Impacted Wisdom Tooth Removal: Grade, Procedure, and Cost
Impaction grade determines procedure time, cost, and recovery. Grade 1 costs 2M VND and takes 15 minutes. Grade 4 costs 6M VND and takes up to 60 minutes. The same surgery runs $1,200 to $2,000 per tooth in the US.
Key Takeaways
- Impaction grade (1 to 4) is determined by your panoramic X-ray and drives the per-tooth price and procedure time.
- Grade 1 (soft tissue): 2M VND, 15-20 minutes. Grade 4 (horizontal or near-nerve): 6M VND, 45-60 minutes.
- Vietnam pricing is 70 to 90 percent below US or Australian private dental fees for the same surgical standard.
- Recovery is 5 to 7 days for most patients regardless of grade; higher grades mean more swelling in the first 2 days.
- Early removal (late teens to early 20s) is mechanically easier, cheaper, and heals faster.
- Grade 4 cases near the inferior alveolar nerve require cone-beam CT (3D imaging) before surgery to map nerve position.
The Four Impaction Grades Explained
An impacted wisdom tooth is one that cannot fully emerge through the gum, either because there is insufficient space in the jaw or because the tooth is angled incorrectly. The four-grade classification system is standard in oral surgery. Your grade is visible on a panoramic X-ray and determines the difficulty tier, price, and expected procedure time.
Grade 1: Soft tissue impaction
The tooth has erupted through the bone but is still partially covered by gum tissue. Often called "partially erupted." Frequently associated with pericoronitis (gum infection around the tooth flap). The simplest impaction type. Extraction involves making a small gum incision, sometimes lifting a flap, and removing the tooth. No bone removal is needed. Upper wisdom teeth at this grade are often the most straightforward cases in the clinic.
Grade 2: Partial bony impaction
The tooth crown is partially covered by bone in addition to gum tissue. Some bone removal is required to access the tooth. The tooth may still be at a relatively normal angle. Moderate difficulty. Panoramic X-ray is standard before proceeding.
Grade 3: Full bony impaction
The tooth is completely covered by bone. Significant bone removal is needed to access the crown. The tooth is often sectioned (cut into pieces) to remove it without forcing the socket. Considered difficult. Cone-beam CT is recommended if the angulation or depth is unclear on the panoramic X-ray.
Grade 4: Deeply impacted or horizontal
The tooth lies horizontally (parallel to the second molar), or it is very deep in the bone, or the roots are close to the inferior alveolar nerve. Highest difficulty. Cone-beam CT (3D imaging) is required at this grade to map the nerve position before surgery. In some cases, only the crown is removed and the root is left in place if it sits directly on the nerve (a technique called coronectomy), which reduces nerve-injury risk while still resolving the immediate problem.
The angulation factor
Within each grade, tooth angulation matters too. Mesioangular (tilted forward toward the second molar) is the most common and often easiest. Vertical and distoangular (tilted back) are intermediate. Horizontal is the hardest because the tooth must be sectioned before removal. Your panoramic X-ray shows both grade and angulation.
Upper vs lower
Upper wisdom teeth are usually easier than lower at the same grade because the upper bone is less dense and the inferior alveolar nerve is not directly underneath. A Grade 3 upper extraction is typically faster and causes less post-op swelling than a Grade 3 lower. Pricing reflects this in the difficulty assessment at consultation.
Impaction Grade, Cost, and Procedure Time
Per-tooth pricing at Picasso. Chair time is for the extraction itself; add 30 minutes for check-in, anaesthesia, X-rays, and post-op briefing.
| Grade | Picasso price | Chair time | Typical recovery | Imaging |
|---|---|---|---|---|
| Erupted (no impaction) | 2,000,000 VND / ~$80 USD | 10 to 15 min | 3 to 5 days | Standard X-ray |
| Grade 1 (soft tissue) | 2,000,000 VND / ~$80 USD | 15 to 20 min | 3 to 5 days | Standard X-ray |
| Grade 2 (partial bony) | 4,000,000 VND / ~$160 USD | 25 to 35 min | 5 to 7 days | Panoramic X-ray |
| Grade 3 (full bony) | 5,000,000 VND / ~$200 USD | 35 to 50 min | 5 to 7 days | Panoramic X-ray; 3D if angle unclear |
| Grade 4 (horizontal or near-nerve) | 6,000,000 VND / ~$240 USD | 45 to 60 min | 7 to 10 days | Cone-beam CT required, +600K VND |
| All four wisdom teeth (mixed grades, typical) | 12,000,000 to 18,000,000 VND | 90 to 120 min total | 5 to 7 days for the set | Panoramic; CBCT if any Grade 4 |
Sedation is available at the larger branches for anxious patients and adds 2 to 5M VND per session. Grades are confirmed at the consultation X-ray; the written quote is given before any work begins.
