Specialist care for your gums and the foundation of your smile, from a periodontist right here in our Mission Viejo office.
A periodontist is the dental specialist who focuses on the gums and bone that support your teeth, and on placing dental implants. Most dental offices refer this work out. At Vartanian Dental Group, periodontist Dr. Richard Lee provides advanced gum and implant care right here in Mission Viejo, so you get specialist treatment without being sent to a separate practice.
4.9 stars across 1,300+ Google reviews, and your gum care comes from a true specialist, not a referral across town.
Dr. Richard Lee, DMD earned his dental degree from Tufts University School of Dental Medicine, completed an in-depth implant training program at Loma Linda University, and returned to Tufts for a full post-graduate residency in periodontics, the specialty devoted to gum health and dental implants. His focus is on diagnosing problems early and giving you the tools to keep your gums healthy for the long term. He works alongside Dr. James Vartanian and the hygiene team patients regularly praise by name.
“I love that this office has all the specialties so I don’t have to shop around.”
The cost of periodontal treatment depends on the stage of disease and the procedures involved, from maintenance to grafting or surgery. After your evaluation, you receive a written treatment plan with the full cost, so there are no surprises.
Many PPO and HMO plans cover periodontal treatment, and we verify your benefits before treatment begins. For any balance, payment plans through CareCredit and Citi are available. See our financing options.

Treatment always begins conservatively. When gums respond to non-surgical care, that is where we stop. When more is needed, Dr. Lee provides advanced options in the same office.
For receding gums, a gum graft (gingival graft) restores the tissue that protects your tooth roots, reducing sensitivity and improving how your smile looks.
When gum disease or a missing tooth has caused bone loss, bone grafting rebuilds the foundation, often a key step before placing a dental implant.
In advanced cases, flap surgery allows Dr. Lee to clean deep below the gumline and reduce the pockets where bacteria collect, helping your gums reattach and heal.
As a periodontist with dedicated implant training, Dr. Lee places dental implants and handles the gum and bone work that complex implant and full arch cases often require.
You may see a periodontist on your own or because your dentist referred you. Dr. Lee provides specialist care for:
If your main concern is bleeding gums, early gum disease, or a deep cleaning, start with our gum disease treatmentpage, which covers diagnosis and non-surgical care. When a case needs specialist or surgical treatment, that is where Dr. Lee steps in.


Periodontal problems rarely stay isolated. Gum disease can threaten teeth, bone loss complicates implants, and surgery often needs restorative follow-up. When your periodontist, general dentist, and restorative team all work in one office, your care is coordinated instead of scattered across separate practices with separate records.
That is the advantage here: Dr. Lee’s specialist work connects directly with the rest of your treatment, from the cleaning and exam that catches a problem to the implant that follows surgery. You will find us on the first floor of Pacific Canyons Medical Center at 26302 La Paz Rd #203, just off the I-5 at the La Paz Road exit, with on-site parking. We care for patients from across the city, Rancho Mission Viejo, Lake Forest, Laguna Niguel, Rancho Santa Margarita, and Aliso Viejo.
Open Monday to Thursday 8 AM to 5 PM and Friday 8 AM to 3 PM.
