Growing Up: How Long Does a Tooth Take to Grow?

Growing up is tough. You have to deal with weird hair growth in new places, terrible twitches, suddenly discovering that your crush likes someone else who's clearly inferior to you - it's all madness! But one thing that should be easy (in theory) is the growth of teeth. Unfortunately, it isn't always so simple. Have you ever wondered how long does a tooth take to grow? Fear not my friend, for we shall delve deep into the mysteries of dental development.

Growing Up: How Long Does a Tooth Take to Grow?

The Basics

Before getting started on tooth growth timelines, let us first understand some basic concepts:

Primary Teeth vs Permanent Teeth

Humans get two sets of teeth - primary and permanent. Primary teeth are also known as baby or milk teeth while permanent ones replace them later in life.

Anatomy of a Tooth

A tooth has four main parts: - Crown: Visible part above gumline - Root: Hidden part below gumline - Enamel: Outer layer covering crown - Dentin: Layer beneath enamel

Stages of Development

Tooth development occurs in three stages: 1. Bud Stage: Initial formation within gums. 2. Cap Stage: Differentiation into different structures such as enamel and dentin. 3. Bell Stage: Completion of differentiation and hardening begins.

The final stage sees calcium deposited in the forming hard tissues like cementum on root surfaces.

Now that we've covered these basics let’s dive deeper!

When Do Teeth Develop?

Teeth develop during prenatal and postnatal periods . That means they can emerge before birth or after at any time from months onwards until adolescence or even young adulthood!

Thankfully though most people will only have their last wisdom tooth come through by mid-twenties at latest but this varies depending on individual factors involved such as genetics amongst other things

Let’s talk about when specific sets develop.

Primary Teeth

Primary teeth start developing during the embryonic period (4-6 weeks after conception). They generally start to erupt into the mouth when a baby is around 6 months old, but this varies from around 3 months onwards up to a year in some cases. It typically takes two years for all primary teeth to emerge.

Permanent Teeth

The first permanent teeth usually begin their development journey behind primary molars at around six years of age. The final wisdom tooth emerges sometime between ages seventeen and twenty-five. This means that we will have both milk and permanent sets in our mouths-two layers like an Oreo!

How Long Does Tooth Eruption Take?

Tooth eruption or emergence refers to when its crown breaks through gums surface and can be seen The timing of dental emergence differs by type as well with primary successors arriving much later compared with incisors which appear much earlier

For example , Lower central front incisors are among earliest starting their growth at three months on average while second molars are last .

Below is given an approximate timeline:

Type Age Range
Central Incisor 7-12 Months
Lateral Incisor 9-13 Months
Canine 16-22 Months
First Molar 13 -19 Months
Second molar 25 -33 Months

Note: Milestones vary according to individual factors such as environment, diet, genetics amongst other things.

Thus it can be shown that children experience week-to-month intervals before each new dental set reach full completion; If you're wondering why these variance exists then read on!

What Causes Variance In Tooth Growth?

Multiple factors influence how quickly or slowly teeth develop. Some include:

Nutritional Status

Nutritional deficiencies arising from inadequate intake may lead delayed onset of teething.

Genetic Factors

It’s important to know that individual differences exist regarding the timing of tooth development.


Research also shows that female children reach their milestones faster due to hormonal changes; estrogen which regulates calcium metabolism in bone formation such as teeth.

Good news for all you girls out there – fast teething!

What About Child Tooth Loss?

Plenty of things induce child teeth loss including, but not limited to:



genetic abnormalities

Remember that primary teeth assist kids with speaking, eating and give a foundation upon which adult dentition sets can grow on.

When baby teeth fall out depends on each individual’s unique timeline. It is therefore recommended by dental practitioners the average age seven act as baseline when permanent replacements would emerge about 2-3 years after this point… although yours may come sooner or later than this!


Conclusively one could averagely say:

• A new infant will have twenty milk pearly whites coming up over various intervals until they are two.

• They then start exchanging them from about six till twelve before finishing off with wisdoms emerging anywhere from 17 onwards until early-mid twenties…

and it’s worth pointing out no two stories unfold precisely alike so never compare your bodily timings to others too closely.

Hopefully, we've shed light on how long does a tooth take to grow?.So next time somebody asks "what's taking my sweet little prince/princess so long?!” when those precious fangs refuse emergent pressure remind them maturity takes its own path–and if all else fails make 'em laugh at explanations found therein instead
