Wisdom teeth are the final set of molars to develop, usually appearing between the ages of 17 and 25. While some people have enough space in their mouth for wisdom teeth to grow normally, others experience problems because the teeth become impacted, infected, or difficult to clean.
Not everyone needs their wisdom teeth removed. However, when they begin causing pain, damage, infection, or other dental problems, removal may be recommended. Understanding the signs and timing can help you make an informed decision about your oral health.
What Are Wisdom Teeth?
Wisdom teeth are the third molars located at the very back of the mouth. Most people have four wisdom teeth, two on the upper jaw and two on the lower jaw but some people may have fewer or none.
These teeth were more useful to our ancestors, who had larger jaws and diets that required more chewing. Today, many people do not have enough room for wisdom teeth to grow properly.
When there is insufficient space, a wisdom tooth may become impacted or grow at an unusual angle.
When Should Wisdom Teeth Be Removed?
There is no specific age at which everyone should have their wisdom teeth removed. Dentists generally recommend removal when there is a clear risk of current or future problems.
Common reasons for wisdom tooth removal include:
1. Pain or Discomfort
Pain at the back of your mouth is one of the most common signs that a wisdom tooth may be causing problems. You may experience pain while chewing, opening your mouth, or touching the area around the tooth.
Persistent or recurring pain should be assessed by a dentist rather than ignored.
2. Impacted Wisdom Teeth
A wisdom tooth is impacted when it cannot fully emerge through the gum because there is not enough space or it is growing in the wrong direction.
An impacted tooth may grow:
- Towards the neighbouring tooth
- Towards the back of the mouth
- Horizontally
- Partially through the gum
- At an unusual angle
Impacted wisdom teeth can sometimes cause pain, swelling and infection.
3. Repeated Gum Infections
Partially erupted wisdom teeth can create a small pocket between the tooth and gum. Food particles and bacteria can become trapped in this area, making it difficult to clean properly.
This can lead to a condition called pericoronitis, which may cause:
- Swollen gums
- Redness
- Pain
- Bad breath
- Difficulty opening the mouth
- An unpleasant taste
If infections keep returning, removing the wisdom tooth may be recommended.
4. Damage to Nearby Teeth
A wisdom tooth growing at an angle can put pressure on the second molar next to it. Over time, this can contribute to decay, gum problems or damage to the neighbouring tooth.
Your dentist may use dental X-rays to determine the position of the wisdom tooth and check whether it is affecting nearby teeth.
5. Tooth Decay
Wisdom teeth are located at the back of the mouth, which can make them difficult to brush and floss effectively.
If a wisdom tooth develops significant decay and cannot be easily restored, removal may be considered.
6. Cysts or Other Problems
In some cases, an impacted wisdom tooth can be associated with a cyst or other changes around the tooth. Although these problems are not common, dental X-rays can help identify abnormalities that may not be visible during a routine examination.
Do All Wisdom Teeth Need to Be Removed?
No. If a wisdom tooth has erupted properly, is healthy, can be cleaned effectively and is not causing problems, your dentist may recommend keeping it.
Some people live their entire lives with their wisdom teeth without experiencing significant complications.
Your dentist can monitor the teeth during regular check-ups and use X-rays when appropriate to assess their position and condition.
Is It Better to Remove Wisdom Teeth Early?
The best time for removal varies from person to person.
In some cases, dentists may recommend removing problematic wisdom teeth earlier rather than waiting until they cause repeated infections or significant damage. Younger patients may sometimes have easier extractions and recovery, but age alone does not determine whether removal is necessary.
The decision should be based on factors such as tooth position, symptoms, oral health, potential complications and your dentist’s assessment.
What Happens During Wisdom Tooth Removal?
Before removal, your dentist will examine your mouth and may take an X-ray to understand the position of the tooth and its roots.
Depending on the complexity of the extraction, wisdom teeth can generally be removed using local anaesthetic, while more complex cases may require additional forms of sedation or anaesthesia.
During the procedure, the dentist removes the tooth and provides instructions for caring for the area while it heals.
Recovery varies depending on the number and position of the teeth removed and the complexity of the procedure.
What Are the Signs You Should See a Dentist?
You should arrange a dental examination if you experience:
- Persistent pain at the back of your mouth
- Swollen or bleeding gums
- Difficulty opening your mouth
- Facial swelling
- Bad breath that keeps returning
- Difficulty chewing
- Repeated infections around a wisdom tooth
- Pain or sensitivity near a neighbouring molar
Severe swelling, difficulty breathing or difficulty swallowing can require urgent medical attention.
Final Thoughts
Wisdom teeth do not always need to be removed, but impacted, infected, decayed or problematic teeth may require extraction to protect your oral health. Regular dental check-ups and appropriate X-rays can help identify potential problems before they become more serious.
