Gum recession is the process in which the margin of the gum tissue that surrounds the teeth wears away, or pulls back, exposing more of the tooth, or the tooth's root.


There are a number of factors that can cause your gums to recession 

  1. Periodontal diseases.
  2. Aggressive tooth brushing
  3. Insufficient Dental care

Gingival recession is one of the causes of tooth hypersensitivity.


The coronally advanced flap (CAF) is a procedure frequently used for the treatment of gum recession. The main objective of this surgical technique is to mobilize the gingival margin and reposition it at a level more coronal (incisal direction) than its original location.


In this case, Miller's class 1 recession is treated with coronally advanced flap procedure (fig. 1)

Under local anesthesia, two horizontal incisions and two vertical incisions are placed around tooth as shown in figure 2.

After placing incisions, flap is raised coronally (fig 4) and sutured(fig 5). Ideally, 5-0 or 6-0 resorbable suture can be used for a better result. In this case, 4-0 Mersilk sutures were used.

Gum recession is a common gum problem and one of the causes of tooth hypersensitivity. 

Minor gum recession like Miller's class I can be successfully treated minor surgical procedure like a coronally advanced flap. Advanced gum recession like class II and Class III required a more advanced regenerative procedure.
