When Should Infants Start Fluoride Supplements and Dental Care?

When is it appropriate for infants and young children to take fluoride tablets or receive fluoride treatments?

Dear Dr.
Wu,
I have two daughters (twins) who are currently about 8 months old and have started to develop their primary teeth.
I have a few questions:
1.
When is the most appropriate time to start fluoride tablets or fluoride treatments?
2.
I have heard that fluoride can cause cancer; is there any truth to this?
3.
My babies have both upper and lower primary teeth and often grind their teeth, making noise.
Will this cause their teeth to become misaligned?
4.
How can I maintain the oral health of my infants' primary teeth?
5.
I have misaligned teeth; will this be inherited by my children?
Thank you.

1.
Fluoride tablets are usually given to children to dissolve in their mouths before bedtime, with one tablet taken daily, starting after the eruption of primary teeth.
Fluoride varnish application should begin only after the child can spit, typically around the age of three.
2.
Fluoride is not considered carcinogenic.
3.
There may be some impact.
4.
Brushing teeth every night before bed is crucial; parents can assist their children with brushing, and the use of fluoride tablets and varnish can also be beneficial.
5.
It is possible.

More Info

When it comes to the dental care of infants, especially those who are just beginning to develop their first teeth, there are several important considerations regarding fluoride supplementation and overall oral hygiene practices. Here’s a comprehensive overview based on the questions raised.

1. When to Start Fluoride Supplements: Fluoride is essential for the prevention of dental caries (cavities) in children. The American Dental Association (ADA) recommends that fluoride supplements can be introduced when a child is around 6 months old, particularly if they are at high risk for cavities. For infants who have started to develop teeth, fluoride varnish can be applied by a pediatric dentist as soon as the first tooth erupts. However, fluoride tablets are typically recommended for children who are older, usually around 2 to 3 years old, when they can better manage swallowing and spitting.

2. Concerns About Fluoride and Cancer: There has been some public concern regarding the potential carcinogenic effects of fluoride. However, extensive research has not substantiated these claims. The consensus among health organizations, including the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), is that fluoride, when used appropriately, is safe and effective in preventing tooth decay. It is important to use fluoride products as directed to avoid excessive exposure, which can lead to dental fluorosis, a condition that affects the appearance of teeth but is not associated with cancer.

3. Teething and Tooth Alignment: It is common for infants to experience teething discomfort, which may lead to behaviors such as grinding their teeth (bruxism). While occasional grinding is generally not a cause for concern, persistent grinding can potentially affect tooth alignment over time. If you notice that your child is grinding their teeth frequently, it may be worth consulting a pediatric dentist to evaluate any potential issues.

4. Oral Care for Infants: Establishing a routine for oral hygiene is crucial even before the first teeth appear. Parents should wipe their infant's gums with a clean, damp cloth after feedings. Once teeth begin to emerge, using a soft-bristled toothbrush with water (and a small amount of fluoride toothpaste for children over 2 years) is recommended. It’s important to brush twice daily, especially before bedtime, to remove plaque and food particles.

5. Genetics and Dental Alignment: Dental alignment can indeed have a genetic component. If a parent has misaligned teeth, there is a possibility that their children may inherit similar dental traits. However, environmental factors, such as oral hygiene practices and diet, also play a significant role in the development of dental health. Regular dental check-ups can help monitor your children’s dental development and address any concerns early on.

In summary, starting fluoride supplements and establishing a dental care routine early in life is essential for maintaining your children's oral health. Regular visits to a pediatric dentist can provide personalized guidance and ensure that any potential issues are addressed promptly. Remember, good oral hygiene habits formed in childhood can lead to a lifetime of healthy teeth.
