Wisdom teeth removal is one of the most common dental procedures performed on young adults, and it is also one of the most anxiety-provoking. The combination of surgery, recovery time, and plenty of dramatic stories from friends and family tends to build it up as something far worse than it actually is.
This guide walks through exactly what happens before, during, and after wisdom teeth removal so you know what to expect at every step.
Do You Actually Need Your Wisdom Teeth Removed?
Not everyone does. Wisdom teeth, formally called third molars, erupt between the ages of 17 and 25. Some people never develop them at all. Some develop them and they come in straight, fully erupted, and easy to clean. In those cases, removal may not be necessary.
Removal is typically recommended when wisdom teeth are:
- Impacted, meaning they are blocked from erupting fully and remain partially or fully under the gum or in the jawbone
- Partially erupted, creating a pocket where bacteria accumulate and infection is likely
- Crowding neighboring teeth, pushing against the second molar and causing damage or misalignment
- Causing recurrent infection or cysts around the follicle surrounding the tooth
- Impossible to clean properly, leading to decay on the wisdom tooth or the tooth in front of it
If your wisdom teeth are fully erupted, easy to reach with a toothbrush, and causing no problems, your dentist may simply monitor them at regular checkups rather than recommending removal. At Destiny Dental, we take dental X-rays during your dental exam to assess wisdom tooth position and discuss the right approach for your situation.
Before the Procedure: What to Do
The consultation. Before any extraction, your dentist will take a panoramic X-ray or a series of periapical X-rays to assess the position of the wisdom teeth, their root development, and their relationship to nearby structures including the inferior alveolar nerve in the lower jaw. This imaging tells your dentist how straightforward or complex each extraction will be.
Understanding what type of extraction you need. There are two main categories:
A *simple extraction* is used when the tooth has fully erupted above the gum line. The dentist loosens the tooth with a dental instrument and removes it. This is the same type of extraction used for any other tooth.
A *surgical extraction* is required when the tooth is partially or fully impacted. The dentist makes a small incision in the gum, may remove a small amount of bone overlying the tooth, and may section the tooth into pieces to remove it more easily. This sounds more involved than it feels, because the area is fully numb throughout.
The night before. If you are having your wisdom teeth removed under local anesthesia only, you can eat normally the day before. If sedation is planned, your dentist will give you specific fasting instructions, typically nothing to eat or drink for several hours before the procedure.
Bring someone with you. Even if you are having local anesthesia only, having a driver is advisable for the day of the procedure. If any sedation is used, a driver is required.
During the Procedure: What Actually Happens
The first thing your dentist does is numb the area completely with local anesthesia. You will feel a small pinch from the needle, followed by a spreading numbness. For most patients, this is the most uncomfortable part of the entire appointment.
Once the area is numb, you may feel pressure, movement, and vibration during the extraction, but not pain. The distinction between pressure and pain is important. Pressure is normal and expected. If you feel sharp pain at any point, raise your hand to signal the dentist. More anesthetic can always be administered.
For a simple extraction, the process typically takes a few minutes per tooth. For a surgical extraction involving an impacted tooth, it may take 15 to 30 minutes per tooth. Having all four wisdom teeth removed in one appointment is common and often preferable since you only go through the recovery once.
How long does wisdom teeth removal take overall? For most patients having all four removed under local anesthesia, the appointment takes between one and two hours from the time you sit in the chair to when you leave, including time for the anesthetic to take effect and for the sites to be dressed with gauze.
After the Procedure: The Recovery Timeline
Recovery from wisdom teeth removal follows a predictable pattern for most patients. Knowing what is normal at each stage helps you avoid unnecessary worry and catch anything that genuinely needs attention.
The First 24 Hours
Some bleeding from the extraction sites is normal for the first several hours. Bite firmly on the gauze your dentist places at the end of the appointment and change it as directed. Avoid rinsing, spitting forcefully, or using a straw. All of these actions create suction in the mouth that can dislodge the blood clot forming in the socket.
That clot is essential. It is the foundation for healing. Losing it prematurely leads to dry socket, one of the more painful complications of wisdom teeth removal.
