Dental Practice Hero – Dr. Shalini Sethi

Why do you believe it is important to proactively diagnose periodontal disease?

Periodontal disease is extremely important to diagnose since it can have detrimental effects on your dental health and body. The gums and bone are the “basic foundation” for teeth. Periodontal disease can lead to bone loss, inflammation, bleeding, loose teeth, and an abscess. In turn, any one of these situations also has a systemic effect on your health.

I explain periodontal disease like this: Periodontitis is a “silent disease,” almost like heart disease. Many times, people don’t have symptoms and are unaware they have periodontal disease, and therefore, time goes go by without treatment. Then, one day a patient comes in with a severe abscess or pain and they need emergency treatment.


I emphasize the importance of regular checkups, periodontal screenings, x-rays, and hygiene visits with their general dentist. If periodontal issues are ignored, then you are at an increased risk of losing your teeth and replacement options can be quite expensive. I tell patients spend your money wisely! Try to save as many teeth as possible because you are better in the long run!

What obstacles do you face in getting patients to agree to treatment and how do you overcome them?

The biggest challenge I face as a periodontist is that patients tell me they don’t feel anything, and therefore, they don’t feel the need to fix it. It is a common statement amongst my patients, and they find treatment to be expensive. My response is that when your arteries are getting clogged, do you feel or know that is happening before you suddenly have a heart attack? They tend to ponder and realize what I am saying, and they inquire more. Showing them intraoral photos of their mouth and any visual representations are key. I also try to show photos of procedures that I have performed in the past so they can assess what their outcome would be.  I try to break their treatment down into phases, so they don’t get overwhelmed with long appointments and a huge financial constraint. Finances are also a big obstacle that we face and we have to find ways to work out a system so they can afford it.

How do you incorporate the Perio Protect Method® in your treatment protocols?

I started incorporating Perio Protect in my practice when I noticed that the gingival health in my patients was noticeably better than without it. I deliver these trays to my patients with 4-5mm pockets where there is persistent bleeding and inflammation and plaque, but where the patient does not require periodontal surgery. I also have patients who could not afford or are not candidates for surgery, such as cancer patients, etc. It is the least invasive method of maintaining my patients. It’s been a game changer for me with patients who are getting osseous surgery and they wear the trays during the healing phase. In those patients, I have noticed a reduction in plaque, bleeding, and the tissues are more firm, pink, and stippled. I believe that my surgery has an improved outcome compared to my cases without the trays. I also love getting feedback from my patients who really appreciate it!  They tell me, “My teeth are whiter, feel better, and my gums stopped bleeding.” I love it and my patients love it; we are both happy!
