Root Canals in Pico Rivera

A toothache is a symptom, not a diagnosis — it is your tooth’s way of saying something is wrong, and the causes range from a small cavity or a bite that needs adjusting to an infected nerve that needs root canal treatment. Some tooth pain settles on its own; pain from an infection does not, even when it quiets down for a while. At PhD Dental in Pico Rivera, at 8604 E. Whittier Blvd, Pico Rivera, CA 90660, an exam and X-rays are how we find the cause: we explain what we found, what we recommend and why, and what it will cost, in writing, before any work begins. Our general dentists perform root canals routinely at our Pico Rivera office, and patients in pain are a priority — we do our best to see emergencies the same day, and walk-ins are welcome.

What causes a toothache?

Most tooth pain starts in one of three places. The first is the nerve inside the tooth (the pulp): when decay, a crack, or a large old filling reaches or irritates the nerve, the nerve becomes inflamed — and because it is sealed inside a hard tooth, the inflammation has nowhere to expand, which is what makes it throb. If that inflammation goes too far, the nerve dies and bacteria infect the space inside the tooth. The second source is around the root: an infection that escapes the root tip forms an abscess in the bone, which is why an infected tooth often hurts to bite on or touch. The third source is outside the tooth itself — the gums (a pocket of infection or food trapped under the gum), the jaw muscles from grinding, or the sinuses, whose roots sit close to the upper back teeth. Because these causes need different treatments, the exam — not the pain’s intensity — is what identifies yours.

What do the different kinds of tooth pain mean?

Patterns give the dentist clues. Pain that zings briefly with cold and stops the moment the cold is gone usually points to sensitivity or early nerve irritation. Pain that lingers after hot or cold, starts on its own, throbs, or wakes you at night more often means the nerve is inflamed beyond settling or infected. Pain when you bite or release your bite can point to a crack, a high filling or crown, or an infection at the root tip. Pain in several upper teeth at once can be dental — or can come from the sinuses or from grinding. None of these patterns is a diagnosis by itself; they are why the dentist tests the tooth and takes an X-ray before recommending treatment.

What is a root canal?

A root canal is the treatment that saves a tooth whose nerve is infected or inflamed beyond healing. The dentist numbs the tooth, removes the infected or inflamed nerve tissue from inside it, cleans and disinfects the inside of the root, and seals it. The tooth stays in place — what is removed is the diseased tissue inside it, not the tooth itself. Root canal treatment is recommended when an evaluation shows the nerve cannot recover; it is the alternative to removing the tooth, and it relieves the pain the infection was causing. Our general dentists perform root canals routinely. Because a treated tooth can become brittle over time, a crown is often recommended afterward — especially on back teeth — to protect it when you chew.

Does a root canal hurt?

With modern numbing, a root canal feels similar to getting a filling. The tooth is fully numbed before we start, and most patients are surprised how comfortable it is. Some soreness afterward is normal and usually managed with over-the-counter pain relief — and treating the infection relieves the pain the tooth was causing. If you are anxious about treatment, tell us when you book: nitrous oxide is offered at select offices on request, and a calming medication for before the visit is an option some patients use — if you take it, you must have someone drive you to the office and home. We do not offer sleep dentistry.

How do I know if I need a root canal?

You know by an exam, because the deciding organ — the nerve inside the tooth — cannot be seen or self-tested. The symptom patterns that most often lead there are: pain that lingers after hot or cold, spontaneous or throbbing pain, pain that wakes you at night, a tooth that has gone quiet after a toothache (a dead nerve), a pimple on the gum, or a dark shadow at the root tip on an X-ray. At the visit, the dentist runs cold and tapping tests on the tooth and its neighbors, checks for swelling or a fistula, and reads the X-ray — and when those findings show the nerve is irreversibly inflamed, dead, or infected, a root canal is the treatment that saves the tooth. It is recommended only on those findings, never on symptoms alone.

Root canal or extraction — how is that decided?

By the tooth, not by a rule. Keeping your natural tooth is usually the better outcome when the tooth can predictably be treated and restored: a root canal plus a crown keeps your own tooth in place. Removal becomes the recommendation when the tooth cannot be saved — for example, a crack that runs through the root, decay that has destroyed too much of the tooth to rebuild, or bone loss too advanced to support it. If a tooth is removed, replacement options include dental implants (placed by our periodontist, Dr. Ori Levy, who sees patients across our offices on scheduled days), bridges, and dentures. Either way, the findings, the options, and a clear cost breakdown in writing are explained before you decide — and a second opinion is always a reasonable step.

Does insurance cover root canals in Pico Rivera?

