Gum & Jawbone Corrective Treatments

Gum & Jawbone Corrective Treatments

There are many reasons why the gums and jawbone may require corrective treatment, including periodontal disease, trauma and birth defects. Periodontal disease particularly, can greatly disfigure the natural appearance of the gums and teeth and give the smile an unaesthetic appearance.
New “cosmetic surgery” procedures are now available in periodontics, which effectively correct cosmetic problems and restore natural beauty to the smile.

Here are some of the most common gum and jawbone corrective treatments:

Common Gum Treatments

  • Crown lengthening (gum lift) – Crown lengthening is usually performed to correct a “gummy” smile, or to expose more of the tooth prior to a restorative surgery.  In some cases, the teeth look short and stubby and partly covered by gum tissue due to genetics or gingivitis.  Excess gum tissue can easily be removed to reshape the outline of the gums, expose the natural tooth length, and provide a fuller, more attractive smile.  The same procedure is also an excellent way to create a more aesthetic gumline for dental crowns and other restorative procedures.
  • Gum grafts – Gum grafts are generally performed to correct a crooked smile, or to restore symmetry to the gumline after periodontal disease has been treated.  Periodontal disease causes the gums to recede; making the smile look overly “toothy.”  During a gum graft, a thin strip of tissue is removed from the palate and stitched in place over the recession site.  Gum grafts are often used to re-contour the gum line and give the teeth a more pleasing appearance.
  • Pocket reduction surgery – Periodontal disease can cause the smile to be marred with unattractive teeth, brown gums and ridge indentations.  The aim of pocket reduction surgery is to clean the root surfaces of the teeth e subgingivally (beneath the gum line).  During this procedure, tartar, plaque and bacteria that are affecting the teeth and gums will be removed.  The gum is first gently separated away from the tooth, and then the calculus (tartar) and plaque are removed using special ultrasonic and hand instruments.  An antimicrobial liquid may be administered to the area to destroy bacteria colonies and ensure the pockets are given the chance to naturally heal.  Pocket reduction surgery is an effective way to restore health to the gums and bone.

Common Jawbone Treatments

  • Sinus augmentation – This procedure is usually performed prior to the placement of dental implants, to ensure that the prosthetic teeth are both functional and firmly affixed to the bone.  The success of an implant hinges on the quantity and quality of the jawbone to which it will be attached.  If the jawbone has receded or been injured, a sinus augmentation can slightly elevate the sinus floor to allow new bone to form.  Generally, a small incision is made in the bone and the underlying space is packed with grafting material.  The incision is sutured closed, and the implant will be placed when healing has occurred.
  • Ridge modification – Ridge modification procedures are used to treat deformities in the jawbone which have occurred due to periodontal disease, trauma or birth defects.  Birth defects particularly, can leave an unattractive indentation in the jaw, which makes placing dental implants difficult.  During the ridge modification procedure, the gum is gently pulled away from the bone to fully expose the defect.  The defect is filled with bone graft material or a similar synthetic product and then sutured closed.  When healing occurs, the cosmetic appearance of the jaw is much improved and implants can be successfully placed where necessary.
  • Bone grafts – There are a wide variety of reasons why a bone graft may be necessary.  Bone grafting thickens the jawbone to allow for the successful placement of implant anchors.  Bone grafts can also help elevate the sinus floor, fill craters or deformities in the jawbone itself, or allow for successful nerve repositioning.  The grafting material may be harvested from the lower jaw, the iliac section of the pelvis, or synthetically created.  In most cases, a small opening is made in the jawbone and packed with the bone graft material.  Sutures are placed and restorative treatments are performed when healing is complete.

If you have questions or concerns regarding Gum or Jawbone corrective treatments please ask your dentist.lengthening is generally performed in order to improve the health of the gum tissue, or to prepare the mouth for restorative or cosmetic procedures.  In addition, crown lengthening procedures can also be used to correct a “gummy” smile, where teeth are covered with excess gum tissue.  Crown lengthening exposes more of the natural tooth by reshaping or recontouring bone and gum tissue.  This treatment can be performed on a single tooth, many teeth or the entire gum line, to expose a pleasant, aesthetically pleasing smile.
Reasons for crown lengthening
Crown lengthening is a versatile and common procedure that has many effective uses and benefits.  The vast majority of patients who have undergone this type of surgery are highly delighted with the results.
Here are some of the most common reasons for crown lengthening:

  • Restoration of damaged teeth – Periodontal disease can cause severe damage to the teeth, as can trauma and decay.  Where teeth have been broken beneath the gum line, crown lengthening can be used to prepare the area for a new restoration to correct the damaged teeth.
  • Cosmetic uses – Extra gum tissue can make teeth look unnaturally short, and also increase susceptibility to periodontal infections.  Removing excess gum tissue can restore a balanced, healthy look and thus improve the aesthetic appearance of the smile.
  • Dental crowns – Crown lengthening serves to provide more space between the supporting jawbone and dental crown.  This prevents the new crown from damaging gum tissues and bone once it is in place.

What does crown lengthening involve?
Crown lengthening is normally performed under local anesthetic.  The amount of time this procedure takes will largely depend in how many teeth are involved and whether a small amount of bone needs to be removed, in addition to the soft tissue.  Any existing dental crowns will be removed prior to the procedure, and replaced immediately afterwards.
The dentist will make a series of small incisions around the soft tissue in order to separate the gums away from the teeth.  Even if only one tooth requires the re-contour, neighboring teeth are usually treated to provide a more even reshaping.  Separating the gums provides the dentist with access to the roots of the teeth and the underlying bone.
In some cases, the removal of a small amount of tissue will provide enough tooth exposure to place a crown.  In other cases, the dentist will also need to remove a small amount of bone from around the teeth.  The bone is usually removed using a combination of special hand instruments, and rotary instruments.  The rotary instruments roughly resemble the drill that is used in cavity treatment.
When the dentist is satisfied the teeth have sufficient exposure, the wound will be cleaned with sterile water and the gum tissue will be sutured with small stitches.  The teeth will look noticeably longer immediately after surgery because the gums have now been repositioned.
The dentist will secure the surgical site using an intraoral (periodontal) bandage, which serves to prevent infection.  Prescriptions may be provided for pain medication, and a chlorhexidine (antimicrobial) mouth rinse may be given to help reduce any bacteria attempting to re-colonize.  The surgical site will be completely healed in approximately two to three months.
