Keeping your child's teeth healthy takes more than brushing twice a day. The water they drink, their snacking habits, and the preventive treatments they receive can all affect their risk of cavities.
For families on Oahu and Maui, there's an important detail that often gets overlooked: the municipal water suppliers serving many local households do not add fluoride to their drinking water.
That makes it especially useful to understand your child's fluoride exposure and whether additional preventive care may be appropriate.
At Pedodontic Associates, we help Hawaii families protect growing smiles through regular dental exams, cleanings, fluoride treatments, sealants, and practical home-care guidance.
Here's where we recommend starting.
1. Know What’s in Your Family’s Drinking Water
Fluoride helps protect tooth enamel against decay. Children can get fluoride from toothpaste, professional treatments, and some drinking-water sources.
But not all water supplies are the same.
The Honolulu Board of Water Supply confirms that it does not add fluoride to Oahu's municipal water supply. The Maui Department of Water Supply also states that it does not add fluoride to the water it supplies.
Some water systems, including certain military supplies, are different. Naturally occurring fluoride levels can also vary.
What should Hawaii parents do?
Find out which water system supplies your home. If you're unsure about its fluoride content, check with your water provider and share that information at your child's next dental visit.
We can help you review whether your child's current fluoride toothpaste routine is appropriate and whether professional fluoride treatments may be beneficial.
Don't start fluoride supplements without professional guidance.
2. Make Daily Habits Work for Island Life
Between school, beach trips, sports, and family activities, children don't always follow a predictable schedule.
The most useful preventive habits are the ones your family can maintain even on busy days.
Brush twice daily with fluoride toothpaste. Children younger than 3 should use a rice-grain-sized smear. For ages 3 to 6, use a pea-sized amount. Younger children need hands-on help with brushing, and flossing should begin when adjacent teeth touch.
If you're unsure about the correct amount, our fluoride toothpaste guide for kids explains the recommendations in more detail.
Choose water between meals and activities. Juice, sweetened drinks, and sports drinks expose teeth to sugar. Frequent sipping throughout an afternoon can increase cavity risk.
Hawaii treats such as shave ice can still be part of family life. The important distinction is an occasional treat versus repeated sugar exposure throughout the day.
Keep bedtime brushing consistent. Even when your child comes home tired after a long day, brushing before sleep remains an important part of their routine.
3. Use Dental Checkups to Prevent Problems, Not Just Find Cavities
The American Academy of Pediatric Dentistry recommends establishing a dental home by a child's first birthday.
After that, checkups are commonly recommended every six months, although the appropriate schedule depends on the child's needs and cavity risk.
At our Oahu and Maui offices, preventive visits give us an opportunity to examine developing teeth, identify early concerns, provide professional cleanings, and discuss your child's home-care habits.
Depending on the examination, we may also recommend:
Fluoride treatments: Professional applications that help protect enamel against decay.
Dental sealants: Thin protective coatings for the chewing surfaces of back teeth. These can be especially useful as adult molars begin erupting, commonly around ages 6 and 12.
The CDC reports that sealants can prevent approximately 80% of cavities in back teeth during the first two years after application.
Not every child needs the same treatments. We'll explain our findings and help you understand the recommendations for your child.

4. Ask These Questions at Your Child’s Next Visit
A dental checkup should leave you knowing what to do next.
Consider asking:
- Is my child at increased risk for cavities? Understanding their risk can help guide preventive care.
- Is their fluoride exposure appropriate? This is particularly useful when your household uses municipal, bottled, filtered, or well water.
- Would dental sealants help protect their molars? The answer depends on which teeth have erupted and their condition.
- What is one home-care habit we should improve? A specific recommendation is often easier to follow than a long list of instructions.
Our goal is to help your family leave with a practical plan that fits your child's needs.
