How long will a root canal last?
November 5th, 2019

According to the American Association of Endodontists, root canals have a success rate of over 95% and in most cases they last a lifetime.
There are a few factors that ensure the root canal will last and should be followed.
- You want to make sure you allow Dr. Rick Johns to perform a permanent restoration of the tooth. That means getting the filling and the crown immediately after the canals have been cleaned of all bacteria and debris.
- Practice good oral hygiene; that means brushing and flossing at least three times a day especially after meals and before bed.
- Just because a tooth has had a root canal that does not mean the tooth is safe for as long as it remains in your mouth. That tooth can still get a cavity. Since the nerves are no longer present in that tooth you will not feel any pain or experience any other signs of a cavity. That’s why it is important to get regular cleanings and checkups.
- If the tooth becomes fractured or you develop an abscess, you will feel pain and know there is a problem with the tooth.
Why do root canals fail?
As mentioned above, only about five percent of root canals fail, and sometimes it is not actually a “failure.” In cases, of teeth that have more than one root, it is possible that only one root was infected and filled. If the remaining root(s) become infected in the future, they will also need a root canal performed on them.
There are a few other reasons why your root canal may fail:
- The first reason is you may not have taken good care of your tooth (teeth). This is commonly seen in children and teens who often have inconsistent oral hygiene habits.
- If the tooth has more than one root, and one of the roots has a minute infection that is undetectable and goes unnoticed it can cause the root canal to fail. While this scenario is very unlikely, it does occasionally happen.
- Over time, the seal can become weak and bacteria can enter the tooth. This is also very uncommon but it does happen.
No procedure dental or medical comes with a 100% guarantee to last a lifetime, but if you take care of your treated tooth, the chances of success are great.

How a High-Tech Office Helps Your Dental Treatment
October 29th, 2019

A dental office on the cutting edge of technology offers numerous benefits to its patients. Whether you are in need of a simple cleaning or extensive restorative work, these technologies will help you stay more comfortable and give you better results than the outdated tools used in many offices. Here are some of the technologies that you can expect to see in our modern dental office:
- Digital radiography – Digital X-rays and imaging expose patients to far less radiation than traditional X-rays. Not only that, but these digital images provide a more detailed and easier-to-view snapshot of what is going on in and around your teeth. They make it easier for patients to see what's going on since we can show them right on the computer monitor. It's also better for the environment because there’s no need for the toxic chemicals used to develop traditional X-ray films.
- Panoramic X-rays – This digital X-ray gives Dr. Rick Johns a more in-depth understanding of the entire structure of your mouth and head than a regular X-ray. The panoramic X-ray machine rotates around your head and takes a 3D image of it, giving us a very complete picture that allows for more effective and timely treatment planning.
- Bioceramic implants, prosthetic devices, and sealants – Advances in implants and prosthetic devices over the past several decades has led to the creation of bioceramic (nontoxic) materials ideal for crowns, veneers, and implants. These materials allow for more visually appealing dental work since there are no metals used with these high-tech ceramics.
- Paperless bills and records – We all know the inconvenience of paper bills and receipts; they can create clutter and get lost. Our office has done away with this trouble by going paperless. This means you'll receive all your pertinent paperwork in your email inbox and records will be kept digitally at the office. No more wall full of patient records!
This is just an overview of the many advances that we’ve made to our Highland, IN office to make it cleaner, quieter, more comfortable, and more efficient, helping you spend less time in the chair and more time smiling!
Tooth Worms? The History of Cavities and Tooth Fillings
October 22nd, 2019

Scientists have discovered tooth decay in specimens that are more than 15,000 years old. The ancients once thought that cavities were caused by something called “tooth worms” … Eew! They didn’t exist, of course, but how else could humans explain the holes that cavities make in teeth?
The appearance of cavities on a widespread basis is often traced to the rise of farming. The new diet filled with grains and carbs made our mouths a haven for cavity-causing bacteria. As we added more sugar to our diets, our teeth got worse.
The “tooth worm” idea didn’t completely disappear until the 1700s when scientists finally began to understand the process of dental caries. Once that part of the puzzle was solved, they began focusing on filling existing cavities and preventing new ones.
Dental Fillings Come of Age
Many different materials, including beeswax, cork, aluminum, tin, and even asbestos, have been used to fill the holes caused by dental decay. Sometime in the mid-1800s, however, dentists began to use metal fillings such as gold, platinum, silver and lead amalgams.
The amalgam we use today is mixed from liquid mercury, silver, tin, copper, zinc, and other metals, but some patients still like the look of a gold filling. Newer options include composite-resin fillings, which are made from a tooth-colored mixture of plastic resin and finely ground glass-like or quartz particles that form a durable and discreet filling. Porcelain or ceramic fillings are natural in color, but more resistant to staining.
Dr. Rick Johns can help decide which filling is best for you, based on cost as well as your dental and lifestyle needs. You may not have “tooth worms,” but if you have cavities, contact our Highland, IN office so we can take the proper action to protect the health of your mouth.
Dental Sealants for Baby Teeth?
October 15th, 2019

Perhaps you’ve heard your friends talking about dental sealants, and how well they prevent cavities. And as soon as your child’s permanent molars come in, you absolutely plan to make an appointment at our Highland, IN office for this treatment. But should you also be concerned with your child’s baby teeth? Could they benefit from sealants too?
Even though those beautiful baby teeth are going to be replaced with permanent teeth, they should still be protected. Primary teeth help with speech development, enable your child to develop proper chewing and eating habits, and serve as place holders so that permanent teeth can erupt in the correct place. That’s why you’ve been so careful to help your child brush and floss twice daily, and make regular visits to our office for exams and cleanings.
But some teeth are just harder to keep clean with regular brushing than others. Primary molars, just like permanent ones, have depressions and grooves on the chewing surfaces. These grooves collect bacteria and food particles that are hard for bristles to reach, providing a perfect opportunity for cavities to develop in those little molars.
Cavities are not the only problem which can affect primary teeth. Because baby teeth have thinner layers of protective enamel, a cavity can actually reach the pulp (the center of the tooth) more quickly, leading to pain and potential infection.
While baby teeth can be treated, with fillings, restorations, and even stainless steel crowns, preventing tooth decay is always our first, best choice. And dental sealants are recommended by the American Academy of Pediatric Dentistry and the American Dental Association as one of the most effective ways to prevent cavities in both baby teeth and adult teeth.
Dental sealants are safe and effective. Sealants are thin coatings (usually a plastic resin or other dental material) that cover a molar’s grooves and depressions, making it impossible for bacteria and food particles to collect there. Applying them is a simple, pain-free process.
Each tooth will be examined first. If we find any signs of decay starting, we will gently treat that area before applying the sealant. After the tooth is cleaned and dried, an etching solution will be brushed on to the surface area being sealed. This etching roughens the surface so that the sealant will hold to the tooth more effectively. A thin coat of the sealant is then painted on and hardened under a curing light.
That’s all there is to it! Sealants typically last from three to five years, and some last even longer. Keep up your regular careful brushing and flossing, and we will monitor the condition of the sealants at each exam.
Talk to Dr. Rick Johns about dental sealants. We’ll let you know if your child can benefit from the procedure even before those baby teeth give way to permanent ones. It’s never too early to prevent tooth decay!
