Welcome to the Practice

We work closely as a team with your referring dentist, but a referral by a dentist is not required to become a new patient. We welcome referrals from patients and friends of the practice. If you are in need of a general or restorative dentist, we can provide you with the names of some of the excellent dentists we work with.

We communicate with you and your dentist, ensuring that your clinical, periodontal, and administrative needs are met as efficiently and smoothly as possible.

Our goal is to make you feel comfortable and relaxed. We are here to listen to you and to help provide solutions leading to your better health. Periodontal treatment is a partnership between your periodontist, your dentist, any other treatment providers, and you. If you are anxious about receiving care, we have a variety of sedation options available to make your treatment as easy as possible.

Our goal is to help our patients. We understand that some treatment, particularly in advanced cases, can be a significant expense. If your treatment involves multiple procedures, they can usually be spaced out over time to accommodate your schedule and personal finances.

We are preferred providers with Delta Dental PPO Premier. If you’re a member of another PPO (for instance, Aetna, BlueCross, Cigna, Delta Dental, Guardian, Metlife), it’s likely that your insurance will still cover a good portion of your treatment. We will submit all necessary paperwork on your behalf.

If your insurance plan is an HMO or DPO, it will exclusively cover services by providers under that plan. Call the number on your insurance card for providers. We do not accept Denti-Cal or Medi-Cal. If you are seeking a Denti-Cal provider, please click here.


Competent, friendly professional services. Dr Oh explained everything clearly and thoroughly ahead of time and during the procedure. By the way, there was zero waiting time, which is nice.


I cannot be happy enough with the services of Dr. Oh and team at Alameda Periodontics. Dr. Oh and team are very detailed oriented and strive for perfection in their care. I also sense a high form of ethics with Dr. Oh and team. For instance, Dr. Oh quoted me one price to take care of my dental need. She later, after performing the treatment found that I didn’t need as much care as previously stated. She went on to say that she would charge less than previously required. I can’t say that many dentist value their relationship with their patients with a strong sense of ethics as Dr. Oh and team provides. I truly can say that I am very comfortable with Dr. Oh and team, and the fact that I don’t have to worry whether my treatment will go well and that the cost is fairly calculated. I highly recommend Alameda Periodontics to anyone who want to focus on healing, while not worrying whether the treatment will go well and the related cost.