Swelling begins within a few hours of the procedure and typically peaks at around 48 to 72 hours. Use an ice pack wrapped in a cloth against the outside of your face for the first day, 20 minutes on and 20 minutes off. After 48 hours, switching to gentle warmth helps more than cold.
Eat soft foods only: yogurt, applesauce, mashed potatoes, scrambled eggs, soup. Avoid anything hot for the first 24 hours.
Take pain medication as directed by your dentist, beginning before the anesthesia wears off rather than waiting until you are already in discomfort. Over-the-counter ibuprofen is typically effective for wisdom teeth removal recovery pain when taken consistently.
Days 2 to 4
Swelling and discomfort should begin improving by day 3. If they are getting worse rather than better after this point, contact your dentist.
Begin rinsing gently with warm salt water after 24 hours, about half a teaspoon of salt in a glass of warm water. Do this gently several times a day, particularly after eating. This helps keep the sites clean without disturbing the clot.
Most patients who have desk or school-based work return within two to three days. Physical activity and anything strenuous should be avoided for at least five days, as increased blood pressure can reopen the extraction sites.
The First Week
Stitches, if placed, are typically dissolvable and will disappear on their own within a week to ten days. Some bleeding or pink-tinged saliva is normal; significant fresh bleeding that does not stop with direct pressure is not and warrants a call to your dentist.
By the end of the first week, most patients are eating more normally and feeling close to their usual selves.
When to Call Your Dentist
Contact your dentist if you experience:
- Severe, worsening pain beginning two to four days after the procedure (this is the hallmark of dry socket)
- Significant swelling that is spreading or accompanied by fever
- Difficulty opening your mouth that is not improving
- Numbness that has not resolved within a few hours of the procedure and persists into the following day
What Is Dry Socket and How Do You Avoid It?
Dry socket, or alveolar osteitis, occurs when the blood clot that forms in the extraction socket is dislodged or dissolves before the site has healed, leaving the bone exposed. It is uncomfortable but not dangerous and is treatable.
The pain typically begins two to four days after the extraction, is more intense than normal post-operative soreness, and may radiate into the ear or jaw. Your dentist will clean the site and pack it with a medicated dressing to protect the exposed bone while it heals.
To reduce your risk of dry socket: avoid straws, do not smoke for at least 48 to 72 hours, avoid forceful rinsing or spitting in the first 24 hours, and follow your dentist’s instructions precisely.
Are Wisdom Teeth Covered Under CDCP?
Extractions, including surgical extractions of impacted teeth, are covered under the Canadian Dental Care Plan for eligible patients. Coverage depends on your income level and the government fee schedule. For patients covered under CDCP, your out-of-pocket cost may be significantly reduced or eliminated. Visit our CDCP page for more information on how your coverage applies.
Frequently Asked Questions
Is wisdom teeth removal painful?
The procedure itself is not painful because the area is completely numb. Post-operative soreness is normal for three to five days and is typically manageable with over-the-counter pain relief.
How long does wisdom teeth removal recovery take?
Most patients feel significantly better within three to five days. Complete healing of the socket takes several weeks, but most people return to normal activities within a week.
Can I eat normally after wisdom teeth extraction?
Not immediately. Stick to soft foods for the first three to five days, avoiding anything hard, crunchy, or chewy. Hot foods and drinks should also be avoided for the first 24 hours.
What happens if I leave impacted wisdom teeth in?
Impacted wisdom teeth that are not causing symptoms can sometimes be monitored. However, leaving truly problematic impacted teeth in place risks infection, cysts, damage to the adjacent tooth, and increasingly complex surgery as root development continues and the jaw bone becomes denser with age.
How long does wisdom teeth removal take if all four are removed?
For most patients, removing all four wisdom teeth in one appointment takes between one and two hours, though this varies depending on the complexity of the impactions.
Conclusion
Wisdom teeth removal is straightforward for most patients. The procedure is done under effective local anesthesia, the discomfort during and after is manageable, and most people return to normal within a week. The key to a smooth recovery is following aftercare instructions carefully, particularly in the first 24 hours when the blood clot is most vulnerable.
