Dentist Tested and Reviewed

Oral pain can be a real show-stopper when you least expect it.

Pain response can be triggered from many sources, including teeth, jaw, soft tissue, or gums.

While most oral pain needs to be assessed and treated by your clinician, you can get some pain relief with over-the-counter rinses.

In addition, oral pain has an increased effect on our mood, thoughts, and actions.

As an experienced dentist with years of experience, I’ve tested and evaluated 250+ dental products. I strive to find the best products for achieving excellent oral hygiene, so let’s take a closer look at the Best Pain Relief Mouthwash from a dentist’s perspective.

Buying Guide

1. Best Overall: Colgate Peroxyl Mouth Sore Rinse
2. Best Sensitivity: Oral-B Mouth Sore Oral Rinse
3. Best Antiseptic: Orajel Mouth Sores Antiseptic Rinse
4. Best Travel-Ready: Gly-Oxide Antiseptic Oral Cleanser

Oral Pain Causes

• Mouth burns
• Accidental injury
• Minor dental procedures
• Canker sores
• Irritations
• Cheek bites
• Braces and dentures irritation

Evaluation Criteria

I test each product for 7-14 days, detailing its pros and cons, and rate it from 1 to 5 in four key areas.

• Effectiveness: Does the oral rinse treat the advertised need? How effective were the results?
• Comfort: Are you able to swish for recommended time? Did it sting or burn? How did the mouth feel afterwards?
• Taste: How was the overall taste? Was it tolerable? Did it alter your sense of taste?
• Likeability: Is the product likeable and enjoyable to use? Are you able to use it as directed?

Best for patients that desire effective pain relief and fresh breath.

Dentist Review

Peroxyl mild mint offers the best mild mint flavor. It’s comfortable to swish and provides a slight numbing effect on the oral tissue.

It provides effective pain relief as well.

It has slightly less cooling effect than others and less foam for those who may have trouble tolerating that.

Cons

Upon rinsing, a slightly bitter aftertaste seemed to subside soon after.

Best for patients with sensitive gums and who desire cooling pain relief.

Dentist Review

Oral-B’s Special Care Rinse Collection has done an excellent job of eliminating undesirable ingredients, including parabens, artificial dyes, sodium lauryl sulfate (SLS) and gluten.

The soothing mint flavor has just the right amount to freshen your breath without being overpowering.

It was effective at relieving oral pain and was comfortable to swish and rinse.

The hydrogen peroxide provided a pleasant foaming sensation that transitioned to a lasting cooling effect. It’s a likable mouth sore relief rinse.
