Signs, Symptoms & When to See a Dentist in London
Wisdom teeth are the last adult teeth to emerge, usually appearing between the ages of 17 and 25. For some people, they grow in without any problems. For others, they can cause pain, swelling, infections, overcrowding, and damage to nearby teeth.
If you’ve been wondering whether your wisdom teeth need removing, this guide explains the most common signs, what to expect, and when to book an appointment with a dentist.

What Are Wisdom Teeth?
Wisdom teeth are the third molars located at the very back of your mouth. Most adults have four wisdom teeth, although some people may have fewer or none at all.
Because they erupt later in life, there is often not enough room in the jaw for them to grow properly. This can lead to impacted wisdom teeth, where the tooth becomes trapped beneath the gum or grows at an awkward angle.
Common Signs Your Wisdom Teeth May Need Removing
1. Persistent Pain at the Back of the Mouth
One of the most common symptoms is ongoing pain or discomfort near the back molars. This pain may come and go initially but can gradually become more severe.
You may notice:
- Jaw pain
- Toothache near the back teeth
- Pain when chewing
- Headaches caused by jaw pressure
2. Swollen or Bleeding Gums
Impacted wisdom teeth can irritate the surrounding gum tissue, leading to:
- Redness
- Swelling
- Tender gums
- Bleeding while brushing
This condition, known as pericoronitis, can become painful and may require urgent dental treatment.
3. Difficulty Opening Your Mouth
If your wisdom teeth are infected or impacted, inflammation can spread to the jaw muscles, making it difficult to:
- Open your mouth fully
- Chew comfortably
- Speak normally
This may also be accompanied by swelling around the cheeks or jawline.
4. Repeated Infections
Partially erupted wisdom teeth create small gaps where bacteria and food particles become trapped. This can lead to repeated infections and bad breath.
Common symptoms include:
- Unpleasant taste in the mouth
- Persistent bad breath
- Pus around the gums
- Swelling around the tooth
5. Crowding or Shifting Teeth
Wisdom teeth can push against neighbouring teeth if there isn’t enough space in the mouth. This pressure may cause:
- Crooked teeth
- Shifting after orthodontic treatment
- Bite problems
- Difficulty cleaning between teeth
Many patients seek wisdom tooth removal to protect their smile alignment.
6. Tooth Decay or Gum Disease
Because wisdom teeth are difficult to clean properly, they are more vulnerable to:
- Cavities
- Tooth decay
- Gum disease
- Infections affecting nearby molars
Dentists often recommend removal if the tooth cannot be cleaned effectively.
Do All Wisdom Teeth Need Removing?
No — not everyone needs wisdom tooth extraction.
A dentist may recommend keeping your wisdom teeth if they are:
- Healthy
- Fully erupted
- Properly aligned
- Easy to clean
- Not causing pain or damage
Regular dental check-ups and X-rays help monitor wisdom teeth before problems develop.
How Dentists Diagnose Wisdom Tooth Problems
During your consultation, a dentist will usually:
- Examine your mouth and gums
- Check for swelling or infection
- Take digital X-rays
- Assess tooth positioning and jaw space
X-rays are especially important because impacted wisdom teeth may not be visible above the gumline.
At London City Smiles, patients benefit from advanced dental technology and experienced clinicians who can determine whether removal is necessary.
What Happens During Wisdom Tooth Removal?
Wisdom tooth extraction is a routine dental procedure.
Depending on the complexity, treatment may involve:
- Local anaesthetic
- Sedation options
- Surgical extraction for impacted teeth
Most patients recover within a few days, although healing can vary depending on the position of the tooth.
Wisdom Tooth Recovery Tips
After extraction, dentists usually recommend:
- Resting for 24–48 hours
- Avoiding smoking
- Eating soft foods
- Keeping the area clean
- Avoiding vigorous rinsing
Following aftercare instructions carefully helps reduce the risk of complications such as dry socket.
When to See a Dentist About Wisdom Teeth
You should book a dental appointment if you experience:
- Ongoing tooth pain
- Swollen gums
- Jaw stiffness
- Facial swelling
- Difficulty chewing
- Repeated mouth infections
Early assessment can prevent more serious dental problems later on.
