Our Services

General Health Monitor

Your mouth is connected to the rest of your body and can be an indicator if other health issues are present. We keep track of your vital signs and other indicators so we can help you manage your whole body health.


Most general dentists provide restoration of implants ONLY. Dr. Johnson has been surgically placing and restoring implants for 10+ years and has more experience and expertise than any other dentist in Lewis County. When your dentist manages the placement and restoration of your implants, you can expect the best results in the finished product. We can replace single teeth, multiple teeth, or entire dentitions.

Gum tissue health and maintenance

Alicia and Shar are our two dental hygienist that are experienced in helping you maintain optimum oral health. They are responsive to your individual needs and love to develop a connection with each of their patients so our office becomes your comfortable dental home.

Blended Crowns and veneers

There are a variety of materials that we use to make your crowns. We have the ability to customize your crowns to match you natural teeth or use crowns to drastically transform your smile to perfection. From tooth colored crowns that won’t chip or break to naturally blended crowns that can’t be identified, we love to create beautiful smiles!

Tooth Colored Fillings

Composite fillings have been the standard of care in dentistry for quite some time now, but when placed on your front teeth, there is a definitive skill and attention to detail in layering required to achieve a beautiful natural result. We spend the time to create beautiful results which you’ll be amazed with.

Braces and Clear Aligners

We provide you with alternatives for improving your smile. Braces will correct heavy crowding, tooth rotations, spacing and bite discrepancies. Clear Aligners will correct the smaller irregularities, without conventional brackets and shorter treatment times.

TMJ & Bite Therapy

Dr. Johnson has continued his training in treatment of jaw joint pain and therapies. Do you have pain? Popping? Limiting jaw opening? Sore cheek and neck muscles? Do you get frequent head aches? Do you have difficulty sleeping? We will help you resolve your problem and provide long term solutions to help maintain your oral and general health.

Emergencies/ and Root Canal Therapy

If you have ever had a toothache, there is no getting away from it. We’ll get you in immediately and get you out of pain. Dr. Johnson will treat most root canals to completion and has experience managing dental emergencies. We want to be your doctor you can depend on when you need us most.

Dentures, Partial dentures & Bridges

There are many ways to replace missing teeth. Because we have had over 20 years of experience in providing these services, we provide you options that separate us from the others. We have creative solutions that make common restorations, like “Dentures” or “Partial Dentures”, exceptional. We strive to exceed your expectations in function, fit and natural appearance of all work and are interested in finding the best solution for each patient., We can help you understand the choices and plan for the best results.

Conscious Sedation & Nitrous Oxide

If you have dental fear or would just prefer to be less aware at your dental appointments, we offer various levels of sedations to help. Nitrous Oxide (laughing gas) has been used in the dentistry for 50+ years and is very safe for use with adults and children to ease dental anxiety. Conscious Sedation is the use of medication to moderately sedate patients so time and awareness become not a concern of the patient and helps eliminate even the greatest fear and anxiety. We have taking special training and obtained a special license to perform this method of sedation.

Digital X-rays/ Intra-Oral Cameras

We have up-graded our office to allow you to see what we see. With large screen monitor, the lowest exposure digital sensors, and intra-oral cameras, we can show you pictures and easily explain to you what we see in your mouth. Communication is as easy as just a few pictures. This helps explain treatment to get your deserved insurance benefits as well.

Dr. Marc lives in Centralia, WA and has raised his family here. He loves being outside being productive; whether working in the yard or garden, building or repairing something or just chopping wood. He loves to fish, golf, hike and ski at White Pass. He loves to spend time helping the community with his Rotary Club friends and helping people who get hurt on the ski slopes as part of White Pass Ski Patrol. Dr. Marc’s best days are those spent with his family…as a son, son-in-law, brother, brother-in-law, father and step-father, and now a grandfather.

I welcome all new patients to my practice and home away from home. I love to help to people learn what modern dentistry is capable of providing and knowing I can help them achieve these goals.

Outside of work, I enjoy working in my yard. I love a great book, sitting in the sun, and spending time with friends and family.

On a personal note, I am a lifelong resident of this community. I was raised here in Centralia, and graduated from Centralia High School, many years ago. I’ve been married to my husband, Mike for 23 years. I’ve been blessed with two beautiful daughters, ages 19 and 16. My family is my life! When I’m not working, I’m usually off spending time with my family. We spend most of our summers traveling to tournaments, spending countless hours at softball fields, watching our daughter play. We also like to spend time outdoors, enjoying the sights our beautiful Pacific Northwest has to offer, or hanging out at the fire pit, roasting marshmallows with family and friends.
