Root Canal Treatment in Hillsboro — Save Your Tooth and Stop the Pain

After about 800 root canals at this office, the most common reaction afterward is some version of: “That was way easier than I expected.” The procedure feels essentially like a long filling appointment under local anesthesia. The throbbing, sleep-killing toothache that brought most patients in is what hurts. The treatment that fixes it does not.

Dr. Ostovar uses NSK ProTaper Gold and Reciproc Blue rotary files (nickel-titanium, more flexible than older stainless instruments, fewer ledges and perforations), a Carestream CBCT for canals that look funky on 2D X-rays, and digital apex locators to measure each canal to the exact root tip. We also hold a 2pm slot daily for emergency appointments — most acute pulpal pain (the throb that won’t quit) gets seen same day.

When Do You Need a Root Canal?

The pulp is the soft tissue inside your tooth containing nerves, blood vessels, and connective tissue. It extends from the crown of the tooth down through narrow channels (canals) in each root. When this pulp becomes infected or irreversibly inflamed, a root canal is the only treatment that can save the tooth — the American Association of Endodontists confirms it as the standard of care for these cases, with success rates above 95% when performed by experienced clinicians.

In my experience treating root canals for Hillsboro patients over the past 15+ years, the biggest barrier is not the procedure itself — it is the fear of the procedure. Modern endodontic techniques, combined with precise local anesthesia and rotary instrumentation, mean most patients feel less discomfort than a standard filling. As a Fellow of the Academy of General Dentistry (FAGD), I stay current with the latest endodontic research and techniques, so I can offer the most comfortable, predictable root canal treatment available.

Common causes of pulp damage:

• Deep decay — a cavity that progresses through the enamel and dentin into the pulp chamber
• Cracked or fractured tooth — a crack that extends deep enough to expose the pulp to bacteria
• Repeated dental procedures — a tooth that has had multiple fillings or crowns over the years, each progressively closer to the nerve
• Trauma — a blow to a tooth (from sports, falls, or accidents) can damage the pulp even if the tooth looks intact externally
• Large failing restoration — an old filling or crown that has leaked, allowing bacteria to reach the pulp underneath

Signs You May Need a Root Canal

• Severe, throbbing toothache that wakes you up at night or persists for hours
• Prolonged sensitivity to hot or cold — pain that lingers for 30 seconds or more after the stimulus is removed (normal sensitivity resolves in a few seconds)
• Pain when chewing or touching the tooth — indicates the tissue around the root tip is inflamed
• Swelling in the gum near the affected tooth — may indicate an abscess (infection at the root tip)
• A pimple-like bump (fistula) on the gum — a drainage point for a chronic abscess
• Darkening of the tooth — a tooth that turns gray or dark yellow may have a dying or dead nerve
• Spontaneous pain — pain that comes and goes without any trigger

Not all of these symptoms always mean a root canal is needed, and not every tooth that needs a root canal produces obvious symptoms. That is why dental X-rays and clinical testing (cold test, percussion test, electric pulp test) are essential for accurate diagnosis.

The Root Canal Procedure at East Wind Dental Care

Before the Procedure

Dr. Ostovar takes digital X-rays of the affected tooth to evaluate the number and shape of the root canals, the extent of infection, and the condition of the surrounding bone. He explains the diagnosis, treatment plan, and alternatives so you can make an informed decision.

During the Procedure (45–90 Minutes)

1. Anesthesia — Local anesthesia is administered to completely numb the tooth and surrounding area. Sedation (nitrous oxide or oral sedation) is available for patients who are anxious. You should feel no pain during the procedure.
2. Isolation — A small rubber dam (dental dam) is placed over the tooth to keep it dry and prevent debris from entering your mouth. This is a standard infection-control practice.
3. Access opening — Dr. Ostovar creates a small opening through the top of the tooth (for a back tooth) or the back of the tooth (for a front tooth) to access the pulp chamber.
4. Pulp removal — Using rotary endodontic instruments (nickel-titanium files), the infected or dead pulp tissue is carefully removed from the pulp chamber and each root canal. The canals are shaped to allow thorough cleaning and filling.
5. Irrigation and disinfection — The canals are flushed with sodium hypochlorite (a disinfecting solution) and other irrigants to kill bacteria and dissolve remaining tissue debris.
6. Length measurement — A digital apex locator electronically measures the precise length of each canal to ensure the files reach the tip of the root but do not extend beyond it. This is confirmed with X-rays.
7. Canal filling — The cleaned, shaped canals are filled with gutta-percha (a biocompatible rubber-like material) and sealed with adhesive cement. This fills the space where the nerve and blood vessels once were, preventing bacteria from re-entering.
8. Temporary or permanent restoration — A temporary filling is placed in the access opening. In many cases, Dr. Ostovar can immediately prepare the tooth for a permanent crown at the same appointment.

After the Procedure

• Numbness wears off in two to four hours
• Mild soreness when biting is normal for three to seven days and responds well to over-the-counter pain medication (ibuprofen or acetaminophen)
• Avoid chewing on the treated tooth until the permanent crown is placed
• Return for a crown within two to four weeks (or same day with CEREC)

Why a Crown Is Needed After Root Canal

A tooth that has had a root canal is structurally weakened — the access opening, the removal of internal tissue, and the pre-existing decay or fracture all reduce the remaining tooth structure. Without a crown, the tooth is at high risk for fracture during normal chewing.

Dr. Ostovar strongly recommends a crown on every back tooth (molar or premolar) that receives root canal therapy. Front teeth sometimes survive with just a bonded filling if enough tooth structure remains, but a crown is still the safer long-term option.

With our CEREC same-day crown system, the root canal and permanent crown can often be completed in a single extended appointment — saving you a return visit.

Root Canal vs. Extraction — Which Is Better?

| Factor | Root Canal + Crown | Extraction + Implant |
|—|—|—|
| Preserves natural tooth | Yes | No — tooth is removed |
| Treatment time | 1–2 appointments | 4–8 months (extraction + healing + implant + crown) |
| Cost | $1,500 – $2,500 (root canal + crown) | $3,500 – $5,500 (extraction + implant + crown) |
| Success rate | 90–95% over 10 years | 95–98% over 10 years |
| Bone preservation | Natural root keeps bone | Implant preserves bone after extraction |
| When it’s the right call | Tooth has enough structure to support a crown | Tooth is cracked below the bone, has severe root fracture, or cannot be restored |

The general rule: If a tooth can be saved with a root canal, saving it is almost always the better option. Extraction should be a last resort, not a first choice. Dr. Ostovar will give you an honest assessment of whether your tooth is worth saving.
