Answers from our dentists
Prevention & everyday care
Almost every cavity we treat could have been prevented — which is good news, because prevention is mostly a handful of simple, daily things done consistently. This section is the practical playbook: how to actually keep your child's teeth healthy between visits.
We answer the everyday questions parents ask most: how often your child really needs a checkup, how to help a young child brush and floss well, how much fluoride is right at each age, and whether sealants and treatments like silver diamine fluoride are worth it (usually, yes). We also tackle the ones that cause the most worry or confusion — are dental x-rays safe, which foods and drinks are the real cavity culprits, and what to do about thumb-sucking, pacifiers, teeth-grinding, and sports mouthguards.
None of it is complicated, and none of it needs to be a battle. The goal is a routine that fits your family and quietly protects your child's smile for years. If you want help tailoring any of this to your child — their cavity risk, their habits, their diet — just ask at a visit or call us at (201) 345-3637.
- How often should my child see the dentist? Most children should see the dentist every six months for a checkup and cleaning. Some — those more prone to cavities or with special dental needs — benefit from more frequent visits. We'll set the right schedule for your child at their exam and keep you on track. Read the answer
- Are dental x-rays safe for children? Does my child need them? Yes, dental x-rays are safe for children. Modern digital x-rays use a very low dose of radiation and let us see problems hidden between teeth or below the gumline that an exam alone can't catch. We take them only when needed — typically every six to twelve months depending on your child's cavity risk. Read the answer
- What is silver diamine fluoride (SDF)? Silver diamine fluoride (SDF) is a liquid we brush onto a cavity to stop it from growing — no drilling, no needles. It's a great option for young or anxious children. The one trade-off: it turns the treated spot of decay dark, which is why it's often used on back teeth. Read the answer
- Are dental sealants worth it for kids? Yes — sealants are one of the best-value ways to prevent cavities. A sealant is a thin protective coating painted onto the grooved chewing surfaces of the back teeth, where most childhood cavities start. It's quick, painless, and can prevent the majority of cavities in those teeth. Read the answer
- Is fluoride safe for my child? How much is right? Yes, fluoride is safe and highly effective at preventing cavities when used in the right amount. Use a rice-grain-sized smear of fluoride toothpaste for children under three, and a pea-sized amount for ages three to six. Supervise brushing so young children spit rather than swallow. Read the answer
- How do I help my child brush and floss well? Brush twice a day for two minutes with the right amount of fluoride toothpaste, and help or supervise until about age seven or eight — younger children don't have the coordination to do it well alone. Start flossing once any two teeth touch. Make it routine, and make it fun. Read the answer
- Which foods and drinks cause cavities in kids? Sugary and starchy foods feed cavity-causing bacteria — but how often and how long your child eats them matters even more than how much. Sticky candies, juice, soda, and constant snacking are the biggest culprits. Water and tooth-friendly snacks between meals protect teeth. Read the answer
- Is thumb-sucking bad for my child's teeth? Thumb-sucking is normal and harmless in babies and toddlers. It only becomes a concern if it continues past about age four, or once the permanent teeth start coming in — prolonged, vigorous sucking can affect how the teeth and bite develop. Most children stop on their own. Read the answer
- How do I break my child's pacifier habit? Aim to wean off the pacifier by around age two to three, before it can affect the developing bite. Go gradually — limit it to naps and bedtime first, then phase it out with praise, a "goodbye" ritual, or a small reward. Comfort and consistency work better than cold-turkey stress. Read the answer
- Does my child grind their teeth at night — is it a problem? Nighttime teeth grinding is very common in children and most often harmless — many grow out of it with no lasting effect. It's worth mentioning at a checkup so we can look for wear. We rarely need a nightguard for young kids, but we'll tell you if your child's grinding needs attention. Read the answer