PhD Dental accepts Medi-Cal and Denti-Cal at all eight of our offices. For Medi-Cal patients, root canals on front and back teeth are a covered benefit when the tooth qualifies, and emergency dental care — severe pain, infections, swelling — is covered as well. Many Medi-Cal procedures require pre-authorization, which we handle in-house and submit electronically for you as soon as the diagnosis is made — a decision typically takes about two to four weeks, the plan makes the final decision, and we let you know as soon as it comes back. We also accept these PPO plans: Aetna PPO, MetLife PPO, Delta Dental PPO, Cigna PPO, Guardian PPO, UnitedHealthcare PPO, Anthem Blue Cross PPO, Blue Shield of California PPO, Humana PPO, Principal PPO, Ameritas PPO, United Concordia PPO, Sun Life PPO, Lincoln Financial PPO, Unum PPO, The Hartford PPO, Renaissance Dental PPO, Premier Access PPO, and Health Net PPO. PhD Dental is in network with Delta Dental at all eight offices. Please note we do not accept any HMO plans at this time. Whatever your coverage, we verify your benefits and explain what your plan covers before treatment begins. Without insurance, the cost of a root canal depends on which tooth needs it — a front tooth is simpler than a back molar with several roots — and on whether the tooth also needs a crown afterward; a new-patient exam with a full set of X-rays costs $69 as a package, and we offer in-house payment plans and financing options so treatment costs can be spread over time.

We accept Medi-Cal. We accept Denti-Cal.

What happens if an infected tooth is not treated?

An infected tooth does not heal on its own. The infection at the root tip slowly destroys the bone around it, and it can flare at any time into a painful abscess with swelling. Pain that stops on its own usually means the nerve has died — the infection is still there and still spreading. Over time, an infection that could have been treated with a root canal can cost the tooth entirely. Facial swelling that is spreading, or swelling with a fever, needs urgent, same-day attention. Treating the tooth earlier is simpler, less costly, and keeps more of your natural tooth.

Common questions about root canals and toothaches in Pico Rivera

Do I still need a root canal if my toothache goes away?

Often, yes — pain that stops is not the same as a tooth that has healed. When a toothache fades on its own, the usual explanation is that the nerve inside the tooth has died, while the infection at the root is still active and spreading slowly through the bone. The tooth may look and feel fine for a while, then flare up much worse. Whether your tooth needs a root canal is decided by an exam and X-rays, not by whether it hurts today — but a toothache that “fixed itself” is exactly the kind that should be checked.

Why does my tooth hurt when I bite down?

Biting pain usually means something at the tooth is being stressed by pressure, and the common causes are: an infection or inflammation at the root tip (biting presses the tooth into its inflamed socket), a crack in the tooth that flexes under load, a filling or crown that is slightly too high and takes the force of every bite, or a deep gum pocket with its own infection. Which one you have is decided by how the tooth responds to testing — bite tests, tapping, and an X-ray of the root tip and bone. It is one of the more informative symptoms in dentistry, and it is worth having checked rather than chewing around it.

Can antibiotics eliminate a tooth infection?

No. Antibiotics can help control an infection that is spreading — reducing swelling and protecting the tissues around the tooth while treatment is arranged — but they cannot eliminate the infection itself, because the bacteria live inside a dead tooth where there is no blood flow to deliver the medicine. That is why a tooth infection treated with antibiotics alone reliably comes back: the source remains. The infection is eliminated only by treating the source — root canal treatment or removal of the tooth.

Why does my tooth still hurt after a root canal?

Some soreness after a root canal is normal — the tissues around the root tip were inflamed before treatment and have been worked around, so tenderness to biting for several days, sometimes up to a couple of weeks, is the common pattern, and it should be trending better, managed with over-the-counter pain relief. The patterns to call about: pain that is getting worse after the first few days instead of better, swelling, a bad taste, or sharp biting pain that feels like the tooth hits first — that last one is often simply the new filling or crown sitting slightly high, which a quick bite adjustment fixes.

Can a root canal fail years later?

Yes, it can — a root canal that was comfortable for years can become a problem again. The usual reasons: new decay or a leaking crown lets bacteria back into the sealed root; a canal that was not fully cleaned the first time slowly re-infects; or the tooth cracks under load. The signs are often quiet — a shadow returning at the root tip on a routine X-ray, a gum pimple — or the tooth may become tender to bite on. If that happens, the next step at our Pico Rivera office is a root canal retreatment evaluation: we re-examine the tooth with X-rays, explain why it failed, and lay out the options the evaluation supports, with a written plan and cost breakdown before any decision. The same evaluation-only approach applies if an instrument has separated inside a root — we evaluate the tooth’s infection status with X-rays and explain the monitoring or replacement planning the findings support.

Can a cracked root be repaired?

In most cases, no — and this is one of the few firm answers in dentistry. A crack that runs through the root itself splits the root’s seal, lets bacteria colonize the crack’s full length, and cannot be glued, filled, or healed shut; teeth with a true root fracture generally have to be removed. What can often be treated is a crack confined to the crown of the tooth — those are stabilized with a crown, with root canal treatment if the nerve is involved. Because the two look similar from the outside, the exam — bite tests, probing, and X-rays — is what separates them.

How long can a root canal-treated tooth last?

A well-treated, well-restored root canal tooth can serve for many years — very often for the rest of your life. The treatment itself is only half of that outcome; the other half is the restoration on top and the care afterward. Back teeth in particular usually need a crown: a crown typically lasts 10 to 15 years and many last longer with good home care and regular checkups, and it protects the treated tooth from cracking under chewing force. Regular checkups with periodic X-rays are part of the deal, because a treated tooth has no nerve to warn you if something new goes wrong.
