There are four things you can do about a missing tooth, and only one of them is doing nothing. This page sets all four against each other, then points you to the specific treatment that fits your situation.

A dental implant replaces the root as well as the crown. A titanium post integrates with the jaw, and a crown is fitted on top. It does not involve the teeth either side, it keeps the bone loaded, and it is the most expensive option upfront.
A bridge spans the gap by crowning the teeth either side. Faster, no surgery, and usually less expensive. The cost is that two teeth get permanently cut down, and if they were healthy, that is a real price rather than a footnote.
A denture, full or partial, rests on the gums. The most accessible option, and the right answer for a great many patients. It moves, and the bone underneath keeps receding.
Leaving it is a real choice people make, and it is not free. What it costs is set out below.
Our Learning Center compares implants, bridges and dentures in more detail than fits here.
Nothing hurts, so the consequences arrive quietly.
The bone goes first. Bone is maintained by the load a tooth root transmits when you chew. Remove the root and the ridge resorbs, most rapidly in the first year, and it does not come back on its own. This is the mechanism behind the collapsed lower face that people associate with age rather than with tooth loss, and it is why a denture that fit five years ago is loose now.
The neighbors move. The teeth either side of a space drift toward it and tilt as they go. The tooth in the opposing jaw, with nothing to meet, erupts further out of its socket. Neither can be reversed by later filling the gap; an implant stops further drift but does not pull anything back. Once teeth have tilted, straightening them out becomes an orthodontic problem on top of a restorative one.
The bite changes. Tilted teeth do not meet cleanly, and uneven contacts concentrate force where it was not designed to go. That shows up years later as cracked teeth, sore jaw joints and accelerated wear.
Every month the gap stays open, the eventual treatment gets more involved.
Bone that has already gone has to be rebuilt with grafting before an implant can be placed, which adds months and cost. Teeth that have tilted may need moving before anything can be fitted between them. None of this makes treatment impossible, and plenty of people have implants placed years after losing a tooth. It just gets longer and more expensive the further it is left, which is the opposite of how most people assume it works.
Implant dentistry is not one procedure. Find yourself below and start there.
Single tooth implants. One implant, one crown, and the neighboring teeth left alone. The most straightforward case we do, and the one where the choice against a bridge is clearest.
Front tooth implants. Same surgery, a much harder result, because the gum contour and the shade match have to hold up next to a natural tooth in daylight. The planning starts before the tooth comes out.
All-on-4. A bridge screwed onto four implants, with the back two angled to use bone that survives tooth loss, which removes the graft from most cases. It does not come out.
Implant-supported dentures. A denture that clips onto two to four implants and lifts out at night. Considerably less expensive, easier to clean, and on a lower jaw it solves the complaint most denture wearers actually have.
Full mouth dental implants compares every full-arch option against the others, including how many implants each needs and what the maintenance involves.
Full mouth reconstruction, where implants are one part of a sequenced plan that also involves gum treatment, crowns and a rebuilt bite. Planned by our board eligible prosthodontist.
Orthophos SL 3D cone beam imaging. A three-dimensional scan of your jaw, taken in seconds, showing bone density, nerve position and sinus anatomy that a flat x-ray cannot. It uses less radiation than conventional cone beam units, though more than a routine intraoral x-ray, which is why it is taken when a case needs it rather than routinely.
Galileos Galaxis planning software. The scan is loaded into planning software where the implant is positioned virtually, in three dimensions, against nerves, blood vessels and soft tissue. It also shows where the implant will emerge, so the crown can be designed in the CEREC system and brought back into the plan. Both the implant and the crown are viewed together before anything is placed.
CEREC digital scanning and milling. A digital impression instead of a tray of putty, then the crown milled and glazed here on our CEREC system and Programat furnace. See our knowledge and technology for the rest.

Every case is different enough that a figure quoted before anyone has looked at your jaw is a guess. What moves the number is how many implants, whether extractions are involved, whether grafting is needed first, and what goes on top.
What we will do is give you a written figure before you commit, with your insurance benefits applied, and a figure for each alternative you are weighing so you can compare like with like. Coverage for implants is inconsistent between plans and usually capped by an annual maximum, and where it helps we phase treatment across two benefit years. We offer CareCredit, and our payment options page covers the plans we work with and the financing available.
Let's talk about replacing that tooth.
A consultation includes a 3D scan and a clear explanation of every option open to you, implant, bridge or denture, with a written figure for each. There is no obligation, and no decision is made on the day.
