I've had teeth removed years ago. Is it still possible to get implants?

dental implant is possible at any age and any time after extraction. but long time after extraction without restoration results in bone loss . for implant only thing matters is bone quantity. so in such case additional bone augmentation surgery might required. 

No you are not doomed.  You may need some bone grafting for certain dental implant options.  For other options like All On 4 Dental implant  procedures or teeth ia a day type procedures bone grafting isnt normally required.  There are multiple options for you.  Seea board certified oral and maxillofacial surgeon for your best options.

The most important factor for having implants is available bone. Most people in a situation similar to yours are still candidates for implants. The question is how many implants and what you want your replacement teeth to be. That can range from another denture which is supported by implants or a fixed bridge supported by implants. The difference being the number of implants you have. My recommendation is to see an Oral Surgeon for an evaluation to determine the quantity and quality of your bone support. Chances are, you can have implants!
