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.
Patient Testimonials
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!
Thanks so much!
I hope all of my experiences continue to be positive and impressive.
Thank you again for the quick attention I was given.
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!
They take the time to make you feel comfortable and explain any treatment needed!!
Not sure if this got posted but had my next 6 month checkup. Staff friendly and efficient. Love this dental staff.
Then she took care of our grandsons and the had a wonderful experience, now they are not afraid of the dentist! Believe me when I tell you they were hesitant but now that opinion has changed. The toys she gave them were amazing, they played with them all day.
Friday bc I woke up in terrible pain and had a lot of swelling and they worked me in to get an X-ray and get some antibiotics.
I was greeted by courteous, helpful, friendly staff. Each staff member was competent in their job role. The Dentist was friendly and wasted no time in assessing my teeth and gums. I would highly recommend anyone to this dental office.
Staff is always very friendly!
Emily should get a raise!
All your staff are great.. please give them all raises!
Thank you!
Dr. Williamson was nice, too.
Dr. Williamson and Emily Outstanding .
Super Friendly Staff!
The fact that their office is brand new and super clean is a bonus too. Highly recommend them if you’re looking for a dentist.
This is a top-notch, well run office. Highly recommend for all ages!
The figures were within my ability to accept. Thank you Toni and good doc for refusing to sugarcoat a temporary fix.
Sincerely,
Kelly Schilling
If you're looking for dental services, give them a call!
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!
