What Determines How Long Your Cleaning Takes?

Plaque & Tartar Buildup

More buildup means more scaling time.

Gum Health

Time Since Last Visit

Patients who attend regularly usually finish faster.

Age & Dental History

Step-By-Step: What Happens During a Dental Cleaning?

1️⃣ Oral Examination

A dental hygienist checks your teeth and gums for inflammation, decay, or concerns.

2️⃣ X-Rays (When Needed)

Usually taken yearly to detect hidden problems.

3️⃣ Plaque & Tartar Removal

Scaling removes hardened buildup around the gumline.

4️⃣ Tooth Polishing

A gentle polish removes stains and smooths enamel.

5️⃣ Flossing

Clears debris and checks gum health.

6️⃣ Fluoride Treatment (Optional)

Strengthens enamel and helps prevent decay.

7️⃣ Dentist Review

Final check of bite, gums, and oral health.

Why Regular Cleanings Save Time (and Money)

Skipping visits often leads to:

Longer future appointments
Fillings or restorative work
Gum treatment
Higher dental costs

Preventive cleanings are typically the quickest and least expensive care option.
