Watching your kids dress up in cute, spooky costumes and go out trick-or-treating can be a real thrill. But thinking about the dental damage caused by eating all those sweets might just give you the chills. So is it best to act like a witch and take away all the candy from those adorable little ghosts and goblins?
Relax! According to experts like the American Dental Association, it’s OK to let kids enjoy some sweet treats on special occasions like Halloween—especially if they have been taking good care of their oral hygiene all year long, by brushing twice each day and flossing once every day. But to help keep cavities away from those young smiles, there are some things parents (and everyone else) should understand.
Cavities—small holes in the tooth’s outer surface that result from the decay process—get started when bacteria in the mouth feed on sugar and produce acids. The acids eat away at the hard enamel coating of teeth. If left untreated, decay will eventually reach the soft inner core of the tooth, causing even more serious damage.
There are several ways to stop the process of tooth decay. One is to take away the sugar that decay bacteria feed on. Because this ingredient is common in so many foods, it’s hard to completely eliminate sugar from the diet. Instead, it may be more practical to limit the consumption of sweets. For example, if kids are only allowed to eat sugary treats around mealtimes, it gives the mouth plenty of “downtime,” in which healthful saliva can neutralize the bacterial acids. It also helps to avoid sweets that stick to teeth (like taffy or gummy bears) and those that stay in the mouth for a long time (like hard candy).
Another way to help stop tooth decay is by maintaining top-notch oral hygiene. Decay bacteria thrive in the sticky film called plaque that clings stubbornly to the surfaces of teeth. Plaque can be removed by—you guessed it—effective brushing and flossing techniques. While it’s a good start, brushing alone won’t remove plaque from the spaces between teeth and under the gums: That’s why flossing is an essential part of the daily oral hygiene routine. Helping your kids develop good oral hygiene habits is among the best things you can do to fight cavities.
And speaking of habits, there are a few others that can help—or hurt—your oral health. For example, drinking plenty of water keeps the body hydrated and benefits oral health; but regularly drinking soda and other sweetened or acidic beverages greatly increases the risk of tooth decay. And seeing your dentist on a regular basis for professional cleanings and routine checkups is one of the most beneficial habits of all. Working together, we can help keep tooth decay from turning into a scary situation for kids—and adults too.

Placing a dental implant within the jawbone requires a surgical procedure. For most people it’s a relatively minor affair, but for some with certain health conditions it might be otherwise. Because of their condition they might have an increased risk for a bacterial infection afterward that could interfere with the implant’s integration with the bone and lead to possible failure.
To lower this risk, dentists for many years have routinely prescribed an antibiotic for patients considered at high-risk for infection to take before their implant surgery. But there’s been a lively debate among health practitioners about the true necessity for this practice and whether it’s worth the possible side effects that can accompany taking antibiotics.
While the practice still continues, current guidelines now recommend it for fewer health conditions. The American Dental Association (ADA) together with the American Heart Association (AHA) now recommend antibiotics only for surgical patients who have prosthetic heart valves, a history of infective endocarditis, a heart transplant or certain congenital heart conditions.
But patients with prosthetic joint replacements, who were once included in the recommendation for pre-surgical antibiotics, are no longer in that category. Even so, some orthopedic surgeons continue to recommend it for their joint replacement patients out of concern that a post-surgical infection could adversely affect their replaced joints.
But while these areas of disagreement about pre-surgical antibiotics still continue, a consensus may be emerging about a possible “sweet spot” in administering the therapy. Evidence from recent studies indicates just a small dose of antibiotics administered an hour before surgery may be sufficient to reduce the risk of infection-related implant failure with only minimal risk of side effects from the drug.
Because pre-surgical antibiotic therapy can be a complicated matter, it’s best that you discuss with both the physician caring for your health condition and your dentist about whether you should undergo this option to reduce the infection risk with your own implant surgery. Still, if all the factors surrounding your health indicate it, this antibiotic therapy might help you avoid losing an implant to infection.

Radiographic (x-ray) images are an indispensible diagnostic tool in dentistry. One of the most routine and useful types of x-rays dentists take is the so-called bitewing. Here are some things you may want to know about this common diagnostic procedure.
What are bitewing x-rays?
Bitewings reveal the presence and extent of decay in the back teeth, specifically in areas where adjacent teeth touch each other. Unlike other areas of the teeth, these contacting surfaces between adjacent teeth can’t be examined visually. Bitewings can also show areas of bone loss around teeth — a sign of periodontal disease; however, they are not taken for that purpose because bitewings will not show the complete root surface that is surrounded by bone.
Why are they called that?
The name “bitewing” refers to how the film — or sensor, in the case of a digital x-ray — is positioned in the mouth: The patient bites down on a little tab or wing that holds the apparatus in place.
How often do I need them?
This is determined on a case-by-case basis, with the goal of not exposing you to any more radiation than necessary — even the minimal amount found in a series of bitewing x-rays. Your individual susceptibility to caries (tooth decay) and personal dental history will play a major role in determining how frequently you need radiographic examination — and, for that matter, how often you need to come in for routine cleanings and exams.
Are they safe?
The safety of bitewing x-rays is best illustrated with a comparison to the regular daily radiation exposure we get every day from environmental sources, which is about 0.01 millisieverts — the unit of measure we use for radiation. A series of 4 bitewing x-rays exposes you to 0.004 millisieverts of radiation — less than half of the daily exposure. Undetected tooth decay, which can spread quickly through the softer inner layers of teeth, is considered much more dangerous!
If a bitewing x-ray shows that there is tooth decay, what happens next?
If the cavity is very small, we may be able to treat it during the same appointment. If not, we will make a separate appointment to make sure it is taken care of promptly. The sooner tooth decay is treated, the better!
