“What is the procedure for restoring a missing tooth?”

Replacing a tooth requires a full evaluation of the mouth in general. Typically the mechanical answer to that question is a removable partial denture, a fixed bridge or an implant. Which is applicable depends on the condition of the immediately surrounding teeth and all the teeth in general since one tooth is but one part of the whole.

There are several options, but if there are adjacent teeth, then it can be restored with an implant, permanent bridge, or a removable appliance.

Even if the visible part of your tooth is broken a dentist can determine if the remaining root is strong enough to hold a new tooth (crown). The first step is an xray and if the root is strong a reinforcing post can be used to replace your broken tooth

Each case is different. In general, you can replace a tooth with an implant and after the implant is solid, you use an implant crown. (The implant is like a dentist made root.) You can opt for a fixed bridge when you have two strong teeth in either side of the missing tooth.

Several ways to replace a missing tooth
1) a permanent3 unit bridge
2) a removable flipper
3) a Maryland bridge
4) a Implant/abutment/crown

I am sorry to hear about your tooth. First, the surgeon must preserve the bone, then to restore the missing tooth, you have several options:

1- tooth implant (if you have enough bone): https://best.celebritydentist.com/dental-implants/
2- a permanent fixed bridge, if you have teeth on both sides of missing tooth with enough bone: https://best.celebritydentist.com/dental-bridges/
3- partial removable denture

Which way is the best to restore a missing tooth? It all depends on your X-rays, bone level, and the adjacent teeth next to missing tooth, see an expert dentist right away for a consultation, duration of treatment, and the cost.
Best of luck!
