• A lot of patients are worried that dental X-rays can cause cancer, but if you’re outside for an hour, you’re exposed to more radiation than you’d get from a full set of dental X-rays. What I worry about is that if I don’t take an X-ray, I might miss something serious. – Bryan Tervo, DDS
• When someone meets you for the first time, the first thing they notice is eyes. Second is teeth, and third is hair. But people spend way more money on their hair than their teeth. – Damian Dachowski, DMD, general dentist, Horsham, Pennsylvania

• If you want to reduce the bad bacteria in your mouth, you should be all over xylitol (a sugar substitute found in chewing gum). It changes the chemistry of your mouth. Six or seven pieces of xylitol gum every day will help keep cavities away. – Chris Kammer, DDS

• With any kind of mouth piercing, there’s a huge risk of infection if it’s not done in a really sterile environment. I’ve seen cases where we’ve had to cut out pieces of the tongue because the infection was so rampant. Even when things go well, virtually everyone I see with a tongue piercing has chipped front teeth. Don’t pierce your tongue. – Jay Grossman, DDS, cosmetic dentist, Brentwood, California

• When choosing a dentist, Check if the magazines in the waiting room are current. That shows attention to detail. – Michael Alkon, DMD
