Your dental center in La Petite-Patrie - Periodontic Service

Periodontics is the dentistry branch that prevents and treats periodontal diseases, which are gum diseases. They are called periodontal because they affect the periodontium, the tissue supporting the teeth. Today, these diseases constitute the main problem bringing adults to see a dentist.

The main signs bringing a patient to see a dentist or a periodontist are :

  • A change in gum colour
  • A reddish colour
  • Bleeding gums while brushing
  • Receding teeth
  • A metal taste in the mouth
  • Swelled, painful or shiny gums
  • Sensitive teeth
  • Chronic bad breath

Periodontics Treatment Services

There are various periodontics treatments: pocket reduction surgery, regeneration surgery, gum graft, crown extension and nonsurgical treatment (like curettage).

Some studies show correlations between periodontal diseases and diabetes or heart diseases. Consequently, it is always essential to maintain a good oral hygiene in order to prevent periodontal diseases or other mouth diseases. Therefore, it is recommended to visit your dentist at least every six months.
