I’m Dr. Christopher Yoo, a practicing general dentist at Karis Family Dental in Whittier, California. I’ve been seeing patients in this community for 10 years. This site is a side project — an honest, plain-English review of the dental products I actually recommend to those patients, written by someone who has to look them in the eye the next time they come in for a cleaning.
If you came here looking for the “best electric toothbrush of 2026” and you’re trying to figure out whether the reviewer is a real person who knows what they’re talking about — yes, I am, and below is the longer version of why you should trust the recommendations on this site.

I’m a general dentist. I’m not a periodontist, an orthodontist, or a specialist of any kind, and where the right answer for a patient lies in someone else’s domain — orthodontics, oral surgery, complex perio — I refer. That’s part of why this site exists.
Why I started this site
The honest version: I got tired of patients showing me articles on their phones from “best dental product” sites and asking whether they should buy what some affiliate writer had ranked first. Most of the time, the recommendations were lazy at best and dangerous at worst.
The category is flooded with content written by SEO generalists who don’t see patients, can’t read a clinical paper, and have never had to explain to a real person why their gums are bleeding or why their teeth are sensitive. A lot of that content ends up recommending products that aren’t great. Some of it recommends products I would actively tell a patient to avoid — DTC mail-order clear aligners, fad charcoal toothpastes that abrade enamel, mouthwashes with no meaningful evidence base, “miracle” oral probiotics with cavity-cure claims that don’t hold up.
I started this site to fill that gap from the dentist side. The products on it are products I personally use, recommend to patients chairside, or both. The products that aren’t on it are either ones I haven’t reviewed yet or ones I deliberately won’t recommend.
I make a small commission on some of the products linked here. I’m transparent about that — every post has an affiliate disclosure at the top, and the Affiliate Disclosure page covers the details. The affiliate model lets me write detailed long-form reviews and not charge readers for them. It does not influence which products I recommend. The first commitment is the one to the patients I see every week — they’ll know if anything on this site is dishonest, and they’d tell me.
Reviewing dental products is something I genuinely enjoy. In a typical week, I talk with dozens of patients about which toothbrush, floss, or whitening product they should pick — and I am constantly trying things myself, in my own bathroom, to see what is actually worth the money. The conversations I have at the chair were the seed of this site: friends, family, and patients kept asking, “Just tell me which one to buy.” So here it is, in writing, with the same straight answer I would give if you were in my chair.
I will admit this is a bit of a nerd hobby stacked on top of a day job. I read the toothbrush bristle-stiffness data sheets so you do not have to. I have spent embarrassingly long comparing whitening-strip peroxide percentages and contact times. The payoff for readers is that the reviews are written by someone who actually finds this stuff fun, and I think that comes through. The straight talk at the chair has always been my favorite part of dentistry — this site is just the written version of it.
Editorial standards
This is the most important section on the site. It’s also the moat. A product gets recommended here only if it meets all of the following:
1. I personally use it, or I routinely recommend it to patients in chair at Karis Family Dental. If it isn’t in my own bathroom or my own patients’ take-home bag, it doesn’t get a recommendation. No exceptions, regardless of affiliate commission rate.
2. It complements professional dental care — it doesn’t try to replace it. Products that help a patient maintain what their dentist treats are in. Products that try to substitute for the dentist are out. The clearest example is DTC clear aligners — see #3.
3. No direct-to-consumer clear aligners. Byte, SmileDirectClub (defunct anyway), Candid, AlignerCo, NewSmile, and every other mail-order aligner brand are excluded as a category. Orthodontic treatment is a clinical service that belongs under a licensed dentist’s or orthodontist’s direct supervision, with imaging, periodontal assessment, and in-person monitoring. I won’t review them, I won’t affiliate-link them, and if a reader asks about them my answer is to see a dentist or orthodontist in person. The 2024 Byte recall and the SmileDirectClub bankruptcy aren’t exceptions to this position — they’re confirmations.
4. No fad / wellness-grift dental products. Charcoal whitening powders, oil pulling oils marketed as cavity cures, “tooth gum” regrowth products, MLM-style oral probiotics with miracle claims. If the marketing leans harder on aesthetic-influencer language than on clinical evidence, it’s out.
5. I’ll call out products that don’t work — by name. A roundup with five products where one of them is a clearly-labeled “skip this one” is more useful than five thumbs-up. I review electric toothbrushes I don’t like. I name whitening brands I won’t recommend. The willingness to say no is half the credibility on this site.
These standards apply to every post on the site without exception.
What this site is not
It is not a clinical channel for my patients. If you’re already a patient at Karis Family Dental and you have a specific question about your treatment, your filling, or your last cleaning — please call the practice. I can’t and won’t address individual treatment questions over a blog post.
It is not personalized medical advice. The information here is general, written for the average reader. Your situation could be different in ways I can’t see. If you’re trying to decide whether to act on something you read here, talk to your own dentist.
It is not a complete review of every product on the market. The site launches with a deliberately narrow set of five product categories I personally stand behind (electric toothbrushes, Cocofloss-style flossing, TheraBreath-style mouthwash, Sensodyne-style sensitivity toothpaste, and whitening — specifically Crest 3D White Strips and Opalescence Go). The categories will grow over time, but only at the pace I can vet products carefully. This is intentional. Most affiliate sites are wide; this one is deep.

If you live in or near Whittier, California, and you’d like to be a patient at Karis Family Dental, you can find appointment information at karisfamilydental.com. I see general dentistry patients of all ages. The practice and this site are separate — Karis Family Dental is a clinical service, this site is editorial — but I’m the same person on both ends.
FAQ
Why isn’t every product on the site reviewed?
Because I won’t review a product I haven’t used myself or wouldn’t hand to a real patient. The site is intentionally narrow. I’d rather have 30 carefully written reviews of the products I genuinely stand behind than 300 surface-level reviews of everything in the category. Over time the universe will grow — into water flossers, retainer care, kids’ products, and more — but only at the pace I can vet products honestly.
How does the affiliate model work?
Some of the product links on this site are affiliate links. If you click one and end up buying the product, the retailer (often Amazon, sometimes the brand directly) pays me a small commission, at no additional cost to you. Commissions on the products I review here are typically in the 3–20% range depending on the program. Every post that contains affiliate links has a clear disclosure at the top of the page. I am required by FTC rules to disclose this, and I do, because that’s the right thing to do regardless of the rules.
Does the commission influence which products you recommend?
No. The editorial standards in the section above are the filter. I pass on plenty of higher-commission products that don’t meet those standards — including most DTC whitening brands, every DTC aligner, and a long list of products with unsupported clinical claims. I’d rather earn a smaller commission on a product I’d hand a patient than a bigger commission on something I wouldn’t.
Where can I see your full clinical credentials?
My California dental license is verifiable through the Dental Board of California license lookup [CONFIRM: link target] — search for “Christopher Yoo, DMD” or by license number 100322. My NPI is verifiable through the NPI Registry — 1730531666. Both of these are public registries; the dental board lookup also shows any disciplinary history (none, in my case).
Can I email you with a product question?
Yes, but with two honest caveats. First, I can’t give personalized clinical advice over email — that requires an exam, imaging, and a real patient relationship. Second, I read every reader email and try to respond, but I see patients full-time and the response speed depends on the week. Reader questions sometimes become the subject of new posts.
Are you on social media?
The site has a Pinterest presence — [CONFIRM: Pinterest URL] — where I share the same product picks and how-to content. There’s no YouTube channel and no on-camera video at launch. The writing carries the weight here, and I’d rather put the time into careful posts than into video I don’t have the bandwidth to produce well.
