What to Expect During a Deep Cleaning

When bacteria and tartar collect below the gumline, the gums can pull away from the teeth and form deeper spaces called periodontal pockets. These areas are difficult to clean at home and can lead to continued inflammation and loss of the bone that supports the teeth.

A deep cleaning removes the buildup from these areas and makes the tooth roots easier to keep clean. This gives the gums an opportunity to heal and become less inflamed.

We will measure the spaces around your teeth and review any relevant X-rays to determine which areas need treatment.

Local anesthetic is usually used to make the appointment more comfortable. You may feel a brief pinch and pressure during the injection. As the area becomes numb, your lip, tongue or cheek may feel tingly, heavy or swollen.

Your dentist or hygienist will check that the area is adequately numb before beginning.

The hygienist will use an ultrasonic scaler, small hand instruments or both to clean above and below the gumline. The ultrasonic instrument makes a buzzing sound and sprays water. You will feel vibration, pressure and light scraping while suction removes the water and debris.

The root surfaces are then carefully cleaned and smoothed. This part of the procedure may feel similar to firm scraping or pressure, but you should not feel sharp pain. Raise your left hand if you feel discomfort or would like a break.

Inflamed gums often bleed during a deep cleaning. This is expected and usually decreases as the gums become healthier.

A deep cleaning may be completed on one side or one section of the mouth at a time. Dividing the treatment can make the appointment more manageable and leaves an untreated side available for chewing once the numbness has worn off.

Your mouth may remain numb for several hours. Wait until the numbness has worn off before chewing, and be careful with hot foods and drinks.

Mild gum tenderness, slight bleeding and sensitivity to cold can be normal afterward. As swelling decreases and tartar is removed, the teeth may look slightly longer or small spaces may become more noticeable. This does not mean the cleaning damaged the teeth.

Follow-up visits and periodontal maintenance cleanings are important because gum disease requires ongoing care. For home-care guidance, see our deep cleaning after-care instructions.
