A routine cleaning is far more than a quick polish. Here is exactly what happens during your appointment, why each step matters, and how long it takes.
Step 1 - exam, charting, and X-rays
Your visit begins with a comprehensive review. The hygienist updates your medical history, takes blood pressure (yes, dental offices check this - it screens for hypertension and informs anesthesia choices), and performs an oral cancer screening. Digital X-rays are taken according to your risk schedule - typically bitewings yearly and a panoramic every 3-5 years. The dentist reviews the X-rays alongside the hygienist before scaling begins.
Step 2 - periodontal probing
The hygienist gently measures the gum pocket depth around every tooth - six measurements per tooth, recorded numerically in your chart. Healthy pockets are 1-3 mm. Pockets of 4-5 mm indicate early gingivitis; 6+ mm indicate active gum disease with bone loss. These numbers tracked over years are the single best predictor of long-term tooth retention. Probing is brief but the gums may feel slightly tender if there is inflammation.
Step 3 - scaling and ultrasonic cleaning
Scaling is the heart of the cleaning. The hygienist removes:
- Plaque - soft bacterial film, removed with hand instruments and an ultrasonic scaler.
- Tartar (calculus) - hardened plaque that has mineralized, removable only mechanically.
- Stain - surface discoloration from coffee, tea, tobacco, or foods.
The ultrasonic scaler uses high-frequency vibration plus water spray to break up tartar, especially below the gum line. It feels like a tickle or buzz; rarely uncomfortable on healthy teeth, slightly sensitive on gum-recession areas. Hand instruments finish detailed work between teeth and around margins.
Step 4 - polish, floss, and fluoride
After scaling:
- Polishing paste is applied with a slow rotary cup. This removes residual stain and creates a smooth surface that resists plaque adhesion. We use the lowest-grit paste appropriate for your enamel - overly abrasive paste is no longer the standard.
- Flossing - the hygienist flosses every contact point and identifies any tight spots, broken contacts, or persistent bleeders.
- Fluoride varnish is brushed onto the teeth. It tastes mildly resinous, sets in seconds, and stays effective for several hours. Skip eating or drinking anything hot for 30 minutes after.
Many cleanings end with a hygienist-led tutorial on any home-care issues spotted during the visit.
Step 5 - exam with the dentist
Dr. Cheung joins for the final 10-15 minutes:
- Reviews X-rays for cavities, bone level, and any pathology.
- Checks each tooth visually and with an explorer for soft spots, fractures, leaking margins, and wear.
- Examines the bite, TMJ, and tongue/throat for oral cancer signs.
- Discusses any findings and treatment recommendations.
- Answers questions and confirms your next recall interval.
If no work is needed, you are out the door with a fresh smile. If something needs attention, we walk through options, schedule, and insurance estimates.
Frequently asked questions
- Why do my teeth feel weird after a cleaning?
- Smooth surfaces after tartar removal feel different - many patients describe it as their teeth feeling "thinner" or "looser." That sensation passes within a day. Mild gum tenderness can also linger for 24 hours, especially if you had heavy tartar.
- Should cleanings hurt?
- A routine cleaning on healthy gums is typically painless to mildly tickly. Sensitivity around exposed roots or active gum inflammation can cause discomfort - let us know and we can use topical anesthetic or split the cleaning into two visits.
- How long should a cleaning take?
- A routine cleaning runs 45-60 minutes. A first visit (with comprehensive exam, full mouth X-rays, and probing) usually takes 60-90 minutes. Periodontal maintenance visits for patients with prior gum disease often take 60 minutes.
- What if it has been years since my last cleaning?
- No judgment - many of our new patients are years overdue. We may need a longer first visit or split the cleaning into two appointments if there is heavy tartar. We also check for any active issues that need to be prioritized.
