About SF Implants and Perio | Dr Terry Im and Associates

SF Implants and Perio | Dr Terry Im and Associates is a dental practice on Sutter Street in the Union Square area of San Francisco, California. Periodontics is the specialty focused on the gums and the bone supporting the teeth, handling more advanced gum disease, related surgical treatment, and — in many practices — dental implant placement, which sits naturally alongside that training.

A first appointment at a new practice typically covers a full examination, a review of your dental and medical history, and a professional cleaning, with X-rays if you do not have recent ones. It is also a reasonable time to raise any longer-term concerns, cosmetic or otherwise, so they can be factored into a plan going forward.

Day-to-day oral health still comes down to the basics between visits — brushing twice daily with fluoride toothpaste, cleaning between the teeth, and limiting how often sugary food and drink appear through the day matters more than the total amount eaten at once. Regular professional care is what catches whatever those habits do not.

Digital X-rays are a routine part of dental care because they show what a visual exam alone cannot — decay forming between teeth, bone loss below the gumline, and how developing adult teeth are positioned in children. They use a low radiation dose and are taken on a schedule matched to individual risk rather than at every single visit.

Left untreated, small dental problems tend not to stay small. A minor cavity that would have been a straightforward filling can progress to needing root canal treatment and a crown, and early gum inflammation that would have reversed with a good cleaning can progress toward bone loss around the teeth. Catching things early is generally the difference in both effort and cost.

Continuity matters in dental care — seeing the same practice over time means your history, X-rays, and any patterns in your oral health are already on file, rather than starting from scratch at each visit. That familiarity is part of what a regular dental home offers beyond any single appointment. This page has the practice's contact details and full service list.

What is gum recession and can it be treated?
Recession is when gum tissue pulls back and exposes more of the tooth root, often from aggressive brushing, gum disease, or grinding. Grafting procedures can cover exposed roots, though how well that works depends on the extent of the recession.
Can a periodontist save a loose tooth?
Sometimes. If the looseness comes from bone loss around the tooth, deep cleaning and periodontal treatment can stabilise it, though the outcome depends on how much support has already been lost.
Is it normal for teeth to be sensitive to cold?
Mild, brief sensitivity is common and often relates to exposed root surfaces or worn enamel. Sensitivity that lingers after the cold is removed is more significant and worth having examined, as it can indicate the nerve is involved.

Dr.Gunstream's office is extremely clean. Her staff very attentive and courteous. Doctor Gunstream is a top surgeon, I felt confident in her hands.

Dr. Gunstream did a very good job with my gum graft. Quick recovery, very good treatment, and solving all my questions. Also she was conservative on the treatment, which is always appreciated

I don’t say this lightly: Dr. Gunstream might be the worst physician I’ve ever had. In my experience, Dr. Gunstream was a remarkably untrustworthy and incompetent doctor, who was matched in quality by her office's front desk and hygienist. I came to Dr. Gunstream’s office experiencing new pain and abnormal changes. She concluded my condition required no action. Wondering if she might’ve missed something, I returned soon after; during which she determined any issue was not within her purview. Upon Gunstream’s suggestion, I booked my next cleaning with her office, in anticipation that she would check my status and update my notes, as was routine with previous providers. During that appointment, I was frustrated with the front desk to learn it was booked on Gunstream’s off-day. Doubly surprising was going home with a swollen lip from the heavy-handed hygienist tugging so hard during that needlessly miserable cleaning. I never scheduled another. Months later, I called Dr. Gunstream’s office and booked a 6-month evaluation. Within minutes, I received a callback from her office to cancel the appointment I’d just made. The reason cited was that Gunstream doesn’t see patients sooner than one year intervals for evaluations. This was odd, and completely counter to my experience with other providers. Though confused, I reluctantly accepted the situation. Something still felt off, so months later I booked another eval appointment. Again, the same exact thing happened. I was instantly called back by her front desk to cancel said appointment. By this point, what was a frustrating situation had become legitimately distressing. Eventually, I insisted on speaking with Gunstream directly to understand why she was denying me care. She curtly stated that she wasn’t, and agreed to do the eval - which again resulted in no recommendations. I finally sought a second and third opinion from other offices within her specialty, both of whose conclusions directly conflicted with Gunstream's. In hindsight, I should’ve gone elsewhere sooner. The time, energy, and money wasted on Dr. Gunstream’s office was truly regrettable. I'll never know what was really going on, but whether or not Gunstream had some personal issue with me, nothing justifies the blatant dishonesty and unprofessionalism.

Everyone in the office is friendly as well as professional, efficient and patient - with clear communication and answers to any questions. Highly recommend.

I had a gum graft with another surgeoun, and it was miserable. The care and work of Dr. Gunstream and Henry made both my experience and my healing SOOO much better and less painful than my last experience!
