Periodontal Plastic Surgery

Plastic gum surgery

According to the Canadian Dental Association, gum diseases (periodontal diseases) is the most common dental problem among adults. Not only is it important to brush our teeth well, but also to regularly visit your dentist for exams and professional dental cleanings.

The main signs leading to see a general dentist or periodontist for gum problems are:

  • A change in colour of the gums
  • A reddish colour
  • Bleeding gums when you brush
  • Exposed teeth root
  • A metal taste in your mouth
  • Swelled, painful or shiny gums
  • Sensitive teeth
  • Chronic bad breath

Please note, this list is not exhaustive. If you have a doubt, do not hesitate to contact us. Our general dentists offer periodontal services treatments.

Gum Treatments (curettage, grafts and removal of excessive gums)

The main gum treatments services offered at the clinic are periodontal pocket curettage and gum graft.

The goal of a gum graft is to remove a thin layer of tissue in the palate to place it underneath the gum at the base of the tooth. In some cases, a foreign graft may be used, avoiding to remove the gum from the palate.

Gum graft allows to proceed to the covering of exposed roots by assuring the regularity of the ridges.

The gum addition is done by the use of specific instruments. Lasers though, allow to clear the teeth where there is an excess of gum, therefore improving your smile. This procedure is done under local anesthesia and does not require convalescence for the patient, In addition, this surgery is sound and offers excellent long-term results.

For gum treatments and periodontal disease treatments in Montreal, contact general dentists from our dental office.
