Tooth growth in adults is an important topic that raises many questions, particularly regarding when it stops and how age affects dental health. As people grow older, they may notice changes in their teeth, prompting them to seek accurate answers about when tooth growth ceases in adults and whether there are differences between genders, such as when tooth growth stops in females compared to males.
On the other hand, children go through specific stages of tooth development, which can be illustrated through a tooth eruption chart detailing the timing of each tooth’s emergence. However, as people age, some may wonder: At what age does tooth growth stop? Is there a possibility of teeth growing after the age of 20, especially in cases involving wisdom teeth or certain medical conditions that affect dental development?
In this article, we will explore the stages of tooth growth from childhood to adulthood, highlighting the changes that occur over time and the factors influencing dental health in adults.
Tooth Growth in Adults

Many people believe that tooth growth stops once permanent teeth have fully emerged. However, the truth is that changes in teeth can continue throughout life. Tooth growth in adults includes the development stages of permanent teeth, the impact of factors such as tooth loss or wisdom tooth eruption, and medical interventions that may be necessary to maintain oral health as one ages.

Tooth Growth in Adults

Tooth growth in adults goes through several stages and is subject to changes that can impact long-term oral health. Although permanent teeth usually emerge between the ages of 6 and 12, tooth development in adults may include important changes, such as:
Wisdom Tooth Growth: The last set of teeth to emerge, usually between ages 17 and 25, which can cause complications if there isn’t enough space for them.
Tooth Wear: Over time, enamel erosion can occur due to dietary habits or conditions like teeth grinding.
Tooth Movement: Teeth may shift over the years due to tooth loss or gum disease, affecting bite alignment.
Gum and Bone Reshaping: Gum recession or changes in the supporting bone structure may require medical attention to maintain oral health.
Orthodontic Needs: In some cases, adults may require orthodontic treatment to correct misalignment that develops over time.
Consistent dental care and regular visits to the dentist play a crucial role in maintaining oral health in adulthood and preventing potential issues.
My Unexpected Experience with Tooth Growth in Adulthood
I never thought I would face dental issues after turning 30, but what happened completely changed my perspective. I first noticed a mild pain in my lower jaw, which I ignored, assuming it was temporary. Over time, the pain intensified, and I felt an uncomfortable pressure while chewing. When I checked in the mirror, I realized that a new tooth was growing! I had no idea that tooth growth in adults could still occur, especially with a delayed wisdom tooth eruption.
I started searching for a specialized dental center and found Dant Turky Center, known for its excellent reputation in dental care. I booked an appointment, and from the first moment, I felt at ease due to their professionalism. After an X-ray examination, the dentist confirmed that I had an impacted wisdom tooth growing at an incorrect angle, causing pain and pressure on neighboring teeth. He explained my treatment options, and I chose a safe, painless extraction using local anesthesia.
Following the procedure, I received clear post-care instructions and continued follow-ups with the specialists. Within days, I experienced significant relief, and the discomfort was completely gone. More importantly, I realized the importance of monitoring dental health even in adulthood, as unexpected dental issues can arise.
I’m grateful to the Dant Turky Center team for their excellent care and professionalism in handling my case. Now, I smile with confidence, knowing my dental health is in safe hands for life!
When Does Tooth Growth Stop in Adults?
If you ask yourself, “When does tooth growth stop in adults?” you will find that it generally stops once permanent teeth have fully emerged. However, this does not mean that changes in teeth completely cease. Typically, all permanent teeth develop during childhood and adolescence, but in some cases, changes can continue into later stages of life. In general, the stages of stopping tooth growth can be outlined as follows:
Completion of permanent tooth growth: This occurs between the ages of 12 and 14 when permanent teeth replace baby teeth.
Wisdom teeth eruption: These usually emerge between the ages of 17 and 25, though some individuals may experience delays or never develop them at all.
Cessation of structural changes: After the mid-20s, no new teeth grow, but teeth may shift due to tooth loss or gum issues.
Changes with aging: Over time, teeth may wear down, gums may recede, and other structural changes can affect the appearance and function of teeth.

Here is a table outlining the reasons that may delay tooth growth in children:
| Reason | Explanation |
|---|---|
| Genetic factors | Delayed tooth growth may be inherited from one of the parents. |
| Nutritional deficiency | A lack of calcium, phosphorus, or vitamin D affects tooth formation. |
| Thyroid dysfunction | Thyroid disorders impact bone and tooth development. |
| Premature birth | Preterm babies are more likely to experience delayed tooth growth. |
| Health disorders | Conditions like Down syndrome or certain genetic diseases may contribute to delays. |
| Low birth weight | It affects overall body growth, including tooth development. |
| Infections or chronic illnesses | Conditions such as anemia or recurrent infections can slow down normal tooth growth. |
| Bone disorders | Some bone diseases can affect tooth and jaw development. |
Even though tooth growth in adults stops at a certain stage, continuous dental care is essential to maintain oral health and prevent unwanted changes over time.

