Nearly 40,000 people are diagnosed with oral cancer annually in the United States, with more than 8,000 dying every year from the disease. Oral cancer has a higher death rate than many other common cancers, including cervical cancer, testicular cancer, Hodgkin’s lymphoma, and thyroid or skin cancers. The high death rate results from the fact that most oral cancers go undiagnosed until the disease is well advanced and has spread to another part of the body, most often, the lymph nodes in the neck.

Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani and our team want you to know that cancers of the mouth and throat, which account for about three percent of all cancers in the United States, are largely preventable. However, we want you to know about certain risk factors that affect the likelihood of developing the disease.

• Use of tobacco products including smoking cigarettes, cigars or a pipe, or chewing tobacco all elevate risk for developing oral cancer. Tobacco use especially, is a serious risk factor because it contains substances called carcinogens, which harm cells in your mouth.
• Consumption of alcohol in excess can also increase your risk. If you drink alcohol regularly, you have an elevated risk of getting oral cancer. Alcohol abuse (more than 21 drinks in one week) is the second largest risk factor for the development of oral cancer, according to the Oral Cancer Foundation.
• Excessive sun exposure. People who spend lots of time outdoors and do not use proper amounts of sunscreen or lip balm have a greater risk for developing lip cancer. Exposure to ultraviolet (UV) radiation from sunlight may also cause melanoma, the most serious type of skin cancer.

If you notice unusual lumps, bumps, or red or white patches in your mouth that don’t go away, sores that won’t seem to heal, persistent soreness, or pain or difficulty swallowing please consult Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani and our team immediately.

Other factors that may influence your risk for developing oral cancer include:

• Age: Oral cancer is typically a disease that affects older people, usually because of their longer exposure to other risk factors. Most patients diagnosed with oral cancer are over the age of 40.
• Gender: Oral cancer strikes men twice as often as it does women.
• A history with viral infections, such as human papillomavirus (HPV)
• A diet low in fruits and vegetables

During your next visit, Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani will examine your mouth for signs of oral cancer. If you have been putting off a visit to our Dallas office for your regular checkup, now is an excellent time to schedule one. Regular visits can be the first line of defense against oral cancer because we can identify early warning signs of the disease. Give us a call today!

You’re busy getting ready for your day, and of course you’re starting your day off right by looking after your dental health. A two-minute brushing, some careful flossing, and—wait, is that a white spot on your tooth?

If your mirror reveals a patch of white on your enamel, it could be a symptom of early tooth decay.  Does this mean a cavity is necessarily in your future? Perhaps not, if you act promptly to reverse the damage!

Cavities, after all, don’t suddenly appear in our mouths. Tooth decay is a process, and it begins with a weak area in the enamel that often appears as a white spot on the tooth. These weak spots are known as “incipient cavities,” because they can easily become cavities if left untreated.

Why do these weak spots occur? And how can we repair them? Let’s look at some tooth science.

• Demineralization

Your tooth enamel is one of the marvels of the human body. Enamel is mostly made of calcium and phosphate ions, minerals which combine to form hydroxyapatite crystals. These crystals create a substance so strong that tooth enamel is the hardest part of the body—harder even than bones.

But it’s not indestructible! If you don’t care for your teeth with regular brushing and flossing, you’re leaving your enamel open to attack.

The bacteria in plaque convert the nutrients they get from the food we eat—especially sugars—into acids. These acids strip away the calcium and phosphate minerals which are the building blocks of our enamel, weakening the surface of the tooth.

Over time, these weak spots get bigger and deeper as bacteria and acids continue to attack the tooth surface. Eventually, cavities form, damaging the enamel surface, and, over time, even reaching into the dentin and the pulp inside the tooth. Once a cavity has formed, you need dental treatment to clean away the decay and repair the tooth structure.

The good news is that, when caught early, it’s possible to rebuild a weak spot in the tooth enamel before a cavity can fully develop.

• Remineralization

While acids strip minerals from your enamel, your body is also replacing those lost minerals all throughout the day. How does this balancing act take place? With the help of saliva.

The very minerals which acids strip from your enamel are found in saliva. Saliva bathes your teeth with calcium and phosphate ions which, in turn, bond with your enamel to rebuild and restore enamel strength. When missing minerals are replaced like this, it’s called remineralization.

But this careful balance of demineralization/remineralization can become upset. If you neglect brushing and flossing, for example, plaque buildup will increase the amount of acids your teeth are exposed to. This means that your body won’t be able to replace the minerals as quickly as they are stripped away, and the result is a white patch on your tooth where the enamel has lost mineral strength.

If you’re surprised by the appearance of a white spot on your tooth, it’s a good idea to visit our Dallas office for a diagnosis. If the spot is caused by an incipient cavity, Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani can provide you with some options to restore your enamel’s strength.

