Crown Lengthening
Crown lengthening is a specialized dental procedure designed to expose more of a tooth’s surface by reshaping gum tissue and bone. Whether for functional or cosmetic reasons, this treatment enhances oral health, restores damaged teeth, and improves smile aesthetics.

What is Crown Lengthening?
Crown lengthening is a surgical procedure that reshapes the gum tissue and bone to expose more of the tooth’s surface. This treatment is commonly performed for restorative or cosmetic purposes, such as preparing a tooth for a dental crown or improving a “gummy smile.” By adjusting the gum and bone levels, crown lengthening enhances both function and aesthetics.

Reasons for Crown Lengthening
Crown lengthening may be recommended for various reasons, including:
- Restorative Needs – When a tooth is broken or has deep decay below the gum line, crown lengthening helps expose more of the tooth for proper restoration.
- Cosmetic Enhancement – Patients with excessive gum tissue or a “gummy smile” can benefit from crown lengthening to achieve a more balanced appearance.
- Better Oral Health – Reducing excessive gum tissue can lower the risk of periodontal disease by making oral hygiene easier.

What Patients Are Saying
Dr. Yousefi was fantastic. She was calm, funny, and capable. She immediately put me at ease (I was pretty anxious). I have never been numbed up so quickly and near painlessly – and the rest of the procedure was then painless, too. She and her team gave clear directions as to what to do for the next 24 hours and beyond, what to eat, how to care for the flipper temporary tooth, and answered all my questions. The staff called me the next business day to follow up and answered more questions that I had come up with by then. Highly recommend.

Sara is an excellent dental hygienist and really cares about her patients. She is very good at providing a regimen to help my gums. Dr. Eskow did my gum revision surgery years ago and he’s the best. I recently needed some more work done around the come on 12 and Dr. Eskow handled it beautifully, and his assistant Emily was great.. And the staff at the front desk always makes it a pleasant visit.

My family and I have been patients for maybe 10-15 years! After trying a bunch of different dentists, we found Dr. Yousefi and have been happy with her team and their services ever since. She has helped us with minor issues as well as major long-term care, including a broken tooth and a few implants. The service has always been amazing, and we are very happy with the quality and expertise here. The new, amazing facilities with super convenient parking are just the cherry on top!

Two weeks post-surgery and I couldn’t recommend this office more. Both doctors are wonderful and clearly very experienced with a patient-first mindset. The office followed up frequently after my surgery to ensure I was recovering well and to answer any questions. After two weeks, I have no pain from the surgery and the gums have already healed up. If you are in need of any dental surgery work, I would 100% recommend this office!

I’ve been a patient of Dr. Raha Yousefi for over two years, and she is truly one of the best. From day one, her professionalism and genuine care for her patients were evident. Dr. Yousefi’s expertise in dentistry is outstanding, and she takes the time to explain every step of the treatment, ensuring I feel comfortable and informed. Her warm and compassionate personality makes every visit a pleasant experience, and it’s clear she deeply values her patients. The staff at her practice is equally amazing—always friendly, professional, and welcoming. I highly recommend Dr. Yousefi to anyone seeking a dentist who combines professional excellence with heartfelt care.
