Root planing and curettage

Root planing and curettage are non-surgical procedures that remove the bacteria and tartar lodged in the periodontal pockets and along the roots of the teeth. The treatment is carried out under local anaesthetic and takes two to four sessions, depending on how severe the problem is and how many teeth are affected.

A non-surgical treatment for periodontitis

Root planing and curettage are non-surgical procedures that aim to disinfect tissues affected by periodontitis, by removing the bacteria and tartar lodged in the periodontal pockets and along the roots of the teeth.

Carried out alongside scaling, root planing allows the gum to reattach to the surface of the tooth once the treatment is complete.

Steps of the treatment

The treatment is done under local anaesthesia and requires two to four sessions, depending on how severe the problem is and how many teeth are affected.

  • the bacteria and tartar built up along the roots are removed using curettes, which are precision instruments, or an ultrasonic device
  • curettage is then performed to scrape the tissue inside the periodontal pockets
  • to complete the disinfection, the pockets may be irrigated with an antiseptic or an antibiotic

When to seek care

Gums that bleed, look red or swollen, breath that stays bad, teeth that look longer because the gum has pulled back, or a tooth that has become looser: these are reasons to have your periodontal health assessed.

The treatment is offered when the exam finds periodontal pockets, that is, a separation between the gum and the root where bacteria settle.

How the treatment works

The treatment is done under local anaesthesia, over two to four appointments depending on the severity and the number of teeth affected.

Each appointment treats one part of the mouth: the tartar lodged under the gum and along the roots is removed, then the tissue inside the pockets is curetted.

After the treatment

Sensitivity to hot and cold is common for a few days, because the roots are left with less deposit covering them.

What follows depends a great deal on daily hygiene: that is what keeps bacteria from recolonizing the pockets. A reassessment is scheduled to check how the gums responded, and cleanings are often spaced more closely afterwards.

Root planing and curettage treat advanced gum disease — periodontitis — without surgery: the bacteria and tartar lodged under the gum, along the roots, are removed so that the gum can reattach to the tooth. Gums that bleed, bad breath that persists, teeth that look longer or that move are signs to have assessed. Carried out alongside scaling, the treatment is done under local anaesthetic at our Repentigny clinic, which also welcomes patients from Charlemagne, Le Gardeur and L’Assomption.

Prevention and gum health

The care that helps maintain the health of your teeth and your gums over time.

  • An exam under way: the dentist’s mirror and probe move over the upper teeth.

    Dental exam

    A dental exam assesses the condition of the teeth, the gums and the tissues of the mouth. Done regularly, it helps catch a problem at an early stage, before it worsens and calls for a longer procedure. Depending on what it shows, the professional may recommend X-rays or specific follow-up.

  • An ultrasonic scaler and a mirror clean a patient’s teeth.

    Dental cleaning

    Professional dental cleaning, including professional scaling, removes the tartar and plaque that build up despite good daily hygiene. It helps prevent cavities, gingivitis and periodontal disease, while contributing to good oral health. The cleaning also comes with advice suited to your hygiene habits.

    Gum grafting

    In some patients the gum gradually recedes and exposes the root: this is gum recession. When it comes from an unsuitable brushing technique, simply reviewing that technique can be enough to stop it progressing. When a graft is the chosen option, it involves taking tissue from the palate and grafting it at the affected site.
