Discover the warning signs of root canal needs and understand what modern root canal procedures actually involve.

Summary:
Persistent tooth pain is one of the most common signs that you may need a root canal. This isn’t the occasional twinge you feel when biting something hard – it’s pain that bothers you consistently or comes and goes repeatedly.
You may feel the pain deep in the bone of your tooth, often radiating to other parts of your face. The discomfort can range from a dull, constant ache to sharp, intense pain that interferes with daily activities like eating or sleeping.
Many physical symptoms don’t start until the problem has become more advanced, which is why it’s important to see your dentist regularly and not ignore early warning signs.
A new sensitivity to hot or cold temperatures may be the only signal that a tooth needs a root canal. While occasional sensitivity isn’t unusual, persistent discomfort when consuming hot or cold foods and drinks is concerning.
It’s not uncommon for extreme temperatures to cause a little twinge occasionally, but what’s less common is when that “twinge feeling” is prolonged and consistent. Some people experience only minor discomfort, while others have severe pain when biting into hot pizza or drinking iced tea.
The key difference is duration and intensity. Normal tooth sensitivity typically subsides quickly after the temperature stimulus is removed. Root canal-related sensitivity lingers and often worsens over time.
When decay gets into the soft core of your tooth, the pulp can become inflamed, infected, or even necrotic (dead), requiring a root canal to clean out the decay. This infection creates the prolonged sensitivity because the nerve inside your tooth is responding to the bacterial invasion.
If you notice that your sensitivity to temperatures has increased significantly or persists long after eating or drinking, it’s time to schedule a dental examination.

A root canal procedure sounds scary, but with today’s technology, it’s typically not much different than having a deep filling, with little to no pain because we use local anesthesia to numb your tooth and gums.
A root canal is a procedure that removes infected pulp from inside your tooth, with careful cleaning and sealing of the canals to prevent further damage and save your tooth. The goal is always preservation – keeping your natural tooth rather than extracting it.
Root canal treatment involves carefully cleaning and disinfecting the inside of the tooth, then filling and sealing it to eliminate bacteria from the infected root canal and prevent reinfection.
Understanding exactly what happens can help ease your anxiety about the procedure. Before treatment, we examine your tooth with X-rays and other tests to confirm the infection.
If you need a root canal and have facial swelling or a fever, we may give you antibiotics beforehand to kill the infection, which may also help reduce your pain. This pre-treatment ensures you’re comfortable and the infection is manageable.
The root canal procedure itself is similar to getting a large filling, but it’ll take longer. Most root canals can be done in one to two appointments, with the first appointment being the procedure itself when the infected pulp is removed.
During the procedure, we create a small access hole in your tooth to reach the infected pulp. Your teeth have an enamel layer on the outside, a second layer of dentin, and a soft inside core that extends into the root in your jawbone – this core contains the dental pulp, which consists of nerves, blood vessels, and connective tissue.
The infected tissue is carefully removed, and the inside of your tooth is thoroughly cleaned and disinfected. Once clean, the space is filled with a biocompatible material and sealed. You’ll likely have two more appointments: one to prepare for your crown and one to place it.
Most people recover in less than a week, and you might have some lingering sensitivity, but you shouldn’t have pain that lasts longer than that. You may feel pressure during the procedure, and mild soreness afterward.
Good care helps with root canal recovery through simple steps like avoiding smoking, brushing after meals and flossing once daily, not chewing on the treated tooth until your permanent crown is placed, and eating soft foods for a few days.
Most root canals are successful and can last for many years — often a lifetime. Most endodontically treated teeth last as long as other natural teeth. This makes root canal treatment an excellent investment in your long-term oral health.
A root canal does not kill the tooth, and after completion, the tooth will function normally – root canals do remove the nerves inside the tooth, but these nerves serve very little function in a fully formed tooth.
If you have root canal pain, don’t wait – treatment can relieve pain, save your tooth and prevent the infection from spreading. The sooner you address the problem, the better your outcome will be.
According to studies, the overall success rate of endodontic treatment ranges between 86% to 98%, though a small percentage of patients may develop further problems months or years later. However, these cases can often be successfully retreated.
Root canal infections won’t heal on their own, so it’s important to see a dentist – if you need a root canal, we guide you through the process so you know what to expect. The key is finding a dentist you trust who has extensive experience with root canal procedures.
The sooner your tooth can be treated, the better the outcome will likely be. Don’t let fear or uncertainty keep you from getting the care you need. Modern root canal therapy is far more comfortable than many people expect.
