Revascularization of the Open Apex: What to Expect

Revascularization of the Open Apex: What to Expect

Revascularization is a fairly new endodontic procedure that can restore the blood vessels in and around any of your teeth that need repair. This, in turn, can encourage healthy tissue growth and protect your teeth from further damage or infection.

Robert Scott Nance, DDS, MS, PA, and his expert team offer revascularization to protect and restore your teeth and their roots, and we want you to know what to expect from this endodontic treatment.

Understanding open apex and necrosis

Revascularization is typically needed for teeth that have underdeveloped roots. Having underdeveloped teeth roots can occur because of teeth with an open apex or from pulp necrosis. If you need revascularization because of an open apex or necrosis, it’s good to take a closer look at what they are and how they’re caused.

Open apex

Your tooth's apex, or tip, is rooted in your jaw. When you first get your permanent teeth, it takes about 3 years for the apex to fully close. However, if it’s never able to close properly, that tooth is at high risk for bacteria being able to enter and infect it. 

You can also have an open apex from the tip of your tooth eroding away through a process called resorption.


Necrosis means “tissue death” and can happen anywhere in your body. It can happen to the pulp in your teeth when cavities and infections are left untreated. This can lead to delayed tooth root development and eventual tooth loss.

An open apex and pulp necrosis can cause extreme damage to your teeth, but revascularization can offer a way to regenerate healthy tissue and reverse the effects of these hazardous dental conditions.

What to expect from the revascularization process

Revascularization will require at least two appointments to complete. 

During the first session, Dr. Nance will remove debris, clean the tooth, and inject antibiotics to get rid of any lingering infection. 

He will treat your tooth root at the second appointment to increase blood flow and blood vessel development. This will encourage the apex of your tooth to close to prevent decay and tooth loss down the road. 

If you need revascularization or any other expert endodontic procedure, call one of Dr. Nance’s offices in Statesville and Hickory, North Carolina, to set up an appointment today.
