so do the disease-causing bacteria in your mouth. As they feed on sugar, they multiply and produce acid, which in high levels can erode tooth enamel and lead to tooth decay. Limiting sugar in your diet reduces oral bacteria and the acid they produce, and thus lowers your risk for disease.
Drink plenty of water. Saliva plays an important role in oral health: It helps fight off bacteria, neutralizes acid and re-mineralizes tooth enamel. But it can't do those things if there's not enough of it. So, if your mouth consistently feels dry, drink more water to give your body what it needs to make saliva. Drinking water also washes away food particles that could become plaque and lowers your mouth's acidity.
Maintain your dental appliances. You can extend the life of dentures, retainers or other types of dental appliances by cleaning and maintaining them. You should clean your appliance regularly using regular hand soap or a designated cleaner (not toothpaste, which can be too abrasive). Unless otherwise directed by your dentist, take them out at night and be sure to store them where kids or pets can't get to them.
