How Long Does it Take a Wisdom Tooth to Come in Once It Begins?

October 1, 2023

Wisdom teeth, scientifically known as third molars, make their appearance during the ‘age of wisdom,’ typically between ages 17 and 25. These teeth are relics of our evolutionary history when our ancestors needed strong jaws for a rougher diet. Understanding their role in dental health is essential.

Why do we have wisdom teeth?

Our ancestors relied on wisdom teeth to chew tough foods like roots, nuts, and meats. However, over time, changes in our diet and jaw structure have rendered these teeth largely unnecessary. As a result, many individuals experience complications when their wisdom teeth try to erupt.

Where are they located?

Did you know that wisdom teeth are actually located at the back of your mouth, right behind your second set of molars? Usually, most folks have four wisdom teeth – two on the top and two on the bottom – and they’re usually positioned symmetrically.

Wisdom Teeth Development

Early Formation

The development of wisdom teeth begins in the adolescent years. The initial signals for growth are triggered by biological factors, including genetic cues and hormonal changes during puberty. There is a complicated interaction between the genes and the environment that plays a role in the development of wisdom teeth.

Stages of Development

Stage 1: Initial Formation

During the initial formation stage, wisdom teeth develop within the jawbone. This process, known as odontogenesis, involves the gradual formation and growth of tooth buds. The number of wisdom teeth one possesses varies, with some individuals having all four while others may have fewer or none at all.

Stage 2: Eruption Process

Once they have formed, wisdom teeth embark on a journey towards the surface. As they push through the gums, many factors can influence the timeline of their eruption. These factors include genetic predisposition, jaw size, available space, and oral hygiene practices.

Signs of Wisdom Teeth Coming In

During the eruption process, individuals may experience various signs that indicate the emergence of wisdom teeth. These symptoms often include pain, swelling, redness of the gums, jaw stiffness, and even headaches. It is important to recognize these signs to seek appropriate dental care.

The Timeline of Wisdom Teeth Eruption

Upper Wisdom Teeth

Eruption of first upper wisdom tooth

The first upper wisdom tooth usually starts erupting between the ages of 17 and 21. It may take several months for the tooth to fully emerge.

Eruption of second upper wisdom tooth

The eruption of the second upper wisdom tooth typically follows shortly after the first, around the ages of 18 to 22.

Eruption of third upper wisdom tooth

In some cases, a third upper wisdom tooth may develop, but this is relatively uncommon. If it does occur, it usually emerges between the ages of 19 and 23.

How Long Does it Take for an Upper Wisdom Teeth to Come in Once It Begins?

Upper wisdom teeth usually take anywhere from a few weeks to several months to fully come in. Well, it really depends on a few things like how healthy your mouth is and how much room there is for your teeth to come in. So, the exact amount of time can vary.

Lower Wisdom Teeth

Eruption of first lower wisdom tooth

The eruption of the first lower wisdom tooth generally occurs around the ages of 18 to 24. Similar to upper wisdom teeth, it may take several months for a complete eruption.

Eruption of second lower wisdom tooth

Following the first lower wisdom tooth, the second lower wisdom tooth typically appears between the ages of 19 and 25.

Eruption of third lower wisdom tooth

Similar to upper wisdom teeth, the emergence of a third lower wisdom tooth is rare. If it does arise, it can occur between the ages of 20 and 26.

Oh, the eruption time for lower wisdom teeth can actually vary quite a bit! It can take anywhere from a few weeks to several months for them to come in. How long it takes to complete the procedure can vary depending on factors like your oral health, how much space is available, and how your teeth are positioned.

Factors Influencing Wisdom Teeth Eruption Time

Several factors can influence the timeline of wisdom teeth eruption:

Genetics: Did you know that genes have a big impact on whether or not we have wisdom teeth and how they grow? It’s pretty fascinating! Individuals with a family history of early or late wisdom teeth eruption are likely to follow a similar pattern.

Jaw Size and Available Space: Limited jaw size and insufficient space can impede the eruption process. In such cases, the wisdom teeth may become impacted or stuck in the jawbone.

Oral Hygiene: Maintaining good oral hygiene practices can positively impact the eruption timeline of wisdom teeth. Proper brushing, flossing, and regular dental check-ups help prevent infections and promote healthy tooth development.
