Tooth infections or decay can affect more than just your comfort—they can threaten the health of your entire smile. A root canal is a procedure that saves a natural tooth when the inner tissue, known as the pulp, becomes inflamed or infected. Without treatment, infection can spread to the gums, bone, or surrounding areas, leading to abscesses and tooth loss. Visit Listiyo Family Dental in Long Beach, CA, to preserve your tooth and restore lasting oral health.
Understanding Root Canal Therapy
A root canal removes the infected or inflamed pulp inside the tooth and seals it to prevent reinfection. The pulp contains nerves and blood vessels that help nourish the tooth, but when it becomes infected, removing it is necessary to save the tooth structure. The treatment relieves discomfort and helps maintain proper chewing and bite alignment.
- Tooth preservation: Protects and retains the natural tooth instead of extracting it
- Infection control: Removes bacteria before it can spread to nearby tissue
- Comfort restoration: Eliminates infection-related discomfort and sensitivity
- Durable results: The treated tooth can last for many years with good care
Causes & Risk Factors
Root canal treatment becomes necessary when bacteria reach the inner pulp, often due to untreated decay or injury. Repeated dental procedures, deep cavities, or cracks can expose the pulp to infection. Even a tooth without visible damage can experience pulp inflammation after trauma.
- Deep decay: Cavities that extend into the pulp chamber cause infection
- Tooth injury: Chips or fractures can expose the inner tissue to bacteria
- Worn restorations: Damaged fillings or crowns allow bacteria to enter
- Repeated procedures: Over time, restorative work can irritate the pulp
Recognizing Symptoms
Recognizing the signs of a tooth infection early can make a difference in saving the tooth. Common symptoms include persistent toothache, sensitivity to hot or cold, and swelling of the gums. The affected tooth may also appear darker in color or feel tender to touch or pressure.
- Lingering discomfort: Continuous or throbbing pain when chewing or resting
- Temperature sensitivity: Sharp or dull sensation that persists after exposure
- Gum swelling: Puffiness or tenderness around the affected tooth
- Tooth discoloration: A gray or dark shade may indicate nerve damage
Diagnosis & Dental Connection
Dentists play a key role in diagnosing pulp infections and recommending the right treatment. Using digital x-rays and diagnostic tools, they can assess the tooth’s internal health and identify infection before it spreads. In certain cases, patients may be referred for specialized endodontic care.
- Diagnostic imaging: X-rays reveal infection, decay, or abscess formation
- Pulp testing: Determines if the tooth’s nerve is still viable
- Bite evaluation: Identifies sensitivity or inflammation triggered by pressure
- Professional assessment: Dentists plan treatment to preserve natural teeth
Treatment Options & Management
Root canal therapy focuses on cleaning, disinfecting, and sealing the tooth to restore normal function. Once the pulp is removed, the inner space is filled with a biocompatible material and sealed to prevent bacteria from returning. A crown is often placed afterward to strengthen the tooth and protect it from further damage.
- Root canal procedure: Removes infected tissue and seals the inner chamber
- Dental crown restoration: Reinforces strength and function post-treatment
- Antibiotic use: May be recommended to address residual infection
- Preventive visits: Routine checkups help monitor and maintain oral health