Vietnam vs US vs Australia: Per-Tooth Surgical Cost
The cost difference between Vietnam and Western countries is not a quality compromise. The same cone-beam CT scanners, surgical kits, and anaesthesia protocols are used. The cost difference is overhead: Vietnam clinic rent, staff costs, and insurance overhead are a fraction of US or Australian equivalents.
| Per tooth, impacted | Picasso (Vietnam) | Australia (oral surgeon) | US (oral surgeon) |
|---|---|---|---|
| Grade 1 (soft tissue) | 2M VND / ~$80 USD | AUD $400 to $700 / ~$260 to $460 USD | $300 to $600 |
| Grade 2 (partial bony) | 4M VND / ~$160 USD | AUD $600 to $1,200 / ~$390 to $790 USD | $400 to $900 |
| Grade 3 (full bony) | 5M VND / ~$200 USD | AUD $1,000 to $1,800 / ~$660 to $1,180 USD | $700 to $1,500 |
| Grade 4 (near-nerve or horizontal) | 6M VND / ~$240 USD | AUD $1,500 to $2,500 / ~$985 to $1,640 USD | $1,200 to $2,000 |
| All 4 impacted (avg case) | 12M to 18M VND / ~$480 to $720 USD | AUD $3,500 to $7,000 / ~$2,300 to $4,600 USD | $3,000 to $7,000 |
| Cone-beam CT (when needed) | 600K VND / ~$24 USD | AUD $250 to $400 / ~$165 to $260 USD | $300 to $500 |
For an all-four impacted case, international patients typically save USD $2,500 to $6,500 by travelling to Vietnam, which more than covers a 10 to 14 day trip including flights and accommodation.

The Procedure Step by Step
For a typical Grade 2 to 3 impacted lower wisdom tooth. Higher grades have additional steps; lower grades skip some.
Anaesthesia and exposure (10 to 15 minutes)
Local anaesthetic is injected. Numbness is tested before proceeding. A small incision is made in the gum over the impacted tooth and a flap is reflected to expose the bone and tooth crown. For Grade 1, the flap is small or just a gum trim.
Bone removal and tooth sectioning (15 to 30 minutes)
For Grade 2 to 4, a small amount of bone is removed with a surgical bur to access the tooth. The tooth is often sectioned (cut into 2 or 3 pieces) to remove it without forcing the socket. You feel pressure and vibration but no pain. For Grade 4, this is the longest step.
Removal, cleaning, and closure (10 to 15 minutes)
Each section of the tooth is removed individually. The socket is irrigated and inspected. Stitches close the gum flap (usually dissolving stitches, 3 to 5 per tooth). Gauze is placed to control bleeding. Post-op instructions are given in writing. You wait 15 to 20 minutes to confirm bleeding is controlled before leaving.
Recovery After Impacted Extraction
5 to 7 days for most patients. Detailed post-op care reduces complication risk by roughly half.
First 24 hours
Bite gently on gauze for 30 to 45 minutes after the procedure. Ice pack on the outside of the cheek 20 minutes on, 20 minutes off for the first 6 to 12 hours. Take ibuprofen 400 to 600 mg plus paracetamol 1 g together for pain. No straws. No spitting. No vigorous rinsing. Soft food only (yoghurt, smoothie, soup). Head elevated on a pillow for sleep.
Days 2 to 3
Swelling peaks at day 2 to 3. Bruising may appear on the cheek or jaw; it looks worse than it feels. Salt-water rinse 2 to 3 times daily (starting day 2). Continue soft food. Continue painkillers as needed. Most patients still uncomfortable enough to take a sick day.
Days 4 to 5
Clear day-over-day improvement starts. Add warm compress to outside of cheek to help swelling resolve. Diet expands to soft-normal (pasta, rice, fish). Stop painkillers when discomfort drops below 2/10. Continue salt-water rinse.
Days 6 to 7
Most patients resume work, school, and normal activity. Light exercise is fine. Some bruising may still be visible but pain is essentially gone. Continue gentle hygiene around the extraction sites.
Week 2 to 4
Stitches dissolve (or are removed if non-dissolving) by day 7 to 14. Sockets are visibly closing. Resume all normal eating. Full bone-level healing continues silently for 4 to 6 weeks. No restrictions.
