Root Canal Therapy
A toothache that wakes you up at night, lingers after hot coffee, or throbs when you bite down is your body telling you something specific: the nerve inside that tooth is in trouble. When the soft tissue at the center of a tooth becomes inflamed or infected, the discomfort rarely resolves on its own — and waiting usually means more pain and fewer options. Root canal therapy is how we treat the problem at its source, clear the infection, and keep your natural tooth in place rather than removing it.
Relieve Pain and Save Your Tooth
People come to us for this treatment from several different directions. Some have a tooth that has been quietly discolored for years after an old injury — a sign the nerve died long ago. Others chipped a tooth and found the exposed area suddenly sensitive to air and cold. Some have a deep cavity on a tooth that has grown past the point a filling can handle. And some arrive in acute pain with swelling or a small bump on the gum above the tooth, which can indicate an abscess.
Comfortable, Modern Treatment
With today’s techniques and technology, root canal therapy is more comfortable than ever. Our team focuses on gentle care and efficiency, making your visit as smooth and stress-free as possible.
What to expect
1. Exam And Diagnosis: We examine the tooth and talk through what is causing the pain and whether anterior root canal therapy is the right fit.
2. Comfortable Treatment Visit: We clean out the infected tissue inside the front tooth, then seal it to protect it.
3. Restore And Follow Up: We restore the tooth with a filling or crown and check in to make sure it feels and looks right.

Why People Love Signature Smiles
Stone J.
Absolutely incredible people all around! The entire staff is very polite and efficient! I got 12 fillings done in quick order with little to no discomfort (I honestly could have slept through most of it lol).
My teeth look brand new, and I’d highly recommend this dentist!
Sherry A.
I had been going to another local dentist for over 20 years but switched to Signature Smiles about a year ago because of a change in my insurance. I am very happy that my dentist is now Dr. Moreno! She is extremely thorough and competent! I highly recommend her and her office staff!
Mayra R.
I am a new patient of Dr. Moreno! The office scheduled me very quickly, i called and they had me in the very next day! the whole staff is super nice. Dr. Moreno made sure to explain my treatment plan to where i could understand and made me feel like she genuinely cares about my oral health.

I’ve haven’t laughed this much since my former dentist of 30 years retired (Dr. K. Grindley). Change is hard for many but change has been great with the new practice Signature Smiles! I lived in GB for 35 years and do not mind the drive to their office from Norfolk. It’s worth the trip!
Dr. Moreno is an amazing dentist and her support staff is awesome!
Hailey M.
I am a new patient of Dr. Moreno! The office scheduled me very quickly for both of my 6 month cleanings this year and also fit me right in for a filling appointment in the same week. I was in and out in 15 minutes for a filling too! Signature Smiles is very efficient and made coming to the dentist not feel like such a chore.
Todd S.
This was my first visit since Dr. Moreno took over from Dr. Graham, and I couldn’t be happier! Dr. Moreno and her team were super friendly, professional, and made me feel right at home. The whole experience was smooth and comfortable — definitely glad to be staying with Signature Smiles!
