Crown Lengthening

What is Crown Lengthening?

Crown lengthening is usually performed to improve the health of the gum tissue, prepare the mouth for a procedure, or correct a “gummy smile”. A “gummy smile” is used to describe an instance where teeth are covered with excess gum tissue resulting in a less esthetically pleasing smile. The procedure involves reshaping or recontouring the gum tissue and bone around the tooth in question to create a new gum to tooth relationship. Crown lengthening can be performed on a single tooth, many teeth or the entire gum line.

Crown lengthening is often required when your tooth needs a new crown or other restoration. The edge of that restoration is deep below the gum tissue and not immediately accessible. It is also usually too close to the bone or below the bone.

Benefits of Crown Lengthening

Crown lengthening allows us to reach the edge of the restoration, ensuring a proper fit to the tooth. It should also provide enough tooth structure so the new restoration will not come loose in the future. This allows you to clean the edge of the restoration when you brush and floss to prevent decay and gum disease.

Crown lengthening takes approximately one hour but will largely depend on the number of teeth involved and if any amount of bone will need to be removed. The procedure is usually performed under local anesthetic and involves a series of small incisions around the tissue to separate the gums from the teeth. Even if only one tooth requires the procedure, it will probably be necessary to adjust the surrounding teeth to enable a more even reshaping. In some cases, removal of a small amount of bone will be necessary as well.

When sufficient teeth exposure is accomplished, the gums are sutured back to help secure the new gum to tooth relationship. Your teeth will look noticeably longer immediately after surgery because the gums have now been repositioned. You will need to be seen in one or two weeks to remove the sutures and evaluate your healing. The surgical site should be completely healed in approximately two to three months following the procedure. Crowns, if needed, will be done then.

Patient Review

My dad had tooth that was broken in half and it ached for months. We were referred to Dr. Zhu so we gave him a call and he kindly took us in to take a look. He took an x-ray and projected it to this huge tv in the room. He showed us what he saw and found that the tooth could not be saved. He explained the process in detail and answered all of our questions. We were able to quickly schedule a follow up appointment to remove the tooth. The appointment itself was great and my dad was so happy to have gotten the tooth taken care of. One week later the gums healed nicely and Dr. Zhu painlessly removed the stitches. I've seriously never seen such a nice dentist office before. They did a fantastic job building out their space and optimised it for patient comfort. The view out of the room was nice and peaceful which helped ease the stress of going to the dentist. My dad was thoroughly impressed and we would absolutely recommend Dr. Zhu to anyone in need of a periodontist.

Patient Review

Dr. Zhu was informative, knowledgable, kind, and went above and beyond! His huge smile is so welcoming when he walks into the door, and also very reassuring, because, let's be honest...I would run out the door if my Dr. walked in and had terrible teeth. You have to practice what you preach right? So right off the bat, there was a reassuring aura about Dr. Zhu and again, the bright genuine smile. Heading to see anyone regarding your teeth can be nerve-racking, but Dr. Zhu and his staff did everything in their power to ensure I felt at ease and understood the entire process of what would happen and what I needed. Nothing felt pushy or rushed. I felt like they all really cared about my well being and wanted to take the time to understand where I was coming from. People too often brush off the importance of the health of their teeth, and that's one of the biggest mistakes anyone could make. I would highly recommend going to see Dr. Zhu. I save my 5 star reviews generally, but Dr. Zhu and his staff are well deserving of the stars. Thanks guys!
