Crown Lengthening

Crown 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.

Testimonials

I have been a patient of Dr. Jeffrey Weiner since 1981. His work is impeccable. He is meticulous and results focused. He is not happy unless you are happy. I have referred many patients over the year to his office. His staff is always accommodating and friendly. I have had to call him and his son Dr. Jason Weiner on weekends and holidays over the years for a dental emergency and they have both responded to me quickly and with concern and advice. I receive compliments every day about my smile and it is because of Weiner Dental.

Mary P., Bensalem, PA

I know from experience that patients at Weiner Dental are very fortunate in knowing that "the apple doesn't fall far from the tree." Dr. Jason Weiner is my primary dentist. He is not only adept in the painless and creative cosmetic work that he has performed on me, his easy manner and confident professionalism allays any anxiety that I may have about any dental problems. Having also been treated by Jason's father, Dr. Jeffrey Weiner, it is evident that a caring attitude and a healing aptitude has been passed on from father to son. That same demeanor seems to be instilled in everyone at Weiner Dental. I sincerely recommend the doctors and staff at Weiner Dental. I believe that they really care.

Edward M., Huntingdon Valley, PA

I have been going to Doctor Weiner for 30 years along with my wife and children. He has always given us the best of care. I do not know t oo many doctors who care so much that they call you at home to check on you. He cares about all people. When Dr. Weiner heard we were going to visit our daughter (who is a missionary in Jaraboca, in the Dominican Republic), he sent dental supplies for the folks down there. Most of them do not have the money for toothbrushes and toothpaste. If you could have seen the look of joy on their faces...it's hard to describe. And his son Jason is following in his father's footsteps. I not only feel like I have a great dentist but a good friend! Thanks Docs.
