Oral cancer is one of the more dangerous malignancies people face. But there are ways you can reduce your risk of this deadly disease through changes in lifestyle habits and behaviors.
Two of the better known behaviors for increased oral cancer risk are immoderate consumption of alcohol and the use of tobacco, particularly chewing tobacco and snuff. Eliminating these, especially the latter, can vastly improve your odds of avoiding cancer. Another factor is a strain of the human papilloma virus (HPV 16) that's transmitted sexually, which you can avoid through safe sex practices.
In addition to these lifestyle changes, there's one more you should make to lower your oral cancer risk: adjustments to your diet. Research over the last half century has provided ample evidence of a link between the foods we eat and our risk of all types of cancers, including oral.
The biggest concern is over certain elements in some foods that can damage DNA, the molecular “operating instructions” that regulate the formation and function of our bodies' cells. These elements are collectively known as carcinogens because of their role in cancer formation.
An example of a carcinogen is a group of chemicals called nitrosamines. These form during preservation processes using nitrites in meats like bacon or ham. They're also found in beer or certain preserved fish. To limit your consumption of nitrosamines, you should reduce these and other processed products and replace them with fresh fruits and vegetables, or organic meats and dairy products.
Our DNA can also be damaged by unstable molecules called free radicals that arise during normal cellular function. But there are also substances known as antioxidants that help protect the cells from free radical damage. Many plant-based foods contain nutrients like vitamins C and E that have antioxidant properties, so including them in your diet could help reduce your oral cancer risk.
Several clinical studies over the years have been consistent in their findings that a diet rich in fresh fruits and vegetables can reduce the risk of oral or throat cancers, as well as other forms of cancer. Making changes to your diet in that direction, plus other lifestyle changes, could help you avoid this devastating oral disease.

Tooth enamel, to play on a phrase from Shakespeare, is made of “sterner stuff.” The strongest substance in the body, enamel can take years of biting and chewing and keep on going.
It does have one nemesis, though—mouth acid, which can soften and erode enamel’s mineral content. This is less of a concern if you have healthy saliva flow, because saliva neutralizes acid in thirty minutes to an hour after an acid attack and can also help re-mineralize the enamel. Daily brushing and flossing also help curb mouth acid by reducing the bacteria that produces it.
But as effective as saliva is at neutralizing mouth acidity, it can be overwhelmed by outside acid derived through certain foods and beverages. In the past couple of decades, at least two of these acid sources have grown in prominence: energy drinks and, believe it or not, sports drinks.
Just how acidic are they? The pH scale runs from 1 to 14, with acidity on the low end and alkalinity on the higher (7 is neutral). Tooth enamel begins dissolving below 5.5. Laboratory tests have pegged the average pH of energy drinks at 3.05 and sports drinks, 2.91.
Because of their acidity, frequent energy or sports drink consumption will bring mouth pH into the danger zone for tooth enamel. It’s even more likely if these beverages are sipped over an extended period, which can prevent saliva from getting ahead of any newly introduced acid.
Keeping your distance from these beverages is probably the safest bet. But if you do imbibe occasionally, follow these common sense tips:
- Avoid sipping the beverage over long periods—and try to limit drinking them to meal times;
- After drinking a beverage, wash your mouth out with water and wait an hour to brush to give your saliva time to neutralize any acid.
- Practice consistent, daily brushing and flossing.
Above all, keep a healthy respect for acidic foods and beverages like energy and sports drinks and don’t overuse them. Your tooth enamel will appreciate it.

Tooth decay doesn't appear out of nowhere. It begins with bacteria, which produce acid that softens and erodes tooth enamel. Without adequate enamel protection, cavities can develop.
So, one of our prevention goals is to decrease populations of disease-causing bacteria. One way is to deprive them of carbohydrates, a prime food source, most notably refined sugar. That's why for decades dentists have instructed patients to limit their intake of sugar, especially between meal snacks.
Ironically, we're now consuming more rather than less sugar from a generation ago. The higher consumption impacts more than dental health — it's believed to be a contributing factor in many health problems, especially in children. Thirty years ago it was nearly impossible to find a child in the U.S. with type 2 diabetes: today, there are over 50,000 documented juvenile cases.
Cutting back isn't easy. For one thing, we're hard-wired for sweet-tasting foods. Our ancestors trusted such foods when there was limited food safety knowledge. Most of us today still have our "sweet tooth."
There's also another factor: the processed food industry. When food researchers concluded fats were a health hazard the government changed dietary guidelines. Food processors faced a problem because they used fats as a flavor enhancer. To restore flavor they began adding small amounts of sugar to foods like lunch meat, bread, tomato sauce and peanut butter. Today, three-quarters of the 600,000 available processed food items contain some form of added sugar.
Although difficult given your available supermarket choices, limiting your sugar intake to the recommended 6 teaspoons a day will reduce your risk for dental and some general diseases. There are things you can do: replace processed foods with more fresh fruits and vegetables; read food labels for sugar content to make better purchasing decisions; drink water for hydration rather than soda (which can contain two-thirds of your daily recommended sugar allowance), sports drinks or juices; and exercise regularly.
Keeping your sugar consumption under control will help you reduce the risk of tooth decay. You'll be helping your overall health too.

