What Are Wisdom Teeth and Why Do We Have Them?
Wisdom teeth are the third and final set of molars at the very back of the mouth. They typically erupt between ages 17 and 25 — which is why they’re called “wisdom” teeth (the age of wisdom, in older terminology).
Most adults have four wisdom teeth: two upper and two lower. Some people have fewer due to genetics — about 25% of adults are missing one or more wisdom teeth from birth. A small percentage have additional supernumerary teeth.
Evolutionarily, wisdom teeth made sense when human jaws were larger and we needed extra grinding capacity for tough plant material and raw meat. Modern jaws are smaller — the result of softer diets over many generations — and often don’t have room for the third molars. This is why so many people need extractions.
Whether your wisdom teeth need to be removed depends on whether they have space to erupt properly, whether they’re causing problems, and whether they’re likely to cause problems in the future.
5 Signs You Need Wisdom Teeth Removed
These are the most common indicators that extraction is the right choice:
- Pain or pressure at the back of the jaw. Especially when the wisdom teeth are first erupting (late teens, early twenties) or when they become impacted and press against neighboring teeth or nerves.
- Recurring infection of the gum tissue (pericoronitis). The wisdom tooth is partially erupted, and food and bacteria get trapped under the flap of gum tissue covering it. This causes painful swelling, often accompanied by bad breath. It usually recurs every few months until the tooth is removed.
- Visible decay on the wisdom tooth or the second molar in front of it. Wisdom teeth are hard to reach with a toothbrush, and food traps easily between them and the molar in front. We frequently see decay on both teeth when wisdom teeth are partially erupted.
- Crowding of the front teeth. There’s still debate in dentistry about whether wisdom teeth actually push front teeth out of alignment, but in cases of post-orthodontic relapse, removing the wisdom teeth is sometimes recommended.
- Cysts or growths around the wisdom tooth. A wisdom tooth fully buried in the jawbone can occasionally develop a cyst (dentigerous cyst) around it that needs surgical removal. Routine X-rays catch this early.
If you have any of these symptoms — and especially if you’re under 25 — schedule an evaluation. Earlier extraction is usually easier and recovery is faster.
When You Can Keep Your Wisdom Teeth
Despite what you may have heard, not everyone needs their wisdom teeth removed. We routinely advise keeping them in cases where:
- They have fully erupted and are positioned like normal molars
- They can be brushed and flossed effectively
- They have no decay, infection, or gum problems
- They have an opposing tooth on the other arch to chew against
- X-rays show no cysts, no impaction of the adjacent molar, and no pathology
For these patients, the wisdom teeth are functional teeth and should be kept. Removal is unnecessary surgery.
The default advice 20 years ago was “everyone should have their wisdom teeth out by their early twenties.” Current evidence-based guidance is more nuanced: remove when there is a clear indication, otherwise leave them alone and monitor with periodic X-rays.
Dr. Elaine Perez-Gutierrez, DMD, who handles surgical extractions at our office, takes this approach: every wisdom tooth case is evaluated individually with X-rays, examination, and discussion of the patient’s history. We recommend extraction when it’s warranted and recommend monitoring when it’s not.
Cost of Wisdom Teeth Removal in Aventura
Wisdom teeth removal pricing depends on the complexity of each tooth’s extraction.
Simple extraction ($200–$400 per tooth):
- The wisdom tooth is fully erupted (visible in the mouth)
- The roots are not curved or wrapped around nerves
- Removal is done with standard dental forceps
- Local anesthesia only
- 15–30 minutes per tooth
Surgical extraction ($400–$800 per tooth):
- The wisdom tooth is impacted (still under the gum or partly under the bone)
- An incision in the gum is needed to access the tooth
- Bone may need to be removed around the tooth
- The tooth may need to be sectioned (cut into pieces) for removal
- 30–60 minutes per tooth
Full mouth extraction (all 4 wisdom teeth, $1,000–$2,500 total):
- Most patients have all four removed in a single appointment for efficiency
- Combined surgical time is 60–90 minutes
- IV sedation often used for patient comfort (+$400–$800)
Additional considerations:
- IV sedation: $400–$800 for the session
- Bone graft after extraction: $300–$600 per site (only if needed)
- Pre-surgery 3D CBCT scan: $150–$300 (recommended for complex impactions)
Insurance typically covers 50–80% of wisdom teeth extraction under “oral surgery” benefits. Annual maximums ($1,500–$2,500) may apply. We verify coverage before the procedure and provide a written estimate.
