Everybody likes to have an attractive smile, everybody goes to the dentist, everybody uses the Internet. So why, in a world full of online chatter about medicine, wellness, drugs, nutrition, health care, yada yada . . . why do we see so few Internet conversations about dentistry?

There are some blogs out there, most of which seem to be about how to run a dental practice, attract patients and other things you don’t care about. But here are a few worth checking out:

Ask Dr. Spindel is a rapid-fire Q&A by Larry Spindel, a New York dentist. He has been blogging since 2005, and he doesn’t waste your time. His simple, fast-response format is possibly not as in-depth as you might like if you’re searching for information about something major like, say, dental implants. But if you’re wondering how other dentists or patients feel about the many small issues that come up at the dentist’s office — night guards, nitrous oxide, onlays, inlays, fluoridation, X-rays . . . take a look.

Bright Now is a commercial blog: It’s marketing the nationwide chain of Smile Brands dental offices. But they’ve got some good ideas, and here’s a recent eye-catcher for the hard-working young multi-tasker: Three quick workouts you can do while putting in the recommended four minutes a day of brushing: squats, lunges and calf raises. Seriously, why not?

And then there’s Mouthing Off, the blog of the American Student Dental Association — yes, students, which means you not only get an inquiring-mind point of view, you also hear from people who have been patients longer than they’ve been training to be a dentist.

From a recent post: “I constantly hear a specific professor yell out, ‘I can’t believe I see so many of you future dentists chewing gum!’ Chewing gum has been proven to increase brain function and overall cognitive thinking as well as suppress appetite. Now, there is an even better reason why we should all be chewing it. Research has been conducted and published in PLOS One that states that chewing gum can remove almost as much intra-oral bacteria as brushing your teeth twice a day and flossing regularly. . . . The gum does have to be sugarless or contain artificial sweeteners to work.”
