Not every wisdom tooth needs to be removed.
Wisdom teeth are the final set of molars at the very back of your mouth. Some grow into a useful position and cause no problems at all. Others become impacted, partially erupt, trap food or develop decay and infection.
So, if you have been told that you have an impacted wisdom tooth, or you have started experiencing pain at the back of your mouth, you may be wondering:
“Do I actually need my wisdom tooth removed?”
The answer depends on the individual tooth, its position, your symptoms and whether there is evidence of disease or damage.
At Centre of Dental Excellence in Stanmore, we can assess wisdom teeth and discuss whether monitoring, preventive care or removal may be appropriate.
What Are Wisdom Teeth?
Wisdom teeth are also known as third molars.
They are the last permanent teeth to develop and typically emerge during late adolescence or early adulthood, although the timing varies between individuals. Some people develop fewer than four wisdom teeth, while some do not develop them at all.
A wisdom tooth can:
- Erupt normally
- Remain completely underneath the gum
- Partially erupt
- Become impacted because there is insufficient space
- Grow at an unusual angle
- Remain present without causing any symptoms
An impacted wisdom tooth is one that cannot fully erupt into its normal position because of a lack of space, obstruction or its position within the jaw.
Do All Wisdom Teeth Need to Be Removed?
No.
A wisdom tooth that is healthy, disease-free and functioning normally does not automatically need to be removed.
NICE guidance recommends that pathology-free impacted wisdom teeth should not routinely be removed as a preventative measure. Instead, they can generally be managed as part of normal dental care and monitored where appropriate.
This is important because wisdom tooth removal is a surgical procedure and, like other forms of surgery, has potential risks.
The decision should therefore be based on the condition of the tooth and the individual circumstances rather than simply the fact that a wisdom tooth is impacted.
Why Do Some Wisdom Teeth Need to Be Removed?
A wisdom tooth may require removal when it is causing a significant problem or there is evidence of disease or damage.
Potential reasons can include:
- Repeated infections around the tooth
- Significant tooth decay
- Gum disease affecting the wisdom tooth or neighbouring tooth
- A dental abscess
- Damage to an adjacent tooth
- A wisdom tooth that cannot be restored
- Certain cystic or other pathological changes
- A tooth that has fractured
- Other circumstances where the tooth interferes with planned dental or jaw surgery
NICE specifically identifies several forms of pathology that can justify surgical removal of an impacted wisdom tooth.
9 Signs Your Wisdom Tooth May Be a Problem
1. Pain at the Back of Your Mouth
One of the most obvious signs that a wisdom tooth may be causing trouble is pain at the very back of your mouth.
You may notice discomfort:
- Around one particular wisdom tooth
- When chewing
- When opening your mouth
- Around the gum behind your second molar
- That comes and goes
- That becomes worse during an episode of inflammation
Pain does not automatically mean the tooth needs to be extracted, but it is a reason to have it assessed.
3. You Keep Getting Infections Around the Tooth
Have you had the same wisdom tooth become swollen or painful more than once?
Repeated episodes can be an important sign that the tooth is difficult to keep clean or is not erupting into a healthy position.
While a single episode of inflammation does not automatically mean extraction is necessary, recurrent problems warrant assessment.
Your dentist can determine whether the tooth can be managed conservatively or whether removal should be considered.
5. The Wisdom Tooth Is Causing Tooth Decay
Wisdom teeth can develop decay just like other teeth.
In some cases, their position makes them particularly difficult to clean or treat.
Decay can also affect the second molar next to the wisdom tooth.
This is important because the problem may not always feel as though it is coming from the wisdom tooth itself.
A dental examination can help identify which tooth is actually causing the symptoms.
7. You Have Swelling, a Bad Taste or Signs of Infection
Swelling around a wisdom tooth can indicate inflammation or infection.
You may also experience:
- A bad taste in your mouth
- Bad breath
- Pus around the gum
- Increasing pain
- Difficulty opening your mouth
- Swelling around the jaw
These symptoms should not simply be ignored.
If you have significant swelling, severe pain, fever or difficulty swallowing or breathing, seek urgent dental or medical advice as appropriate.
9. Your Wisdom Tooth Is Causing Ongoing Dental Problems
Sometimes the issue is not one isolated symptom.
You may have a combination of:
- Repeated pain
- Recurring swelling
- Decay
- Gum problems
- Food trapping
- Difficulty cleaning
- Problems affecting the adjacent tooth
When problems keep coming back, it may be appropriate to discuss whether keeping the wisdom tooth is still the best option for your individual situation.
2. Swollen or Tender Gum Around the Wisdom Tooth
If a wisdom tooth has only partially erupted, a flap of gum can remain around part of the tooth.
Food debris and bacteria can collect in this area, potentially causing inflammation or infection.
You may notice:
- Redness
- Swelling
- Tenderness
- Bleeding
- Difficulty cleaning the area
- An unpleasant taste or smell
This inflammation around a partially erupted wisdom tooth is commonly known as pericoronitis.
If symptoms are severe or keep returning, your dentist may need to consider whether the wisdom tooth should be removed.
NICE notes that recurrent episodes of pericoronitis can be a reason to consider surgical removal.
4. You Have Difficulty Cleaning Around the Wisdom Tooth
Some wisdom teeth are positioned so far back or at such an angle that brushing and flossing around them becomes difficult.
This can allow plaque and food debris to accumulate.
Over time, this may contribute to:
- Tooth decay
- Gum inflammation
- Bad breath
- Infection
- Problems affecting the neighbouring molar
The fact that a wisdom tooth is difficult to clean does not, by itself, automatically mean it needs to be removed. However, your dentist can assess whether its position is creating an ongoing oral-health problem.
