October is National Dental Hygiene Month
Five practical oral hygiene habits for Jacksonville patients: gentle brushing, cleaning between teeth, fluoride toothpaste, and regular dental visits.
5 Simple Habits for a Lifetime of Dental Health
Master the Two-Minute Drill
Brush twice a day with fluoride toothpaste. Replace your toothbrush (or electric head) every 3-4 months. Frayed bristles don't clean—they just move bacteria around.
Floss Like a Boss
Brushing only cleans 60% of your teeth. Use floss or a water flosser daily to hit the hidden spots where cavities start.
The Power of the Rinse
Antibacterial mouthwash reaches your cheeks and tongue, killing the germs that brushing misses and keeping your breath fresh longer.
Eat for Your Enamel
Fuel up on calcium-rich foods and avoid "grazing." Constant snacking keeps your mouth acidic; give your saliva time to naturally protect your teeth.
Partner with the Pros
Professional cleanings remove tartar that home brushing can't. Regular exams catch small issues before they become big, expensive ones.
Fluoride Toothpaste and Jacksonville’s Water: Benefits, Safety, and Common Questions
How fluoride toothpaste protects teeth, how Jacksonville’s naturally occurring water fluoride fits into prevention, and when to discuss your individual needs.
Fluoride toothpaste helps prevent cavities by strengthening enamel and supporting the repair of early mineral loss. Brushing twice daily with fluoride toothpaste is recommended for children and adults, with small, age-appropriate amounts for young children. American Dental Association’s fluoride guidance
Here in Jacksonville, patients often have another question: does our drinking water already contain fluoride? For residents served by JEA, the answer is yes—it occurs naturally.
Understanding your toothpaste, drinking water, and individual cavity risk can help you make informed choices about daily dental care.
What is fluoride, and why is it in toothpaste?
Fluoride is a mineral that occurs naturally in rocks, soil, and water. It is included in many toothpastes because it helps protect teeth against decay. National Institute of Dental and Craniofacial Research
Bacteria in dental plaque use sugars from food and drinks to produce acids. Those acids remove minerals from enamel, the protective outer surface of your teeth. Repeated acid attacks can eventually lead to cavities.
Fluoride helps enamel regain minerals through a process called remineralization. It also makes teeth more resistant to future acid attacks. Early decay may be stopped or reversed before a cavity forms, but toothpaste cannot rebuild tooth structure once a hole has developed. NIDCR’s explanation of the tooth decay process
Does Jacksonville’s drinking water naturally contain fluoride?
Yes. Jacksonville residents served by JEA receive drinking water containing naturally occurring fluoride from the Floridan aquifer. JEA states that it does not—and has never—added fluoride to its drinking water. JEA’s water constituent information
Groundwater picks up minerals as it moves through underground formations. This means fluoride can be present in drinking water without being added during treatment.
The concentration can vary depending on the water system. Consult JEA’s water quality reports for reported testing results rather than assuming every Jacksonville household receives the same amount.
If your home uses a private well or another utility, check that source separately. JEA’s information applies to its own water supply.
Do I still need fluoride toothpaste if my water contains fluoride?
Yes. Drinking water containing fluoride does not replace brushing with fluoride toothpaste. Toothpaste delivers fluoride directly to the tooth surface, helping protect enamel where decay begins. The ADA recommends fluoride toothpaste even when drinking water contains fluoride. ADA’s fluoride guidance
Is fluoride toothpaste safe?
Fluoride toothpaste is recommended for routine cavity prevention when used as directed. Spit it out after brushing, and supervise young children to help them avoid swallowing it. ADA’s brushing recommendations
For children, one concern is dental fluorosis, an enamel change that can develop when they repeatedly consume too much fluoride while teeth are forming beneath the gums. Fluoride intake from all sources matters—not just toothpaste.
Mild fluorosis usually appears as faint white lines or streaks on teeth. Using the appropriate amount of toothpaste and supervising brushing helps reduce the risk. ADA’s fluorosis guidance
What about fluoride and other health concerns?
Fluoride research requires attention to the amount, source, and duration of exposure.
The National Toxicology Program concluded with moderate confidence that higher fluoride exposure, such as drinking water containing more than 1.5 milligrams per liter, is associated with lower IQ in children. An association does not establish cause and effect.
Its subsequent analysis also found associations at lower exposures in some studies, while noting uncertainty when examining drinking-water concentrations below 1.5 milligrams per liter. There were insufficient data to determine whether drinking water at 0.7 milligrams per liter affects children’s IQ.
These findings deserve careful discussion. They do not establish that brushing with fluoride toothpaste as directed causes those outcomes, nor do they resolve every question about lower exposures. National Toxicology Program’s fluoride assessment
How much fluoride toothpaste should children use?
