Amalgam Fillings vs. White Fillings
August 15th, 2017

Many varieties of fillings are available at our Highland, IN office. Most people are familiar with traditional amalgam fillings: those big silver spots on top of teeth.
Made from a mixture of silver, tin, zinc, copper, and mercury, amalgam fillings have been used to fill cavities for more than 100 years. They offer several advantages, including:
- High durability for large cavities or cavities on molars
- Quick hardening time for areas that are difficult to keep dry during placement
- Reduced placement time for children and special-needs patients who may have a difficult time keeping still during treatment
Although dental amalgam is a safe and commonly used dental material, you might wonder about its mercury content. You should know that when it’s combined with the other metals, mercury forms a safe, stable material.
The American Dental Association, U.S. Centers for Disease Control and Prevention, U. S. Food and Drug Administration, and World Health Organization all agree that based on extensive scientific evidence, dental amalgam is a safe and effective cavity-filling material.
White Fillings
Newer, mercury-free, resin-based composite fillings (white fillings) are also available at our Highland, IN office. Composite resin fillings are made from plastic mixed with powdered glass to make them stronger.
Resin-based fillings offer several benefits for patients, including:
- They match the color of teeth
- Less tooth structure needs to be removed than with amalgam fillings
- BPA-free materials can be used
Resin-based composite fillings also have some disadvantages, including:
- Higher cost than amalgam fillings
- Inlays may take more than one visit
- Requires more time to place than amalgam fillings
There’s a lot to think about when you have to get a cavity filled. We recommend you do your homework and speak with Dr. Rick Johns before deciding what’s best for you or your family.
What to do about Dry Mouth
August 8th, 2017

Xerostomia, commonly known as dry mouth, is a condition in which the salivary glands in the mouth don’t produce enough saliva. Saliva keeps the mouth moist and cleanses it of bacteria. A lack of it makes for an uncomfortably dry mouth that is also more susceptible to infection and disease.
Symptoms of dry mouth include:
- Dryness or a sticky feeling
- Frequent thirst
- Burning sensations or redness in the throat or on the tongue
- A sore throat or hoarseness
- Difficulty chewing, swallowing, or tasting food
Dry mouth usually comes about as a side effect of certain medications or medical conditions, but can also be caused by damage to the salivary glands because of injury or surgery.
If you're experiencing any of the symptoms of dry mouth, here are a few tips for what to do:
Double-check medications: If you are taking any prescription or over-the-counter medications, speak with Dr. Rick Johns to see if any of these could be causing the dry mouth as a side effect.
There may be ways to alleviate the symptoms.
- Stay hydrated: Whether you have dry mouth or not, it’s essential to stay hydrated. Drink plenty of fresh and pure water throughout the day. A good rule of thumb is to drink eight eight-ounce glasses of water a day.
- Suck or chew on a natural, sugar-free candy or gum: Sucking on candy or chewing gum will keep your salivary glands producing saliva. Healthier versions of sugar-free candy and gum are available these days. Some are made with xylitol, a sugar alcohol that actually helps prevent tooth decay.
- Add moisture to your living spaces: Try adding a vaporizer to your bedroom or the rooms where you spend the most time. It’s best for your home to have a humidity level of between 40 to 50%. Anything less than 30% is too low. You can measure humidity with a hygrometer, which is easy to find at your local department store or online.
These are just a few general tips, but if you’re experiencing the symptoms of dry mouth often and it’s interfering with your life, pay a visit to our Highland, IN office. That way you’re more likely to get to the root of the problem.
How Computers Help Dental Implants Look Natural
August 1st, 2017

Never before have dental implants looked as natural and aesthetically pleasing as they do today. With the help of computer-aided design and computer aided manufacturing (CAD/CAM), Dr. Rick Johns and our team are able to create implants with impeccable fit and finish. Although these technologies have been in use since the 1980s, it's only recently that they became efficient and cost-effective enough to be useful.
Dr. Rick Johns can also take digital scans of your teeth, providing a much more in-depth and accurate representation of them when compared to traditional X-rays. This scan can be used to create a physical model of your teeth through the use of 3D printing technology, allowing for the utmost in accuracy when planning your implant treatment.
Since each of our patients are unique, these CAD/CAM technologies offer a highly customized approach to implant dentistry that helps avoid the "one-size-fits-all" ways of the past. The goal is to have an implant look and function as closely as it can to the tooth it's replacing. That’s why these implants are typically milled using ceramic or composite resin — materials chosen due to their durability and resemblance to teeth.
Even the planning of your surgery can be aided and guided by computers. 3D CT scans create a digital representation of your mouth including all significant anatomical markers. This data is imported into planning software which, coupled with CAD/CAM implant technology, is able to 3D print surgical guides that snap into place over a patient's teeth. This means less risk for surgical error and much more accurately placed dental implants.
The main benefits of CAD/CAM dental implants are that they:
- Are extremely accurate for every patient, down to 50 micrometers
- Have better long-term results and more natural-looking implants
- Can be manufactured quickly, the same day in many cases
Of course this is just a quick summary of the benefits, and a computer-modeled implant may not always be the best option. If you have questions about the dental implants or the technologies we use to make them look as natural as possible, feel free to contact our Highland, IN office.
Dental Implants vs. Natural Teeth
July 25th, 2017

If you're considering getting an implant, you'll most certainly have questions for Dr. Rick Johns. You might be wondering how a dental implant compares to a real tooth. Let's look at some of the differences between implants and natural teeth.
It should be noted that one of the primary goals of implant dentistry is to try to provide the same form and function as your natural teeth. However, with that in mind, know that an implant is not a tooth. An implant does not decay and does not have dental pulp or periodontal membrane like teeth.
An implant won't always work in every case, but they do have some great advantages when they are called for. Some advantages of an implant:
- Often last for decades without needing to be replaced
- Create a functional and aesthetically pleasing replacement for your missing tooth
- Don't require surrounding teeth for support
- Do not decay like natural teeth
- Can be fixed or removable
- Are able to replace single tooth or multiple teeth
There are downsides to implants where natural teeth win out. The disadvantages of implants include:
- Higher cost compared to traditional dentistry
- It's a surgical procedure which requires a period of healing afterward
- Fracturing of fixtures and loosening of screws can occur (only in about 5% of patients)
- Since there is no cushion between the implant and the bone, fracturing of crowns and bridges is more common with implants than with natural teeth, though this is rare.
It's best to speak with Dr. Rick Johns about your options regarding implants. Let us know what you want to achieve and we'll work with you as best we can to accomplish that. And don't hesitate to contact our Highland, IN office for further questions about the procedure.
