28 Aug Wisdom Tooth Removal: Signs You Might Need It
Wisdom teeth do not automatically need removing. Treatment is usually considered when a wisdom tooth is causing repeated gum infections, ongoing pain or swelling, tooth decay, an abscess, gum disease, a cyst, or damage to the tooth beside it. A dentist will normally examine the area and may take an X-ray before deciding whether removal, monitoring or another treatment is best. Wisdom teeth are the final adult molars to develop at the very back of the mouth. They usually start appearing during the late teenage years or early twenties, although problems can develop later in life too.
Some come through normally and never cause trouble. Others become partly trapped beneath the gum or grow at an angle because there is not enough room. These are known as “impacted wisdom teeth”. The important point is that being impacted alone does not mean the tooth needs surgery. The decision should be based on whether it is causing disease or a significant ongoing problem.
1. Repeated Pain and Swelling Around the Wisdom Tooth
Pain at the back of the mouth is one of the most obvious reasons people visit a dentist about their wisdom teeth.You may notice tenderness behind the second molar, discomfort when chewing or swelling around the gum. Pain can sometimes spread towards the jaw or ear. A wisdom tooth that is simply erupting can cause temporary discomfort. Pain that repeatedly returns, becomes severe or is accompanied by swelling deserves a dental examination. Your dentist will need to identify whether the discomfort actually comes from the wisdom tooth. Jaw-joint problems, muscle pain and other teeth can produce symptoms in the same area.
2. Repeated Gum Infections
A partially erupted wisdom tooth may leave a flap of gum covering part of the tooth. Food and bacteria can collect underneath it, making the area difficult to clean.
This can lead to pericoronitis, an inflammation or infection of the gum around a partly erupted tooth. Symptoms may include soreness, swelling, an unpleasant taste and difficulty opening your mouth comfortably.It is one of the most common reasons for wisdom tooth treatment. Guy’s and St Thomas’ reports that pericoronitis is present in up to 6 in 10 patients they see with wisdom-tooth problems.
However, one mild episode does not necessarily mean the tooth must come out. NICE guidance says a first episode of pericoronitis, unless particularly severe, is generally not by itself an indication for surgery. Repeated episodes are a stronger reason to consider removal.
3. Food Keeps Getting Trapped
A partly erupted or badly positioned wisdom tooth can create an awkward space where food repeatedly becomes trapped.This may seem like a minor annoyance, but the location can be extremely difficult to brush and floss properly. Persistent food packing encourages plaque accumulation and can eventually contribute to decay and gum inflammation. More importantly, the damage is not always limited to the wisdom tooth. The neighbouring second molar can also develop decay or periodontal problems. This is one reason dentists assess the tooth in front of the wisdom tooth as carefully as the wisdom tooth itself.
4. Tooth Decay Has Developed
Wisdom teeth sit far back in the mouth, where effective brushing can be difficult. If a tooth is only partly visible or positioned at an angle, cleaning becomes even harder. Decay can therefore develop in the wisdom tooth itself. Removal may be considered when the decay cannot be predictably restored.A badly positioned wisdom tooth can also contribute to decay on the back surface of the neighbouring second molar. NICE specifically includes unrestorable decay and disease affecting an adjacent tooth among recognised reasons for considering removal. Do not rely on pain as your only warning sign. Decay can progress without causing obvious symptoms until it becomes deeper.
5. You Develop an Abscess
A dental abscess is a collection of infection that may develop around a badly decayed or infected wisdom tooth.Symptoms can include intense toothache, gum or facial swelling, an unpleasant taste and feeling generally unwell. An abscess needs dental assessment. Antibiotics may sometimes be needed when infection is spreading or causing systemic symptoms, but they do not permanently remove the source of a dental infection. If facial swelling is increasing rapidly or you have difficulty swallowing or breathing, seek urgent medical help.
6. The Wisdom Tooth Is Damaging the Tooth Next to It
This is one of the most important signs that competitor articles often underplay. An impacted wisdom tooth can press against or create an unhealthy area beside the second molar. Over time, this can contribute to decay, gum disease or, less commonly, resorption where part of the neighbouring tooth’s structure is lost. University Hospitals Plymouth lists decay in the tooth in front and periodontal disease affecting the neighbouring molar among established reasons for wisdom tooth removal. Protecting a healthy second molar can sometimes be a stronger reason for treatment than symptoms from the wisdom tooth itself.
