When you think about dental care, you often imagine the dentist doing cleanings and treatments. But dental assistants play a key role behind the scenes. They help make each visit smooth, safe, and comfortable. Polishing teeth is one of their important jobs — it removes plaque, stains, and buildup, leaving patients with a cleaner, healthier, brighter smile.
What Polishing Does for Patients
Polishing does more than just improve appearance. It helps:
-
Remove surface stains caused by coffee, tea, tobacco, or medications.
-
Clear away plaque and biofilm that can lead to gum disease and cavities.
-
Make tooth surfaces smoother — which makes it harder for plaque to build up again.
-
Enhance the patient’s smile, boosting confidence and oral hygiene.
In Florida, trained dental assistants (with EFDA certification) may perform polishing — but only under the direct supervision of a licensed dentist.
How to Prepare for a Polishing Procedure
Before polishing begins, you need to get everything ready. Here’s what to do:
-
Gather and check equipment — Prophy cup and angle, polishing paste, handpiece (air‑ or electric), suction, air‑water syringe, gloves, mask, and protective eyewear.
-
Explain the procedure to the patient — Tell them what polishing does and how it feels; ensure they are comfortable.
-
Prepare the workspace — Arrange the tools, set up suction, and ensure hygiene and sterilization protocols are followed.
Step-by-Step: How to Polish Teeth Correctly
Lower Teeth First
-
Position the patient comfortably in the dental chair, leaning slightly back.
-
Attach the prophy cup to the handpiece and load a thin layer of polishing paste. Overloading can cause mess or poor control.
-
Use light pressure with the handpiece on slow speed. Polish in gentle circular motions; let the paste do the work — don’t scrub.
-
Work systematically tooth by tooth: molars first, then toward the front. Cover all surfaces (cheek side, tongue side, biting surface).
-
Use suction to keep the mouth clean and free of excess paste or water.
Rinse and Evaluate
-
After polishing the lower teeth, rinse and dry.
-
Check for any remaining stains or plaque. Re‑polish if needed.
-
Repeat the process for upper teeth using the same careful method.
After the Polishing: Post‑Care and Safety
Once polishing is done, take these steps:
-
Floss between teeth to remove any leftover paste from contact areas.
-
Offer a final rinse so the patient’s mouth is clean and comfortable.
-
Inspect the teeth for a smooth, shiny finish.
-
Clean and sterilize all reusable instruments and discard disposable barriers properly.
These steps help maintain oral hygiene and reduce risk of infection.
Legal & Safety Requirements in Florida
In Florida, polishing by dental assistants is only allowed if:
-
The assistant is formally trained and certified (e.g. EFDA certification).
-
A licensed dentist supervises the assistant during the procedure.
-
Proper infection control and sterilization protocols are observed (hand hygiene, sterilizing handpieces, using barriers, etc.).
Always follow current state‑approved safety and hygiene standards.
Why Polishing Matters — For Patients and for You
Polishing is more than a quick touch-up. It supports oral health, boosts patient confidence, and helps prevent future dental issues. For dental assistants, it’s a meaningful task that improves patients’ comfort and satisfaction with their smile.
With proper training, tools, technique, and safety practices, polishing becomes a valuable service. As a dental assistant, you help patients enjoy healthy, clean teeth — and feel good about their smile.
