Your baby’s dental health might be the last thing on your mind with all the diaper changes and lack of sleep, even when their first teeth appear. Did you know, when the first tooth erupts between three and nine months, you as a parent should schedule your baby’s very first dental visit?

After that, the next one should not be scheduled later than at the age of one. While playing together with your baby or preschooler and having a wonderful time you may notice some light blemishes on their teeth when their mouth wide open. This is not unusual and you shouldn’t panic.

However, you need to take action when you notice any white spots on baby’s teeth. Most of the time it might be the first sign of tooth decay. It’s also possible that it can indicate your baby’s intake of fluoride is too much.

For those parents who only feed their little one’s formula, here is some advice for you. If permanently mixing your babies meals with water from the tap, you can put him/her at a higher risk to develop a mild dental fluorosis. This is a condition of slight chalky white spots on their teeth. Most of your public water systems have too much fluoride as it is added and nearly all of your water from your well contains natural fluoride, but only in a smaller amount.

This is done to assist in the prevention of tooth decay. The extra fluoride is fine for older kids and adults. Yet, it could sometimes be too much for your baby, especially if they are under six months old. If you want to be safe, rather use bottled water that is low in fluoride such as distilled, demineralized, purified de-ionized to mix your child’s formula.

Cavities and Decay

The very first signs you may notice of tooth decay among children, will most likely be white spots on their teeth. Most of the time it will appear on the gum line and will be a pale or chalky color.

When these spots turn yellow or brown, it implies that the decay had spread. Although, the good news about this is that it’s not too far gone to reverse the decay. You should immediately schedule a visit to your family dentist.

Your dentist will more than likely prescribe a mild fluoride treatment and while you are there he/she will clear any tartar and plaque off your child’s teeth. To receive fluoride in the early stages will help to reverse the decay through strengthening the tooth’s enamel. Thus, prevent the acid formation to wear away their teeth over time.


Nonetheless, discovering white spots on baby’s teeth may also be a sign that they are getting too much of something, even if it is supposed to be a good thing. It’s called fluorosis, which will develop when your baby gets too much fluoride.

Most of the time these white spots that develop on his/her teeth affected by fluorosis will hardly be visible except when your child visits your dentist. The spots might actually be streaky or blotchy.

On the other hand, there is also good news with fluorosis.

This condition will only develop when your child’s teeth are still busy forming. Once your child’s permanent teeth starts coming in, the fluorosis risk will drop. The other advantage of fluorosis is that it can actually be of help. Most of the time it can help your child’s teeth to resist decay better.

How Fluorosis Happens

Even though, fluorosis won’t be harmful to your child or his/her teeth, you need to take action. Ensure that your child doesn’t get too much but receives the right amount of fluoride. For a young child too much fluoride can be unhealthy. Because water is one of your major sources that contain fluoride, you will need to keep an eye on your child’s water intake daily.

It will be good to check on your child when he/she is brushing their teeth, make sure that they don’t go overboard with the toothpaste. You should help them brush their teeth with only using about a pea-sized amount of toothpaste on the brush. Explain to them that it will be enough to clean their teeth. Make sure they spit it out and don’t swallow the toothpaste. It will teach your child about proper oral health. Consequently, he/she can enjoy a healthy mouth starting from a very young age.

Thanks for your informative article. I didn't think any amount of fluoride was good, though, for anyone? I personally think it needs to be taken out of the water.

Hi, there...

I actually agree, we should have as little as possible fluoride, yet, it is recommended. Even so, I would also prefer they remove it from our water, I am sure our toothpaste and such has sufficient amounts in :-) Thanks for reading and sharing your thoughts.
