X-rays are a vital diagnostic tool for any dental professional. X-rays help your endodontist perform a root canal, your orthodontist check the position of a tooth’s root, your oral surgeon discover a fracture. X-rays reveal what we can’t see with the naked eye—and that’s why they are an especially important tool for Dr. Ghenta as well.

Why Are X-rays Necessary?

There’s a lot going on below the surface. An X-ray can reveal such conditions as cavities between teeth or underneath fillings, abscesses and other infections in the bone, impacted wisdom teeth, and cysts and tumors. They can also show the size, shape, and density of the bone beneath the teeth, which is essential information for dental implant procedures or dentures.

How Do X-rays Work?

Traditional X-rays, or radiographs, make use of film just like traditional cameras. When you have an intraoral X-ray, for example, the film is sealed in a moisture- and light-proof packet, and placed inside the mouth to capture images of specific teeth and the bone around them.

The X-ray machine is aligned precisely with the film and an exposure is taken. The image at this point is latent, and won’t show on the film, because, just like photo film, traditional radiographs need to be chemically processed before they produce a visible image.

Digital technology, on the other hand, uses an electronic sensor instead of film. For an intraoral digital X-ray, a small sensor is positioned in the mouth just like a film. When the X-ray is taken, a digital image capture device produces an image which is formed by a matrix of pixels instead of a photo-like film exposure. This format allows the image to be sent directly to a computer for immediate display without requiring processing.

Even though these methods seem very similar, digital X-rays offer some significant advantages over traditional films. Let’s look at how they compare, more or less.

• More Diagnostic Advantages

A traditional X-ray is a fixed image. It cannot be modified or enhanced. Here the digital X-ray offers a clear advantage in diagnosis.

Just as you can enlarge certain types of images on your computer without blurring or losing detail, a digital X-ray uses computer software to magnify images while keeping their details sharp. They can also be enhanced through brightness and contrast applications to make details stand out even more. Both of these benefits are extremely helpful for diagnosis, especially when looking for small cavities, problems in the roots and surrounding bone, or developing wisdom teeth.

There is even digital subtraction radiography software available that can be used to compare recent images to older ones, removing (“subtracting”) all the similarities in the two images to display only the changes in the two—even small changes—that have taken place over time.

• Less Exposure to Radiation

Dental X-rays expose patients to very low levels of radiation, and modern technology means traditional X-rays expose patients to less radiation than ever before. Even so, digital X-rays have significant advantages. Radiation exposure can be reduced by an additional 10%, 20%, or more with a digital radiograph.

• More Convenient for Sharing and Transmitting

If you need to share your X-rays with another dental specialist or physician, digital technology allows you to simply have them e-mailed to another office or multiple offices. You no longer need to worry about preserving physical copies, either.

• Less Waste

Unlike traditional X-rays, digital X-rays don’t need to be processed, so you save time in the office. And while the processing time is not significant (usually several minutes), if you need to repeat some X-rays for a clearer picture, or require different images for several teeth, this time can add up.

Digital X-rays are also more eco-friendly.  The fact that they don’t need to be developed means that the chemicals used to process traditional films are no longer necessary—which also means that there is no need to dispose of chemical waste products afterward.

Our goal is to provide you with the safest, most efficient, and most effective dental treatment possible, and digital X-rays help us do that. If you have any questions about digital X-ray technology, contact our Dartmouth, MA office. We’re happy to explain the science—and the benefits—of high-tech radiography.

Dentine hypersensitivity can be described as a sharp and sudden pain caused by cold food and beverages. It’s present in more than half the population and result from receding gums that expose the root surfaces of your teeth.

That being said, hypersensitivity can be triggered by forceful tooth brushing, teeth whitening products, gum disease, and erosion from acid reflux, bulimia, or highly acidic foods. Symptoms can range from moderate to severe, depending on the cause and how quickly it’s treated.

Tooth sensitivity begins when the dentin develops some exposure. This layer that surrounds the nerve of the tooth is usually covered by gum tissue, but when recession takes place, the dentin can get exposed and the pain begins. The dentin contains numerous pores that run from the surface of the tooth inward. This direct connection to the nerve and blood supply of the tooth can be affected by external stimuli, such as the triggers cited above.

The good news is there are several different ways to treat dentinal hypersensitivity at Ghenta Dental Group.

