How Long Will My Dentist Appointment Take?

Everyone has different dental needs, and is in our office for a unique reason, so the length of your visit will vary depending on what you’re visiting for. If you’re just in for a routine cleaning, exam, or consultation your appointment will most likely take somewhere around an hour. Periodontal cleanings and other more complex services will last longer, although the length still varies, treatment to treatment, patient to patient.

With that said, however, we do understand that life can be busy, and that having at least a decent idea of how long your visit will be can be incredibly helpful. With that in mind, if you are curious about how long your appointment will be, give us a call at (618) 400-0550 and one of our friendly team members will be able to provide you with the answers you’re looking for, so you can plan accordingly.

Smiling Together, Safely

When you visit Williamson Dental, we know that you are trusting us with not just your teeth, but with your health overall, and that’s something we don’t take lightly. To ensure the safety and well-being of our patients and team members, we follow CDC guidelines at all times, so you can feel comfortable during the entirety of your visit.

Dr. Williamson made me feel very confident from the moment we discussed my problem. I felt his concern for my issues were genuine. After 2 bad experiences with my previous dentist I decided to make an appointment for a second opinion on a partial plate that my previous dentist had made for me. It was very uncomfortable and ill-fitting. Dr. Williamson did some work on it which made a difference. He took time talking with me discussing my issues and reassuring me. He did not turn me over to a tech to handle the adjustment. I can highly recommend Dr. Williamson. All of his staff were warm and friendly. Everyone made me feel welcome. The office was clean and inviting.

Been entirely too long since I’ve been to a dentist due to a past experience with a horrible dentist and office. Made me not want to be near a dentist at all. Today’s visit was incredible. The tech I worked with listened to my plea of anxiety but made me feel very comfortable and at ease. We did X-rays and spoke between images as needed. Once the imaging was done she said she would get the dentist to go over the images and my teeth. We have determined I’ll need multiple cleanings as well as a filling for a cavity. But the staff and environment were so incredible that I felt so comfortable and at ease with the entire staff and facility. Beautiful facility with incredible staff. If you’ve ever had a bad experience at another place, this one will surely change that outlook completely

Great experience! From the time I walked into the office for my first appt and greeted by a friendly face, to my hygienist who was so kind, patient and made me feel so comfortable and at ease, to seeing Dr Haarmann who updated me on the results of my xrays and checked my teeth and gums. The experience was awesome! So happy we made the change.

As a Dental surgeon’s granddaughter, I am very particular about choosing an excellent dentist! I’ve been a regular patient of Dr. Williamson’s for nearly a decade!

Since being recommended to him, my dental care has been meticulous and relatively pain-free! This is partly because he also has an amazingly efficient and compassionate staff!

He’s very gentle, knowledgeable, and talented! One of my close friends was afraid to go to the dentist, and Dr. Williamson helped him feel comfortable and confident, and to overcome his fears!

The office is PERFECTLY clean and beautiful! It’s a calming and welcoming space that makes me feel like I’m in a spa!
Please give Dr. Williamson’s office a try!
I promise… You won’t regret it!

Very, very nice staff. I had nurse Kenzie helping me out with my teeth cleaning, and I highly recommend her. I struggled with keeping up with taking care of my physical health and teeth being one of them. Now that I am pregnant, I have had struggles regarding keeping my teeth and gums. Kenzie didn’t judge or question my teeth. She simply helped answer all my questions while also solving the problems I had going on. I came in, nervous about my teeth and me being judged, and walked out feeling confident in me and my smile. My teeth have been in so much better health as well as my teeth cleaning habits. Highly, highly recommend this place.

We moved to Columbia, IL a year ago and have found our new dentist!!

Prior to establishing Williamson Dental as our new dentist, I cracked a tooth about six months ago and needed immediate attention. Dr. Williamson and the entire staff were excellent in resolving my uncomfortable situation rapidly. Cracked tooth resolved without issue or repeat visits!

This week, I had my first semi-annual check-up at Williamson Dental. The front desk greeted me immediately upon my arrival and I was sent directly to the hygienist. . .no delay or wait! Hygienist was professional, thorough and provided one of the best cleanings I've ever had. Dr. Williamson was very knowledgeable and thorough in his examination. Made me feel like he had been my dentist for years! Very comfortable experience.

Thank you Williamson Dental!

This was my first visit to the new office in Columbia, IL. I had been a patient of Dr. Raney's for over 30 years. Happy for him, to have retired, but sad for me, as I don't change doctors when I find a good one. Well, I've now had an appointment with both Dr. Williamson and Dr. Haarmann, and happy to say, "Dr. Raney, the practice is in good hands!" Lovely new office and some new staff, all so pleasant and great service. Emily S was my hygienist at the most recent appointment. She was great.

Had my 6 month cleaning with a good eval. This is after a long ordeal with 2 abscesses which resulted in needing to have two back teeth extracted. Williamson Dental has been GREAT. They took care of me immediately and then referred me to an oral surgeon who did extractions and started the implant process. After the implant, Williamson Dental got me in right away to scan for the process of making two teeth which were ready two weeks later and now I am back to "normal". Thanks soooo much. I can eat again on the right side of my mouth?
Not sure if this got posted but had my next 6 month checkup. Staff friendly and efficient. Love this dental staff.