Risk Profile: What to Know Before Consenting
All complications are uncommon and most are manageable with prompt treatment.
| Complication | Incidence | Management |
|---|---|---|
| Dry socket (alveolar osteitis) | 2 to 5% | Medicated dressing at the clinic, 5-minute visit, resolves in 3 to 5 days |
| Temporary lip or tongue numbness (lower) | 2 to 5% | Usually resolves within weeks to months |
| Permanent nerve injury (lower) | Less than 1% | Rare; CBCT for Grade 4 reduces this further |
| Sinus involvement (upper) | Less than 1% | Usually self-resolves; antibiotic if symptoms develop |
| Post-extraction infection | 2 to 5% | Antibiotic course (amoxicillin 5 to 7 days) |
| Bleeding requiring additional control | Less than 1% | Sutures or pressure pack; rarely needs ER |
| Adjacent tooth damage | Less than 1% | Very rare with experienced surgeon |
| Jaw fracture (very thin lower jaw) | Less than 0.1% | Rare; identified at consultation by panoramic X-ray |

Frequently Asked Questions
What is an impacted wisdom tooth?
An impacted wisdom tooth is one that cannot fully emerge through the gum, either because there is not enough space in the jaw or because the tooth is angled incorrectly. There are four impaction grades: Grade 1 (soft tissue impaction, gum covers part of the tooth), Grade 2 (partial bony impaction, some bone still around the tooth), Grade 3 (full bony impaction, bone covers most of the tooth), and Grade 4 (deeply impacted, tooth lies horizontally or very deep). Higher grades take longer to extract and cost more.
How much does impacted wisdom tooth extraction cost at Picasso?
Cost depends on impaction grade. Grade 1 (soft tissue): 2,000,000 VND (~$80 USD). Grade 2 (partial bony, moderate difficulty): 4,000,000 VND (~$160 USD). Grade 3 (full bony, difficult): 5,000,000 VND (~$200 USD). Grade 4 (near nerve or horizontally impacted): 6,000,000 VND (~$240 USD). Includes examination, X-ray, local anaesthetic, the extraction, and post-op review. Cone-beam CT (recommended for Grade 4) adds 600,000 VND.
How does Vietnam pricing compare to the US for impacted extraction?
US oral surgeon fees for impacted extraction: simple bony impaction $400 to $700 per tooth, complex bony or near-nerve $1,200 to $2,000 per tooth, all four impacted $3,000 to $7,000 total. Australia: AUD $500 to $2,000 per impacted tooth, $2,500 to $6,000 for all four. Picasso pricing is 70 to 90 percent lower for the same surgical standard. International patient savings on all-four impacted cases: $2,000 to $5,000 USD even after flights and accommodation.
How long does impacted wisdom tooth removal take?
Per-tooth chair time: Grade 1 (soft tissue) 15 to 20 minutes, Grade 2 (partial bony) 25 to 35 minutes, Grade 3 (full bony) 35 to 50 minutes, Grade 4 (horizontal or deeply impacted) 45 to 60 minutes. Add 30 minutes for check-in, anaesthesia, X-rays, and post-op briefing. For all four impacted teeth in one session, total appointment is 90 to 150 minutes. See all four at once vs staged for the full comparison.
Why do impacted teeth need to be removed?
Four main reasons: 1) Pericoronitis (recurrent gum infection around partially erupted tooth). 2) Damage to the adjacent second molar from pressure. 3) Cyst or tumour formation around the impacted tooth (uncommon but serious). 4) Crowding or pushing the rest of the teeth out of alignment, sometimes undoing previous orthodontic work. Even asymptomatic impacted teeth are usually recommended for removal in the late teens or early 20s when healing is faster.
What is the recovery like after impacted extraction?
5 to 7 days for most patients. Day 1 to 2: peak swelling and discomfort, soft food only, ibuprofen plus paracetamol. Days 3 to 5: swelling subsides, eating expands, comfort returns. Days 6 to 7: most patients resume work. Higher impaction grades (3 and 4) often have more swelling and slightly slower initial recovery, but the timeline is similar overall. Stitches dissolve in 7 to 14 days; non-dissolving stitches are removed at the 1-week post-op review.
What are the risks of impacted wisdom tooth extraction?
Risks are low when performed by an experienced team but include: dry socket (lost blood clot, 2 to 5 percent incidence), nerve injury for lower wisdom teeth close to the inferior alveolar nerve (less than 1 percent permanent, 2 to 5 percent temporary numbness or tingling), sinus involvement for upper wisdom teeth (less than 1 percent), infection (less than 5 percent), and bleeding requiring additional control (rare). Cone-beam CT for Grade 4 cases reduces nerve injury risk by precisely mapping the nerve position.
Should I have impacted wisdom teeth removed even if they do not hurt?
For most patients in late teens or early 20s with impacted wisdom teeth visible on X-ray, yes. Prophylactic removal at this age has the fastest recovery, lowest complication rate, and prevents future problems (pericoronitis, second-molar damage, cyst formation, orthodontic relapse). For patients over 30 with asymptomatic impacted teeth, the decision is more nuanced; watchful waiting with annual X-rays is sometimes appropriate. Discuss at consultation.
