Why cheap dental quotes change after the X-ray
Initial dental quotes often rise after a CBCT scan or OPG reveals bone loss, infection, or anatomy that changes the treatment plan. This article explains why it happens and how to protect yourself — for Australian patients considering treatment in Vietnam or at home.
A dental quote given before reviewing your X-rays is a starting estimate, not a clinical price. When a CBCT scan or OPG reveals insufficient bone volume, hidden infection, sinus proximity, or the need for additional extractions, the treatment scope changes and so does the cost. This happens at reputable clinics in Australia and Vietnam alike — the difference is whether the revised plan is explained clearly before treatment starts.
Why photo-based quotes are always estimates
When you send dental photos and request a quote from any clinic — in Australia or Vietnam — the clinician reviewing them can see:
- The visible tooth surface and colour
- Approximate tooth position and alignment
- Visible gaps from missing teeth
- Approximate gum position
They cannot see from photos:
- Bone volume and density beneath the gum
- The location of the inferior alveolar nerve (lower jaw)
- Sinus floor height (upper jaw)
- Hidden decay under existing restorations
- Root canal status
- Periapical infection
- Bone deficiency from previous extraction
All of these affect treatment planning and cost. The only way to see them is a CBCT scan or, for some assessments, an OPG X-ray.
This is why every reputable clinic — Picasso included — states clearly that quotes are provisional pending the Day 1 CBCT assessment.
The five most common reasons quotes rise after the X-ray
1. Bone deficiency — requires grafting
The most common reason an implant quote rises. The CBCT shows that the bone at the implant site is insufficient in height, width, or density for safe placement.
What changes: a bone graft is required before or at the time of implant placement.
- Picasso bone graft cost: AUD 441–1,655 depending on volume and material
- Australian bone graft cost: AUD 1,500–4,000
How to reduce the risk: send an existing OPG or CBCT to the clinic before you book flights. If significant bone loss is visible on the OPG, Picasso can flag this before you commit.
2. Sinus proximity — requires sinus lift
For upper posterior implants (premolars and molars), the CBCT may show that the maxillary sinus floor is very close to the intended implant site — leaving insufficient bone above for safe placement.
What changes: a sinus augmentation (sinus lift) is performed to raise the sinus floor and create bone volume.
- Picasso sinus lift: AUD 1,272–2,483
- Australian sinus lift: AUD 2,000–5,000
3. Hidden infection — requires treatment first
An OPG or CBCT may reveal a periapical abscess or failing root canal at or near the implant site. Active infection is a contraindication for implant placement — the infection must be treated first.
What changes: root canal treatment or extraction added before implant placement. This may also affect the trip timeline.
4. Tooth unsuitable for veneer — crown required instead
A photo veneer quote assumes the teeth have adequate enamel structure for bonded veneer placement. If the clinical examination or X-ray reveals:
- Large existing filling that has consumed most of the enamel
- Root canal treated tooth that needs full coverage for structural protection
- Cracked tooth
Then a crown (not veneer) is the appropriate restoration.
Emax crown at Picasso: AUD 566 vs Emax veneer: AUD 510 — a small per-tooth difference, but worth knowing in advance.
5. More teeth affected than anticipated
X-rays may reveal decay or bone loss on teeth adjacent to the planned treatment — teeth that appeared fine in photos. If these teeth require treatment before or alongside the planned work, the scope increases.
Red flags — when a quote change is NOT legitimate
| Red flag | What it looks like |
|---|---|
| No CBCT taken | Quote rises based on palpation alone, without diagnostic imaging |
| No itemised breakdown | “The new total is AUD X” with no explanation of what changed |
| Pressure to decide same day | “This price is only valid today” |
| Upgrade pressure without clinical basis | “We recommend the Straumann implant” without CBCT evidence requiring it |
| Unlisted procedures added | Fluoride treatment, whitening, nightguard added to an implant appointment |
If you encounter these patterns at any clinic — Australian or overseas — ask for written documentation of the clinical basis for the change, and take time to review before proceeding.
How Picasso handles quote variations
At Picasso, the Day 1 CBCT assessment is the diagnostic baseline. If the findings differ from the photo-based quote:
- The treating dentist explains the CBCT findings in English, showing the patient the images
- A revised itemised plan is produced in writing
- The patient is given time to review — no same-day pressure
- If the revised total exceeds the patient’s budget, the scope can be renegotiated: fewer implants, a lower-tier brand, staging treatment across two years
No procedure begins until the patient signs the revised consent form.
How to prepare — before you book flights
- Send your existing OPG or CBCT with your quote request — the earlier obvious issues are identified, the less surprising the Day 1 assessment
- Ask your Australian dentist for their clinical assessment before travelling: “Do you see any bone loss on my OPG that might affect implant planning?”
- Include a contingency — if your implant budget is AUD 1,500, budget AUD 2,000–2,500 in case a small graft is needed
- Ask the clinic in writing: “Will you tell me and show me the CBCT findings before any treatment begins, and provide a revised itemised quote if the scope changes?”
