Wisdom teeth, also known as third molars, typically emerge in your late teens or early twenties. While some people experience no issues, many others face problems due to impacted wisdom teeth — a condition where these molars do not fully erupt into the mouth.

At Whites Dental, with clinics in Waterloo (SE1) and Marble Arch (W2), we regularly help patients across London manage impacted wisdom teeth with expert care, advanced imaging, and personalised treatment.

If you’re experiencing discomfort, swelling, or tightness at the back of your mouth, this guide will help you understand what impacted wisdom teeth are, why they occur, and when to seek treatment.

⚠️ What Is An Impacted Wisdom Tooth?

An impacted wisdom tooth is one that fails to erupt properly due to lack of space, obstruction, or misalignment. This causes it to grow at an angle, partially emerge, or remain completely trapped under the gum or jawbone.

There are four types of impaction:

  1. Mesial impaction – when the wisdom tooth is angled forward, towards the front of the patients mouth
  2. Distal impaction – when the wisdom tooth is angled backward, towards the back of the patients mouth
  3. Vertical impaction – when the wisdom tooth fails to erupt at all – although it is aligned correctly
  4. Horizontal impaction – when the wisdom tooth is lying on its side and is pressing against the patients nearby molars

🧠 Impacted wisdom teeth often go unnoticed until they cause pain, infection, or complications — which is why early diagnosis is crucial.


🔍 What Causes Impacted Wisdom Teeth?

The main reason a person has impacted wisdom teeth is because of insufficient space in the jaw. Evolutionarily, our ancestors had larger jaws to accommodate more teeth, but modern jaws tend to be smaller.

Other contributing factors include:

  • Genetics (inherited jaw size or tooth alignment)
  • Delayed eruption or development
  • Misaligned adjacent teeth
  • Cysts or tumours blocking eruption

At Whites Dental London, we use digital X-rays and 3D scans at both our Waterloo and Marble Arch locations to identify impactions early and accurately.


😖 Common Symptoms Of Impacted Wisdom Teeth

Impacted wisdom teeth don’t always cause immediate pain. However, when symptoms do appear, they can include:

Pain and swelling

Persistent pain and discomfort is a common early sign, the pain is at the back of the patients mouth or jaw.

Gum infection (Pericoronitis)

Partially erupted teeth can trap bacteria and food, leading to swollen, red, or bleeding gums.

Jaw stiffness

Difficulty when the patient opens their mouth or difficulty while chewing can also signal underlying wisdom tooth impaction or/and inflammation.

Headaches or earaches

Pressure from impacted teeth can radiate pain into the head and ears.

Crowding or shifting teeth

Wisdom teeth may push against neighbouring molars, disrupting tooth alignment — especially if you’ve had orthodontic treatment.

Sinus pressure (upper wisdom teeth)

Impacted upper wisdom teeth can press against the sinuses, causing pressure or congestion.


🧪 How Are Impacted Wisdom Teeth Diagnosed?

At Whites Dental, our diagnosis process includes:

  • Detailed clinical examination
  • Digital X-rays to assess tooth position
  • Panoramic imaging for full-jaw visibility
  • 3D scans if the tooth is near critical structures like nerves or sinuses

Our experienced dentists in SE1 and W2 will explain the findings and recommend the most effective treatment plan based on your unique case.


🛠️ Treatment Options For Impacted Wisdom Teeth

The most common treatment (and also the most effective) is you have an impacted wisdom tooth is surgical extraction of the tooth. This is especially the case if the wisdom tooth is causing discomfort and pain, an infection or is damaging nearby tissue or teeth.

Simple monitoring

If the impacted tooth isn’t causing symptoms, we may recommend regular monitoring through X-rays and check-ups.

Minor gum surgery

For partially erupted teeth, we may perform a minor surgical exposure or gingivectomy to prevent repeated infections.

Surgical extraction

For wisdom teeth that are deeply impacted or are horizontal, a surgical extraction is usually recommended by the dentist. This involves:

  • Local anaesthetic (or sedation if needed)
  • Gum incision to access the tooth
  • Bone removal if the tooth is trapped
  • Tooth sectioning (if necessary)
  • Stitches and post-op care

💡 Surgical wisdom tooth removal is a common procedure at Whites Dental Waterloo and Marble Arch, and our clinicians ensure a pain-free experience using modern techniques.


🕒 Recovery & Aftercare

Recovery after an impacted tooth removal procedure can usually take between 7 and 10 days. This is of course dependent on the complexity of the extraction. Key recovery tips include:

  • Cold compress for swelling
  • Pain relief as prescribed
  • Soft foods for the first 2–3 days
  • Avoid smoking or drinking through straws to prevent dry socket
  • Maintain gentle oral care and hygiene (we suggest not brushing the extraction location for the first day after extraction)

Our team provides full aftercare instructions, and you’re always welcome to return to either of our central London clinics for follow-up care.

🤔 FAQs About Impacted Wisdom Teeth

❓ Can an impacted wisdom tooth fix itself?

No. Impacted teeth do not correct on their own and can worsen over time.

❓ Is surgery always necessary?

Not always. Some impacted teeth can be monitored if they’re not causing problems, but regular X-rays are needed.

❓ How painful is the surgery?

Most patients report mild discomfort post-op. With local anaesthetic or sedation, the procedure is pain-free.
