All-On-Four (Teeth-In-A-Day)


All-On-Four (Teeth-In-A-Day)

Remember all those old ads for denture adhesives. They all promised theirs was finally the product that would hold your dentures in place. The commercials ended with either a guy eating an apple or a woman working on an ear of corn. Smiles everywhere. Of course, we were all skeptical. In the back of your mind, you thought to yourself; I sure hope they come up with a better solution by the time I need new teeth. Well, they did.

All-On-Four, also called “Teeth-in-a-Day,” is that better solution. The first thing to know is you’ll come in once for a consultation and measurements. We’ll explain the advantages and answer all of your questions. Later, you’ll come back with your current teeth, and you’ll leave that same day with a perfect, all-new smile. It really is “teeth-in-a-day.” It’s a permanent solution that, unlike dentures, really will have you eating that apple.

What is it?

All-on-Four starts with four dental implants. These are small titanium screws that are inserted into your jaws. That might sound severe, but you’ll be sleeping through all of this. Then, a permanent denture is attached to those screws. You’ll walk out with a seamless row of teeth, across your entire mouth.

There are many advantages to this approach, however, it’s not right for everyone. 3D x-rays and a thorough examination will be needed for our doctors to know if you are a candidate. If you are, you will:

Replace your entire set of missing teeth in just one day, with one surgery.
They permanently attach so you won’t ever have to worry about them loosening.
All-on-Four will save you money over replacing each tooth individually.
Typically, no bone grafting is necessary.
Recovery time is faster than other treatment options.

Your Dental Specialties dentist will go over the potential drawbacks with you. This isn’t a one-size fit all kind of deal, so we consider this one-on-one consultation essential.

For these reasons, you want expert dentists who have done thousands of these procedures. It’s smart that you’re on this page, learning about Dental Specialties.
