One of the most common questions we hear at Shine Dental Newington is some version of 'am I too far gone for implants?' It usually comes from someone whose teeth have been failing for years, whose gums have been fighting a losing battle, or who has worn dentures for so long they assume nothing else is possible. The encouraging reality is that All-on-X was developed precisely for situations like these — but suitability is individual, and it can only be confirmed by proper assessment. This guide explains who the treatment is designed for, what the assessment involves, and which factors genuinely influence candidacy.
What Situations Is All-on-X Designed For?
All-on-X — a full arch of fixed teeth supported by typically four to six implants per arch — is generally considered in three situations. The first is extensive tooth loss, where most or all teeth in an arch are already missing. The second is a failing dentition: teeth that are still present but loose, extensively decayed, repeatedly breaking, or compromised by advanced gum disease, where repairing them one by one is no longer a sensible investment. The third is long-term denture wearers who struggle with movement, sore spots, adhesives, or restricted eating, and who want a fixed alternative.
If any of these describes you, All-on-X is at least worth investigating. For a full explanation of how the treatment works, see what All-on-X dental implants are, and for the comparison with removable options, read All-on-X vs full dentures.
Do Your Remaining Teeth Need to Be Removed First?
No — and this surprises many people. You do not need to be already toothless to be a candidate. If your remaining teeth are not salvageable, their extraction is planned as a stage of the All-on-X treatment itself: consultation and CBCT scanning come first, then any extractions, then implant placement, followed by the provisional prosthesis and finally the definitive bridge. In many cases extractions and implant placement can be coordinated closely, so patients are not left without teeth during the process.
A history of gum disease also does not automatically rule you out. Periodontal disease is one of the most common reasons a full arch fails in the first place, and removing hopeless teeth eliminates the infected sites. What matters is that gum health is stabilised and that you commit to the hygiene and maintenance routine afterwards, because the tissues around implants also need to be kept healthy.
How Is Bone Volume Assessed — and How Much Do You Need?
Implants need bone to hold them, so bone volume is central to planning. When teeth are lost, the jawbone gradually resorbs, and long-term denture wearers in particular often have reduced ridge height. This is assessed with a CBCT scan — a three-dimensional cone beam image taken at your consultation that shows bone height, width, and density, along with structures that must be respected, such as nerves in the lower jaw and sinuses in the upper jaw.
The useful news is that All-on-X was designed with bone loss in mind. Implants can often be positioned and angled to make use of the denser bone that remains — commonly toward the front of the jaw — and the number of implants per arch is chosen to match what your anatomy supports, which we explain in how many implants All-on-X needs. Where bone is insufficient in specific areas, grafting or alternative implant positions may be planned. Very few patients are excluded on bone alone, but the plan — and therefore the quote — depends heavily on what the CBCT reveals, which is one of the factors that shape implant treatment costs.
Can You Have All-on-X if You Smoke or Have Diabetes?
These two questions come up constantly, and the factual answer is more nuanced than a yes or no.
Smoking does not automatically exclude you, but it is a genuine risk factor. Smoking reduces blood flow in the gums and is associated in the research with slower healing and higher rates of implant complications. Most clinicians will discuss reducing or stopping smoking, particularly around the surgical and healing phases, and will want you to understand the elevated risk before proceeding. It is a conversation about informed choice, not a lecture.
Diabetes is similar: well-controlled diabetes is generally compatible with implant treatment, and many patients with diabetes undergo All-on-X uneventfully. Poorly controlled blood sugar, however, impairs healing and increases infection risk, so your dentist may ask about your recent control and, where appropriate, liaise with your GP before surgery. Other medical factors — certain medications affecting bone, immune conditions, previous radiotherapy to the jaws — are also reviewed as part of your history. The purpose of these questions is planning, not gatekeeping.
Why Is Suitability Decided at a Consultation, Not Online?
Everything above describes tendencies, not verdicts. Two patients with the same story on paper can have completely different jaws on a CBCT scan, and no article, quiz, or photo assessment can substitute for one. A proper All-on-X consultation involves a clinical examination, three-dimensional imaging, a review of your medical history, and a discussion of what you actually want from treatment — fixed teeth are not the right answer for everyone, and an honest consultation should also tell you when a single or multiple implant solution, or indeed a well-made denture, would serve you better.
Dr. Jin-Ho Cho has spent 35+ years assessing exactly these cases, with 9,000+ implant fixtures placed across his career and a role as KOL for the DIO Implant System. That depth of experience matters most at the assessment stage, where judgement about bone, bite, and biology shapes everything that follows. After your consultation you receive a written itemised quote with item numbers, so you can check rebates with your health fund before making any decision.
