How Long Does Deep Teeth Cleaning Take?
A deep cleaning, also known as scaling and root planing, is an important treatment to remove bacteria and tartar below the gum line and stop the progression of periodontitis. Many patients ask how long such a treatment takes, and the answer depends on several factors: the degree of gingivitis, the amount of tartar, and how many teeth are affected. On average, a deep cleaning takes between 1 and 2 hours – but sometimes it is performed over two or more visits.
The preparation: Examination and Planning
Before the treatment begins, the dentist or dental hygienist performs a thorough examination of the gums. The depth of the gum pockets is measured to assess how far the bacteria have penetrated along the roots of the teeth. If there are signs of periodontitis, a deep cleaning is planned. In some cases, X-rays are taken to see the bone level around the teeth.
The preparation itself typically takes 10-15 minutes, and during this time, the dentist explains how the procedure is done and what you can expect afterward. Since the treatment goes under the gums, local anesthesia is usually given so you don't feel any pain – just a slight pressure or vibration during the procedure.
The Treatment: Gentle Deep Cleaning
Once the anesthesia has taken effect, the actual cleaning begins. The dentist uses ultrasonic instruments to loosen tartar and flush away bacteria with water, then small hand instruments are used to clean and smooth the roots of the teeth. This process is called root planing and makes it harder for new bacteria to reattach.
How long this step takes depends on how much tartar is present and how deep the pockets are. For a patient with mild to moderate periodontal disease, the cleaning typically takes 30-60 minutes for one half of the mouth. That’s why many dentists choose to perform the treatment in two separate sessions so that each side of the mouth (left/right or upper/lower jaw) is treated thoroughly without overstressing the tissue.
The Aftercare: Rinsing and Instructions
After the cleaning, the area is often rinsed with an antibacterial solution, such as chlorhexidine, to further reduce bacteria. The dentist may also apply an antibiotic gel to the gum pockets to aid healing. You will then be given instructions on how to best care for your gums at home during the healing period.
This final step takes about 10-15 minutes, and the entire visit typically lasts 60-90 minutes in total. If two sides of the mouth are being treated, the total treatment time will be about 2-3 hours spread over two appointments.
Why the Treatment Should Not Be Rushed
A deep cleaning is a precise and gentle procedure, and it is important that the dentist works at a leisurely pace. Gums and tooth roots are sensitive structures, and proper cleaning requires time to ensure that all bacteria and tartar are removed without damaging the tissue. A thorough treatment provides the best healing result and reduces the risk of the inflammation returning.
After the Treatment
After the cleaning, your gums may be slightly sore or sensitive for a few days, but this is a sign that your body is starting to heal. You will usually be offered a follow-up check-up after four to six weeks, where your dentist will measure your gum pockets again to ensure that your gums are healing properly.
In Conclusion
The length of time a deep cleaning takes depends on the health of your mouth, but as a general rule, you should expect around one to one and a half hours per treatment. The extra time your dentist spends cleaning thoroughly and gently will pay off in the end: your gums will be healthier, tartar will be prevented from forming again, and you will reduce the risk of tooth loss. A deep cleaning is, therefore, not just a treatment, but an investment in strong and lasting oral health, so please schedule your next appointment with us, and we will help you take care of your smile!
