Regular Cleaning vs. Deep Cleaning: The Key Difference
The difference between a regular cleaning and a deep cleaning comes down to where the cleaning happens and why it is needed.
A regular cleaning, called a prophylaxis, is a preventive procedure. A dental hygienist removes plaque and tartar (hardened plaque) from the surfaces of your teeth and along the gum line. This is the cleaning most people get at their twice-yearly dental visit. It keeps healthy gums healthy.
A deep cleaning is a treatment, not a routine visit. It is prescribed when there are signs of gum disease, specifically when the gum tissue has pulled away from the teeth and formed pockets that trap bacteria. The procedure involves scaling (removing plaque and tartar from below the gum line) and root planing (smoothing the root surfaces so the gums can reattach).
When Is a Deep Cleaning Needed?
Your dentist or hygienist determines whether you need a deep cleaning by measuring the depth of the spaces between your teeth and gums. These spaces are called periodontal pockets.
What Pocket Depth Means
Healthy gums have pocket depths of 1 to 3 millimeters. At this depth, a regular cleaning is sufficient. When pockets measure 4 millimeters or deeper, it usually means bacteria and tartar have built up below the gum line where a regular cleaning cannot reach. This is the threshold at which most dentists recommend a deep cleaning.
Pockets of 5 to 6 millimeters indicate moderate gum disease. Pockets of 7 millimeters or deeper indicate advanced gum disease and may require additional treatment beyond scaling and root planing.
Signs That Gum Disease May Be Present
If you notice any of these signs, mention them at your next dental visit. Gum disease often develops without pain in its early stages, so it is possible to have it without knowing.
- Gums that bleed when you brush or floss
- Red, swollen, or tender gums
- Gums that have pulled away from the teeth (recession)
- Persistent bad breath that does not go away with brushing
- Teeth that feel loose or have shifted position
- Changes in how your teeth fit together when you bite
What to Expect During Each Procedure
Knowing what happens during each type of cleaning can help you feel prepared for your appointment.
What Happens During a Regular Cleaning
A dental hygienist performs most regular cleanings. The appointment typically takes 30 to 60 minutes. The hygienist uses hand instruments or an ultrasonic scaler to remove plaque and tartar from your teeth. After scaling, the teeth are polished with a gritty paste to remove surface stains. Flossing follows to clean between the teeth.
A regular cleaning is painless for most patients. You may feel some pressure or sensitivity if you have areas of tartar buildup, but anesthesia is not needed.
What Happens During a Deep Cleaning
A deep cleaning is a more involved procedure that is usually done in two visits, treating one half of the mouth at each appointment. Local anesthesia (numbing) is typically used to keep you comfortable because the instruments go below the gum line.
During scaling, the hygienist or periodontist removes plaque and tartar from the root surfaces below the gum line. During root planing, the rough spots on the roots are smoothed down. This smooth surface makes it harder for bacteria to reattach and allows the gum tissue to heal and reattach to the tooth.
Each appointment takes about 45 to 90 minutes depending on the extent of buildup. Some offices complete the entire mouth in one longer visit if the case is not severe.
Recovery After Deep Cleaning
A regular cleaning requires no recovery. You can eat and drink normally right after your appointment.
Deep cleaning recovery is mild for most patients. Your gums may be sore or tender for 2 to 5 days after the procedure. Some sensitivity to hot and cold foods is normal for up to a week as the gums heal. Over-the-counter pain relievers like ibuprofen typically manage any discomfort.
Your dentist or periodontist may recommend a prescription antibacterial rinse to help control bacteria during healing. Avoid hard, crunchy, or very hot foods for the first day or two. Stick to gentle brushing around the treated areas for the first few days.
Follow-Up After Deep Cleaning
Most patients return for a follow-up visit 4 to 6 weeks after deep cleaning. At this visit, the dentist or periodontist re-measures pocket depths to see how the gums have responded. In many cases, pocket depths decrease by 1 to 2 millimeters after successful treatment.
After deep cleaning, patients with gum disease typically need maintenance cleanings every 3 to 4 months instead of every 6 months. This more frequent schedule helps prevent the disease from returning.
Cost: Regular Cleaning vs. Deep Cleaning
A regular prophylaxis cleaning typically costs $75 to $200 for the full mouth. Most dental insurance plans cover two preventive cleanings per year at 100%, meaning no out-of-pocket cost for patients with insurance.
A deep cleaning typically costs $150 to $350 per quadrant (your mouth is divided into four quadrants). A full-mouth deep cleaning ranges from $600 to $1,400 total. Costs vary by location, provider, and the severity of the buildup.
Most dental insurance plans cover deep cleaning when it is medically necessary, usually at 50% to 80% after the deductible. If you do not have insurance, ask about payment plans. Many offices offer financing options.
When to See a Periodontist
A periodontist is a dentist who has completed 3 additional years of residency training in treating gum disease, bone loss, and other conditions affecting the tissues that support your teeth. General dentists and hygienists perform many deep cleanings, but a periodontist may be recommended in certain situations.
You may need a periodontist if your gum disease is moderate to severe (pocket depths of 6 millimeters or more), if deep cleaning alone has not improved your condition, if you have significant bone loss visible on X-rays, or if you need surgical gum treatment. A periodontist can also manage ongoing periodontal maintenance for patients with a history of gum disease.