Fluoride toothpastes and fluoride treatments are some of the most efficient ways to remineralize your teeth. Fluoride is attracted to the minerals in your enamel. It bonds with the tooth surface, and, once there, it helps attract the calcium and phosphate ions in your saliva to restore lost minerals and repair weak spots.

But fluoride does more than just restore your tooth’s strength—it improves it! Fluoride ions join with the calcium and phosphate minerals in your teeth to form fluorapatite crystals, which are even larger and stronger than hydroxyapatite crystals.

Early treatment is your best opportunity to reverse the early stages of tooth decay. Keeping up with your brushing and flossing, eating a dental-healthy diet, seeing Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani regularly, and treating incipient cavities promptly will help ensure there are no unwelcome surprises in the mirror—just beautiful, healthy smiles!

The best type of whitening for your smile depends on what you are hoping to accomplish.

Whitening Toothpastes

This is certainly the easiest method of whitening, but will brushing alone produce your whitest smile? Probably not. Whitening toothpastes use chemicals and abrasives to remove some surface stains caused by foods, beverages and smoking. They can also be used to maintain the appearance of your teeth after a professional whitening. However, toothpaste alone cannot change the natural color of your teeth or penetrate the surface of the tooth to remove deeper stains. A whitening toothpaste usually takes several weeks to produce results. Be sure to choose a product with a seal of approval from a reputable dental association and carefully follow the instructions for use.

Whitening Strips and Gel Trays

Whitening gels can be applied at home with strips or tray kits. These peroxide-based gels are stronger than the formulas used in toothpaste.

Strips come coated with the whitening gel and work when pressed to your teeth for a specified amount of time. One difficulty here is making sure each tooth is completely covered by the strip so that even whitening takes place. Tray and gel whitening systems provide a mouthguard-like appliance that is filled with whitening gel and applied to your teeth, again for a specific period of time. Because one size does not fit all, stock trays can be ill fitting and lead to problems with gums and soft tissue. You can talk to our team about a custom-fitted appliance and whether gel whitening is your best option.

Some users find gel products cause tooth and gum sensitivity and even enamel damage. These over-the-counter gel products will not work on caps, veneers, crowns, or bridges, and there might be underlying conditions in your natural teeth that will make the use of these products ineffective. Please talk to us at your next visit to our Dallas office if you are interested in whitening at home, so we can advise you on how to achieve the best and safest outcome.

Office Treatment

Professional whitening makes use of a gel with a higher concentration of peroxide and should only be provided by Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani or a member of our team at our Dallas office. This process is generally faster, more effective and longer lasting. We take care first to examine your teeth for pre-existing conditions such as cavities and gum disease that could cause problems. We protect your gums when the gel is applied in office and monitor the procedure. We can assess the progress of the whitening and suggest further treatment if needed. Custom mouthpieces can also be an option if you would like to use a whitening gel at home. A personally molded tray will fit your teeth perfectly and allow a more precise application of the peroxide gel.

Some teeth are not good candidates for normal whitening procedures at home or in office. If you have dark stains caused by trauma, drugs such as tetracycline, discoloration due to root canals, or darker dental bonding, crowns, or other prosthetics, please talk to us about other possible solutions. We want to help you achieve your brightest possible smile.

Sometimes food that’s good for your body isn’t necessarily the best for your teeth. Drs. Sheena Allen, Mark Margolin, and Moein Sadrkhani and our team want you to know which healthy foods can harm your teeth and gums, and what steps you can take to continue enjoying these foods, even when you’re dieting.

When you begin to substitute empty calories with whole foods, make sure you also remember to focus on your dental health. The majority of people tend to switch out sugary foods in favor of fruits and vegetables when they diet.

It’s worth knowing that most fruits are highly acidic and composed of natural sugars. Some of the highly acidic fruits to watch out for include apples, grapes, strawberries, pineapples, blueberries, oranges, and grapefruit. Moderation is key here, as with all other things. Fruits can be a great source of energy to help you through your day, but try not to overdo them.

Often, people also incorporate more leafy greens into their diets, which mean plenty of salads. Salad dressing is another item you’ll want to watch out for. Many dressings are filled with vinegars and sweeteners that include harmful acids, which change the pH of your mouth. When your mouth shifts from alkaline to acidic, your smile also turns to a higher risk for erosion and decay.

Rather than get rid of these foods altogether, simply change what you do after you eat them. Rinse your mouth out with water, brush your teeth, or eat alkalizing foods after consuming these acidic foods. Healthy alkalizing foods include dairy products such as eggs and yogurt, or any type of vegetable.

If you have questions regarding your current diet and its effect on your oral health, please contact our Dallas office and speak with a member of our staff. If you’ve begun to make changes in your diet toward a healthier lifestyle, we hope these tips can help your make positive changes to your oral health. Our team at Dallas Dental Arts wants a healthy lifestyle to be a top priority in your life.
