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.
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 is not necessarily dishonest, but it is preventable with the right questions upfront.
You get a quote for dental implants. It sounds manageable. Then you come back for your scan appointment and the price goes up by GBP 1,000 or more.
This is one of the most common complaints in UK private dentistry. It is also mostly avoidable if you know what to ask before you commit.
Why initial quotes are often estimates, not prices
A consultation without imaging is a conversation about what you want, not a clinical assessment of what your jaw can support.
The dentist who quotes you before seeing your X-rays is giving you a planning estimate. They are saying: if your anatomy is typical and no preparatory work is needed, the cost will be approximately this. That is different from a fixed-price guarantee.
The problem is that many patients do not know this distinction exists. The quote feels like a price. It is actually a conditional estimate.
What the X-ray changes
Bone volume
Implants need bone. If you lost a tooth years ago, the bone in that area has been resorbing since extraction. A CBCT scan measures bone height, width, and density in three dimensions.
If the scan shows insufficient bone, the implant cannot be placed without bone grafting first. At Picasso, bone grafting adds GBP 116 to GBP 435 depending on the volume. At UK private clinics, the same procedure is typically priced at GBP 290 to GBP 726 or more.
This cannot be diagnosed from a clinical examination alone. It requires imaging.
Sinus proximity
Upper back teeth sit close to the maxillary sinuses. If the sinus floor has dropped or the bone height below the sinus is insufficient, a sinus lift is needed before an implant can be placed there.
A closed sinus lift adds GBP 203 at Picasso. An open sinus lift adds GBP 406. At UK clinics, the same procedures are often GBP 500 to GBP 1,500 per side.
A dental scan is the only way to assess sinus proximity accurately before surgery.
Hidden infection or root fragments
The OPG or CBCT scan sometimes reveals infection around a root tip, a fragment left from a previous extraction, or disease in a tooth that looked clinically sound.
If the infected area needs treatment before implant placement, that is additional cost. It is also better to know before surgery than during.
Nerve position
The inferior alveolar nerve runs through the lower jaw. If an implant site sits close to the nerve, shorter implants are needed, additional planning time is required, or the site is not suitable for a standard implant.
Again: a scan is the only reliable way to assess this.
Why some practices quote before imaging
Some UK practices (and some overseas clinics) give a headline quote at the first consultation to get a patient to commit. The low number creates a sense of affordability. The real price emerges later when imaging reveals the actual clinical picture.
This is not always bad faith. Some patients do not return after being told a scan is needed. A broad estimate keeps the conversation going. But the effect on patients is the same: a price that seemed settled turns out to be provisional.
Some practices do the opposite: they quote only after reviewing imaging. This is the more honest approach, and it is what both a good UK practice and a good overseas clinic should offer.
How to protect yourself
Ask for a post-imaging quote
Before committing to any treatment, ask: “Can we do the scan first and then confirm the price based on what the scan shows?”
A practice that insists on taking a deposit before imaging has a different incentive structure from a practice that reviews the scan before quoting.
Ask what is excluded
Ask the practice directly: “Does this quote assume I do not need bone grafting or a sinus lift? And if I do need them, what does that add?”
A good practice answers this clearly. If bone grafting is a realistic possibility in your case, the honest answer is: “Grafting adds GBP X to GBP Y. We cannot confirm until we see the scan.”
Ask if the price is fixed
Ask specifically whether the quoted price is a fixed-price guarantee or an estimate subject to revision. If it is subject to revision, ask what the maximum revision could be and what clinical circumstances would trigger it.
Get the quote in writing after imaging
A written itemised quote issued after the CBCT or OPG review is the most reliable baseline for your decision. It should name the implant brand, the material, and each clinical step, and it should confirm whether any preparatory procedures are included or separately charged.
How this works at Picasso Dental Clinic
Picasso asks UK patients to send their OPG or CBCT scan before issuing a quote. If images are not available, the scan is taken on arrival in Da Nang and the full itemised plan is confirmed before any treatment begins.
You are not committed to treatment before seeing the plan. The plan is in GBP, itemised by procedure, and signed off before the clinical team proceeds.
If the scan reveals that bone grafting or a sinus augmentation is needed, you are told before the surgical appointment, not on the day.
Bone grafting costs at Picasso:
| Graft type | Picasso price (GBP, May 2026) |
|---|---|
| Bone graft 0.25cc | GBP 116 |
| Bone graft 0.5cc | GBP 145 |
| Bone graft block | GBP 290 |
| Bio-Oss 0.5cc | GBP 232 |
| Bio-Oss block | GBP 435 |
| Sinus augmentation (closed) | GBP 203 |
| Sinus augmentation (open) | GBP 406 |
These are published prices, not estimates. They are included in your quote if the scan shows they are needed.
What to do if a UK quote changes after imaging
If a UK private quote increases substantially after imaging:
- Ask for the clinical reason in writing. What did the scan show that the consultation did not?
- Ask for an itemised revised quote showing each new line and its justification.
- Ask whether you can take a copy of your scan and get a second opinion before proceeding.
- If the new scope has changed significantly from what you were originally told, you are entitled to reconsider.
In UK private dentistry, you are not obligated to proceed with a practice once a quote has been revised. You own your X-rays and have the right to seek a second opinion.
