X-rays are an important diagnostic tool in dentistry because of their ability to penetrate and pass through body tissues. Because they penetrate at different speeds depending on tissue density (shorter and thus darker on exposed film for soft tissues, longer and lighter for hard tissues like bone or teeth), we’re able to detect decay which appear as dark areas on x-ray film.
Without x-rays, the early detection and diagnosis of dental problems would be quite difficult. But despite its obvious benefits, it’s still a form of released energy that exposes patients to a certain amount of radiation. Since the potential health risk from radiation depends on the amount released (the dosage) and for how long and often a person is exposed, we must determine if the dosage and frequency from dental x-rays is a cause for concern.
It’s a common misconception to view any radiation exposure as dangerous. The truth is, however, we’re all exposed daily to radiation from the natural environment — about 2 to 4.5 millisieverts (the dosage measurement for radiation exposure) a year, or about 10 microsieverts (one-thousandth of a millisievert) every day.
In comparison, radiation exposure from routine dental x-rays is a fraction of this if measured over time. A set of four bitewing images of the back teeth produces 4 microsieverts of radiation, less than half the average daily exposure. One of the most comprehensive x-ray sets, a full mouth series of 18-20 images using “D” speed film, results in an exposure of 85 microsieverts, equaling about a week of normal radiation exposure.
These thoroughly researched rates help demonstrate that regular dental x-rays are relatively safe. What’s more, x-ray technology has continued to advance since first used in the mid-20th Century. With innovations in film and digital processing, today’s equipment produces only 80% of the radiation exposure of earlier machines. In effect, we’ve increased our capabilities to more accurately detect and diagnose issues through x-rays, while lowering the amount of radiation exposure.
Of course, a person’s annual exposure rate may differ from others. If you have concerns for yourself or your family about x-ray radiation exposure, please feel free to discuss this with us. Our primary goal is to improve your oral health without undue risk to your health in general.

For over half a century, dentists have promoted a proven strategy for sound dental health. Not only is this strategy effective, it’s simple too: brush and floss every day, and visit your dentist at least twice a year or as soon as you see a problem.
Unfortunately, this strategy isn’t resonating well with people between the ages of 18 and 34, known more commonly as the “millennials.” A recent survey of 2,000 members of this age bracket found a startling number: over one-third didn’t brush their teeth as often as recommended, some going as long as two days between brushings. About the same number also reported fear of dental visits. Given all that, the next statistic isn’t surprising: tooth decay affects one in three people in the millennial age group.
This isn’t to pick on millennials, but to point out that good oral hygiene naturally leads to good oral health, regardless of age, gender or ethnicity. Here’s more about the dental care basics for better health.
Brush twice, floss once daily. The American Dental Association (ADA) recommends a thorough brushing with toothpaste containing fluoride twice a day. You also shouldn’t neglect a once a day flossing between teeth to remove plaque from areas brushing can’t effectively reach. Keeping plaque accumulation to a minimum is the best way to prevent diseases like tooth decay or periodontal (gum) disease.
Visit your dentist at least twice a year. Dental visits every six months (or more if your dentist recommends it) accomplish two things: a professional dental cleaning removes any buildup of plaque and tartar (calcified plaque) missed by daily hygiene. It also allows your dentist to inspect your teeth and gums for any signs of disease that may require treatment.
See your Dentist ASAP if you notice problems. You should also see your dentist sooner if you notice anything abnormal like unusual spotting on the teeth, tooth pain or sensitivity, or swollen, reddened or bleeding gums. These are all signs of disease, and the sooner it’s treated the less chance your teeth and gums will suffer serious harm.
Like other age groups, millennials know the importance of a healthy smile, not only for social and career interaction, but also for their own personal well-being. Sticking to a regular dental care program is the primary way to keep that healthy smile.
Everyone knows that in the game of football, quarterbacks are looked up to as team leaders. That's why we're so pleased to see some NFL QB's setting great examples of… wait for it… excellent oral hygiene.
First, at the 2016 season opener against the Broncos, Cam Newton of the Carolina Panthers was spotted on the bench; in his hands was a strand of dental floss. In between plays, the 2105 MVP was observed giving his hard-to-reach tooth surfaces a good cleaning with the floss.
Later, Buffalo Bills QB Tyrod Taylor was seen on the sideline of a game against the 49ers — with a bottle of mouthwash. Taylor took a swig, swished it around his mouth for a minute, and spit it out. Was he trying to make his breath fresher in the huddle when he called out plays?
Maybe… but in fact, a good mouthrinse can be much more than a short-lived breath freshener.
Cosmetic rinses can leave your breath with a minty taste or pleasant smell — but the sensation is only temporary. And while there's nothing wrong with having good-smelling breath, using a cosmetic mouthwash doesn't improve your oral hygiene — in fact, it can actually mask odors that may indicate a problem, such as tooth decay or gum disease.
Using a therapeutic mouthrinse, however, can actually enhance your oral health. Many commonly available therapeutic rinses contain anti-cariogenic (cavity-fighting) ingredients, such as fluoride; these can help prevent tooth decay and cavity formation by strengthening tooth enamel. Others contain antibacterial ingredients; these can help control the harmful oral bacteria found in plaque — the sticky film that can build up on your teeth in between cleanings. Some antibacterial mouthrinses are available over-the-counter, while others are prescription-only. When used along with brushing and flossing, they can reduce gum disease (gingivitis) and promote good oral health.
So why did Taylor rinse? His coach Rex Ryan later explained that he was cleaning out his mouth after a hard hit, which may have caused some bleeding. Ryan also noted, “He [Taylor] does have the best smelling breath in the league for any quarterback.” The coach didn't explain how he knows that — but never mind. The takeaway is that a cosmetic rinse may be OK for a quick fix — but when it comes to good oral hygiene, using a therapeutic mouthrinse as a part of your daily routine (along with flossing and brushing) can really step up your game.