When Does Tooth Growth Stop in Girls?

Everyone Wonders: When Does Tooth Growth Stop in Girls?
Tooth development in girls differs slightly from boys, as it generally progresses faster. Typically, the replacement of baby teeth with permanent teeth begins between the ages of 6 and 7, but the completion of tooth growth in girls occurs earlier than in boys. Here are the details:
-Baby Teeth: Start falling out between ages 6 and 7, making way for permanent teeth.
-Permanent Teeth Growth: Teeth stop growing once all permanent teeth have emerged, usually between ages 12 and 14.
-Wisdom Teeth: Typically appear between ages 17 and 21, though their eruption time varies based on genetic factors.
-Adult Tooth Changes: After age 20, new tooth growth does not occur, but changes such as tooth movement or orthodontic needs may arise due to environmental factors or tooth loss.
Thus, tooth growth in girls usually stops between ages 18 and 21, except in cases where wisdom teeth emerge later.

Teething Chart for Children
The eruption of teeth in children usually begins at around 6 months of age, with the lower central incisors appearing first, followed by the upper incisors and other teeth gradually. The primary (baby) teeth are typically fully developed between the ages of two and three, with a total of 20 teeth that help the child chew and speak properly. The timing of tooth eruption may vary from one child to another due to genetic and health factors. However, if teething is significantly delayed, it is advisable to consult a dentist to rule out any underlying health issues.

Here is a table outlining the timeline for the eruption of teeth in children:
| Type of Tooth | Eruption Time (Months) |
|---|---|
| Lower Central Incisors | 6 – 10 months |
| Upper Central Incisors | 8 – 12 months |
| Upper Lateral Incisors | 9 – 13 months |
| Lower Lateral Incisors | 10 – 16 months |
| Upper First Molars | 13 – 19 months |
| Lower First Molars | 14 – 18 months |
| Upper Canines | 16 – 22 months |
| Lower Canines | 17 – 23 months |
| Lower Second Molars | 23 – 31 months |
| Upper Second Molars | 25 – 33 months |

At what age does tooth growth stop?
Have you ever wondered at what age tooth growth stops?
Tooth growth stops after the permanent teeth have fully emerged, but certain factors can influence this process. Generally, the cessation of tooth growth occurs in specific stages:
-Baby Teeth: These start appearing early in life and are usually replaced by permanent teeth between ages 6 and 12.
-Permanent Teeth: The full set of permanent teeth is typically in place by ages 12 to 14, marking the end of most dental development.
-Wisdom Teeth: These are the last to emerge, often appearing between ages 17 and 25, though some people may never develop them.
-Later Changes: While no new teeth form after this stage, teeth may shift or experience wear and tear over time.
Thus, for most people, tooth growth stops entirely between ages 18 and 25, depending on the presence or absence of wisdom teeth.

Tooth Growth After the Age of Twenty
Tooth growth after the age of twenty generally stops once permanent teeth have fully developed. However, certain changes can still occur, especially concerning wisdom teeth. Here are some key points about how age affects teeth after twenty:
-Wisdom Teeth Growth: These are the last teeth to emerge, usually appearing between the ages of 17 and 25. In some cases, they may never erupt or remain impacted within the gums.
-Tooth Movement: After twenty, teeth may shift due to tooth loss, changes in gum structure, or bone density.
-Wear and Natural Changes: Over time, teeth may experience natural wear due to diet, daily habits like teeth grinding, or general aging, affecting their shape and function.
-Need for Orthodontic Treatment: Some individuals may require braces or aligners after twenty to address crowding or alignment issues that develop later in life.
While tooth growth is minimal after twenty, continuous oral care is essential to maintaining dental health and function.

Questions That May Come to the Reader’s Mind
1. Do Teeth Grow in Older Adults?
It is important to note that by the age of 12, all primary teeth have typically fallen out. Losing a permanent tooth means it will not regrow naturally. Therefore, if a molar is extracted at age 18 under normal circumstances, it will result in permanent tooth loss, with no new tooth growing in its place.
2. When Does Tooth Growth Stop in Adults?
There is no definitive answer to this question, but in most cases, tooth growth is likely to stop between the ages of 21 and 25, coinciding with the eruption of wisdom teeth.
3. Can Teeth Grow Back?
Under normal conditions, a tooth will not regrow after being extracted at age 22. Baby teeth begin emerging within the first few months of a baby’s life, typically between 6-12 months, and are fully developed by age two. These are gradually replaced by permanent teeth between the ages of 6-12.
Conclusion
In conclusion, tooth growth in adults is a complex process that primarily ceases after the eruption of permanent teeth and wisdom teeth. While new teeth do not grow beyond a certain age, changes in oral health can continue due to factors such as tooth loss or natural wear.
Therefore, maintaining oral health through regular dental care and check-ups is essential. Taking care of our teeth after the growth phase is key to preserving a healthy and bright smile for life.
