A Healthy Mouth for Baby
by Sarah J. Kerr, BA
The health of your baby’s mouth may be the last thing on your mind. After all, there are diapers to change and many feedings to think about. While baby’s first tooth is a milestone to remember, now is the time to think about how you will help your baby have a healthy mouth.
You may be familiar with the most common mouth problems to plague little ones, like teething and thrush. However, you may not know that cavities are the most common chronic disease in young children. Cavities can develop as soon as your baby gets their first tooth. Read more about common mouth problems and how to help your baby have a healthy mouth.
Most babies get their first tooth when they are 5-9 months old and have 6-8 teeth by their first birthday. New parents may dread teething, but many babies will sprout teeth with little more than some crankiness and extra drool. And, of course, chewing on everything they can get their hands on. Tips to help your baby get through teething include:
Thrush is a mild yeast infection of the mouth. It will look like white patches on your baby’s tongue and inner cheeks. Sometimes it may go away on its own, though usually you will need to give your baby an anti-yeast medication.
A breastfeeding mom with a baby with thrush may notice that their nipples are sore or very pink or that they have a lot of pain when their baby latches on. If you are breastfeeding, you may also need to treat your nipples for a topical yeast infection (not thrush) so that you and your baby do not pass the infection back and forth.
You may think that taking care of baby teeth is not important since they will just fall out anyway, right? But healthy teeth are important, especially for babies. Healthy teeth help your child chew and speak clearly. Your child’s baby teeth hold spaces for the adult or permanent teeth, and they can affect the way your child’s jaw grows. Spots or stains on your child’s teeth can be signs of tooth decay. If you see these on your child’s teeth, schedule a dental exam.
Start these healthy mouth habits now to ward off cavities before they form.

The dentist may also treat your child’s teeth with a fluoride solution during the visit.
