When a number of teeth are missing, there are various options available. You may choose to have a denture. But over time, your gums will recede and the denture may not fit as well.
You could choose to have Implants to secure the denture. One way is a small number of Implants with a bar and magnets to hold the denture. Another way is a small number of Implants to which the denture is secured or a greater number of Implants onto which a set of teeth are permanently fitted.
