Dental implants can provide a fixed replacement for missing teeth, but like all surgical and restorative procedures, they carry potential risks and limitations. Outcomes vary from person to person.

Surgical Risks: As with any surgery, there may be bleeding, swelling, pain, infection, or bruising following the procedure.
Implant Failure: In some cases, the implant may not integrate with the bone (osseointegration failure), which may require removal or replacement.
Bone and Gum Changes: Over time, bone or gum tissue may change around the implant, affecting stability or appearance.
Nerve or Sinus Involvement: In rare cases, surgery may impact nearby nerves, leading to temporary or permanent numbness/tingling, or may affect the sinus area in upper jaw placements.
Adjacent Teeth or Structures: There is a small risk of damage to neighbouring teeth or surrounding tissues during placement.
Healing Variability: Healing times differ. Factors such as smoking, general health, or oral hygiene can affect implant success.
Mechanical Risks: Crowns, bridges, or dentures attached to implants may chip, loosen, or require replacement over time.
Maintenance Requirements: Implants require the same (or higher) level of oral hygiene and professional care as natural teeth. Poor maintenance can lead to peri-implantitis (gum infection and bone loss around the implant).
Longevity: While implants can be long-lasting, they are not guaranteed to last a lifetime and may require future maintenance or replacement.

Not every patient is suitable for dental implants. A full consultation with a registered dental practitioner is required to assess risks and determine whether veneers are appropriate for your individual situation.