What to Expect During the Procedure
Step-by-step for a typical wisdom teeth extraction at our office:
Before the appointment:
- Eat a light meal 1–2 hours before if you’re getting local anesthesia only
- Fast for 6–8 hours if you’re getting IV sedation
- Arrange for someone to drive you home if sedation is involved
- Wear comfortable clothing
At the office:
- Vital signs are taken
- IV is started if applicable; sedation is administered
- Local anesthesia numbs the surgical area completely
- The wisdom tooth (or teeth) is removed — for impacted teeth, a small gum incision and removal of bone may be needed
- The socket is cleaned
- Sutures (stitches) are placed if needed — most modern stitches dissolve on their own in 7–10 days
- Gauze is placed over the socket; you bite down for 30–45 minutes to control bleeding
After the appointment:
- A friend or family member drives you home
- You’re given written post-op instructions, pain medication if needed, and antibiotics if there was infection
- Most patients rest for the remainder of the day
Day-by-Day Recovery Timeline
Realistic expectations for recovery after typical wisdom teeth extraction:
Day 1 (day of surgery):
- Stay home and rest
- Apply ice to the cheek (20 minutes on, 20 off) for the first 6 hours to reduce swelling
- Eat soft, cool foods only — yogurt, smoothies, applesauce, mashed potatoes
- Take prescribed pain medication; ibuprofen 600 mg every 6 hours works well for most
- Do not rinse, spit forcefully, or use a straw (any of these can dislodge the blood clot in the socket and cause dry socket)
- Some bleeding is normal for several hours; bite on gauze as instructed
Day 2:
- Swelling is at its peak — usually some visible facial swelling for 2–3 days
- Continue soft foods and pain medication
- Gentle warm salt-water rinses starting today — do not vigorously swish
- Most patients can return to desk work but should avoid physical exertion
Day 3–4:
- Swelling starts to decrease
- Pain noticeably better
- Begin adding semi-soft foods (eggs, pasta, soft fish)
- Continue salt water rinses 3–4 times per day
Day 5–7:
- Most pain resolved
- Swelling mostly gone
- Can return to most normal activities including light exercise
- Continue careful oral hygiene around the extraction sites
Day 7–14:
- Sutures dissolve or are removed at follow-up
- Full healing of the soft tissue
- Can return to all normal activities and foods
- Some patients still notice tenderness for a few more weeks
Day 14–30+:
- Bone underneath continues to heal and fill in
- Complete bone healing takes about 6 months but isn’t symptomatic
Do’s and Don’ts After Wisdom Teeth Surgery
Do:
- Take pain medication as directed — ibuprofen + acetaminophen alternating is often more effective than opioids
- Apply ice for the first 24 hours, then warm compresses for the next several days
- Eat soft, cool, non-spicy foods
- Sleep with your head slightly elevated for the first 2–3 nights
- Gently rinse with warm salt water starting day 2 (1/2 teaspoon salt in 8 oz warm water)
- Brush your teeth — just avoid the extraction sites for the first 24 hours
- Stay hydrated with water (no straws)
- Take time off — most patients need 2–3 days minimum before returning to work
Don’t:
- Don’t smoke for at least 72 hours — smoking is the #1 cause of dry socket
- Don’t drink alcohol for 72 hours (interacts with pain medication and slows healing)
- Don’t use a straw for 7 days
- Don’t spit or rinse forcefully for the first 24 hours
- Don’t poke at the extraction sites with your tongue or fingers
- Don’t eat hot foods on day 1 (heat increases bleeding)
- Don’t exercise vigorously for 3–5 days (raises blood pressure and can dislodge the clot)
- Don’t eat hard, crunchy, or sticky foods for at least 7–10 days (popcorn, nuts, chips, gum)
Dry socket (officially “alveolar osteitis”) is the most common complication, affecting 2–5% of extraction patients. It occurs when the blood clot in the socket dislodges before healing, exposing bone and nerves. It causes intense throbbing pain typically 3–5 days after surgery. It’s not dangerous but is very uncomfortable. We can treat it with a medicated dressing — call (305) 339-5701 if you suspect dry socket.
Frequently Asked Questions
Q1. How old should I be to have wisdom teeth removed?
The ideal age range is 17–25. At this age, the roots are not yet fully formed, the bone is less dense, and recovery is faster. Extraction in patients over 30 is still routine but tends to involve longer recovery.
Q2. How long do I need to take off work after wisdom teeth removal?
Most patients take 2–3 days off for office work, 5–7 days for physically demanding work. For desk jobs that aren’t urgent, returning on day 3 is comfortable for most. We provide a work-release letter if needed.
Q3. Will I get dry socket?
Dry socket affects 2–5% of all wisdom teeth extractions. The single biggest risk factor is smoking — if you smoke, your risk jumps to 12–15%. Following post-op instructions carefully — particularly avoiding straws, vigorous rinsing, and smoking — substantially reduces the risk.
Q4. Do I need to be put to sleep for wisdom teeth removal?
Not necessarily. Simple extractions of erupted wisdom teeth can be done with local anesthesia only — you’re awake but completely numb. For impacted wisdom teeth, especially all four at once, most patients prefer IV sedation, which makes the experience comfortable and the procedure pass quickly.
Q5. How much will my insurance cover for wisdom teeth removal?
Most PPO insurance plans cover 50–80% of wisdom teeth extraction under oral surgery benefits, subject to annual maximums ($1,500–$2,500). Simple extractions are covered at higher percentages than surgical extractions. We verify your specific coverage before the procedure.
Q6. Can my wisdom teeth grow back if removed?
No. Once a tooth is extracted with its roots, it cannot regrow. Very rarely, a small fragment of root may remain in the bone after a difficult extraction; if it’s not causing problems, it’s usually left in place and monitored. True regrowth doesn’t occur.
Q7. Is wisdom teeth removal safe?
Yes — it’s one of the most common surgical procedures in dentistry, with extremely low complication rates. The main risks are dry socket (2–5%), temporary nerve numbness (about 1%), and rare cases of permanent nerve damage in the lower jaw (less than 0.5%). Modern 3D imaging significantly reduces nerve injury risk by mapping the nerve location before surgery.
