Canker Sores vs. Cold Sores: Understanding the Discomfort in Your Mouth

Canker Sores vs. Cold Sores: Understanding the Discomfort in Your Mouth

by | Mar 2, 2024 | Dentistry, Laser Dentistry, Prevention

A painful bump or ulcer in your mouth can be frustrating and concerning. While canker sores and cold sores are common culprits, it’s important to remember that mouth sores can have various causes. This post will shed light on the key differences between canker sores and cold sores, helping you navigate the discomfort and seek appropriate solutions.

The Difference Between Canker Sores and Cold Sores: It’s Not All Blisters and Bites

While both canker sores and cold sores bring discomfort, they have distinct characteristics:

Feature Canker Sore (Aphthous Ulcer) Cold Sore (Fever Blister)
Location Inside the mouth: cheeks, tongue, gums Outside the mouth: lips, around the mouth
Appearance Round, white or gray ulcer with a red border Cluster of small, fluid-filled blisters
Size Smaller (usually under 1 cm) Larger (can grow up to 1 cm)
Pain More painful, especially when touched Tingling, burning, itching before blistering
Contagious No Yes, highly contagious through contact
Cause Unknown, linked to stress, diet, injury Herpes simplex virus (HSV-1)

Remember: This is a general comparison. If you experience a mouth sore with unusual characteristics or prolonged healing time, consult your dentist for a diagnosis. Early diagnosis can ensure proper treatment and rule out any other potential causes.

Finding Relief: Exploring Remedies for Mouth Sore Discomfort

While the cause of canker sores remains elusive, several remedies can help manage discomfort and promote healing:

  • Over-the-counter pain relievers: Options like ibuprofen or acetaminophen can help manage pain and inflammation.
  • Topical ointments: Look for gels or ointments containing lidocaine for numbing or zine oxide to protect the sore.
  • Mouth rinses: Use a gentle, alcohol-free mouthwash to maintain oral hygiene without irritation.
  • Dietary adjustments: Avoid acidic or spicy foods that can worsen discomfort. Focus on soft, bland foods.
  • Lysine: This amino acid is a popular over-the-counter option for cold sores. While research results are mixed, some studies suggest it may reduce outbreak frequency or shorten healing time.

Natural Remedies: While research is ongoing, some natural options may offer relief, but be sure to consult your dentist before using any new product:

  • Honey: A natural antibacterial and anti-inflammatory agent, honey can promote healing. Apply a small amount directly to the sore (not recommended for young children).
  • Licorice root: This herb possesses anti-inflammatory properties. Look for licorice root extracts in lozenges or gels (consult your dentist before using licorice root if you have high blood pressure).
  • Aloe vera: The gel from this plant has soothing and healing properties. Apply a small amount to the sore.

Important Note: The effectiveness can vary with these natural remedies. Consult your dentist before using any new product, especially if you have underlying health conditions.

A Promising Option: Laser Therapy

Another area that has shown promise is with the use of a diode laser to treat the affected region of the mouth.

  • Cold Sores: Diode laser therapy, particularly during the prodromal stage (tingling, itching before blisters appear), can potentially prevent a cold sore from fully erupting. Additionally, some patients report a reduced frequency of outbreaks with repeated laser treatments.
  • Canker Sores: Many patients have reported almost immediate relief from painful canker sores after in-office treatment with a diode laser.

Laser therapy offers several potential benefits:

  • Reduced healing time: Laser light may accelerate tissue regeneration, promoting faster healing.
  • Pain relief: Laser therapy can alleviate discomfort associated with both canker sores and cold sores.
  • Reduced risk of infection: Lasers may have a disinfecting effect, minimizing the risk of secondary infections.

Disclaimer: It’s important to note that laser therapy is not a one-size-fits-all solution, and further research is needed to solidify its effectiveness for canker sores

When in Doubt, Consult Your Dentist

While this post provides a general overview, a definitive diagnosis is crucial for proper treatment. Your dentist can examine the sore, determine its cause (canker sore, cold sore, or something else), and recommend the most effective course of action.

By understanding the differences between canker sores and cold sores, exploring potential remedies, and prioritizing a dentist’s diagnosis, you can navigate mouth sore discomfort with more clarity and confidence. Remember, early diagnosis and proper care are key to a speedy recovery and a more comfortable smile.

"La-ser"

Lasers are familiar to many of us from science fiction (think of the Star Wars light saber) to comedy (remember Austin Powers’ Dr. Evil?).  The fact is that lasers surround us in every-day life.  For example, in the home you will find them in CD players, while industry uses them for high-speed metal cutting machines and measuring devices.  Hair replacement, tattoo removal, dermatologists, eye surgeons — they all use lasers.

So do dentists.  And so does our office.

This begs the question, just what is a laser?  How is it different from any other kind of light?  “If Dr. Evil planned to destroy the world with one, why won’t it hurt me when you use it on my gums?!”  Actually, that’s three questions . . . .

Anyway, let’s try take them in order:

The word “LASER” itself is an acronym that stands for light amplification by stimulated emission of radiation.  This concisely describes exactly how a laser works.   The laser is a device which controls the way that energized atoms release photons (a quantum of electromagnetic energy).  When we say “radiation” however, we are not talking about ionizing radiation — such as would be produced by an x-ray.

Laser light is very different from normal light or radiation emitted by an x-ray.  Laser light has the following properties:

  • The light released is monochromatic. It contains one specific wavelength of light (one specific color). The wavelength of light is determined by the amount of energy released when the electron drops to a lower orbit.
  • The light released is coherent. It is “organized” — each photon moves in step with the others. This means that all of the photons have wave fronts that launch in unison.
  • The light is very directional. A laser light has a collimated (very tight) beam.  This makes it stronger and concentrated. A flashlight, on the other hand, releases light in many directions, and the light is very weak and diffuse.

Why won’t it burn you to a crisp when we use it on your gums?  Clearly, we’re using a controlled power setting (in our office we use a diode laser) — in fact, most patients tell us they don’t feel anything when we use it in conjunction with their dental cleanings.  But that doesn’t mean it isn’t effective!

Watch the video below for a demonstration and explanation of how a dental laser is being used during a routine cleaning.
