Endodontics, explained

Endodontics is a dental specialty focused on the inside of the tooth. Each tooth contains soft tissue called pulp (nerves and blood vessels). While pulp is essential during development, many mature teeth can function after pulp is removed when necessary—this is the basis of root canal therapy.¹²

At Litchfield Dental Care, we check for signs of pulp damage during exams and encourage you to reach out promptly if you experience tooth pain or sensitivity. We use imaging to evaluate the tooth and recommend the most conservative path forward.

What is endodontics?

Endodontics refers to the diagnosis and treatment of problems involving the tooth pulp and surrounding tissues. Pulp can become inflamed or infected due to deep decay, cracks, trauma, or repeated dental procedures. When this happens, root canal therapy is a common treatment to remove the infected pulp, disinfect the canal system, and seal the tooth.¹²

Comfort note: With modern anesthesia and techniques, root canal treatment is typically comparable to getting a filling—and it’s performed to relieve pain, not cause it.¹

When do I need endodontics?

Severe tooth pain or lingering sensitivity is a sign something isn’t right. Contact us promptly if you have symptoms that could indicate pulp inflammation or infection. Untreated infection can lead to an abscess and more complex care.²³

Pimple-like bump on the gums
Swelling or gum inflammation
Sensitivity to hot or cold

Darkening tooth or gum tissue
Deep chips or cracks
Pain when chewing or biting

How does root canal therapy work?

Root canal therapy treats an infected or inflamed pulp by removing the tissue, cleaning and shaping the canal system, and sealing it. The tooth is then restored—often with a filling or crown—to protect strength and function.¹²

Numb & access — local anesthesia, then a small opening to reach the pulp.

Remove & disinfect — infected tissue is removed; canals are cleaned.

Shape & seal — canals are prepared and sealed to protect the tooth.

Restore — filling or crown to reinforce the tooth for long-term use.²

Goal: preserve your natural tooth whenever possible and return you to comfort with a durable restoration.¹²

Endodontics FAQs

Do root canals hurt?

Root canal therapy is performed with local anesthesia. It’s intended to relieve pain from infection or inflammation, and many patients report it feels similar to getting a filling.¹

What symptoms suggest I may need a root canal?

Persistent tooth pain, lingering sensitivity to heat/cold, swelling, or a gum “pimple” can signal pulp infection or inflammation. Evaluation and imaging confirm the cause.²³

Why save the natural tooth?

Saving a natural tooth helps maintain normal chewing function and bite balance. Root canal therapy is commonly used to preserve teeth that would otherwise need extraction.¹²

Will I need a crown after a root canal?

Often, yes—especially for back teeth—because a crown can protect the tooth after treatment. Your dentist will recommend the best restoration for your tooth and bite.²

How soon should I be seen if I have swelling or severe pain?

As soon as possible. Severe pain or swelling can indicate infection that may worsen without treatment. Call right away for guidance and scheduling.
