You probably know practicing healthy dietary and lifestyle habits can help prevent tooth decay and periodontal (gum) disease. But good habits could also lower your risk for a more dangerous type of disease — oral cancer.
There are several risk factors for oral cancer, including those you can't do much about like your genetic makeup or unknown elements in the environment. But there are factors you can influence with your actions.
You're probably familiar with the links between tobacco use (both smoked and smokeless) and oral cancer. But excessive alcohol use could also increase your risk, as can risky sexual behavior that could expose you to human papilloma virus (HPV) 16.
And what you eat — or don't eat — could also influence your cancer risk. Research over the last half century has uncovered a link between diet and cancer. Cancer development seems to begin with damage to DNA, the genetic material that “tells” each of our cells what it is and what it does in the body. Substances called carcinogens found in the environment — including the foods we eat — can damage our DNA and open the door for cancer to development.
But some foods also contain elements that protect our DNA from carcinogenic damage. Some of these are known as antioxidants, which protect cells from unstable molecules called free radicals. You'll find antioxidants, as well as other protective substances like fiber, vitamins and lycopene in plant-based foods, particularly fruits and vegetables.
Eating a plant-based diet also means you'll eat fewer foods that contribute to the rise of free radicals like saturated fat, animal protein and nitrates (a chemical that occurs in some food processing). A healthy diet, along with quitting tobacco use and moderating alcohol consumption, will help not only preventing decay or gum disease, it will also drastically lower your risk for oral cancer.

For years preparing teeth for fillings or other restorations has required the use of a drill. Although quite effective in removing decayed structure and preparing the tooth for bonding, it usually requires a local anesthetic. That and the noise it generates can be unsettling for many patients.
In recent years, a different type of technique known as “air abrasion” has increased in popularity among dentists. Known also as “particle abrasion,” the technique uses a stream of fine particles to remove decayed tooth structure and is less invasive than the traditional drill. Although the technology has been around since the mid-20th Century, recent developments in suction pumps that remove much of the dust created have made it more practical. It also works well with new natural-looking bonding materials used for tooth structure replacement.
The fine particles — usually an abrasive substance like aluminum oxide — are rapidly discharged through a hand-held instrument using pressurized air aimed at affected tooth areas. Decayed teeth structure is softer than healthier tissue, which allows air abrasion to precisely remove decay while not damaging the other.
Besides removing decay or abrading the tooth for bonding, air abrasion can also be used to minimize stained areas on surface enamel and to clean blood, saliva or temporary cements from tooth surfaces during dental procedures. It’s also useful for smoothing out small defects in enamel or aiding in sealant applications.
It does, however, have a few limitations. It’s not as efficient as the traditional drill with larger cavities or for re-treating sites with metal (amalgam) fillings. Because of the fine texture of the abrasive particles, affected teeth need to be isolated within the mouth using a rubber dam or a silicone sheet. High-volume suction must be continually applied to capture the fine particles before the patient swallows them or it fills the procedure room with a fine cloud of material.
Still, while air abrasion technology is relatively new, it has clear advantages over the traditional drill in many procedures. As advances in the technology continue, air abrasion promises to offer a more comfortable and less invasive experience in dental treatment.
Making sure children are comfortable when visiting the dentist is an essential part of creating a lifetime habit of dental care. We recommend children start dental visits around their first birthday.
But for some children this may not be enough — despite parents’ and dentists’ best efforts they may still develop an inordinate fear of dental visits and even routine procedures. This kind of anxiety could inhibit them now and later in life from receiving needed dental care.
To relieve this anxiety, dentists have developed sedation therapy for children. Not to be confused with anesthesia, which numbs pain, sedation uses drugs to place a patient in a relaxed state. Depending on the drugs and dosage used, we’re able to achieve anywhere from a light state of relaxation to a deep suppression of consciousness. The approach is similar to one used with adults, although drug dosages and applications will differ with children.
Â If we’re planning to use sedation with your child we recommend you feed them a low-fat dinner the night before and then refrain from any other foods or liquids until after treatment the next day.Â Just before the procedure (and after we’ve evaluated them physically to be sure they’re healthy enough for the sedation medication), we’ll administer the sedative, usually Midazolam and Hydroxyzine. Taken by mouth in a syrup form, this places them in a mildly relaxed state.
During the procedure a designated staff member will continually monitor their pulse, breathing, blood pressure and other vital signs. We may also take other protective measures like special chair positioning or immobilization to keep movement to a minimum.
After the procedure, your child will remain in the office until their vital signs return to pre-sedation levels. Once at home, you should keep an eye on them for the rest of the day. They should not return to school or regular activities until the next day.
As sedation medication and techniques continue to advance, they’re becoming a routine part of dental care. If your child experiences anxiety, this can help make dental visits more pleasant and more likely to become part of their life from now on.
