Babies typically start teething at four to six months, developing their first teeth at 6 to 12 months old. Though these primary teeth eventually fall out to make way for a permanent set, they can still be vulnerable to cavities and necessitate dental fillings. Here's what to know about this dental problem and how to correct it. 

What Causes Baby Cavities?

Like adults, babies can get cavities, also known as dental caries. These small holes develop when bacteria in plaque consume the sweet residues in juices, milk, and formula that linger on tooth surfaces. As a result, they rapidly reproduce in the mouth, weakening the enamel. Putting babies to sleep with bottles can increase the risk of cavities, exposing an infant's teeth to sugary substances for prolonged periods.

When Do They Require Dental Fillings?

Since baby teeth are temporary, they often don't require fillings. For instance, minor decay on a tooth typically manifests as small white spots, which you can clean with a small brush and a pea-sized amount of fluoride paste. This approach can help remineralize the tooth and prevent decay from progressing into a cavity. 

Older kids who develop cavities might not need fillings if the affected primary teeth are loose and close to falling out. However, in the case of infants and small children, dental caries can quickly expand. This situation allows bacteria to enter the inner tooth pulp, leading to pain and infections. Additionally, it can spread to neighboring teeth, causing more extensive decay in the mouth.

You should have your child's cavities filled as soon as a pediatric dentist detects them. The process involves drilling out the decayed segments and filling them with amalgam, composite, or porcelain. The procedure is typically quick, and a dental care provider will numb the tooth and surrounding area to prevent discomfort.

How Can I Prevent Them?

Visiting a dentist for children around your child's first birthday, and making biannual appointments after that, will help keep primary teeth clean and reduce the risk of cavities. During the sessions, a dentist will examine the teeth, detecting and treating any problems before they worsen.

You can also help prevent cavities by gently running a damp washcloth over your baby's gums to cleanse bacteria from the mouth. Once your child's first teeth erupt, use a small brush and fluoride paste to remove cavity-causing microbes once daily. Additionally, limit their consumption of sugary foods and drinks to reduce the amount of sugar on tooth surfaces.
