All-on-4 sounds almost too good to be true, a full set of teeth on four implants. So what's the catch? Dr. Spiros Karas, a general dentist in Manalapan, New Jersey, gives the honest version: what All-on-4 really is, the parts the ads leave out, and who it's genuinely right for.

What is All-on-4 and how does it work?

All-on-4 is a way to replace a full arch of teeth, the whole top or the whole bottom, using four implants as the anchors. Instead of a denture that sits on your gums and moves around, you get a fixed set of teeth that stays put. You brush them, you bite into your food, and they do not come out at night. For someone who has been struggling with dentures, that alone can be life-changing.

Is the set of teeth you get on day one permanent?

That set of teeth you walk out with on day one is usually a temporary set. It is real, it works, and you will not be without teeth. But your final set comes a bit later, after everything heals and settles. That is normal, and it is actually a good thing, but you should know it going in.

Is All-on-4 still a real surgery?

Yes, this is still a real procedure. It is very manageable, and most patients are amazed at how smooth it is, but it is surgery and it deserves respect. Healing takes time under the surface, even when the teeth look finished on top.

Do All-on-4 teeth need special care?

These teeth need care, just like natural teeth. You have to keep them clean, and you have to come in for checkups so we can make sure everything underneath stays healthy. All-on-4 is not a set-it-and-forget-it, it is a partnership that keeps working when you take care of your end.

Who is All-on-4 actually right for?

All-on-4 can be a wonderful choice for someone who has lost most or all of their teeth on an arch, who is tired of a denture that moves, and who wants something fixed and stable. Not everyone is a candidate on day one, and that is okay, sometimes we do a little groundwork first. The only way to know is a proper look and a scan.

Is All-on-4 too good to be true?

All-on-4 really can give someone their life back, I have seen it. But it is not magic, and it is not a shortcut. It is a real treatment that works beautifully when it is planned carefully and cared for afterward. If someone is promising you the world with no honest conversation about the trade-offs, slow down.
