“How long after extraction can I get a bridge?”

Usually a minimum of 6-8 weeks but normally I will go ahead and place a temporary bridge until the area properly heals then fabricate the bridge that way you aren’t going around without a tooth.

It depends on several things. First of all, where is the tooth? If it’s in the front of your mouth you’re going to need something temporary to be able to walk around and smile and not be self-conscious about the missing tooth. Second of all, it depends on whether you want to have as much healing of the bone occur before you have a final bridge placed (assuming you’re talking about a permanent fixed bridge not a removable) and that can take 6 months to a year for bone remodeling to occur. Even a removable partial denture can need to be re-lined if enough time doesn’t elapsed before your impressions are taken for that appliance. If your dentist recommends finishing it before, then you will have space develop in the area underneath the replacement tooth and it may or may not be a problem, but just so you know. Many patients elect a two phase treatment so that they can have a temporary prosthesis for a year and then proceed to the permanent bridge after all the bone healing as occurred.
Hope this helps.

I recommend waiting 6 weeks. During that healing period, the bone where the tooth used to be changes and remodels. To have a well-fitting bridge that won't have a large gap and food trap under the fake tooth, it is best to wait the full 6 weeks prior to the impression.

There are 2 trains of through registering this:

1) you could immediately temporize so the bottom side of the floating tooth (Pontic) can train the tissue so it looks like it's growing out of the tissue or
2) you can wait and let the tissues heal and do the bridge after 3-4 weeks of healing. For me, I’d usually do pathway 1 for missing anterior teeth and sometime first bicuspids and pathway 2 for posterior teeth.

Always consider an implant as an option, as it is the best tooth for tooth replacement because it retains the natural tooth structure of healthy neighboring teeth and can have a much longer long-term prognosis (better longevity).
