A teeth cleaning usually takes 30 to 60 minutes.
Time
A routine cleaning (prophylaxis) takes 30 to 60 minutes. A deep cleaning (scaling and root planing) takes 1 to 2 hours, often split into two visits.
What happens
- Examination and X-rays if needed.
- Scaling to remove plaque and tartar.
- Polishing.
- Flossing and fluoride treatment.
Frequency
The ADA says it depends on your needs; most people go every 6 months.
Cost
$75 to $200 without insurance. Most plans cover two cleanings a year.
Tips
Brush before you go. Tell the hygienist if you feel pain.
Gum disease
Cleaning more often may be advised.
Typical appointment length
A routine cleaning (prophylaxis) takes about 30 to 60 minutes. A first visit with exam, X-rays and cleaning can take 60 to 90 minutes. A deep cleaning (scaling and root planing) takes 1 to 2 hours per visit, and treats one or two quadrants of the mouth each time, so the full treatment often needs two to four visits.
What happens
- Examination of teeth, gums and soft tissue.
- X-rays, usually bitewings once a year or every two years for people at low risk.
- Scaling to remove plaque and tartar with hand tools and an ultrasonic scaler.
- Polishing with a gritty paste.
- Flossing and often a fluoride treatment.
- Review of home care and any problems found.
How often
Most dentists recommend a cleaning every 6 months. People with gum disease, diabetes, smoking habits or a history of cavities may need one every 3 to 4 months. Some low risk adults can safely go less often, based on a dentist’s advice.
Cost in the US
A routine cleaning costs about $75 to $200 without insurance. A deep cleaning costs $150 to $350 per quadrant. Most dental plans cover two cleanings a year at 80% to 100%. Community dental schools and public clinics offer reduced fees.
Tips for a comfortable visit
- Tell the hygienist if you are sensitive. Numbing gel is available.
- Brush before the visit if you like, but it is not required.
- Agree on a hand signal to pause.
- Bring headphones to ease anxiety.
Gum disease signs
Bleeding, swelling or a pocket depth of more than 3 millimeters indicates gum disease. Early disease responds to more frequent cleaning, and deeper disease needs scaling and root planing.
Aftercare
Teeth may be sensitive for a day or two. Avoid very hot or cold food if sensitive and keep brushing and flossing gently. After deep cleaning, gums may be sore for several days, and a warm salt water rinse can help.
Cleaning methods and what hygienists look for
A standard cleaning removes plaque and tartar (calculus) using ultrasonic scalers and hand instruments, followed by polishing and flossing. Hygienists measure gum pockets with a periodontal probe at six sites per tooth, where 1 to 3 mm is healthy. Bleeding on probing signals inflammation. Dental X-rays (bitewings) are usually taken once a year or every two years depending on risk. A cleaning for adults typically takes 30 to 60 minutes. A first visit with exam and X-rays may run 60 to 90 minutes. Without insurance, an adult cleaning commonly costs 100 to 200 USD in the US, and most plans cover two cleanings per year.