My husband had a temporary crown done this week and the tooth became abscessed a couple days later. Dr Haarmann was able to quickly prescribe antibiotics yet the tooth still needed a root canal asap. Dr Williamson spoke to him and triaged the situation Immediately. The root canal was scheduled and started by Dr. Williamson within an hour. We were both beyond pleased. Thanks so much for the personal and expedited procedure. 6 out of 5 stars for both Dr. Williamson and Robin who did a phenomenal job assisting.

The staff here could give the Swiss Railway a run for their money with their punctuality; they’re so on time, you’d think they have an internal clock set by the atomic clock in Colorado. Now, as for the dentist, his skills remain as mysterious to me as the Bermuda Triangle. Thanks to the superhero-level care I’ve received from the hygienist, my teeth are in such pristine condition that I’ve yet to experience the joy, or terror, of having the dentist poke around my mouth with his arsenal of tools. It’s a strange kind of disappointment, like buying a ticket to a monster truck rally and finding out it’s been replaced by a silent meditation retreat.

I've been going to the same dental care office for almost 30 years. To make this switch was huge for me. This was a very pleasant change. Staff was very kind and made sure I was comfortable. Met with Dr Williamson and I am very comfortable with the care he provides. Positive experience. Would highly recommend Williamson Dental.

This visit was the absolute best. I came face to face with thre fact that I needed more work on my teeth than I wanted to face. Not because I didn’t want restoration, but because of the dollar expense. While I was waiting for the proposal, I prayed for favor. I prayed the product I needed would be within my reach; I despise debt

The figures were within my ability to accept. Thank you Toni and good doc for refusing to sugarcoat a temporary fix.

I enjoy arriving at the office…Not only is it a beautiful dental office, everyone is friendly and helpful and I can tell they enjoy working there. I had such a great experience in Kenzie’s chair for my cleaning. She is so thorough and gentle cleaning my teeth she is a true professional! I can confidently say she has given me the best dental cleaning I have ever experienced. Dr. Williamson is also very kind, caring and professional. I have worked in Orthodontics most of my adult life so I have been around a few dental clinics in my years of experience. This office is at the top of my list for recommendations to my family, friends and acquaintances.
Sincerely,
Kelly Schilling

I hadn’t been to the dentist in over 7 years, so I was super nervous about going in for an appointment, but everyone was SO kind. My hygienist, Emily, did such a good job and I left with very little discomfort (which is pretty amazing, considering all I had done!) Aside from the great people, the office is beautiful and welcoming. Can’t recommend them enough!

The staff is always so nice to me and I feel as if I am given the red Capet treatment. I never worry about having any work done as the doctor is caring and always explains everything that he will be doing. I would and do recommend this office to anyone looking for a good dentist.

This was my first time going to Williamson Dental. My dental hygienist and Dr. Williamsom were extemely thorough, genuine, caring, knowledgeable, honest, and personable. They explained everything they were doing. We looked at my x-rays together and they described exactly what they saw. I felt educated after leaving, and my teeth felt more clean than they have in a long time. The ladies at the front desk were also very polite and professional. Everyone in the office made me feel welcome and important.

RUN don't walk! This office is fantastic!

We switched to Williamson dental years ago and I couldn't be more pleased with this dental office. Not only is every staff member kind and so patient, but they make you feel incredibly comfortable the moment you walk in the doors or call them. This coming from an adult with severe anxiety when it comes to dental work. They are wonderful with adults but when it comes to kids, there is no one else I would trust with my babies teeth. All three of my kiddos have seen Dr. Nathan and his fantastic staff since they were able to sit with me for my cleanings. If you are looking for a new dental office, don't hesitate to call them and setup your next
appointment!

I couldn’t be more satisfied. This staff went above and beyond to squeeze me into an opening on the day that I called, and I am a new patient, which was really a shock. The staff was by far the friendliest I have ever encountered at a dentist office. I highly recommend them to anyone.

Had a great experience today, my first visit. Visiting the dentist is always anxiety provoking for me. I felt so at ease and was treated wonderfully by all providers today. Know I made the right selection for a dentist.

My hygienist, Alexa, was awesome. It's her "fault" that my teeth feel so clean and polished. Everyone seems happy in this office; lots of smiling. New lobby furniture is very comfortable. I've been examined by all the docs, and they all have excellent chair-side manner. The staff takes notes on each visit on a personal level; this makes one feel comfortable when they call you by your nickname, and ask questions about you like you were just there yesterday, but it was (likely) 6 months ago. We come all the way from the car side of Carlyle Lake (a 1.5-hour drive) just to be seen by this top-notch team. Highly recommend!

Best staff and dentists I've ever done business with. They are always kind and attentive. I've never felt any judgment and they've never caused me any pain. They have reasonable hours and always get me in when necessary.
I chose this place because of great reviews and was not let down. The office is beautiful, calming and spacious - the lobby AND the individual patient rooms are very relaxing. Every single staff member was so kind. Emily the dental technician explained every part of the process to me and talked to me to help with my anxiety surrounding dental health. Looking forward to my future cleaning appointments here as I know I'll be taken care of.
