Periodontal Tooth Scaling and Root Planing


Tooth scaling and root planing are the most common procedures for the treatment of periodontal disease (gum disease). For early stages of the disease (mild gingivitis), dental scaling and root planing are enough to help keep the gums healthy and firm. In more advanced periodontitis, the procedure acts as a necessary preparation before the required surgical treatments.

In many cases, good oral hygiene alone is not enough to prevent the accumulation of dental calculus below the gum line (sub-gingival calculus). Regular professional cleaning that includes periodontal scaling is needed to remove it.

Tooth scaling and root planing is a non surgical treatment that can be performed by a registered dental hygienist, a general dentist or a periodontist, sometimes referred as 'dental deep teeth cleaning'. It is a safe and routine procedure that should be performed as part of regular professional dental cleaning at least once a year.


What is Tooth scaling (dental scaling) & Root planing?

Tooth scaling is the procedure of scraping away the bacterial plaque and dental calculus (tartar) from the surfaces of the tooth, especially from the root surfaces below the gum line. Removing dental plaque and calculus during the regular preventive dental visits every 6 months, can help prevent most of the tooth decay and gum disease problems.


Root planing is the procedure of smoothing the root surfaces. If the root surface is rough it is much easier for bacteria and calculus to attach on it. Besides smoothing, the root planing removes any remaining plaque and calculus deposits trapped in these rough areas that could not be cleaned well by tooth scaling.


Importance of periodontal scaling and root planing for dental health

The tooth scaling and root planing procedure is necessary for the removal of dental plaque and calculus from the surfaces of the tooth, as part of a gum disease treatment. If they are not cleaned properly, the gums begin to get irritated and inflamed. The gums start to loose their firm attachment to the tooth and recede (gum recession). The space between the gums and the teeth widens and deepens forming periodontal pockets that promote further accumulation of plaque and calculus.
Up to this point, the condition is usually reversible by a tooth scaling and root planing treatment followed by good oral hygiene.
Further infection of the gums leads to severe periodontitis. The infection process results in extensive loss of gum tissue and jaw bone. In this case, only periodontal surgery treatment can restore some of the damage and save the tooth. Otherwise, the tooth looses its supportive tissues, loosens and finally falls off.
Scaling teeth and root planing are necessary procedures for treating periodontal disease when periodontal pockets are greater than 3 mm.


The tooth scaling and root planing procedure

If you have mild gingivitis, periodontal scaling and root planing is usually completed in one appointment. If there is a periodontitis problem more visits will be required. Your dentist or periodontist typically will be scaling the teeth at a quarter of your mouth (quadrant) on each visit. The tooth scaling and root planing procedure can cause serious discomfort in some patients, who have receding gums exposing the sensitive root surface or have dentin abrasions. Handling root areas of exposed dentin with dental instruments can be extremely painful. A local anesthetic is used to numb the area to be treated.
Periodontal scaling and root planing is usually performed with a combination of ultrasonic and hand instruments called dental scalers. Different instruments are used for different teeth, and even for different surfaces of the same tooth. Typically, ultrasonic scalers are used first to remove large deposits of plaque and calculus from the crowns and roots of the teeth. Ultrasonic instruments operate by vibrating the tip of the scaler in very high frequency, along with a water irrigating system used to remove the debris and cool the treated area. The vibrations can remove dental plaque and calculus without damaging the tooth’s surface.
Hand dental scalers then are used to complete the teeth scaling by scraping away any remaining calculus, especially from the pockets between the tooth and gums below the gum line. Hand dental scalers come in various shapes and sizes of the cutting edges with bladed, balled or pointed tips.
Finally the dentist will plane any irregular surfaces of the roots, so that the smooth surfaces make it more difficult for plaque to accumulate. This dental root planing procedure is very important in preventing similar problems in the future.
A smooth clean root provides a healthy environment to allow the gums to heal naturally and reattach to the tooth. This will create a reduced pocket, therefore eliminating areas for bacteria to hide and cause further disease.



Tooth pain after dental scaling and root planing

It is absolutely normal to experience some pain after teeth scaling and planing, especially if you had a tooth sensitivity problem before the procedure. Before the periodontal scaling some exposed dentin tubules might be covered by calculus ‘protecting’ them from external stimuli that could cause sensitivity pain. But after the calculus is scraped away the dentin becomes exposed again, explaining the incidents of increased tooth pain after tooth scaling and root planing procedures.
The removal of the irritating factors from the gums will decrease the gum inflammation. As a result the gums will seem to shrink and recede, in some cases, revealing a severe gum recession that might need surgical treatment.
For some days after the treatment, the gums may also feel sore and tender. Some gum bleeding during brushing can be expected for the first days.
Dentists may recommend an over the counter pain reliever to comfort the patient from the tooth pain after scaling and planing. An anti-microbial mouthrinse may also be prescribed if the patient feels discomfort during brushing due to sore gums. The tooth sensitivity may be treated by applying a fluoride varnish on the exposed areas of the roots.
