In the last half century, fluoride has become an effective weapon against tooth decay. The naturally occurring mineral helps strengthen enamel, the teeth's hard, protective cover.
Although it's safe for consumption overall, too much during early tooth development can lead to fluorosis, a brownish, mottled staining in enamel. To avoid it, a child's daily consumption of fluoride should optimally be kept at around 0.05-0.07 milligrams per kilogram of body weight, or an amount equal to one-tenth of a grain of salt per two pounds of weight.
The two main therapeutic fluoride sources have limits to help maintain this balance: utilities that fluoridate drinking water are required to add no more than 4 parts fluoride per million (ppm) of water; toothpaste manufacturers likewise only add a small amount of fluoride compared to clinical gels and pastes dentists apply to teeth for added decay protection.
But drinking water and toothpaste aren't the only sources of fluoride your child may encounter. Even if you have a non-fluoridated water supply, you should still keep a close watch on the following items that could contain fluoride, and discuss with us if you should take any action in regard to them.
Infant formula. The powdered form especially if mixed with fluoridated water can result in fluoride concentrations 100 to 200 times higher than breast or cow's milk. If there's a concern, use fluoride-free distilled or bottled spring water to mix formula.
Beverages. Many manufacturers use fluoridated water preparing a number of packaged beverages including sodas (two-thirds of those manufactured exceed .6 ppm), soft drinks and reconstituted fruit juices. You may need to limit your family's consumption of these kinds of beverages.
Certain foods. Processed foods like cereals, soups or containing fish or mechanically separated chicken can have high fluoride concentrations, especially if fluoridated water was used in their processing. When combined with other fluoride sources, their consumption could put children at higher risk for fluorosis.
Toothpaste. Although mentioned previously as a moderate fluoride source, you should still pay attention to how much your child uses. It doesn't take much: in fact, a full brush of toothpaste is too much, even for an adult. For an infant, you only need a smear on the end of the brush; as they grow older you can increase it but to no more than a pea-sized amount.

When Entertainment Tonight host Nancy O’Dell set out to teach her young daughter Ashby how to brush her teeth, she knew the surest path to success would be to make it fun for the toddler.
“The best thing with kids is you have to make everything a game,” Nancy recently said in an interview with Dear Doctor TV. She bought Ashby a timer in the shape of a tooth that ticks for two minutes — the recommended amount of time that should be spent on brushing — and the little girl loved it. “She thought that was super fun, that she would turn the timer on and she would brush her teeth for that long,” Nancy said.
Ashby was also treated to a shopping trip for oral-hygiene supplies with Mom. “She got to go with me and choose the toothpaste that she wanted,” Nancy recalled. “They had some SpongeBob toothpaste that she really liked, so we made it into a fun activity.”
Seems like this savvy mom is on to something! Just because good oral hygiene is a must for your child’s health and dental development, that doesn’t mean it has to feel like a chore. Equally important to making oral-hygiene instruction fun is that it start as early as possible. It’s best to begin cleaning your child’s teeth as soon as they start to appear in infancy. Use a small, soft-bristled, child-sized brush or a clean, damp washcloth and just a thin smear of fluoride toothpaste, about the size of a grain of rice.
Once your child is old enough to hold the toothbrush and understand what the goal is, you can let him or her have a turn at brushing; but make sure you also take your turn, so that every tooth gets brushed — front, back and all chewing surfaces. After your child turns 3 and is capable of spitting out the toothpaste, you can increase the toothpaste amount to the size of a pea. Kids can usually take over the task of brushing by themselves around age 6, but may still need help with flossing.
Another great way to teach your children the best oral-hygiene practices is to model them yourself. If you brush and floss every day, and have regular cleanings and exams at the dental office, your child will come to understand what a normal, healthy and important routine this is. Ashby will certainly get this message from her mom.
“I’m very adamant about seeing the dentist regularly,” Nancy O’Dell said in her Dear Doctor interview. “I make sure that I go when I’m supposed to go.”
It’s no wonder that Nancy has such a beautiful, healthy-looking smile. And from the looks of things, her daughter is on track to have one, too. We would like to see every child get off to an equally good start!

Finally — your braces are off! A look in the mirror reveals a straighter, more attractive smile. Unfortunately, it may also show something not so attractive — tiny, chalky spots on your teeth.
These “white spot lesions” are created by acid remaining too long in contact with the enamel, causing it to lose minerals at those places. The acid comes from plaque (a thin film of bacteria and food particles) that brushing and flossing fail to remove. Snacking on foods and beverages with added sugar or high acid content may also make it worse.
Besides their unattractiveness, these spots can lead to tooth decay — so it’s important to try to prevent it. Limiting sugar-added snacks and acidic beverages to mealtimes will help, but the main key to preventing lesions is more thorough brushing and flossing.
Because of the braces, this can take longer to do than if you weren’t wearing them. It’s also more difficult maneuvering your toothbrush or floss around the orthodontic hardware. You can improve thoroughness and access by using a powered brush or one specially designed for use with braces. And, a water flosser that removes plaque between teeth with a pulsating spray of water is an effective alternative to string floss.
Even if (despite your best efforts) some lesions form, we can still treat them. Resuming normal hygiene practices after braces may take care of it — if not, we can strengthen the affected areas of the enamel with pastes, gels, or other topical fluoride applications. We can also use a technique called caries infiltration that injects tooth-colored resin (often used for cosmetic dentistry) beneath the white spot to harden it, and leave it more translucent in resemblance of normal enamel. If these fail to produce satisfactory results, we can use cosmetic bonding that permanently covers the tooth with resin or veneers.
It’s best, though, if you can prevent the lesions while you’re wearing braces. Besides daily hygiene, be sure to keep up regular dental visits for teeth cleaning. Your efforts will go a long way toward keeping your newly aligned teeth bright and blemish-free.
