The age of six often marks a significant developmental milestone in a child’s mouth as new teeth begin to emerge. This period sees the start of a long process where the primary, or baby, teeth are gradually replaced by a permanent set. The emergence of these new teeth signals the beginning of the adult dentition that will last a lifetime. Understanding this transition is helpful for parents to support their children’s oral health.
The Six-Year Molars: Identification and Role
The answer to whether molars come in at age six is typically yes, and these teeth are known as the first permanent molars. They are often called “six-year molars” because they generally erupt between the ages of six and seven, though the timing can vary slightly due to genetic factors. These are the largest teeth in the mouth and are the first of the permanent molars to appear.
These molars are unique because they do not replace any existing baby teeth; instead, they emerge into the space directly behind the last primary molars. A child will get four of these teeth, two on the top and two on the bottom, positioned at the very back of the mouth. Their eruption is important for establishing the correct bite, or occlusion, between the upper and lower jaws. They help guide the alignment and positioning of all the other permanent teeth that follow.
What to Expect During Eruption
The process of these molars breaking through the gums, known as eruption, can cause some discomfort for the child. Common physical signs include localized gum inflammation and swelling in the area where the tooth is pushing through. This tenderness can sometimes make chewing solid foods difficult or painful.
Symptoms associated with this eruption can also include a mild, low-grade fever, jaw pain, or headache. For most children, the acute gum discomfort lasts for about a week, though the full eruption process can take several months. Parents may also notice the child biting their cheek more frequently as the wide chewing surface of the new molar first emerges and takes up space in the back of the mouth.
Essential Care and Maintenance
Because the first permanent molars are meant to last a lifetime, protecting them from decay as soon as they emerge is important. One highly effective preventative measure is the application of dental sealants, which are thin, plastic coatings painted onto the chewing surfaces. Sealants flow into the deep pits and grooves of the molars, creating a smooth surface that blocks out food particles and bacteria, which are the main causes of cavities.
Brushing these new back teeth requires special attention due to their position and large surface area. Parents should supervise brushing twice a day with fluoride toothpaste and ensure the brush reaches all the way to the back molars. Fluoride works alongside sealants by strengthening the enamel, making teeth more resistant to acid attacks. Regular dental checkups every six months are necessary so the dentist can monitor the eruption, ensure the teeth are protected with sealants, and check for any signs of early decay.