7. A Cyst Develops Around the Tooth
Wisdom teeth develop inside a small sac. Occasionally, fluid can collect around an unerupted tooth and form a cyst.Cysts associated with wisdom teeth are uncommon. Guy’s and St Thomas’ reports them in fewer than 1 in 100 patients they see with wisdom-tooth problems.
They can nevertheless enlarge and affect surrounding bone or teeth. Because a cyst may initially cause few symptoms, it can sometimes be identified on an X-ray rather than because the patient feels pain.
Does an Impacted Wisdom Tooth Always Need Removing?
No.This is perhaps the most important fact to understand. NICE recommends against routinely removing healthy, pathology-free impacted wisdom teeth. There is no reliable evidence that removing every symptom-free impacted tooth provides a health benefit, while surgery itself carries risks.
If a wisdom tooth is healthy and causes no problems, your dentist will usually monitor it during routine check-ups.Interestingly, NICE is currently developing updated guidance on prophylactic removal of impacted third molars, but the existing guidance remains the relevant published recommendation while that work continues.
How Does a Dentist Decide?
The decision should involve more than asking whether the tooth hurts. Your dentist will examine the wisdom tooth, surrounding gum and neighbouring teeth. An X-ray can show its angle, how deeply it is impacted, whether decay or other disease is present, and how its roots relate to surrounding structures.
For lower wisdom teeth, the relationship between the roots and important nerves can affect the surgical plan. In selected high-risk cases, a specialist may discuss coronectomy, where the crown is removed while roots close to the nerve are deliberately left in place.That option is another detail many basic wisdom-tooth guides fail to mention.
What Happens During Wisdom Tooth Removal?
Many wisdom teeth can be removed using local anaesthetic, so the area is numb while you remain awake. More difficult cases may require sedation or, less commonly, general anaesthetic. The dentist or oral surgeon may need to open the gum and sometimes divide the tooth into smaller pieces before removing it. Dissolvable stitches may then be placed. The NHS says the procedure often takes only a few minutes and normally no more than around 40 minutes, although complexity varies. Swelling, soreness and some difficulty opening the mouth can occur afterwards. Possible complications include infection, dry socket, bleeding and temporary or, less commonly, longer-lasting nerve symptoms.
Wisdom Tooth Services in Salisbury
Patients experiencing wisdom-tooth pain in Salisbury can start with an examination at a local dental practice. Depending on the position and complexity of the tooth, services may include dental X-rays, management of infection, routine extraction or referral to a clinician with appropriate oral-surgery experience or a hospital oral and maxillofacial department. Wisdom tooth removal can also be provided through the NHS when clinically necessary. If you have recurring swelling, pain, difficulty opening your mouth or signs of infection, arranging an assessment early can help determine whether the tooth should be treated, removed or simply monitored.
Final Thoughts
Wisdom tooth removal is useful when a tooth is repeatedly infected, decayed, damaging nearby structures or associated with another dental problem. It is not something everyone needs simply because their wisdom teeth are impacted.
If symptoms keep returning, arrange a dental examination rather than repeatedly treating pain at home. An examination and X-ray can show what is happening beneath the gum and help you make an informed decision.
FAQs
How do I know if my wisdom tooth needs to be removed?
Repeated infections, persistent pain, swelling, decay, an abscess, gum disease, cyst formation or damage to the neighbouring tooth are common reasons for considering removal.
Do all impacted wisdom teeth need to come out?
No. NICE recommends that healthy impacted wisdom teeth without disease should not routinely be removed.
Can wisdom teeth damage other teeth?
Yes. Poorly positioned wisdom teeth can contribute to decay, gum disease or other damage affecting the neighbouring second molar.
Is wisdom tooth removal painful?
Local anaesthetic prevents pain during the procedure. Soreness and swelling are common afterwards but normally improve as healing progresses.
Can wisdom teeth cause infection?
Yes. Partially erupted wisdom teeth can develop pericoronitis because bacteria and food become trapped beneath the surrounding gum.