- Do kids need mouthguards for sports? Yes — any child playing a contact or high-impact sport should wear a mouthguard. It protects against chipped or knocked-out teeth and cushions blows to the jaw. A custom-fitted mouthguard from your dentist offers the best protection and comfort, which means kids are more likely to wear it. Read the answer

- Sports Drinks and Juice: The Hidden Cavity Risk Sports drinks and juice hit teeth with a double blow: sugar for the bacteria and acid that softens enamel directly — even sugar-free versions keep the acid. Worse, both are sipped for an hour, restarting the attack with every swallow. For nearly every kid activity under an hour, water wins outright.Prevention & Everyday Care Say Cheez
- Straw, Sippy, or Open Cup: Which Is Best for Teeth? For teeth and oral development, the ranking is clear: open cup first, straw cup a close second, valved sippy cup last — it is essentially a bottle in costume. But the contents rule outranks the cup rule: milk with meals, water everywhere else, in any vessel.Prevention & Everyday Care Say Cheez
- Does Xylitol Really Help Kids' Teeth? Yes, with honest caveats: xylitol is a plant-based sweetener cavity bacteria can't digest — regular exposure reduces the bacteria and their acid, and evidence supports it as a helpful add-on, not a replacement for fluoride and brushing. Frequency is the trick, and it's seriously toxic to dogs.Prevention & Everyday Care Say Cheez
- Are Water Flossers Good for Kids? Water flossers are genuinely useful for kids — especially with braces, where they flush debris string can't easily reach — and they turn floss refusers into willing participants. The honest caveat: they don't scrape sticky plaque off tooth sides the way string floss does. Supplement, not substitute.Prevention & Everyday Care Say Cheez
- What Age Should Kids Get an Electric Toothbrush? Around age three — once basic brushing habits exist and your child can handle the buzz — is the right time to introduce an electric toothbrush, always with adult supervision. Electric brushes remove plaque more effectively than manual ones and make a despised chore feel like a gadget.Prevention & Everyday Care Say Cheez
- Choosing Your Baby's First Toothbrush and Toothpaste Before teeth: a damp washcloth or silicone finger brush once a day. From the first tooth: a soft, small-headed infant toothbrush and a rice-grain smear of fluoride toothpaste, twice daily. Lay baby back in your lap to brush — position, not product, is what makes infant brushing work.Prevention & Everyday Care Say Cheez
- Medicines That Raise a Child's Cavity Risk A medicine can raise cavity risk by reducing saliva, containing sugar, being acidic, sticking to teeth, or requiring frequent and nighttime doses. That does not mean the medicine should be stopped.Prevention & Everyday Care Say Cheez
- How to Choose a Toddler Toothpaste The formula is short: fluoride toothpaste from the very first tooth, a rice-grain smear until age three, then a pea. Pick a mild flavor your toddler tolerates, look for the ADA Seal of Acceptance, and ignore most of the rest of the label — amount and consistency matter far more than brand.Prevention & Everyday Care Say Cheez
- Are Gummy Vitamins Bad for Teeth? Unfortunately, yes — gummy vitamins combine three cavity ingredients: sugar, stickiness that lodges in molar grooves, and often citric acid that softens enamel. Even sugar-free versions bring the acid. Give them with a meal rather than at bedtime, rinse after, or switch to chewable or liquid forms.Prevention & Everyday Care Say Cheez
- Fluoride-Free Toothpaste: Does Hydroxyapatite Work? Hydroxyapatite — the mineral teeth are made of — is the most credible fluoride-free ingredient, and there's real evidence it helps enamel reharden. But it does not protect teeth quite the way fluoride does. For fluoride-avoiding families, hydroxyapatite plus excellent habits is the strongest plan B.Prevention & Everyday Care Say Cheez
- Smart Lunchbox Snacks for Healthy Teeth The lunchbox rules that protect teeth: cheese, nuts, crunchy produce, and plain yogurt are the all-stars; crackers, dried fruit, gummies, and juice are the cavity crew — even the organic ones. Pack water, keep sweets attached to lunch rather than scattered, and let crunchy foods do the cleanup.Prevention & Everyday Care Say Cheez
