Wisdom Teeth

Wisdom Teeth Before & After
Wisdom teeth—also known as third molars—are the last set of teeth to erupt in the mouth, usually between the ages of 17 and 25. For many people, these teeth do not have enough space to grow in properly, which can lead to discomfort, infection, crowding, and other dental problems. As a result, wisdom tooth removal is one of the most common oral surgery procedures.
To help you feel informed and comfortable, this guide explains what wisdom teeth are, why they may need to be removed, what to expect during the procedure, and how to manage discomfort at home.
What Are Wisdom Teeth?
Wisdom teeth are the third and final set of molars located at the very back of the upper and lower jaws. Most people develop four wisdom teeth—two on top and two on the bottom—though some may have fewer or none at all.
These teeth erupt later in life, often after the jaw has fully developed. Because space is limited, many wisdom teeth become impacted, meaning they are stuck under the gum or bone and cannot erupt normally.
How Can Wisdom Teeth Affect Your Health?
Wisdom teeth don’t always cause problems. If they grow in straight, have enough space, and remain easy to clean, they may not need to be removed.
However, for many patients, wisdom teeth can lead to:
- Pain or pressure in the back of the mouth
- Gum inflammation or infection (pericoronitis)
- Tooth decay in the wisdom tooth or its neighbour
- Crowding or shifting of other teeth
- Cysts or bone damage around an impacted tooth
- Difficulty chewing or biting
Removing wisdom teeth early—typically before age 25—is recommended because the roots are not fully developed and the surrounding jawbone is softer. This makes the procedure easier, safer, and associated with faster healing.
Why Should Wisdom Teeth Be Removed?
Your dentist may recommend removal if:
- The tooth is impacted (stuck under the gum or bone)
- There is pain, infection, or swelling
- A cavity has formed in the wisdom tooth or adjacent tooth
- There is not enough space for proper eruption
- The tooth is growing sideways or at an angle
- Chewing, speaking, or cleaning the area becomes difficult
If left untreated, impacted wisdom teeth can cause significant damage, including jawbone changes, repeated infections, and even tooth loss.
Wisdom Tooth Pain: What Can You Do at Home?
If you’re experiencing soreness around your wisdom teeth, the first step is to see your dentist to rule out infection or decay. While waiting for your appointment, the following may help reduce discomfort:
Ibuprofen
A non-steroidal anti-inflammatory medication (NSAID) that reduces inflammation and provides significant relief from throbbing pain.
Salt-Water Rinse
Warm salt water helps reduce bacteria, soothe irritated gum tissue, and promote healing.
Topical Numbing Gel
Over-the-counter gels such as Orajel may help if the discomfort is coming from irritated gum tissue around the tooth.
Important:
Ignoring symptoms can allow infection to spread and may put nearby teeth at risk. Always seek assessment promptly.

What Is the Wisdom Tooth Removal Process?
Here’s what you can expect before, during, and after your extraction.
Before the Appointment
Your dentist will:
- Take digital X-rays
- Evaluate whether the teeth are impacted
- Assess root shape and proximity to nerves
- Discuss sedation or anesthetic options
- Review medical history and instructions
No special preparation is required unless sedation is planned.
During the Appointment
Wisdom tooth removal can be performed under local anesthesia, sedation, or general anesthesia depending on complexity and patient comfort.
The dentist or oral surgeon will:
- Numb the area to ensure comfort.
- Expose the tooth by gently opening the gum tissue if needed.
- Remove bone around the tooth if it is impacted.
- Section the tooth into smaller pieces if necessary for easier removal.
- Extract the tooth carefully.
- Clean and irrigate the area to prevent infection.
- Place stitches, if required, to aid healing.
A typical extraction takes 15–45 minutes, depending on difficulty and number of teeth removed.
After the Appointment
Mild swelling, stiffness, or soreness is expected for a few days. Most patients recover comfortably with:
- Ice packs
- Prescribed or OTC pain medication
- Soft foods
- Salt-water rinses (after 24 hours)
Avoid smoking, drinking through a straw, or vigorous rinsing, as these increase the risk of dry socket.
Your dentist will provide detailed instructions to ensure smooth healing.
Risks to Be Aware Of
Wisdom teeth removal is a common and safe procedure, but like all surgical treatments, it carries some risks:
- Swelling and discomfort
- Bleeding
- Infection
- Dry socket
- Damage to nearby teeth or fillings
- Temporary numbness (rare)
Following post-operative instructions significantly reduces these risks.
If you experience severe pain, persistent bleeding, fever, or unusual symptoms, contact your dentist immediately.
