Did you know that molars are essential for breaking down food, but not everyone has the full set?
Wondering how many molars do adults have? Most adults have a total of 12 molars—three on each side of both the upper and lower jaws. These molars serve a specific purpose in the process of chewing and grinding food, making digestion easier and more effective. Positioned at the back of the mouth, molars are also larger and stronger than other teeth, built to handle the daily wear and tear of chewing.
The first and second molars, located just after the premolars, typically appear around age 6 and 12 and are essential for primary grinding. These molars are present in nearly all adults and are fundamental for thorough chewing. The third molars, known as wisdom teeth, are the final set to develop and usually appear in the late teens to early twenties. However, it is not always the case that all adults retain their third molars.
The Role of Wisdom Teeth
Wisdom teeth, or third molars, are believed to be from our ancestors, who had larger jaws and diets that required heavy chewing of tough, coarse foods like roots, nuts, and raw meat. These foods caused significant wear on teeth, and the extra set of molars helped replace teeth that wore down over time, ensuring better chewing ability throughout life.
As humans evolved, so did our diet and jaw size. As we naturally started introducing cooking and softer foods, there was less need for extra molars. Additionally, human jaws became smaller over time, leaving less space for wisdom teeth to erupt properly. This often results in crowding, impaction, or misalignment of the wisdom teeth, causing discomfort and potential dental issues.
Today, many people have their wisdom teeth removed to avoid these complications, as they no longer serve a functional purpose in modern diets and lifestyles. However, they remain a natural part of human dental development, even if their role has become less essential.
Common Issues Related to Molars
Molars can be prone to several common dental issues due to their location and function. Tooth decay and cavities are frequent concerns, as molars’ grooves and ridges can trap food particles and bacteria, increasing the risk of decay. Over time, molars also experience significant wear and tear from chewing, which can lead to fractures or cracks, especially if grinding or clenching habits are present.
Looking After Your Oral Health
Maintaining healthy molars is essential for overall oral health. Effective brushing and flossing techniques are vital, especially reaching the back teeth to remove trapped food particles and plaque. Regular dental check-ups allow dentists to monitor molar health, catch potential issues early, and offer preventive care.
A balanced diet that includes crunchy fruits and vegetables can naturally clean tooth surfaces and support gum health. By incorporating these habits, adults can help keep their molars strong and reduce the risk of decay, damage, or gum-related issues over time.
Treatment Options for Molar Problems
When molar issues arise, a range of treatment options are available to restore functionality and relieve discomfort. For mild cases of decay, restorative dentistry such as fillings is often the first line of defence. Fillings repair small cavities, stopping the decay from spreading and preserving the tooth’s natural structure. For more significant damage, crowns may be recommended, as they cover and protect the entire molar, restoring its strength and durability.
If decay or infection reaches the inner pulp of the molar, root canal therapy may be necessary. This procedure involves removing the infected tissue from within the tooth, cleaning the area, and sealing it to prevent further infection. Root canals can effectively save a damaged molar, allowing it to function like a healthy tooth.
In cases where a molar is too damaged to repair, or if wisdom teeth are causing alignment issues, extraction may be the best option. Molar extractions are commonly performed when wisdom teeth become impacted or if other molars are severely compromised. By removing problematic teeth, extraction can relieve pain and protect surrounding teeth from further complications.

FAQs
What is the purpose of sealants for molars?
Sealants are protective coatings applied to the chewing surfaces of molars, filling in grooves where food and bacteria may accumulate. They are especially helpful in preventing cavities in children and teens.
Are all adults’ third molars removed?
Not necessarily. If wisdom teeth erupt without issues and align well, they can remain. However, many people have them removed due to crowding or alignment problems.
How can I keep my molars healthy?
Regular brushing and flossing, especially reaching back to clean the molars, along with routine dental check-ups, are key to maintaining healthy molars. A diet with crunchy fruits and vegetables also promotes molar health.