6. Your Wisdom Tooth Is Affecting the Tooth Next to It
An impacted or incorrectly positioned wisdom tooth can sometimes create problems for the neighbouring second molar.
Depending on its position, it may make cleaning difficult or contribute to decay or gum problems affecting the adjacent tooth.
This is one reason dentists may use dental X-rays when assessing wisdom teeth.
An X-ray can help show:
The position of the wisdom tooth
Whether it is impacted
The angle of the tooth
Its relationship with neighbouring teeth
The surrounding bone
Whether there are signs of associated disease
Your dentist can determine whether imaging is clinically appropriate as part of your assessment.
8. The Wisdom Tooth Is Impacted
An impacted wisdom tooth is one that has not fully erupted into its normal position.
It may be:
- Completely underneath the gum
- Partially erupted
- Angled towards the neighbouring tooth
- Positioned horizontally
- Blocked because there is not enough room
But remember:
Impacted does not automatically mean “needs to be removed.”
NICE guidance specifically distinguishes between impacted wisdom teeth that are disease-free and those associated with pathology.
Your dentist can monitor an asymptomatic tooth when appropriate rather than recommending removal simply because it is impacted.
What Is Pericoronitis?
Pericoronitis is inflammation around the gum tissue surrounding a partially erupted tooth, often a wisdom tooth.
Because part of the tooth may remain covered by gum, the area can be difficult to clean.
Symptoms can include:
- Pain
- Swollen gum
- Redness
- Bad taste
- Bad breath
- Discomfort when chewing
- Difficulty opening the mouth
The severity and recurrence of these episodes matter when deciding how the tooth should be managed.
NICE states that a first episode of pericoronitis that is not particularly severe would not generally, by itself, be considered an indication for surgery, while repeated episodes may support considering removal.
Can a Wisdom Tooth Be Left Alone?
Yes.
If your wisdom tooth is healthy and not causing problems, your dentist may recommend monitoring rather than removal.
This can mean checking the tooth during routine dental examinations and maintaining good oral hygiene around the area.
The decision can change over time.
A wisdom tooth that causes no problems today may develop decay, gum inflammation or another issue later, which is why regular dental reviews remain important.
Does an Impacted Wisdom Tooth Always Cause Problems?
No.
Some impacted wisdom teeth remain problem-free.
An X-ray may show that a wisdom tooth is impacted, but that finding alone does not mean it must be removed.
The important questions are:
Is the tooth causing disease?
Is it damaging another tooth?
Can it be maintained and monitored safely?
What are the potential benefits and risks of removing it?
These are the types of questions your dentist can discuss with you when deciding how to manage your wisdom tooth.
What Happens During a Wisdom Tooth Assessment?
Your dentist will usually begin by asking about your symptoms and examining your mouth.
They may look at:
- The wisdom tooth itself
- The surrounding gum
- The neighbouring teeth
- Your bite
- Signs of decay
- Signs of infection
- How much of the tooth has erupted
Depending on your symptoms and clinical findings, an X-ray may also be recommended to assess the position of the wisdom tooth and its relationship with nearby structures.
The findings can then be used to discuss your treatment options.
Does Wisdom Tooth Removal Hurt?
Wisdom tooth removal is a surgical dental procedure, so it is normal for patients to have questions about discomfort and recovery.
The type and complexity of removal varies significantly.
A straightforward erupted wisdom tooth can be very different from a deeply impacted tooth requiring surgical removal.
Your dentist or oral surgery team should explain the procedure, expected recovery and relevant risks before treatment.
NICE guidance highlights that decisions about dental surgery should involve discussion of risks and treatment options with the patient.
What Are the Risks of Wisdom Tooth Removal?
Like any surgical procedure, wisdom tooth removal has potential complications.
Depending on the tooth and procedure, these can include:
- Pain and swelling
- Infection
- Delayed healing
- Bleeding
- Damage to nearby structures
- Nerve-related complications in certain lower wisdom tooth cases
The risks depend on factors such as the tooth’s position and the complexity of the procedure.
This is another reason why removing every wisdom tooth simply because it is present is not appropriate.
The decision should be based on an individual assessment.
Should I Have My Wisdom Teeth Removed Before They Cause Problems?
This is a common question.
There is an important difference between:
“My wisdom tooth is present.”
and
“My wisdom tooth is causing disease or a significant problem.”
NICE guidance does not recommend routine preventive removal of pathology-free impacted wisdom teeth.
However, your own circumstances still matter.
If a wisdom tooth is repeatedly becoming infected, has significant decay, is damaging an adjacent tooth or is associated with another pathological problem, removal may be considered.
Your dentist can explain the findings and discuss the available options with you.
When Should I See a Dentist About a Wisdom Tooth?
Arrange a dental assessment if you have:
🦷 Pain at the back of your mouth
🔴 Swollen or bleeding gum around a wisdom tooth
😣 Pain when chewing
🫧 Swelling around the jaw
🦠 A bad taste or signs of infection
😮 Difficulty opening your mouth
🪥 Difficulty keeping the area clean
⚠️ Repeated episodes of pain or swelling
If you develop significant swelling of the mouth, lips, throat or neck, particularly if it affects breathing, swallowing or speaking, seek urgent medical attention.

Final Thoughts: Do All Wisdom Teeth Need Removing?
No, not every wisdom tooth needs to be removed.
A healthy, disease-free wisdom tooth may simply need to be monitored.
However, persistent pain, repeated infections, swelling, decay, gum problems or damage to neighbouring teeth can indicate that a wisdom tooth needs closer assessment and potentially treatment.
If you are unsure whether your wisdom tooth is a problem, the best place to start is with a dental examination.
