Cavities, those annoying little holes in our teeth, are a common dental problem that affects people of all ages. If left untreated, cavities can lead to severe tooth pain, infection, and even tooth loss. While most cavities can be treated with a simple dental filling, some cases require more extensive care, such as root canal treatment. In this article, we will explore when a root canal treatment is necessary and shed light on this often misunderstood dental procedure.
What Are Cavities
Cavities, also known as tooth decay, are caused by a combination of factors, including bacteria, poor oral hygiene, a high-sugar diet, and genetic predisposition. When plaque, a sticky film of bacteria, forms on the teeth and combines with sugars from food or drinks, it produces acids that attack the tooth enamel. Over time, this acid erosion creates small openings or cavities in the tooth structure.
To know about when root canal treatment is required, we spoke to Dr Raghav Jaiswal, B N Dental Clinic Darbhanga, Bihar.
When is a Root Canal Treatment Required
Deep Decay
When a cavity goes untreated, it gradually progresses deeper into the tooth, reaching the inner layers where the dental pulp resides. The dental pulp contains nerves, blood vessels, and connective tissue. If the decay reaches this point, it can cause inflammation and infection in the pulp, resulting in severe pain and sensitivity. In such cases, a root canal treatment becomes necessary to remove the infected pulp and save the tooth.

Persistent Toothache
Dr Jaiswal stated that a persistent, throbbing toothache can indicate that the decay has reached the nerve endings within the pulp. The pain may worsen when biting down or applying pressure to the affected tooth. This continuous discomfort is often a clear sign that a root canal procedure is required to eliminate the infection and alleviate the pain.
Sensitivity to Temperature
Experiencing heightened sensitivity to hot or cold temperatures, even after the stimulus is removed, can indicate an underlying issue.
When the decay progresses to the pulp, the nerves become more exposed, causing increased sensitivity. If sensitivity lingers long after exposure to hot or cold substances, it may be an indication that a root canal is needed.
Gum Inflammation and Abscess
According to Dr Jaiswal, advanced decay and infection within the tooth can lead to inflammation of the gums surrounding the affected area. Swelling, tenderness, and the development of a small, pus-filled bump or abscess may occur.
This abscess is a collection of bacteria and dead tissue and often requires immediate attention. A root canal treatment can remove the infection, drain the abscess, and restore oral health.
Darkened or Discoloured Tooth
When the dental pulp is affected, the tooth may darken or develop a grayish hue compared to neighboring teeth. This discoloration is a result of internal changes within the tooth and is a clear indication that a root canal may be necessary to address the underlying issue.

Cavities, if left untreated, can progress to a point where more invasive dental treatment is required. Root canal treatment becomes necessary when the decay reaches the inner layers of the tooth, causing inflammation, infection, severe pain, and sensitivity. It is crucial to pay attention to persistent toothaches, gum inflammation, temperature sensitivity, and tooth discoloration, as these can be signs that a root canal procedure is needed.
Remember, maintaining good oral hygiene, regular dental check-ups, and a balanced diet can help prevent cavities and minimize the need for invasive dental treatments like root canals. When in doubt, consult your dentist, who can provide an accurate diagnosis and recommend the most appropriate course of action to restore your dental health and preserve your smile.
