Treatments
What we do, in plain words
Endodontics treats the inside of the tooth: the pulp, the canals and the tissue around the root tip. The goal is simple — relieve pain and keep your natural tooth.
Microscopic examination
We examine the tooth under high magnification and light to find cracks, hidden canals and the real source of pain. Many “mystery” toothaches get a clear answer here.
Root canal treatment
We remove inflamed or infected pulp, clean and shape the canals, and seal them. With local anesthesia it feels much like getting a filling.
Retreatment
When a previous root canal didn’t heal, we remove the old filling material, find what was missed and seal the tooth again.
Surgical endodontics
If infection persists at the root tip, we reach it through the gum, remove the infected tissue and seal the end of the root (apicoectomy).
3D imaging (CBCT)
A cone beam scan shows root shape, bone and lesions that regular X-rays can miss, so the plan is based on what is really there.
Referred by your dentist?
Many patients come from their general dentist. We coordinate with their office so your crown or final restoration follows without delays.

Why the microscope
You can’t treat what you can’t see.
Root canals can be narrower than a hair. The surgical microscope adds magnification and light directly into the tooth.
See more
Extra canals, fractures and calcifications become visible.
Remove less
Smaller access openings keep more of your natural tooth.
Fewer surprises
Each step is precise and can be documented on video and photo.
A teaching practice
Dr. Hernández founded the first endodontic microscope teaching center in Los Algodones.

How we work
- Save the natural tooth when it’s the right call.
- Explain the diagnosis and options before treating.
- Precision first. We don’t rush a root canal.

FAQ
Common questions
Book appointmentDoes a root canal hurt?
With modern local anesthesia, most patients say it feels like getting a filling. Some tenderness for a few days afterward is normal and is usually managed with over-the-counter pain relievers.
How many visits will I need?
Many cases are finished in one visit. Teeth with active infection, retreatments or complex anatomy may need two. We tell you at the diagnosis.
Why see an endodontist instead of my general dentist?
Endodontists complete additional years of specialty training and treat root canals every day. Complex anatomy, retreatment and root-end surgery are routine work for us.
What happens after the root canal?
Most back teeth need a crown to protect them. Your general dentist usually places it; we send them the information they need.
Do you accept insurance?
We don’t bill insurance directly. We provide the documentation you need to file a claim with your insurer for reimbursement.
How can I pay?
Cash or personal check. We do not accept credit or debit cards. Consultations have a fee.
What do I need to cross the border?
To re-enter the U.S. you need a valid passport, passport card or another accepted travel document. Check current requirements with U.S. Customs and Border Protection before your trip.
What if I need to cancel?
Please let us know at least 2 business days in advance to cancel or reschedule.
Do you speak English?
Yes. Our team serves patients in English and Spanish, and our reception is fully bilingual.