Begin brushing with fluoride toothpaste when the first tooth appears.
Younger than age 3: Use a smear no larger than a grain of rice.
Ages 3–6: Use no more than a pea-sized amount.
Supervise brushing: Help children brush thoroughly and teach them to spit out toothpaste.
Keep toothpaste out of reach between brushings. Children younger than 6 should not use fluoride mouthwash unless a dentist recommends it. ADA’s recommendations for children
Before starting a fluoride supplement, discuss your child’s drinking-water source and other fluoride exposure with their dentist or pediatrician. Naturally occurring fluoride counts toward total intake, too. ADA’s fluorosis prevention guidance
How do you choose the right toothpaste?
Start with a fluoride toothpaste intended for cavity prevention. Products bearing the ADA Seal of Acceptance offer another way to identify evaluated dental-care products. ADA’s fluoride and product guidance
Your other symptoms matter as well. Tooth sensitivity, recurring cavities, or persistent mouth dryness are useful reasons to discuss your home-care routine with a dentist.
For example, dry mouth can increase cavity risk because saliva helps protect teeth. Choosing toothpaste should be part of a plan that also considers why your mouth is dry, including medications or medical conditions.
Common questions about fluoride toothpaste
Do adults benefit from fluoride toothpaste?
Yes. Adults can develop cavities, including decay on exposed tooth roots. Brushing twice daily with fluoride toothpaste remains part of preventive care throughout adulthood. NIDCR’s oral hygiene guidance
Does fluoride toothpaste replace flossing?
No. Brushing and cleaning between teeth address different surfaces. Fluoride toothpaste supports cavity prevention, while daily interdental cleaning helps remove plaque from areas a toothbrush cannot adequately reach. NIDCR’s oral hygiene guidance
Can fluoride toothpaste repair a cavity?
It can help repair early mineral loss before a hole forms. An established cavity represents permanent damage that needs dental evaluation and usually restorative treatment. NIDCR’s tooth decay guidance
Do I need additional fluoride if I have dry mouth?
Possibly. Additional topical fluoride may be appropriate when dry mouth raises your decay risk. The recommendation should follow an assessment of your symptoms, medical history, and dental findings. Our dry-mouth evaluation and treatment page explains that approach.

Best Foods for Healthy Teeth
Is what you eat good for your teeth? Find out which foods help promote healthy teeth and gums.
A varied diet, water as your usual drink, and fewer frequent sugary snacks can support dental health. Food choices work alongside brushing, cleaning between teeth, and dental examinations; no food or supplement treats a cavity or replaces care for gum disease.
Which foods support healthy teeth and gums?
Build meals around a variety of vegetables, fruit, protein foods, and sources of calcium. Whole fruit usually makes a more useful snack than repeatedly sipping juice. Plain dairy foods or suitable fortified alternatives can contribute calcium; check labels for added sugar. Choose foods that fit your medical needs, allergies, and ability to chew.
Why does how often I snack matter?
Repeated exposure to sugary drinks and snacks gives the mouth less time between acid challenges. Consider the pattern across your day, including sweetened coffee, sports drinks, juice, and foods that linger around teeth. Water with meals and between meals is a practical starting point. Read our sparkling-water guide if flavored or carbonated drinks are part of your routine.
Can low vitamin C cause bleeding gums?
Severe vitamin C deficiency can affect gum health, but bleeding gums have several possible causes, including plaque-related inflammation. Do not assume that a supplement will solve the problem. A limited diet is worth discussing with your medical clinician; persistent bleeding also deserves a dental examination. Peppers, kiwifruit, broccoli, and strawberries are examples of foods containing vitamin C.
Should I take vitamins for my teeth?
Discuss supplements with your clinician if you have a deficiency, restricted diet, medical condition, or difficulty eating. Taking extra vitamins without identifying a need is not a substitute for dental treatment. Bring a list of supplements and medications to your appointment, especially if you receive care for complex medical needs.
What else helps prevent cavities?
Brush with fluoride toothpaste and clean between teeth each day. Our toothpaste guide explains how to compare products. Dry mouth changes cavity risk, so tell us if eating or swallowing feels dry; see our dry-mouth information.

New York Times: The Value of Sealants
In an article published in the New York Times, "a review concluded that sealants are effective in reducing cavities for at least four years after each application." and that "when your dentist offers sealants for your children, it’s not an upsell, but a deal you should accept."
We agree! We routinely recommend that children have sealants placed on permanent teeth when appropriate. Moreover, it is important that sealants are done properly to ensure that they will last a long time.
