Can wisdom teeth grow back

No, wisdom teeth will not grow back once removed. Wisdom teeth, are the final set of adult teeth to emerge, usually in late teens or early twenties in humans. 

Primary teeth which are replaced, wisdom teeth do not have any successor teeth waiting in the jawbone. When an impacted or problematic wisdom tooth is extracted by a dentist, it is permanently gone. 

The extraction site heals up with new bone growth within a few months, closing off that space. While neighboring teeth may shift slightly to adjust to the new position, nearby tissues and bone stabilize the jawline over time. 

Since there is no replacement tooth bud present after removal, it is not possible for a wisdom tooth to regenerate or break through the gums again at a later date. Once taken out, they are gone for good.

What Are Wisdom Teeth

Wisdom teeth, also known as third molars, are the last teeth to erupt in the mouth of human, usually in between ages sixteen to twenty . Unlike primary or baby teeth that are replaced, wisdom teeth have no predecessors. 

They develop from tooth buds at the very back of the jawbone and must travel through the gums and bone to reach the chewing surface. Often there is not enough room for wisdom teeth to emerge properly, leading to conditions like impacted teeth that are stuck or crooked. 

Wisdom teeth can also develop cavities or gum disease more easily due to their difficult access for cleaning. When problem wisdom teeth cause issues like recurrent infections, pain, or damage to other teeth, dentists may recommend extraction to prevent future dental problems. 

In general, humans have eight wisdom teeth total, with four each in the upper and lower back sections of the mouth. Their name originates from the notion that these final teeth represent the growth stage of wisdom and maturity.

Why we have wisdom teeth?

Wisdom teeth, or third molars, are evolutionary taken from our ancestors who had larger jaws with more room for teeth. Throughout history, as human jaws have been getting smaller, wisdom teeth are often impacted or unable to fully erupt.

Our ancient ancestors hundreds of thousands of years ago had bigger mouths to accommodate a larger number of teeth to help grind their tougher, fibrous diets. Wisdom teeth helped replace earlier molars that wore down over time with heavy chewing.

As modern diets became softer, human jaws started evolving to be smaller. But the genetic blueprint for wisdom teeth remained. These days, about 70% of people don’t have enough room for all 32 teeth, resulting in problems like crowding, small jaws, and impacted or unerupted wisdom teeth.

While serving little purpose today, wisdom teeth haven’t yet been phased out by evolution since they generally cause issues in adulthood after reproductive years. 

Wisdom teeth are evolutionary leftovers that no longer suit our modern oral structures and lifestyles. Many dentists recommend removing them preemptively to prevent problems down the road.

can wisdom teeth grow back

No, wisdom teeth will not grow back once it  removed.

  • They develop from tooth buds deep in the back portion of the jawbone.
  • Often there is inadequate space for wisdom teeth to emerge properly, leading to impaction or infection risks.
  • When impacted or affected by dental problems, dentists may extract wisdom teeth.
  • Wisdom teeth are the third and final set of permanent molars humans develop.
  • Unlike primary/baby teeth that are replaced, once an adult permanent tooth is removed, the tooth bud is gone and will not regenerate a new tooth.
  • After extraction, the empty socket will heal over with new bone tissue within a few months.
  • While the space initially feels odd, surrounding teeth and tissues stabilize to maintain proper jaw structure.
  • In rare cases of incomplete extraction, small pieces of tooth may remain, but this does not constitute true tooth regrowth from the root.
  • Properly performedwisdom tooth removal is a one-time procedure, as there is no biological ability or process for these teeth to re-emerge later.

Can wisdom teeth fall out naturally?

It is possible for wisdom teeth to fall out naturally without needing extraction, but it is not very common. In some cases where sufficient room exists in the jaw, wisdom teeth may erupt similarly to other molars with little issue.

As a person ages, teeth can loosen naturally to some degree due to aging of gums/bones supporting them.On rare occasion, a wisdom tooth with no pathological issues may loosen and be exhaled from the mouth without intervention.

However, partially boney impactions or inflamed/infected tissues often mean extraction is needed. Most wisdom teeth develop problems and require surgical removal to prevent future damage.

But in limited cases with ample jaw room and no dental concerns, a wisdom tooth could potentially fall out as a natural occurrence later in life rather than extraction.

Why Remove Wisdom Teeth?

Lack of Space

As the jawbone finishes developing in late teens/early 20s, there is often not enough room for wisdom teeth to fit properly since they are the last to erupt.Insufficient space leads to teeth becomingMesially, horizontally, or vertically impacted as they try to come in at abnormal angles.Impacted teeth cannot fully erupt and are difficult to clean around. Food and bacteria get trapped, increasing risk of decay and gum disease.

Risk of Impaction

Mesial (sideways) impactions occur when there is inadequate room between the wisdom tooth and the second molar.Horizontal (flat) impactions mean the tooth is trapped sideways under the gumline and bone.Vertical (standing upright) impactions have the crown stuck in the bone above the gum.Any impaction type makes the tooth restless and prone to inflammation, infection, and cysts or tumors over time.

Potential for Infection

When wisdom teeth are partially or fully bony impacted, plaque and food debris easily get lodged around them.The trapped bacteria and lack of cleaning leads to inflammation and infection of the gum tissues (pericoronitis).Left untreated, these infections can spread, potentially causing facial swelling, fever, and even inflammation of the jawbone itself (osteomyelitis).

Damage to Other Teeth

As an impacted wisdom tooth attempts to erupt, it can exert pressure on the second molar, causing its root to be resorbed over years.This damages the second molar irreparably in many cases. Adjacent teeth may also become crowded or pushed out of alignment.

Cysts or Tumors

Cysts form when tissues surrounding trapped teeth break down and fill with fluid. Over years, cysts may grow quite large and put pressure on nearby structures like nerves and roots of other teeth.Though very rare, odontogenic tumors are non-cancerous growths that can develop from the breakdown of impacted tooth’s cellular lining. Early removal prevents these risks.

Difficulty with Oral Hygiene

Reaching back to fully clean between wisdom teeth and second molars is difficult even with floss and special brushes.Plaque easily stays in hard to reach areas, increasing risks of decay, gum disease, abscesses that require extraction down the road if left there.

Preventing Future Problems

Early removal before major issues arise is usually best practice to maintain long-term oral health throughout adulthood and senior years. This head offs future complexities from delayed extraction.

Key takeaways

  • Wisdom teeth are the last molars to erupt, usually late teens to early 20s.
  • Often don’t have space, leading to impaction against other teeth.
  • Impacted teeth can’t be cleaned fully, raising risk of cavities and infection.
  • Extraction recommended if impacted, crowded, or infection is present.
  • Will not regrow after removal, as there is no replacement tooth bud. Socket heals with bone only.
