Frequently Asked Questions (FAQs)

How can we help you?

We love hearing from our patients and answering their questions. If you have a question, contact our dental office, or check out some of the questions we hear most often below. 


Our office uses digital radiography for the ease and comfort of our patients. Digital x-rays are also safer and better for the environment compared to traditional films. They emit far less radiation, and because no chemicals are used, they are considered a greener option.

These digital images appear quickly without the use of a dark room, which means less waiting. They are also easier to store electronically. Your dentist is able to share these images with you, explain your oral health issues, and this helps you make informed choices for your smile.

X-rays allow us to see parts of your teeth that are under the gum tissue and in the bone. It is very important for us to monitor those areas as well to help you maintain optimum oral hygiene. Your dentist can also use the images to treat dental problems and plan treatments with accuracy.

In our Lansing, MI dental office, we like to refer to technologies that are patient-friendly, safer, and allow for the best possible outcomes for our patients.

General Dentistry

Tooth decay is one of the most common and preventable oral health diseases, affecting both adults and children. Unfortunately, not everyone has had access to quality dental care or understands how decay forms and spreads.

The bacteria in your mouth need fuel to survive, and they get this fuel from the foods you eat and the sugars within them. When the bacteria feed on sugar, they create an acidic byproduct. Acid softens the enamel of teeth and dissolves it away, which exposes teeth to damage.

Brushing and flossing help protect your teeth by removing the food particles that the bacteria feed on. Though no matter how diligently you take care of your teeth, some plaque will collect. This is why regular dental cleanings are so important.

When decay occurs, it will need to be removed and your tooth will need a filling. The filling replaces the decayed tooth structure that was removed.

Your dentist in Lansing, MI uses a durable, tooth-colored filling material to restore your teeth and allow them to have a natural look. This means no metal or silver.

If you have a cavity or are looking to replace your older silver fillings, ask a team member about our quality tooth-colored fillings.

The idea of a root canal is very intimidating to some patients, but in reality, they are incredibly beneficial in saving a tooth and easing pain. Root canal therapy is a much better experience today than it used to be as well. Dr. Johnston, your dentist in Lansing, MI, has implemented some of the latest technologies to make the root canal process comfortable.

Sometimes a broken tooth or a tooth with a lot of decay will develop an internal infection. This can cause the tooth to become inflamed and very painful. It can become sensitive to temperatures as well. The infection can even cause a small hole in the gum tissue so that it can drain. If you notice any of these symptoms, including a blister on the gum, we encourage you to contact our dental office.

Remember, a root canal simply cleans the infection out of your tooth to promote healing. After numbing your tooth, Dr. Johnston makes a small access point on the chewing surface and then, using rotary instruments, clears out the infection, damaged nerve, and diseased tissue. He will finish by placing a special filling inside the canal to promote healing and seal the tooth.

After the root canal treatment in Lansing, we place a permanent tooth-colored filling—or a dental crown may be necessary to help protect the tooth and maintain its strength in the future.

Children's Dentistry

We see patients of all ages, including children!

It is very important to give children a great first experience in the dental office as it can be very intimidating to a child, and your child’s dentist in Lansing and his team try to take that aspect out and make it fun.

Your Child’s First Appointment

Just like adults, your child will meet with Dr. Mark Johnston first. This is a very simple exam where he says hello and gets to know your child. If your son or daughter allows, he will count their teeth and see if there is any decay.

For very young children, he will make sure their teeth are coming in properly and that their jaw health is sound. If we see that your child is nervous and does not want to open up, we don’t force it—this can lead to dental anxiety. We typically recommend your child come back on a different day.

Regular Dental Visits for Children

When age-appropriate, we clean your child’s teeth following their exam with Dr. Johnston.

When it comes to treating oral health issues in children, we can administer nitrous oxide if your child is nervous. This can help with anxiety, and the relaxation effects wear off quickly.

Crowns and Bridges

A crown is usually recommended when a tooth is at risk for fracturing following trauma or root infection. However, we can use dental crowns in a variety of treatments.

A dental crown is a cover that goes over a prepared tooth to the gum line. It is colored and shaped to match your surrounding teeth. In most cases, this is a tooth that already has fracture lines from heavy use, grinding, clenching, or a tooth that has a large filling. The prevents loss and further damage.

A dental crown can also conceal an unsightly tooth with stains or shape abnormalities in cosmetic dentistry.

In dental implant therapy, a dental crown tops your implant post and becomes your replacement tooth.

Dental crowns also secure a dental bridge to healthy adjacent teeth.

In our Lansing dental office, we rely on quality dental crowns to contribute to your smile health and aesthetics.
