Benefits of keeping wisdom teeth: when removal isn’t always necessary
Wisdom teeth have a reputation for causing problems. Many people assume they will eventually need to be removed, often before they cause any symptoms. However, that is not always the case. In fact, there can be real benefits of keeping wisdom teeth, provided they are healthy, well positioned and properly monitored.At Winchester Avenue Dental Surgery, we regularly see patients who are unsure whether their wisdom teeth need to come out. Some arrive worried after hearing stories from friends, while others have been advised years ago that removal might be needed “one day”. The reality is that wisdom teeth should be assessed individually, not automatically removed.This guide explains the benefits of keeping wisdom teeth, when they can safely stay in place, when removal is recommended, and how regular dental check-ups help make the right decision at the right time.
What are wisdom teeth and why do we have them?
Wisdom teeth, also known as third molars, are the last adult teeth to develop. They usually emerge between the ages of 17 and 25, although some appear earlier or later, and some never emerge at all.Historically, wisdom teeth helped our ancestors chew coarse foods. As human diets and jaw sizes have changed, there is often less space for them. This lack of space is why wisdom teeth can sometimes cause issues. However, if there is enough room and the teeth erupt properly, they can function just like any other molar.Understanding this helps explain why the benefits of keeping wisdom teeth are often overlooked.
Do all wisdom teeth need to be removed?
No. This is one of the biggest myths in dentistry.Wisdom teeth do not need to be removed simply because they exist. Many people live their entire lives with healthy wisdom teeth that never cause a problem.At Winchester Avenue Dental Surgery, we follow evidence-based guidance. Removal is recommended only when there is a clear clinical reason, such as repeated infection, damage to neighbouring teeth or significant pain.If your wisdom teeth are healthy and easy to clean, keeping them can be the best option.The main benefits of keeping wisdom teeth
Let’s look at the genuine benefits of keeping wisdom teeth when they are problem-free.1. They can contribute to chewing function
When wisdom teeth are fully erupted and aligned, they can help with chewing, particularly tougher foods. They act just like other molars at the back of the mouth.For patients who already have missing teeth elsewhere, keeping healthy wisdom teeth can be especially useful.2. They help maintain jawbone strength
Teeth stimulate the jawbone when you chew. When teeth are removed, the bone in that area can gradually shrink over time.One of the lesser-known benefits of keeping wisdom teeth is that they continue to stimulate the bone, helping maintain jaw structure. While this may not be noticeable day to day, it contributes to long-term oral health.3. They can be useful if other teeth are lost
Healthy wisdom teeth can sometimes act as support teeth in the future. If a neighbouring molar is lost due to decay or fracture, a well-positioned wisdom tooth may help share biting forces or influence treatment planning.This is another reason dentists are cautious about unnecessary extractions.4. Avoiding unnecessary surgery
Tooth extraction is a safe and common procedure, but it is still surgery. Avoiding unnecessary removal means avoiding:- post-operative pain
- swelling
- infection risk
- dry socket
- time off work or study
5. Reduced risk of nerve complications
Lower wisdom teeth sit close to important nerves. Removing them carries a small risk of temporary or, rarely, permanent numbness.If a wisdom tooth is healthy and symptom-free, leaving it alone avoids this risk altogether.When keeping wisdom teeth is usually safe
Wisdom teeth are often best left in place when they:- are fully erupted
- are not causing pain
- are easy to clean
- are not damaging neighbouring teeth
- show no signs of decay or infection
- are monitored regularly
The role of dental check-ups in monitoring wisdom teeth
One of the most important factors in enjoying the benefits of keeping wisdom teeth is regular monitoring.During a routine check-up, your dentist will:- examine the wisdom teeth visually
- assess gum health around them
- check how easily they can be cleaned
- review X-rays if needed
- look for early signs of decay or infection
When wisdom teeth should be removed
Although there are benefits to keeping wisdom teeth, removal is sometimes the best option. Your dentist may recommend extraction if there is:- repeated infection (pericoronitis)
- severe pain or swelling
- decay that cannot be restored
- damage to the neighbouring tooth
- cyst formation
- gum disease around the wisdom tooth
- crowding that affects oral health
Why some people are told their wisdom teeth might cause problems later
You may have been told in the past that your wisdom teeth might need removal eventually. This does not always mean extraction is inevitable.Dentists sometimes identify wisdom teeth that are:- partially erupted
- difficult to clean
- positioned close to other teeth
Keeping wisdom teeth healthy: what you can do
If you are keeping your wisdom teeth, good oral hygiene is essential.Daily care tips
- Brush twice a day, paying attention to the back of the mouth
- Use a small-headed toothbrush
- Clean between teeth with floss or interdental brushes
- Rinse thoroughly after meals
Professional care
Regular dental visits help keep wisdom teeth healthy and spot problems early.You can book routine appointments through Winchester Avenue Dental Surgery.Wisdom teeth and age: does it matter?
Wisdom teeth are often easier to remove in younger adults, but that does not mean they should always be removed early “just in case”.If wisdom teeth are healthy at 25, they may remain healthy at 45 or 65 with proper care. Age alone is not a reason for removal.The decision is always based on current and predicted risk, not assumptions.Emergency symptoms you should not ignore
Even if you are enjoying the benefits of keeping wisdom teeth, certain symptoms require urgent attention:- severe pain
- swelling of the face or jaw
- difficulty opening the mouth
- fever
- bad taste or discharge
