What Are Wisdom Teeth? Function, Location & Anatomy

April 1, 2025

Introduction

Wisdom teeth are the third set of molars that usually come in during early adulthood. Although they were vital to our forebears, contemporary diets and dental development have rendered them redundant to some extent. Oftentimes, they cause pain, crowding, and infection, and as such, most individuals ask the question: Is wisdom tooth extraction necessary?

This article will explain what wisdom teeth are, their function, location, and anatomy. We will also discuss why wisdom teeth are removed and where to get the best Wisdom Teeth Removal in HSR Layout and Koramangala at a popular dental hospital in Koramangala.

What Are Wisdom Teeth?

Wisdom teeth are the third molars that are located in the rear of the mouth. They typically erupt between ages 17 to 25. There are some people who have all four wisdom teeth, while others may have less or none at all.

Earlier, these teeth played an important role in enabling our ancestors to chew raw meat, nuts, and tough vegetable material. With the introduction of modern diets and oral hygiene, however, wisdom teeth have become very redundant, typically leading to issues such as impaction, infection, and crowding.

Role of Wisdom Teeth

Wisdom teeth had a functional role in our ancestors’ diets. This is how they helped:

  • Grinding Tough Foods – Wisdom teeth were backup molars that ground tough meat, nuts, and roots.
  • Replacing Lost Teeth – Early humans lost their teeth at an early age, so wisdom teeth were a backup chewing force.
  • Aiding Digestion – Wider jaws allowed early humans to chew food more effectively, which aided digestion.

With advances in oral hygiene, soft foods, and modern dentistry, wisdom teeth are unnecessary, and oftentimes, they are a source of pain instead of a blessing.

Location & Anatomy of Wisdom Teeth

Wisdom teeth are located at the back of the mouth, behind the second molars.

1. Number & Position

  • Upper Jaw (Maxillary Wisdom Teeth) – Two at the back of the upper jaw.
  • Lower Jaw (Mandibular Wisdom Teeth) – Two that are found at the back of the lower jaw.

2. Structure & Growth Pattern

Wisdom teeth are similar to other molars but can have unusual growth patterns, which can lead to impaction or crowding. Some of the usual growth issues are:

  1. Erupting at an angle – Can push against the other teeth, creating pain.
  2. Partially Erupted – Provides an entry point for bacteria, leading to infection.
  3. Completely Impacted – Trapped below the gums, and effective roots may be harmed.

Why Wisdom Teeth Are Removed?

Many people experience discomfort, swelling, and complications due to their wisdom teeth. Following effective reasons why wisdom teeth are removed:

  1. Impaction & Pain

Impacted wisdom teeth may lead to terrible aches, swelling, and infection. Therefore, immediate dental attention is required.

  1. Overcrowding

The contemporary jaw is narrower than that of our forebears, often with inadequate room for wisdom teeth, which leads to crowding and misalignment.

  1. Infection & Decay

Partially erupted wisdom teeth leave space for bacteria and food particles to get trapped, which increases the risk of:

Cavities

Infections of the gums (Pericoronitis)

Abscesses

  1. Cyst Formation

Impacted wisdom teeth develop cysts or tumors in some cases, destroying adjacent teeth, nerves, and jawbone.

  1. Difficulty in Cleaning

Wisdom teeth are located at the back of the mouth, making them hard to clean, and thus leading to plaque buildup and gum disease.

Is Wisdom Teeth Extraction Necessary?

The necessity of wisdom teeth extraction depends on the following:

 ✅ Pain, swelling, or infection

 ✅ Possibility of crowding or malalignment

 ✅ Partial eruption that complicates cleaning

Unless wisdom teeth become problematic, their removal may not be necessary. It is still better to keep a regular check in order not to have future problems.

Procedure for Wisdom Teeth Removal

1. Consultation & Diagnosis

A HSR Layout Bangalore dentist will inspect your wisdom teeth with X-rays to observe:

The growth pattern

  1. Any sign of impaction
  2. Any danger of overcrowding or infection

3. Extraction Process

Wisdom teeth extraction is a common outpatient procedure, usually done under general or local anesthetic.

  1. Incision – The dentist makes a small incision in the gum.
  2. Tooth Removal – The wisdom tooth is removed intact or in pieces.
  3. Stitching & Healing – The gum is stitched (if necessary), and the healing process begins.

4. Recovery & Aftercare

Healing from surgery requires about a week. Some key aftercare instructions are mentioned below:

✔️ Apply ice packs to reduce swelling.

 ✔️ Eat soft foods like soup, yogurt, and mashed potatoes.

 ✔️ Avoid smoking, drinking, and straws to prevent dry sockets.

 ✔️ Take prescribed medication for pain.
