Swollen gums and tenderness around a specific tooth can be easy to dismiss, especially when discomfort comes and goes. However, persistent swelling may indicate an infection inside or around the tooth that requires professional attention. When bacteria reach the dental pulp, a root canal may be necessary to remove infected tissue and preserve the natural tooth.
 

At Le Smile Aesthetic & Comprehensive Dentistry, we provide root canal treatment and advanced laser dentistry for patients in Falls Church. Our Fotona LightWalker laser technology can support more thorough cleaning of the root canal system while helping us provide a precise, patient-focused experience.
 

Why an Infected Tooth Can Cause Swollen Gums

Inside every tooth is dental pulp containing nerves, blood vessels, and connective tissue. Deep decay, cracks, chips, or trauma can allow bacteria to reach this sensitive area. Once the pulp becomes severely inflamed or infected, the problem cannot always heal on its own.
 

An infection may eventually spread beyond the root tip and form an abscess. This can produce localized gum swelling, tenderness, and pain around the affected tooth. Root canal treatment removes the damaged pulp, cleans the canals, and seals the tooth so it can remain functional rather than being extracted.
 

Signs You May Need a Root Canal

Tooth infections do not feel the same for every Falls Church patient. Some create significant pain, while others produce only mild tenderness or a small bump on the gum.
 

Schedule a dental evaluation if you notice:
 

• Persistent or severe tooth pain
• Swollen or tender gums around one tooth
• Sensitivity to hot or cold that lingers
• Pain when biting or chewing
• A pimple-like bump on the gum
• Darkening or discoloration of a tooth
• Facial or jaw swelling
• A cracked or deeply decayed tooth

Pain can sometimes decrease when the nerve inside a severely damaged tooth dies, but the infection may remain. Feeling better does not always mean the problem has resolved.
 

What Happens During Root Canal Treatment?

The first step is determining whether the pulp is actually infected. We examine the tooth, discuss your symptoms, and may take dental X-rays to evaluate the roots and surrounding bone.
 

During root canal treatment, the tooth is numbed and isolated. The infected or inflamed pulp is removed, and the small canals inside the roots are thoroughly cleaned and disinfected before being filled and sealed. Depending on how much tooth structure remains, a dental crown may be recommended afterward to restore strength and function.
 

Modern anesthesia and dental technology make root canal therapy much more comfortable than its outdated reputation suggests.
 

How Fotona LightWalker Supports Root Canal Care

Le Smile uses Fotona LightWalker laser technology as part of its advanced dental services in Falls Church. For endodontic procedures, the system incorporates PIPS and SWEEPS technology. These techniques use laser-generated photoacoustic energy to activate cleaning solutions inside the root canal system.
 

This movement helps cleaning and disinfecting solutions reach complex spaces within the tooth that can be difficult to access mechanically. The laser also allows the dentist to work with precision while complementing the other important steps involved in root canal therapy.
 

Laser dentistry can be especially appealing to patients who feel nervous about dental treatment. Le Smile incorporates advanced technology with a focus on patient comfort and comprehensive care.
 

Do Not Wait for Swelling to Become Severe

A tooth infection can spread beyond the tooth if left untreated. Increasing facial swelling, fever, difficulty swallowing, or difficulty breathing requires urgent medical or dental attention.
 

For less severe symptoms, scheduling an evaluation when tenderness, sensitivity, or gum swelling first appears can give your dentist more options for protecting the tooth. The goal of root canal treatment is to remove infection, relieve the source of discomfort, and preserve as much of your natural smile as possible.
