A "checkup" sounds simple, but a good one is a lot more than a quick look and a polish. This guide walks through what we actually do at a comprehensive dental exam, why each step matters, and how often most adults benefit from coming in.
The comprehensive exam
A thorough exam covers more than teeth. Your dentist looks at the gums, bone level, bite, jaw joint, and the soft tissues of your mouth and throat. A simple oral cancer screening is part of every adult exam, even if no one calls it that out loud.
Each tooth gets checked for decay, cracks, wear from grinding, and the health of existing fillings, crowns, and implants. Old work that is starting to fail is often caught here, well before it becomes an emergency.
X-rays and imaging
Two-dimensional X-rays show decay between teeth, bone loss, and problems around root tips that the eye cannot see. Frequency depends on your risk: most adults take a small set every 6 to 18 months, more if you have active issues, less if you are stable.
A 3D cone-beam (CBCT) scan is used when something more detailed is needed, such as planning implants, evaluating impacted teeth, or investigating jaw pain. It is not part of routine checkups.
The cleaning, in plain English
A "regular" cleaning removes plaque and tartar from healthy gums above and just below the gumline. A "periodontal" cleaning (also called scaling and root planing) goes deeper when gums are inflamed and tartar has built up beneath the gumline.
Why the distinction matters: doing only a polish on inflamed gums leaves the actual problem in place. Your hygienist measures pockets around each tooth and recommends the right type of cleaning based on what they see, not a one-size schedule.
The "risk" conversation
Modern dentistry is about identifying risk and managing it. At a good checkup, your team should talk about:
- Cavity risk (diet, dry mouth from medications, fluoride needs)
- Gum disease risk (genetics, smoking, diabetes, home care)
- Wear and grinding (TMJ tenderness, flattened edges, headaches)
- Existing dental work that may need attention this year or next
- Cosmetic concerns you have, even if you have not asked
How often should I come in?
Most healthy adults benefit from every 6 months. Patients with gum disease, frequent cavities, or complex restorative work often do better every 3 to 4 months. Kids on a stable, low-cavity track often do well at 6 months once their habits are set.
Frequency is a conversation, not a fixed rule. If your last cleaning felt unhurried and educational, you probably had a great checkup.
Patients on our membership plan get two exams, two cleanings, and a take-home whitening kit each year. It is built for adults without dental insurance.
Frequently asked questions
Do you take my insurance?
We accept most major PPO plans and file claims for you. See our insurance page or call the office to verify benefits before your visit.
What if I am nervous about the dentist?
Tell us. We take more time with anxious patients, walk through each step, and can offer sedation when it makes the visit possible. You can also send a question first if writing feels easier than calling.
I have not been in years. Will I get a lecture?
No. We focus on what you want to do next, not what you did or did not do before. The exam tells us where things stand; the plan we build together is the part that matters.
Do you see kids and adults?
Yes. Kids dentistry and adult care are both available at Lincoln Park and Schaumburg. Many families book back-to-back appointments.
