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!
You’ve decided to obtain dental implants for your missing teeth. It’s a good choice — they provide the closest restoration to the function and appearance of natural teeth. You will, however, need to undergo a surgical procedure to imbed the implants’ threaded titanium posts into supporting bone.
It’s understandable if you’re a little apprehensive about undergoing surgery. We’re here, though, to set your mind at ease: implantation is a relatively minor procedure carefully planned in advance. Most patients experience no discomfort during the procedure and very little afterward.
We begin by completely numbing the surgical site with a local anesthetic. If you have a high level of anxiety, we can also administer a sedative or similar medication to help you relax. We then access the underlying bone through a series of incisions that create a flap in the gum tissue that we’ll later suture closed.
It’s quite common to have prepared a surgical guide or template beforehand. The template placed in the mouth marks the exact site for a small channel (or hole) we create in the bone. We then incrementally increase the size of the hole by drilling until it matches precisely the implant’s size and shape. This takes time to avoid overheating and damaging the bone.
We then remove the implant from its sterile packaging and insert it into the opening. We’ll also take x-rays to ensure correct positioning, which is critical for achieving an attractive result. We then suture the gum flap in place using stitches that will eventually dissolve. The implant will then integrate with the bone for a few weeks to create a strong, durable hold before we continue with the restoration.
Most patients can manage any post-surgical discomfort with mild anti-inflammatory pain relievers like aspirin or ibuprofen, although we can prescribe something stronger if you need it. We may also prescribe a mouthrinse with an anti-bacterial agent like chlorhexidine for you to use while the gums are healing to reduce the risk of infection.
Implant surgery is part of a long process that will eventually result in regaining the function of your lost teeth. What’s more, undergoing this minor procedure will also help you regain something just as important — a beautiful smile.

While the effectiveness of chemotherapy and radiation have contributed to rising cancer survival rates, they can still have an adverse effect on the rest of the body. That includes the mouth: these treatments can damage healthy tissues like the salivary glands. The decrease in saliva flow increases the risk of tooth decay or periodontal (gum) disease.
While overcoming cancer is certainly the patient’s main health priority, it’s important for them to tend to their oral health. The best approach often involves a three-way partnership between patient, dentist and family caregivers all doing their part to keep the patient’s teeth, gums and mouth healthy during cancer treatment.
Here’s what each “partner” can do to protect a cancer patient’s oral health during treatment.
The dentist. To minimize dental disease odds, patients should enter cancer treatment with their teeth and gums in the best shape possible. Before beginning treatment, then, the dentist can assess their oral health status and recommend a treatment plan for any existing disease or condition. The dentist can also monitor a patient’s oral health during the treatment period.
The patient. Patients can do the most to protect their oral health by removing disease-causing plaque buildup with daily brushing and flossing, as well as maintaining their regular schedule of dental cleanings (if possible). They should also attempt to reduce dry mouth, a potential consequence of cancer treatment, by consuming more water and using saliva boosters like Xylitol-sweetened gums and mints. A nutritious diet is also important for protecting oral health.
The caregiver. Many cancer patients depend on family or friends to aid them during treatment. One of the best things a caregiver can do is act as a liaison between the patient and their medical and dental providers. When it comes to oral health, caregivers should be on the alert for any mouth changes including tooth pain, gum swelling or bleeding, foul breath and other signs of disease.
Focusing on oral health can be a daunting challenge for patients during their fight with cancer. But with help from their other partners, they can come out of this fight with their teeth, gums and mouth in good health.
