Same day emergency root canal treatment

Signs you need an emergency root canal

Not every toothache is an emergency, but the ones caused by an infected nerve get worse, not better, and they do it fast. Call us the same day if you have:

• Throbbing or pulsing pain in one tooth that comes on without anything touching it
• Pain that wakes you up at night or gets worse when you lie down
• Lingering sensitivity to hot or cold that keeps aching for more than a few seconds after the trigger is gone
• Sharp pain when biting or chewing on a specific tooth
• Swelling in the gum around a tooth, in the jaw, or in the cheek
• A pimple or bump on the gum near the tooth, sometimes draining a bad tasting fluid
• A tooth that has turned gray or dark compared with its neighbors
• Pain relievers that no longer work, or that only work for an hour or two

If swelling is spreading toward your eye or down your neck, you have a fever, or you are having trouble swallowing or breathing, go to a hospital emergency room first. Those are signs the infection is moving beyond the tooth. Otherwise, call us at (916) 538-6900.

What is happening inside the tooth

Inside every tooth is a small chamber of nerve tissue and blood vessels called the pulp. When deep decay, a crack, a large old filling, or a blow to the tooth lets bacteria reach the pulp, it becomes inflamed. In the early stage, called reversible pulpitis, the tooth is sensitive but the nerve can still recover if the cause is removed. Once the inflammation crosses a line, the nerve cannot heal. This is irreversible pulpitis, and it is the source of the spontaneous, throbbing pain that brings most patients in.

Left alone, the nerve dies and bacteria spread out of the root tip into the bone, forming an abscess. Pressure builds inside a space that has nowhere to expand, which is why the pain is so intense and why it pulses with your heartbeat. Eventually the abscess finds a path through the bone and gum, forming the pimple-like bump many patients notice. The bump draining can make the pain drop off suddenly. The infection is still there.

Tooth infections are not something to wait out. Before antibiotics, dental abscesses were a common cause of death, and even today they can spread into the jaw, the sinuses, the neck, and the bloodstream. The earlier the tooth is treated, the simpler the treatment and the better the odds of saving it.

What we do the same day

1. Get you in. We reserve time in every day's schedule for emergencies. Calling first thing in the morning almost always means being seen that day.
2. Find the source. A focused exam, X-rays, and pulp testing confirm which tooth is responsible. Referred pain is common, and treating the wrong tooth helps no one. 3D imaging is used when the picture is unclear.
3. Get you numb. An inflamed tooth is harder to numb, so we go slowly, use supplemental techniques when needed, and do not start until you are comfortable.
4. Relieve the pressure. We open the tooth and remove the infected nerve tissue. For an abscess, this alone releases the pressure that is causing the pain. If there is a swelling that can be drained, we drain it.
5. Complete or stabilize. When the tooth and the schedule allow, we finish the root canal in the same visit: clean, shape, disinfect, and seal the canals. For severe infections, we place medication inside the tooth, seal it temporarily, and complete the treatment at a follow-up visit once the infection has calmed. Both approaches get you out of pain today.
6. Plan the restoration. Back teeth need a crown after root canal treatment to prevent fracture. We schedule it before you leave.

When the tooth cannot be saved, we say so honestly and discuss extraction and replacement instead. For teeth with complex anatomy, retreatments, or infections that have resisted previous treatment, we add laser-assisted disinfection to reach bacteria conventional cleaning misses. Emergency endodontic care at our office is led by Dr. Marjoorie Castro, whose advanced endodontic training means even difficult cases stay in house.

Why antibiotics alone are not enough

Patients are often surprised when a course of antibiotics from an urgent care clinic helps for a week and then the pain returns worse than before. The reason is simple. Antibiotics travel through the bloodstream, and an infected pulp has lost its blood supply. The medication cannot reach the bacteria inside the tooth. It can reduce the swelling in the surrounding tissue, which is why it feels better temporarily, and why we sometimes prescribe it alongside treatment when there is facial swelling. But once the course ends, the bacteria inside the tooth simply repopulate the area.

The only durable fix is removing the source: either the infected tissue inside the tooth through a root canal, or the tooth itself through extraction. Repeated rounds of antibiotics without definitive treatment also contribute to antibiotic resistance, which is why current guidelines discourage prescribing them as a substitute for dental treatment.

What to do until you are seen

• Call us first so we can hold a slot and be ready for you.
• Alternate ibuprofen and acetaminophen as directed on the packages, unless you have a medical reason not to take one of them. Together they control dental pain better than either alone.
• Do not put aspirin on the gum. It burns the tissue and does not help the tooth.
• Cold compress on the cheek, 20 minutes on and 20 off, for swelling. Avoid heat, which draws the infection outward.
• Keep your head elevated when lying down. Pressure increases when you are flat, which is why the pain is worse at night.
• Avoid very hot, cold, or sweet foods and chew on the other side.
• Bring a list of your medications and any allergies to your appointment.

After hours and weekends

Our office is open Monday through Friday. Evenings, weekends, and holidays are covered by our after hours line at (916) 581-3363, which will help you decide whether you can be managed until the next business morning or should head to an emergency room. Our office is at 1105 E Street, Sacramento, CA 95814 in midtown, with street parking on E Street and 11th Street.

Cost, insurance, and the $59 offer

The cost of an emergency root canal depends on the tooth. Front teeth and most premolars have one or two canals; molars have three or four and take longer. Most dental insurance plans cover emergency exams, X-rays, and root canal treatment, typically at 50% to 80% after the deductible. We file claims directly and tell you your estimated portion before we begin.

If you are a new patient without dental insurance, our $59 emergency offer covers the focused exam and the X-rays needed to diagnose the tooth, and takes 20% off our standard fee for the treatment that resolves the emergency the same visit, including a root canal. Payment is due at the time of service, and the discounted balance can be financed through Cherry or CareCredit. A root canal and crown is almost always less expensive over time than extraction and an implant, and you keep your own tooth.
