Quick Summary
Wisdom teeth usually appear between ages 17 and 25. Not every one needs to come out, but teeth that are impacted, repeatedly infected, decayed or harming the neighbouring molar usually do. With an X-ray, local anaesthesia and clear aftercare, removal is a routine procedure and most people are back to normal within about a week.
What Are Wisdom Teeth and Why Do They Cause Problems?
Wisdom teeth, or third molars, are the last teeth to arrive, usually somewhere between the ages of 17 and 25. Most people are born with four: two on the top and two on the bottom, right at the very back of the mouth.
The trouble is space. Many modern jaws are simply too small to hold them. A wisdom tooth may come through only partly, sit at an angle, or stay trapped beneath the gum and bone. Dentists call this an impacted tooth. A partly erupted tooth also creates a small flap of gum where food and bacteria collect, and that is where most wisdom tooth infections begin.
Six Signs Your Wisdom Tooth Needs Attention
Wisdom teeth do not always announce themselves loudly. Watch for these common warning signs:
- Dull or throbbing pain at the back of the jaw, which may spread to the ear, temple or neck.
- A red, swollen or tender gum flap over a partly erupted tooth. This is called pericoronitis and it tends to flare up again and again.
- A bad taste or persistent bad breath coming from the back of your mouth, sometimes with a little pus.
- Stiffness or difficulty opening your mouth fully.
- Food that keeps getting stuck behind your last molar, however carefully you brush.
- Decay or gum trouble in the tooth in front of it, because the wisdom tooth makes that area very hard to clean.
Do not wait if you notice this
Facial swelling, fever, difficulty swallowing or trouble breathing alongside tooth pain can point to a spreading infection. Get seen the same day. If breathing or swallowing is difficult, go to a hospital emergency department straight away.
Does Every Wisdom Tooth Need to Be Removed?
No. Some wisdom teeth come in fully, sit in a proper bite and are easy to keep clean. Those can safely stay. The decision depends on your X-ray and your symptoms, not on your age alone.
| Situation | What dentists usually advise |
|---|---|
| Fully erupted, healthy and easy to clean | Keep it and monitor at regular check-ups |
| Partly erupted with repeated gum infections | Removal is usually recommended |
| Impacted and painful, or pressing on the next molar | Removal is usually recommended |
| Badly decayed and difficult to restore | Removal is usually recommended |
| Impacted but no symptoms | Case by case: watch with periodic X-rays or plan removal |
If you are unsure which group you fall into, a single X-ray and a short examination will answer it. You can also read more about this treatment on our wisdom teeth service page.
How Impacted Wisdom Teeth Are Classified
Your dentist will describe the angle of your tooth on the X-ray because it affects how the extraction is planned. The usual patterns are:
- Mesial (angled forward): the tooth leans towards the second molar. This is the most common pattern and can trap food and decay the neighbouring tooth.
- Vertical: the tooth is upright but may be stuck under the gum or bone.
- Horizontal: the tooth lies on its side, pressing against the second molar.
- Distal (angled backward): the tooth leans towards the back of the jaw and is often harder to reach.
How Wisdom Tooth Removal Works
A good extraction is planned, unhurried and explained to you beforehand. Here is what the process typically looks like.
Assessment and X-ray
We examine the area and study an X-ray to see the tooth angle, roots and how close the tooth sits to the nerve.
Local anaesthesia
The area is fully numbed. You stay awake and comfortable, and you should feel pressure but not pain.
Gentle extraction
If needed, a small gum opening is made and the tooth is removed, sometimes in sections. Stitches are placed when required.
Aftercare briefing
You leave with gauze, clear written instructions and any medicines your dentist prescribes.

What Recovery Looks Like, Day by Day
Everyone heals a little differently, and a lower impacted tooth usually takes longer than an upper one. This is a general guide.
| When | What to expect |
|---|---|
| Day 1 | Bite gently on the gauze, rest, and use a cold pack on the cheek. A little oozing of blood-tinged saliva is normal. |
| Days 2 to 3 | Swelling and jaw stiffness are often at their peak. Stay with soft, cool or lukewarm food. |
| Days 4 to 7 | Discomfort eases steadily. Gentle warm salt-water rinses help. Dissolvable stitches loosen on their own. |
| 1 to 2 weeks | Most people are eating normally again. The socket keeps healing under the gum for several weeks. |
Aftercare: What to Do and What to Avoid
- Do: bite on clean gauze for 30 to 45 minutes after the procedure and apply a cold pack in short intervals on the first day.
- Do: eat soft foods such as curd rice, khichdi, mashed banana, buttermilk and soups, and sleep with your head slightly raised.
- Do: take medicines exactly as prescribed, and start gentle salt-water rinses after the first 24 hours.
- Avoid: vigorous rinsing or spitting on day one, drinking through a straw, smoking, tobacco and alcohol.
- Avoid: hot, spicy or crunchy food for the first few days, and poking the area with your tongue or fingers.
Dry socket: what it is and when to call us
A dry socket happens when the blood clot in the extraction site is lost too early. The typical sign is pain that gets worse a few days after removal, sometimes with a bad taste. It is uncomfortable but very treatable. Smoking raises the risk. Call the clinic if your pain is increasing rather than easing.
Three Wisdom Tooth Myths, Cleared Up
- “It will change the shape of my face.” Removing a wisdom tooth does not change your jawline or your smile.
- “I will be in agony for weeks.” With local anaesthesia and proper aftercare, most people manage well with the prescribed medicines and settle within days.
- “Wait until it hurts.” Waiting often means treating an infection first and a harder extraction later. Removing a problem tooth earlier is usually simpler.
Wisdom Tooth Care at Dr. Barun's Dental Centre, Velachery
At our Velachery clinic we start with a proper assessment and explain what your X-ray shows in plain language. You will know whether the tooth needs to come out, how the procedure will go and what it is likely to involve before we begin. If your problem is not just the wisdom tooth, our team also treats related concerns such as bleeding gums and cavities in the same visit plan.
Frequently Asked Questions
The area is numbed with local anaesthesia, so you should feel pressure and movement but not sharp pain during the procedure. Some soreness afterwards is normal and is managed with the medicines your dentist prescribes.
It depends on the position of the tooth. A straightforward erupted tooth can be quick, while a deeply impacted tooth takes longer. Your dentist can give you a realistic estimate once they have seen your X-ray.
Many people take a day or two off, especially after a lower wisdom tooth removal, when swelling and stiffness are common. Desk work is usually easier to return to than physical work.
Not necessarily. Only the teeth that are causing or likely to cause problems need to go. Sometimes it makes sense to treat both sides of the jaw in one visit, and sometimes it is better to stage it. Your dentist will advise after examining you.
The cost varies with how the tooth is positioned and how complex the extraction is. We give you a clear estimate after the examination and X-ray, so there are no surprises.
Every surgical procedure has some. Common ones are swelling, bruising and dry socket. Rarely, lower wisdom teeth sit close to a nerve, which is why we assess the X-ray carefully first.
