SafetyThe risks, stated plainly
No surgery is risk-free, and a chin implant — short and reversible as it is — is still surgery. These are the four things that actually matter, and how each is minimised.
Infection
The mouth carries bacteria, so the intraoral route is often quoted as carrying a somewhat higher theoretical infection risk than the under-chin route. It is managed in practice with meticulous sterile technique, careful tissue handling and antibiotic cover — and infection remains uncommon with either approach in experienced hands.
Temporary numbness of the lip and chin
The mental nerves supply sensation to the lower lip and chin, and the pocket is developed deliberately clear of them. Numbness or tingling while those nerves recover from swelling is common and settles over weeks; lasting sensory change is uncommon in experienced hands.
Asymmetry or displacement
Both come down to pocket work. A snug pocket made precisely on the bone holds the implant symmetrically, and once healed and integrated, displacement is rare. Avoiding impacts to the chin in the early weeks is the patient's half of that job.
Oversizing — the risk nobody frames as one
Ask surgeons who revise chin implants what they remove most and the answer is consistent: implants that were too large for the face. Slightly-too-small is a footnote most patients never act on; too big is a revision. Where measurement leaves a choice between two sizes, the smaller usually serves the face longer.
And the bone question. Long-term studies document that silicone chin implants can settle slightly into the bone surface over years — typically a few millimetres of smooth remodelling, visible on X-ray, usually self-limiting and very rarely clinically significant. Appropriate sizing and placement low on the sturdy part of the bone reduce it. Read the detail in silicone safety and the bone question, or the short answers in the FAQ. Individual results vary, and every risk here is discussed with you individually before any decision.