We don’t often think about it, but eating is a multi-staged process. It starts, of course, with food that’s hopefully high in nutritional value. But you also need coordinated jaw action to chew and shred your food that when combined with the enzymes in saliva can then be effectively digested in the stomach.
But what if you’re unable to chew some foods because you suffer from chronic jaw pain and dysfunction? This is the situation for millions of people who suffer from problems associated with the jaw joints—temporomandibular joint disorders (TMD). It’s not just the chronic pain and discomfort TMD can cause that’s a real issue—it may also be preventing you from eating foods that are healthy for you.
Because TMD can make it difficult to open your jaws wide or causes pain when you bite down, you might especially have trouble with certain fruits and vegetables as well as many meats. Many people opt to skip otherwise healthy foods because they’re too difficult to eat. That, however, could lead to lack of proper nutrition in the long run.
But with a few techniques and modifications, you can still include many of these foods in your diet even when TMD discomfort flares up. For one, be sure to cut all your food portions (including toast) into small, bite-sized pieces. These should be small enough to limit the amount of jaw opening required to comfortably place the bite in your mouth and chew. When preparing your food, be sure to peel fruits and vegetables that have skin, which is often hard to chew.
You should also try cooking crisper fruits and vegetables to a soft, moist texture. Choose meat cuts, poultry or seafood that can be cooked to a tender, moist consistency—you can also use gravies and sauces to further moisten them.
And don’t forget to chew slowly. Not only does slower eating aid in digestion, it will help you avoid overworking your jaw joints.
With a few adjustments you can have a normal, nutritious diet and minimize the discomfort of your TMD symptoms. Continual healthy eating is a must for overall health and quality of life.

Your teeth’s hard, enamel coating protects them from environmental dangers or disease. But although it’s made of the hardest substance in the human body, enamel isn’t invincible — prolonged exposure to acid can cause dental erosion, a condition in which the enamel’s mineral content permanently dissolves, a process known as de-mineralization.
De-mineralization occurs anytime our mouth environment becomes too acidic due to eating or drinking items with high acid content. Saliva normally neutralizes mouth acid in thirty minutes to an hour after we eat, as well as restores mineral content to the enamel (re-mineralization). Danger arises, though, if the saliva’s buffering action is overwhelmed by chronic acidity, caused mainly by constant snacking or sipping on acidic foods and beverages throughout the day — in this situation, saliva can’t complete the process of buffering and re-mineralization.
As a result, the enamel may permanently lose its mineral content and strength over time. This permanent dental erosion leads to serious consequences: the teeth become more susceptible to decay; the dentin becomes exposed, which causes pain and sensitivity to pressure and temperature changes; and changes in the teeth’s size and color can negatively alter your appearance.
It’s important to take action then before dental erosion occurs. Along with daily oral hygiene, restrict your consumption of acidic foods and beverages to meal times and cut back on between-meal snacks. Rather than a sports drink after exercising, drink nature’s hydrator — water. You should also alter your brushing habits slightly — rather than brush right after you eat, wait thirty minutes to an hour. This gives saliva time to restore the mouth to its normal pH and re-mineralize the enamel. Brushing right after can remove even more of the minerals in softened enamel.
If significant erosion has occurred, there are a number of treatment options we can undertake to preserve remaining tooth structure and enhance your appearance. In moderate cases, we can reshape and cover damaged teeth using dental materials like composite resins or porcelain to fill decayed areas or cover teeth with veneers or crowns.
The key of course, is to identify dental erosion through clinical examination as soon as possible to minimize damage. Your enamel plays a critical role in protecting your teeth from disease — so take the right steps to protect your enamel.
