The transition from a baby full of tiny teeth to one sporting an adult smile is a major milestone. Around age six, your child will begin losing their primary or baby teeth, making way for the permanent set. This is an exciting time, but it often comes with questions and a few new challenges for parents.
The first permanent teeth to appear are usually the first molars and the lower central incisors. Knowing what to expect during this eruption period will help you guide your child toward a lifetime of great oral health.
First Permanent Teeth: The Six Year Molars
The first permanent teeth, often called the six year molars, are the most notable arrivals because they erupt behind the last baby teeth, meaning they do not replace a primary tooth. They simply push their way into the back of the jaw.
- Timing: They typically emerge between the ages of six and seven.
- The Surprise Factor: Because they do not cause a baby tooth to fall out, their arrival can sometimes go unnoticed. You might only realize they have arrived when your child complains of dull discomfort in the back of their jaw.
- Purpose: These molars are the foundation of your child’s bite. They anchor the jaw and establish the correct position for all the later permanent teeth to follow.
- Soreness: Expect some mild discomfort, tenderness, or a slight headache. Over the counter pain relievers and a cold compress can help ease the temporary soreness.
Due to their location at the very back of the mouth, these molars are prime targets for decay. They have deep grooves and pits where food particles and bacteria love to hide. This makes the newly erupted six year molars ideal candidates for dental sealants, a protective plastic coating we can apply to prevent cavities.
The Incisors: The Wobbly Wait
The second set of permanent teeth to arrive are typically the lower central incisors, the two front teeth on the bottom. Their eruption is a much more dramatic event because it involves the famous wobbly tooth stage.
- Wobbling Time: Losing a baby tooth is the result of the permanent tooth dissolving the baby tooth’s root structure beneath the gums. This process usually happens slowly, causing the tooth to loosen over several weeks or months.
- The Look: The new permanent incisors are noticeably larger, less white, and often have slightly jagged edges called mamelons. These mamelons are completely normal and will wear down naturally over time as your child chews.
- The “Shark Teeth” Phase: Sometimes, the permanent tooth begins to erupt before the baby tooth has completely fallen out. This results in two rows of teeth, leading to the nickname “shark teeth.” While often temporary, if the baby tooth is firmly held after the permanent tooth has significantly erupted, it is best to visit us. We can quickly assist with the removal to ensure the new tooth has room to align properly.
Focus on Brushing and Fluoride
During this transition, consistent and proper oral hygiene is more important than ever.
- Brush the New Teeth: Ensure your child brushes the newly erupted permanent teeth carefully, especially those back molars. These new teeth are often taller than the surrounding baby teeth and need focused attention.
- Fluoride Protection: Fluoride toothpaste and regular professional fluoride treatments help strengthen the developing enamel of the new permanent teeth, making them more resistant to the acids that cause decay.
We are here at Tiny Teeth Big Smiles to monitor this entire process, ensuring every permanent tooth arrives safely and on schedule. Celebrate the change, maintain great habits, and enjoy the new big smiles!
