What Happens During a Teeth Cleaning and Exam?
The appointment has two halves that often get talked about as one thing. The cleaning is the hygienist’s work, and the exam is the dentist’s.
The Cleaning
Your hygienist starts by looking at your gums and noting anything that’s changed since last time. Then comes scaling, which is the removal of plaque and hardened tartar from the tooth surface and just below the gumline.
Scaling uses either a hand instrument, an ultrasonic scaler, or both. Tartar can’t be brushed off once it has hardened, which is the reason this appointment exists at all. Polishing follows, and it removes surface stain and leaves the tooth smooth enough that plaque takes longer to rebuild.
Most visits finish with flossing and, depending on your risk of decay, a fluoride treatment.
The Exam
Your dentist checks each tooth for decay, reviews any dental X-rays taken that day, and measures the depth of the pockets between your gums and teeth. They also screen the soft tissue of your mouth, tongue, and throat for anything that looks unusual.
If something needs attention, this is where it gets named and explained. A small area of decay usually becomes a filling, and catching it here is what keeps it from becoming a root canal later.
How Often Do You Need a Cleaning?
Twice a year is the interval most adults do well on, and it’s where our dentists start. Your own schedule comes out of your exam rather than out of the average.
Some patients are asked to come more often, usually 3 or 4 times a year. The common reasons are:
- A history of gum disease or deep pockets
- Smoking or vaping
- Diabetes
- Pregnancy
- Dry mouth caused by medication
- Heavy tartar buildup between visits
- Braces or other appliances that make home cleaning harder
If your checkups have been consistently clean and none of the above applies, your dentist may tell you twice a year is plenty. Asking is worth more than guessing.
What’s the Difference Between a Regular Cleaning and a Deep Cleaning?
These are two different procedures, and the distinction matters because the second one is treatment rather than prevention.
A regular cleaning, sometimes called a prophylaxis, works on the tooth surface and slightly below the gumline. It’s what a healthy mouth needs, and it’s usually done in a single visit.
A deep cleaning, called scaling and root planing, goes further down the root surface to remove bacteria from pockets that have deepened because of gum disease. It’s often split across two appointments, one for each side of the mouth, and the area is usually numbed. Your dentist recommends it based on measured pocket depth, not on how your teeth look.
NIDCR reports that close to half of adults aged 45 to 64 have some form of gum disease, so this recommendation is more common than most people expect. Being told you need one isn’t a sign you’ve done something badly wrong.
Does a Teeth Cleaning Hurt?
For most people a routine cleaning is uncomfortable at worst, and usually not even that. Sensitivity tends to come from two things: gums that are already inflamed, and exposed root surfaces where enamel no longer covers the tooth.
Tell your hygienist early rather than halfway through. They can switch instruments, work in smaller sections, or apply a topical numbing gel. If your gums bleed during the cleaning, that’s usually inflammation rather than anything the hygienist is doing, and it tends to settle once the tartar is gone.
If dental visits make you anxious in general, say so when you book. Our team can slow the pace and talk through each step, and some of our offices offer sedation options.
What Does a Teeth Cleaning Cost, and Does Insurance Cover It?
Preventive care is typically the best-covered category on a dental plan, and many plans cover 2 cleanings a year at a high percentage. What you pay depends on your plan, on whether X-rays are taken that day, and on whether the visit is a routine cleaning or scaling and root planing.
We’re in network with most major PPO plans. Coverage still varies by plan and by office, so ask us to verify your benefits before the visit rather than after, and our team will run that for you.
