The Truth About Babies' Teeth: Two Sets or One?


The Basics Of Baby Teeth

Baby teeth, also referred to as milk teeth or primary teeth, are the first set of teeth that babies grow. These teeth typically start developing during pregnancy and should have erupted by the time the child is three years old.

The purpose of baby teeth is to help the child speak, eat, and facilitate the growth of permanent teeth. Teeth development should start between six to ten months of the child’s life. Parents should contact a dentist within six months of teeth eruption to begin proper dental care.

Baby teeth play a crucial role in a child’s dental health, as improper care could lead to decay and infections. Ensuring proper oral care is a must. Parents should expect the following teething signs; discomfort associated with swollen and sore gums, fussiness, drooling, and loss of appetite due to the discomfort.

The pain during teething can be alleviated through use of teething toys, massage, and other methods.

The Truth About Two Sets Of Teeth

Humans are born with two sets of teeth, the first being baby teeth and the second being permanent teeth. Baby teeth develop in the womb and typically start appearing in the first 6-12 months of life. Permanent teeth begin to develop around the ages of 6-7 and are usually fully formed by the age of 12-14.

Baby teeth fall out because the roots dissolve and make room for the permanent teeth to come in. Each set of teeth contains a different number of teeth, with baby teeth having 20 and permanent teeth having 32. Knowing about these two sets of teeth can help parents and children understand the importance of proper dental care at every stage of life.

The Pros And Cons Of Two Sets Of Teeth

Babies are not born with both sets of teeth. However, they do grow their first set of teeth in their first couple of years of life. While having two sets of teeth may seem like a nuisance, it actually comes with a few advantages.

For one, baby teeth act as placeholders for adult teeth. Without them, adult teeth can grow in crooked or too close together. Losing baby teeth early can cause some challenges, like difficulty eating and speaking. It can also lead to complications like gum disease and infection.

It’s important to take care of both sets of teeth to ensure proper oral health throughout life.

How To Care For Baby Teeth

Babies aren’t born with both sets of teeth. You should start brushing baby teeth as soon as they come in. Choosing the right toothbrush and toothpaste is crucial. Cleansing and flossing baby teeth may seem unnecessary but it’s important. Diet plays a significant role in the health of baby teeth.

Other factors like genetics, fluoride exposure, and oral habits also contribute to healthy baby teeth.

When To Seek Professional Help

It is common for babies to be born without teeth, but some may be born with one or two. Regular dental check-ups are important to help detect any potential issues and address them promptly. Look out for signs such as difficulty eating or irritability.

Visiting a pediatric dentist can help address any issues and ensure a successful visit by bringing along comforting items for the child. It is essential to establish good oral hygiene habits early on to prevent future problems. So don’t hesitate to seek professional help for your child’s dental health.
