There are rare allergic reactions to titanium, which can possibly lead to implant failures. Symptoms associated with a titanium allergy or titanium sensitivity are:
- Erythema, which causes redness in the tissues around the implant
- Swelling or pain at the implant site
- Bone loss
There are also many other factors that can contribute to dental implant failure, including smoking, gum disease, medical conditions that inhibit healing, and poor oral hygiene.
