Molars play a vital role in chewing, grinding, and maintaining the structure of your smile. Whether you’re a parent watching your child get their first molar teeth or you’re dealing with wisdom tooth pain, understanding when molars come in and how to care for them is essential to maintaining lifelong oral health.
At Platinum Smile Dentist Mandurah, we’re here to answer common questions about molar teeth, from timing and types to treatment and care.
What Are Molars?
Molars are one of the four main types of teeth, alongside canine teeth, incisors, and premolars. Located at the back of the mouth, molars have large, flat surfaces with ridges designed for grinding and breaking down food.
These teeth help prepare food for swallowing and digestion, supporting the digestive process and protecting your oral health by reducing the stress on your jaw and other teeth.
There are three sets of molars:
- First molars erupt around age 6 and are essential for early chewing function.
- Second molars come in around age 12 and sit behind the first molars.
- Third molars, also known as wisdom teeth, typically appear between ages 17 and 25. These third molar teeth often become impacted and may require removal.
Each type of molar tooth plays a unique role in maintaining alignment, bite strength, and the stability of surrounding teeth.
What Age Do You Get Your Molars?
Primary Molars in Children
Primary teeth, also called baby teeth, include baby molar teeth that erupt between the ages of 1 and 3. These teeth are vital for helping children chew food and develop proper speech patterns. As kids lose their baby teeth, permanent replacements begin to erupt.

Permanent Molars in Adolescents
First permanent molars, also known as “6-year molars,” emerge around age 6. These are the first adult teeth that do not replace baby teeth. Second molars erupt around age 12 and are sometimes called “12-year molars.”
These permanent teeth grow behind the primary teeth and play a critical role in forming the adult bite.
When Wisdom Teeth Typically Emerge
Third molars, or wisdom teeth, are the last set of molar teeth to appear. They usually erupt between the ages of 17 and 25. Some people never develop them, while others have all four wisdom teeth , two in the upper jaw and two in the lower.
If there’s not enough room in the jaw or the teeth come in at an angle, these third molars may become impacted, leading to discomfort or infection. Those with impacted wisdom teeth will typically need to have them removed.
How Many Molars Do Adults Have?
Most adults have 12 molars:
- 3 on each side of the upper jaw and lower teeth
- This includes first molars, second molars, and third molars (wisdom teeth)
In total, adult teeth typically number 32, including 8 molars in each arch.
The Impact of Wisdom Teeth on Total Molar Count
Due to wisdom tooth removal, many adults have fewer than 12 molars. Whether because of pain, lack of space, or misalignment, it’s common for wisdom teeth to be extracted.
While third molars aren’t necessary for proper chewing, their removal must be carefully managed to avoid complications like tooth loss, damage to surrounding teeth, or gum disease.
Common Problems with Molars
Wisdom Molar Pain and When to Extract
Wisdom molar pain is a common complaint among teenagers and young adults. It often results from impacted wisdom teeth, which can’t erupt properly due to limited space.
Signs of problematic third molar teeth include:
- Jaw swelling or stiffness
- Pain when opening your mouth
- Pressure on other teeth
- Red, inflamed gums around the tooth
In many cases, wisdom molar extraction is recommended to prevent infection, cysts, or misalignment.
Cavities and Decay in Molar Teeth
Molars have deep grooves that trap food and plaque, making them highly susceptible to tooth decay. Without proper brushing, severe decay can occur, leading to fillings, crowns on molars, or even molar tooth removal.
Routine check-ups help detect cavities early and preserve your permanent teeth.
Cost of Molar Removal and Treatment Options
The cost of molar removal varies depending on whether it’s a simple extraction or a surgical procedure. Impacted wisdom teeth typically cost more due to the complexity of the extraction.
In cases of decay or fracture, crowns on molars may be necessary to restore strength and function. Fillings or root canals may also be recommended to avoid tooth loss.
At Platinum Smile Dental, we provide clear treatment plans and upfront pricing to help you make informed decisions.
How to Care for Your Molars
Because of their location and shape, molars need extra attention to avoid cavities and plaque build-up. Here’s how to care for them:
- Brush twice daily, especially reaching the back teeth
- Use fluoride toothpaste to strengthen tooth enamel
- Floss daily to clean between molar teeth
- Rinse with an antibacterial mouthwash
- Schedule regular dental cleanings
Neglecting oral health can lead to decay in molars, gum inflammation, and eventually, tooth loss.
When Crowns or Fillings Are Needed
If your molar tooth has suffered from severe decay or a fracture, your dentist may recommend a crown to protect it. Crowns on molars are designed to withstand heavy chewing and restore full function.
Fillings are used to treat minor cavities and prevent the damage from worsening. Early intervention is key to avoiding more invasive treatments.
