Your Dental Care Questions, Answered
Welcome to the Gateway Family Dentistry blog. We started this so we could answer the questions we hear most — without you having to wait for your next visit. Here's a first batch of the ones that come up at almost every appointment.
How often should I really brush my teeth?
Twice a day, for two full minutes each time. Once in the morning, once before bed. Brushing before bed matters most because it clears the plaque and bacteria that built up over the day. A quick brush between meals is a nice bonus, but the twice-a-day rule is the one to lock in. Playing your favorite song is a surprisingly good two-minute timer.
What's the best way to floss without hurting my gums?
Gently. Slide the floss between your teeth with a back-and-forth motion, curve it into a "C" shape around each tooth, and move it up and down. Don't snap it — that's what causes the soreness. If your gums bleed a little when you start flossing regularly, it usually settles down within about a week as the gums get healthier.
Do electric toothbrushes really work better than manual ones?
Both work when used correctly. Electric brushes make it easier to be consistent — the motion is steady and most have a built-in two-minute timer. They're especially helpful for kids and anyone whose hands tire out. That said, the best toothbrush is the one you'll actually use well, twice a day.
What foods are actually good or bad for my teeth?
Crunchy, water-rich foods like apples, carrots, and celery help clean your teeth and trigger saliva, which protects enamel. Dairy — cheese, yogurt, milk — provides calcium that strengthens enamel. On the other side, sticky candies, sugary snacks, and acidic drinks like soda wear down enamel and feed cavity-causing bacteria. You don't have to give up the treats you love, just balance them.
How does sugar damage my teeth, and are natural sweeteners safer?
When you eat sugar, bacteria in your mouth feed on it and produce acids that attack enamel. Over time, that's how cavities form. Natural sweeteners like honey, agave, and maple syrup break down into sugars too, so they're not really a free pass. Moderation matters more than which sweetener you pick.
Is whitening toothpaste safe for everyday use?
For most people, yes. Whitening toothpastes work by gently lifting surface stains. Some formulas are more abrasive than others, so look for one that's earned the ADA seal or that we've recommended. If you notice sensitivity, or you're hoping for more dramatic results than a toothpaste can deliver, ask us at your next visit — there are stronger options that are still safe.
Why do my teeth feel sensitive, and how can I fix it?
Sensitivity usually means enamel has worn down or your gums have receded, exposing the softer layer underneath. Hot, cold, or sweet foods reach the nerve more easily. A sensitivity-specific toothpaste, a softer brushing touch, and regular cleanings help. If it sticks around or gets worse, let us know — there are in-office treatments that quickly strengthen the area.
What's the difference between cavities, plaque, and tartar?
Plaque is the soft, sticky bacterial film that forms on your teeth every day. If brushing and flossing don't clear it, it hardens into tartar (also called calculus), which only a professional cleaning can remove. Cavities are actual holes in a tooth caused by the acid plaque bacteria produce. Daily brushing and flossing keep plaque in check; regular cleanings handle anything that gets past that.
