Many adults with one or more missing teeth can be assessed for implants, but suitability is not automatic. The goal is to decide whether an implant-supported restoration can be placed, cleaned and maintained with an acceptable level of risk. Age alone is rarely the deciding factor; overall health, jaw growth, gums, bone, bite and expectations are more important.
What the assessment must answer
- Is the mouth healthy enough to begin treatment?
- Is there enough suitable bone in a safe position?
- Can the planned crown, bridge or denture fit the available space and bite?
- Are healing and maintenance risks understood and manageable?
- Would a bridge, denture or preservation of existing teeth be more appropriate?
Oral Health and Gum Condition
Active gum disease, uncontrolled decay and unresolved infection can increase complications and should usually be managed before implant placement. The assessment records gum inflammation, plaque control, pocketing, tooth mobility and bone levels around the remaining teeth.
An implant needs ongoing plaque control just as natural teeth do. If daily cleaning is difficult, the restoration may need a design that is easier to access or an alternative may be more maintainable.
Bone, Space and Bite
The clinician assesses whether enough bone is present at the correct position and whether nearby nerves, roots or the sinus limit placement. Routine dental imaging may be sufficient for initial evaluation; CBCT can be advised when three-dimensional detail is needed.
Bone quantity is only one part of planning. There must also be enough space for the crown or bridge, a suitable emergence through the gum and a bite that does not overload the restoration. Limited bone does not always rule out implants, but it may change the design or lead to discussion of bone grafting.
Medical History and Medicines
Medical conditions do not all have the same effect on implant treatment. The dental team considers stability and control of relevant conditions, healing ability and whether coordination with a physician is needed.
Disclose all prescription and non-prescription medicines, particularly anticoagulants, medicines that affect bone metabolism, immune-modifying treatment and previous or current cancer therapy. Also disclose allergies, bleeding problems, previous implant complications and any radiotherapy involving the jaws.
Smoking, Vaping and Healing
Tobacco exposure is associated with poorer wound healing and a higher risk of implant complications. The amount and duration of use, current gum condition and willingness to stop are discussed as part of risk assessment. Vaping should also be disclosed.
Stopping tobacco improves general and oral health. The clinic can explain how the planned procedure affects the recommended tobacco-free period, while long-term cessation provides the greatest benefit.
Age and Jaw Growth
Implants are generally delayed until jaw growth is complete because an integrated implant does not move with developing teeth and bone in the same way as a natural tooth. For older adults, chronological age alone does not decide suitability; health, anatomy, dexterity and ability to maintain the restoration matter more.
Factors That May Delay or Change the Plan
- Untreated gum disease, active infection or poor plaque control
- Insufficient bone without an acceptable grafting or alternative plan
- Uncontrolled medical conditions or a medicine-related risk requiring coordination
- Heavy smoking or unwillingness to follow healing and maintenance advice
- Insufficient restorative space or unfavourable bite forces
- Unrealistic expectations about timing, appearance, permanence or maintenance
Some factors are modifiable and may delay rather than permanently rule out treatment. Others may make a bridge or denture a more appropriate option.
What to Bring to an Implant Consultation
- A current list of medicines, supplements, allergies and medical diagnoses
- Relevant dental X-rays or reports if available
- Details of previous implants, grafts or complications
- Your priorities: fixed or removable, timing, appearance and maintenance
- Questions about who performs each stage, alternatives and follow-up care
After assessment, ask for a written plan that separates necessary treatment from optional enhancements and explains why the proposed design fits your findings.
