Read reviews from your neighbors

“Typically I do not enjoy going to the dentist. Dr. Andy and his staff are so enjoyable that I look forward to getting my teeth cleaned! I appreciate all the staff I’ve encountered but mostly Christine; she deserves a raise! If you’re looking for a great dentist this is it!”

‑ Sadie H.

“Highly recommend Green Tree Dental to all my friends and family. My husband and I have both been seeing Dr. Andy for the past two years and highly recommend him and his team! The whole office is highly professional, great with scheduling and the appointments are always efficient and fast.”

‑ Kamie R.

“After moving from Chicago, I continued to make the 90 minute drive twice a year for my semi-annual cleanings. When my dentist retired I wanted to find someone closer to home. Dr. Andy, Ashley and Elle were a perfect fit. The office is professional, has all the latest technology and the staff thoroughly answered my questions.”

‑ Eric S.

“Dr Smith is awesome. Love that he doesn’t rush through the appointment. Takes the time to ask me if I have any questions. His hygienist, Anna, is fantastic! I finally found a dentist that my whole family likes going to!”

‑ Kelly B.

“I had a great experience this afternoon at Green Tree Dental. The staff was warm, welcoming and professional. I felt my cleaning was very thorough and all my questions were answered by Dr. Smith. My neighbor recommended Green Tree Dental and I’m happy to be a new client!”

“My experience was amazing! The staff was so professional and friendly. The environment was warm and cozy. First time I actually enjoyed having my teeth cleaned.”

‑ Marie W.

“I came to Green Tree and Dr. Smith for a second opinion. Dr. Smith took plenty of time to get to know what my concerns and hopes were and then reviewed and offer options/solutions. The entire staff made the visit painless, enjoyable, and I felt truly welcome. Their technology is the best I've seen and the people are better than the technology.

I've switched to Dr. Smith and Green Tree Dental.”

‑ Chris

“Excellent dental care! Beautiful, clean, peaceful facility. Hygienists are extremely nice, thorough and considerate. Dr. Andy is awesome! This dentist and the hygienists actually take the time to listen and answer any questions. Absolutely pleased with every aspect of this dental clinic. Highly recommend!”

‑ Cheryl Y.

“We have trusted Green Tree Dental for many years. When my sons moved away they both found that you can't trust every dentist. Dr Dowsett and now Dr Smith are very honest and fantastic Dentists. We also love the Hygienists. Sue has been cleaning our teeth for a long long time.”

‑ Heidi G.

“Great staff, Dr Andy is easy to get along with and does great work. Our whole family has been going to Green Tree Dental for years and we have no interest in changing. All smiles!”

Cosmetic Dentistry

Cosmetic dentistry is one of the most cost-effective ways to improve your appearance. A beautiful, bright, healthy smile will increase self-confidence and overall life satisfaction. Cosmetic dentistry includes things like tooth-colored restorations, dental implants, and crowns.

We have many options, so please call us today!

Dental Implants

Dental implants are a great option for replacing missing teeth, improving chewing ability, eliminating bridges, and replacing dentures.

Several implants may provide a base for a series of artificial teeth known as a fixed bridge. Implants can even be used to secure a full set of removable dentures for people who have no remaining natural teeth.

Invisalign® Orthodontics

Invisalign® Orthodontics Learn More

These “invisible” aligners are the latest in orthodontic technology for adults and teens. Straight teeth and a revitalized smile no longer need to come from a mouth full of unattractive wire and bracket braces. Enhancing self-esteem and physical confidence, invisible braces offer an aesthetic and barely visible alternative to conventional wire/bracket braces. Get the smile you've always wanted with Invisalign® Orthodontics.

One-visit Crowns

One-Visit Crowns Learn More

One-visit crown technology allows our practice to create tooth-colored porcelain restorations for healthy, beautiful smiles in a single appointment. Crowns should be placed before the tooth is so decayed that it may fracture. This can often help prevent the expense of root canal therapy in the future. If a tooth is too damaged to have a crown applied, a porcelain bridge may be a good alternative.

Smile Whitening

Smile Whitening Learn More

Many everyday things like coffee, tea and wine can significantly dull teeth. Smile-whitening enables us to significantly brighten your smile for that dazzling white smile you deserve. Plastic whitening trays will be made from models of your teeth. You will then place a special whitening gel in each tray and wear the trays in your mouth for several hours per day. (Many patients wear their trays after dinner and before bed.) A significant change in tooth color is usually seen in just four to six weeks.

Sleep Apnea Treatment

Tired of Your CPAP? Learn More

Obstructive sleep apnea occurs when the airway completely collapses, blocking airflow into the lungs. The harder one tries to breathe, the tighter the airway seals. This airway obstruction persists until the brain partially awakens the person, unconsciously closing the jaw and returning the tongue and throat to a normal position.

We offer effective, nonsurgical relief from sleep apnea and other sleep-related disorders—including snoring. Ask us how you can get the restful, healthy sleep you’ve been missing.

TMJ Treatment

If you suffer from headaches or pain, clicking or popping while chewing, there may be problems with your temporomandibular joint (or TMJ). Call us today to schedule a free TMJ treatment consultation.

Dentures & Partials

Dentures & Partials Learn More

A well made denture is not only comfortable and functions properly; it also allows the wearer to smile with confidence, knowing that their smile is no different than it would be with natural teeth. Creating a cosmetic denture is really an art in the hands of a skilled dentist like Dr. Smith.

Periodontal Therapy

Periodontal Therapy Learn More

Gum disease is treated by carefully removing the bacteria and substances that form in the pockets around the teeth. The removal of this material occurs on a microscopic level and requires great skill. Our dental team has had advanced training to effectively remove all of the bacteria.

Mercury Free

Mercury-Free Learn More

The common silver filling contains mercury. We use the highest-quality biocompatible, tooth-colored restorations to create healthy, beautiful smiles. Since the composite material adheres directly to the tooth enamel, less preparation of the tooth is required before using it. This means it is more durable and provides a more natural-looking result.

Patient Comfort

Patient Comfort Learn More

We customize treatment to each individuals' dental needs and health goals. Gone are the days of crowded waiting rooms and doctors hoping from room to room. We believe in giving individual one-on-one care.
