What is smile in a day treatment?

Smile in a day treatment is a long-lasting solution for replacing loose, rotten, missing or failing teeth with a full set of dental implants in one day. The technique is usually used for people with little or no teeth and it's an alternative to the traditional placement of multiple dental implants, or a full set of dentures.

A set of four to six dental implants replace a whole arch of missing teeth and are usually fitted all in the same day.

You might also hear smile in a day treatment referred to as teeth in a day, full mouth dental implants or All-On-4 dental implants.

How does smile in a day work?

The smile in a day procedure is usually carried out under local anaesthetic or using dental sedation. The selected teeth are replaced with four to six implants, which are surgically placed into your jawbone. Then a custom-made, temporary bridge is fitted to the implants to support them. This bridge is usually replaced three to four months later with a long-term bridge.


In most cases, the implants and temporary bridge are fitted in one day – hence the name of the treatment. There are rare occasions when treatment can’t be completed in a day, as sometimes bone loss in the jaw means implants can’t be supported straight away.

In this case a temporary, removable denture may be placed, which isn’t attached to the implants. The bridge is then placed a few months later once the implants are fixed into the bone.

The diagram shows how the implants are fitted onto the jawbone.
