What’s an All on 4 Procedure for Your Teeth?

Traditionally, patients missing all teeth in either jaw had few options other than dentures which rested against the gum line. All on 4 implants offer a far more secure solution.

This revolutionary dental implant procedure1 utilizes four titanium screws to support a full arch of replacement teeth without the need for bone grafts and sinus lifts typically associated with other implant solutions. All on 4 implant dentistry Vaughan is a great solution for those looking to replace their teeth and secure a durable, comfortable, and aesthetically pleasing smile for years to come!

How It Works

All on 4 or ‘Teeth in a Day’ is an innovative dental treatment developed to restore multiple missing teeth quickly, improving both smile and function. Our specialist lab uses just four implants to support an entire bridge of replacement teeth made for you by us – something other conventional dental procedures cannot match.

Full mouth rehabilitation using All on 4 implants can typically be accomplished in one visit, taking only around two hours. This process includes extracting existing teeth, reshaping jaw bone structure, and then placing 4-6 implants that will support permanent replacement teeth2.

A dentist will conduct a comprehensive exam, taking x-rays and digital 3D scans of their patient to gain an in-depth knowledge of their oral health history and any issues that will require addressing prior to starting surgery. He/she may also take note of any medications the patient is currently taking as some can interact with local anesthetics3 or painkillers during procedures.


The all-on-4 Procedure offers patients an effective solution for replacing both sets of upper and lower teeth in one surgical session with permanent dental bridges, giving them more freedom from worrying about losing any additional healthy teeth or adhesives or denture glue.

If you are considering an all-on-4 implant procedure, the first step should be speaking to your dentist to discuss all the details of your case and decide whether this solution is the best choice based on factors like the state of your healthy teeth, bone density4, and other variables.

Make sure that someone is available to drive you to and from your appointment as the effects of anesthesia may linger post-procedure. Also stocking your fridge with soft foods prior to the All on 4 procedure can help as you won’t be able to chew for several weeks post-surgery and it may take up to three months for complete osseointegration5 to occur.


The surgery phase of All on 4 involves placing four dental implants in your jaw. Your dentist will conduct an X-ray examination to evaluate your bone density for implant placement and will inquire further into your medical history and lifestyle factors that could potentially impede your suitability for this treatment.

As part of your procedure, you’ll be administered general anesthesia or sedation so you won’t experience any pain. Your dentist will make sure there is nothing in your stomach before beginning.

As soon as your implant sites heal, permanent dentures can be fitted. Since they will be securely attached to implants, these dentures should remain securely in your jaw without shifting or becoming loose – providing much greater comfort than dentures that rub against gums and cause pain and other issues. It’s best to consume soft foods during treatment while refraining from smoking or alcohol consumption which could slow the healing process or worsen complications with implants.

Post-Operative Care

All on 4 (also known as Teeth in a Day) is an effective treatment method that uses four implants to support an arch of replacement teeth that look and feel just like natural ones.

All-on-4 provides a more comfortable alternative to dentures; using this technique, dentists can replace an entire upper or lower arch of missing or damaged teeth in just one surgery session.

During their recovery period, patients should avoid eating hard or chewy foods as this can damage implant sites and take pain relievers as needed. Furthermore, they should rinse their mouth with salt water two to three times each day as part of an aftercare program. Moreover, they should refrain from smoking or alcohol as these can hinder healing processes.

With only four screw mounts required to secure an entire set of teeth, this procedure is less invasive than other forms of dental implants. Still, patients should carefully consider if this treatment option is right for them before making their decision.
