Protecting Your Gums Before It's Too Late
Periodontitis is an infectious gum disease that, left untreated, can lead to tooth loss. Yet when it is detected and managed in time, it is entirely possible to stop its progression and regain stable oral health. At Centre Dentaire Dentown, this care is provided by a dentist who specializes in periodontics, whose expertise supports thorough, personalized treatment.

Why Can Gums Become Infected?
Gums play an essential role: they protect and support your tooth roots as well as the bone that holds them in place. When bacteria build up between the tooth and the gum, inflammation develops — this is gingivitis. If left untreated, this inflammation can progress to periodontitis, a deeper infection that causes periodontal pockets to form. These spaces between the tooth and the gum become a haven for bacteria, whose toxins gradually attack the periodontal ligament and the alveolar bone, causing tissue destruction that can lead to tooth loss.
Several factors can contribute to this progression:
- Insufficient or inadequate oral hygiene
- A genetic predisposition to periodontal disease
- Smoking, which reduces the gums' natural defences
- Diabetes or certain other systemic conditions
- Cleanings spaced too far apart, allowing tartar to build up
Warning signs to watch for include gums that bleed when brushing, red or swollen gums, persistent bad breath, receding gums, or teeth that feel loose. Note that periodontitis can also progress without any noticeable pain, which makes it a particularly deceptive disease.
How Periodontal Treatment Unfolds
After a complete periodontal evaluation, including an assessment of gum pockets and an X-ray exam, our periodontist puts together a treatment plan tailored to your situation.

- Scaling and root planing: a deep cleaning below the gumline to remove plaque and tartar that have built up on the roots.
- Local antibiotic treatment: if needed, antibacterial agents may be applied directly into the periodontal pockets.
- Periodontal reassessment: a few weeks after treatment, a new evaluation measures how the tissue has responded and allows follow-up care to be adjusted.
- Periodontal maintenance: a regular follow-up program is put in place to prevent recurrence and stabilize the results achieved.
- Periodontal surgery: in advanced cases, a surgical procedure may be recommended to access hard-to-reach areas and support tissue regeneration.

A Specialty That Makes All the Difference
Seeing a periodontist means benefiting from three years of specialized university training beyond the doctorate in dental medicine. This level of expertise translates into a more precise diagnosis, more advanced treatment techniques, and better long-term outcomes. Our specialist works closely with your treating dentist to ensure optimal continuity of care.
Periodontitis does not resolve on its own, but it can be very well controlled with the right care. The earlier it is addressed, the better your chances of keeping your natural teeth.

Treatment is performed under local anesthesia. Mild sensitivity may persist for a few days afterward, but the procedure itself is generally well tolerated.
This varies depending on the severity of the disease. A moderate case may require one or two visits, while more advanced cases can require several appointments and long-term follow-up.
