What are dental crowns?

January 2nd, 2025

A dental crown is often called a “cap.” A dental crown covers all of the visible parts of the tooth and has many functions and reasons for placement.

There are several different types of crowns available at Fabre Family Dental Care of Marrero. They vary in their material, appearance, and functionality. A PFM, or porcelain fused to high-noble metal, is the most common. A full cast, high noble metal crown is a gold crown, and a stainless-steel crown is meant to be temporary. The most natural-looking crown is one that is all porcelain. These are often used for front teeth.

Getting a crown typically requires two appointments. The first is a preparation with impressions, shaping, and placing a temporary. The impressions are either sent to a dental lab, where the process generally takes two weeks, or done in-office with a machine that can make a crown without needing a second appointment. These crowns are made from a high-quality solid block of porcelain. The shape of the tooth is constructed from a digital 3D image of your tooth.

To accurately determine which type of crown is best, you must first know why you need the crown and in what area of your mouth is it needed, which can be answered when you visit us at Fabre Family Dental Care of Marrero. For instance, if you have a gold crown on the lower right and need a new crown directly above on the upper right, the best durability and long-lasting relationship is another gold crown.

If you need a crown on a front tooth, a gold crown may not be the best choice. A PFM has strength but is not ideal, as a dark line will appear at the gum line. A full porcelain crown is going to look as close to a natural tooth as possible, but will have less strength than a gold crown.

There are two types of porcelain crowns, depending on how they are made. A dental lab makes a full porcelain crown by baking layer upon layer to make the porcelain look like natural enamel. A full porcelain crown made in-office out of a solid piece of porcelain will have increased strength. However, the natural layered appearance is extremely difficult to achieve.

A crown is placed on a tooth when added strength is needed. Cracks, large broken-down fillings, or previous root canal treatment are all conditions where a crown is the standard care. The type of crown that is most appropriate depends greatly on location.

Digital X-rays

December 26th, 2024

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. Keith J. Fabre Jr. 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 Marrero office. We’re happy to explain the science—and the benefits—of high-tech radiography.

The Link Between HPV and Oral Cancer

December 26th, 2024

Cancer has become a common word, and it seems like there is new research about it every day. We know antioxidants are important. We know some cancers are more treatable than others. We know some lifestyles and habits contribute to our cancer risk.

Smoking increases our risk of cancer, as does walking through a radioactive power plant. But there is a direct link to oral cancer that you many may not know about—the link between HPV (Human Papilloma Virus) and oral cancer.

This may come as a shock because it has been almost a taboo subject for some time. A person with HPV is at an extremely high risk of developing oral cancer. In fact, smoking is now second to HPV in causing oral cancer!

According to the Oral Cancer Foundation, “The human papilloma virus, particularly version 16, has now been shown to be sexually transmitted between partners, and is conclusively implicated in the increasing incidence of young non-smoking oral cancer patients. This is the same virus that is the causative agent, along with other versions of the virus, in more than 90% of all cervical cancers. It is the foundation's belief, based on recent revelations in peer reviewed published data in the last few years, that in people under the age of 50, HPV16 may even be replacing tobacco as the primary causative agent in the initiation of the disease process.” [http://www.oralcancerfoundation.org/facts/]

There is a test and a vaccine for HPV; please discuss it with your physician.

There are some devices that help detect oral cancer in its earliest forms. We all know that the survival rate for someone with cancer depends greatly on what stage the cancer is diagnosed. Talk to Dr. Keith J. Fabre Jr. if you have any concerns.

Please be aware and remember that when it comes to your own health, knowledge is power. When you have the knowledge to make an informed decision, you can make positive changes in your life. The mouth is an entry point for your body. Care for your mouth and it will care for you!

Diet and Dental Health: What to eat and what to avoid

December 19th, 2024

You are probably aware that guzzling soda and drinking those sugary Starbucks Frappuccinos aren’t particularly good for your dental health. But how much thought do you give to the effects of your diet on your teeth? Practicing healthy eating habits isn’t just helpful for your waistline, it also ensures that your teeth stay strong and cavity-free.

How diet affects dental health

Our team at Fabre Family Dental Care of Marrero will tell you that your mouth is a complicated place on a microbiological level. Harmful bacteria form dental plaques which convert the sugars in food to acids that wear away at tooth enamel. Meanwhile, saliva washes away some of the detrimental acids, while minerals work to rebuild where teeth are damaged. The foods you eat are important for managing this balancing act between harmful bacteria and helpful rebuilding agents.

Rethinking your diet to prevent cavities

Carefully considering your dietary choices is a smart way to become mindful of the foods you eat and how they affect oral health.

Foods to eat

  • Calcium- and phosphorus-rich foods. We’ve all heard that milk builds strong bones, and your teeth are included in that. Milk, cheese, nuts, and chicken are strong sources of calcium and phosphorus. These minerals are used to repair damage to the teeth’s enamel.
  • Crunchy fruits and vegetables. Biting into an apple stimulates saliva flow, which washes harmful acids from the surface of your teeth. Turn to other crunchy fruits and vegetables, including carrots, celery, pears, and lettuce, to increase saliva production.
  • Sugar substitutes. If you have a sweet tooth but want to decrease tooth decay, sugar substitutes such as Stevia or Equal provide a sugary kick without harming your teeth.

Foods to avoid

  • Sugary snacks. Cookies, cakes, candies, and other sugary treats provide a feast for the acid-producing bacteria in your mouth. Furthermore, these foods often get stuck in the ridges of your teeth, and provide a breeding ground for new bacteria.
  • Acidic fruits and vegetables. Foods high in acidity, such as tomatoes, citrus fruits, berries, peaches, and lemons, wear away the enamel of your teeth. Because these foods can be part of a healthy diet, remember to brush after eating them or swish with a mouth rinse to protect your teeth.

Eating well is an essential part of keeping your teeth healthy. Consult Dr. Keith J. Fabre Jr. about your diet for tips on food habits that keep your teeth strong and cavity-free.
