Cold sores are a common, frustrating, and often painful issue that can affect your quality of life. At Sovrle Dental Clinic in North York, ON, we understand the discomfort they cause. Our use of advanced dental lasers provides a modern, effective solution to treat these painful lesions, offering immediate relief and promoting fast healing.
This guide will help you understand what cold sores are and how our laser treatment can improve your oral health and comfort.
What Is a Cold Sore?
A cold sore, also known as a fever blister, is a small, fluid-filled blister that appears on or around the lips. They are caused by the herpes simplex virus (HSV-1). It's important to distinguish them from other conditions:
Cold Sore vs. Impetigo
Unlike impetigo, which is a bacterial skin infection with crusty, honey-coloured sores, a cold sore is a viral blister that typically appears on the lip line.
Sunburned Lips vs. Cold Sores
While a cold sore can be triggered by sun exposure, sunburned lips are dry and chapped without the characteristic blister of a cold sore.
Cold Sore vs. Angular Cheilitis
While some viral infections can manifest at the corners of the mouth, angular cheilitis is a separate condition usually caused by a fungal or bacterial infection.
Cold sore vs. Canker Sores
Cold sores appear outside the mouth, on the lips, and are caused by a virus. Canker sores occur inside the mouth and are not contagious.
What Are the Common Cold Sore Symptoms?
The journey of a cold sore follows several predictable stages. Knowing these stages can help you seek treatment at the first sign.
Stage 1 (Tingling):
An itching, burning, or tingling sensation is often felt around the lips.
Stage 2 (Blistering):
Within a day or two, fluid-filled blisters appear, often along the border of the lips.
Stage 3 (Weeping):
The blisters burst and a shallow, open sore is formed. This is the most painful and contagious stage.
Stage 4 (Crusting):
The sores dry out and crust over, a signal that healing is beginning.
Stage 5 (Healing):
The scabs fall off, and the new skin is revealed.
Possible Causes and Triggers
What causes cold sores?
Cold sores are caused by the herpes simplex virus (HSV-1), which is highly contagious and can be transmitted through close personal contact like kissing or sharing food utensils. Another very common transmission is during sports events in sharing water bottles (or even mouthguards!). Once you have the virus, it remains dormant in your nerve cells, and can be reactivated by various triggers.
What Foods Can Trigger Cold Sores?
Foods that trigger cold sores can include those high in the amino acid arginine, such as chocolate, nuts, and some grains. Contrary to popular belief, spicy foods don’t trigger cold sores.
What Foods Should You Stay Away From With Cold Sores?
Foods to stay away from with active cold sores are generally:
spicy,
acidic,
or salty
While these foods don't generally trigger cold sores, they do irritate active sores!
Environmental Cold Sore Triggers
cold, dry weather
sun and UV exposure
illness
stress
hormonal fluctuations (estrogen and progesterone primarily)
Care and Treatment
What should I know about cold sore treatment?
While there are many over-the-counter options, our professional, in-clinic cold sore laser treatment offers a superior alternative for faster, more effective relief.
The Sovrle Dental Difference: Laser Treatment Therapy
Our specialized treatment uses a soft tissue laser to treat the lesion directly. This procedure is a modern, minimally invasive alternative to traditional methods, offering a more comfortable experience with the following benefits:
Immediate Relief: Patients often report a significant reduction in pain and discomfort immediately after treatment, often eliminating the need for anesthesia.
Faster Healing: The laser accelerates the healing process, allowing the sore to disappear in just a few days instead of a week or more.
Prevents Recurrence: Laser treatment can significantly reduce the frequency of future outbreaks in the treated area.
Exceptional Precision: The laser targets the specific lesion with pinpoint accuracy, protecting the surrounding healthy tissue.
Removing a Cold Sore Scars
The lingering mark of a cold sore can be a frustrating reminder of a past outbreak. While traditional cold sores can leave behind a scar due to deep tissue damage and the crusting-over process, our laser treatment therapy offers a way to prevent this from happening.
By promoting rapid and clean healing, the laser minimizes the tissue damage that leads to scar formation. The procedure accelerates your natural recovery process, ensuring the cold sore heals smoothly and efficiently.
Instead of trying to treat a scar after it has formed, laser treatment helps you avoid the problem altogether.
Frequently Asked Questions
How long does a cold sore last?
Without treatment, cold sores typically last for 7 to 10 days.

Primary (first-time) infections of HSV-1 can sometimes cause sores on the gums or roof of the mouth, but recurrent cold sores almost always appear on the lips.