Treatment of dentin tooth sensitivity begins by making an appointment with Dr. Ghenta. We encourage you to begin treatment sooner rather than later in order to figure out the cause and to reduce the pain you’re experiencing. In most cases, quick treatment options will solve the problem, including the use of desensitizing toothpaste, switching to a soft-bristled toothbrush, starting a daily fluoride rinse treatment, or minimizing teeth grinding with the help of a custom mouthguard.

For more serious cases, we may recommend you get crowns put on problematic teeth, start a gel or varnish fluoride treatment, or even schedule a surgical gum graft or root canal, depending on the cause and severity of your pain.

If you’re concerned about any tooth sensitivity you’re experiencing, please give our Dartmouth, MA office a call and schedule an appointment. Dr. Ghenta and our team want to help you identify the cause of your pain, and give you the best possible treatment plan. We look forward to seeing you to help alleviate discomfort and solve your tooth sensitivity.

Most people hear the word root canal and panic. With today’s state of the art equipment and improved local anesthetic devices, and some knowledge, a root canal does not have to cause panic. Root canals are a common dental procedure, done quite often at our Dartmouth, MA office.

Why do I need a root canal?

There are several reasons why Dr. Ghenta may suggest a root canal including:

• An infection in your tooth that has reached the nerves
• A deep cavity that cannot be filled because the pulp and nerves are also effected
• Injury to the tooth
• A deep cracked tooth
• Broken tooth
• Repeated fillings of the effective tooth

What is a root canal?

A root canal is a dental procedure that is used to prevent the loss of a tooth and relieve pain. Inside your teeth is pulp which consists of soft tissue blood, connective tissue, blood vessels, and nerves. When the pulp becomes infected, swollen or diseased a root canal is necessary to save your tooth. During a root canal, Dr. Ghenta will remove the infected pulp. The tooth’s root canals and pulp chamber of your tooth will be cleaned, so all the diseased pulp is removed and then your tooth will be sealed.

What to Expect During a Root Canal

Your root canal will start out just like any other dental procedure. We will go over any questions you may have, and then numb the area surrounding the tooth. After the area is numb the root canal will begin.

The amount of time it takes to do your root canal varies depending on number of roots that need to be cleaned. Most teeth have one root canal, while others have between two and four. For a single canal, the procedure usually lasts less than an hour. The more canals your tooth has the longer amount of time it will take and in some cases, you will require more than one visit.

How much pain will I have after a root canal?

Once the local anesthesia wears off, your pain can be controlled by over the counter pain medications such as Ibuprofen, Naproxen, or Acetaminophen. In some cases, Dr. Ghenta may prescribe a prescription dose of pain medication. Within two days you should be feeling much better and able to return to your regular lifestyle.

In years past, it was often recommended that dental patients who had a history of heart problems or other conditions, such as joint implants, be given antibiotics before any dental work. This pre-treatment is called prophylaxis, based on the Greek words for “protecting beforehand.” Why would Dr. Ghenta suggest this protection? It has to do with possible effects of oral bacteria on the rest of the body.

Our bodies are home to bacteria which are common in our mouths, but which can be dangerous elsewhere. If these oral bacteria get into the bloodstream, they can collect around the heart valve, the heart lining, or blood vessels. A rare, but often extremely serious, infection called infective endocarditis can result.

It is no longer recommended that every patient with a heart condition take antibiotics before dental procedures. Doctors worry about adverse effects from antibiotics or, more generally, that an overuse of antibiotics in the general population will lead to more strains of antibiotic-resistant bacteria.

There are some patients, however, who are at a higher risk of developing infective endocarditis, and who should always use preventative antibiotics. Generally, premedication is advised if you have one of these risk factors:

• A history of infective endocarditis
• Certain congenital heart conditions (heart conditions present since birth)
• An artificial heart valve
• A heart transplant

Your cardiologist will know if prophylaxis is advisable, and if you are taking any drugs which could interact with antibiotics. Always talk to your doctor about any dental procedures you are planning, particularly if they are invasive procedures such as gum surgery or extractions.

If you believe you would benefit from antibiotics before dental treatment at our Dartmouth, MA office, the most important first step is to talk with your doctors. We are trained to know which pre-existing health conditions call for prophylaxis, which dental procedures require them, which antibiotics to use, and when to take them. Tell us about any health conditions you have, especially cardiac or vascular issues, and any medication allergies. Working with you and your doctor to protect your health is our first priority, and having a complete picture of your medical health will let us know if antibiotic prophylaxis is right for you.
