You don’t just have to put up with sensitivity to hot and cold liquids. You can add the best mouthwash for sensitive teeth and gums to your oral health routine to build back up resiliency.

The problem is, most mouthwashes cause more harm than good with their notorious high-alcohol sting. They dry out already irritated soft tissue and make matters worse. We handpicked the best mouthwash for tooth sensitivity for you below.

Key Takeaways

Alcohol-based mouthwashes worsen sensitivity by drying out gum tissue.
Alcohol-free formulas aren’t effective enough, though. Low alcohol is the way to go.
The best sensitivity mouthwash doesn’t just mask symptoms. It addresses the root cause.
LIVFRESH makes a patented, clinically-backed plaque removal mouthwash that fights sensitivity at the source.

What Causes Tooth and Gum Sensitivity?

That stinging discomfort you feel when drinking very hot or cold liquids is the result of worn-down enamel. The dentin layer under your enamel has lost its protective coating. According to the ADA, “these tubules allow heat and cold or acidic or sticky foods to reach the nerves and cells inside the tooth.”¹

Gum recession makes matters worse. The tissue pulls back and exposes delicate root surfaces that have no natural defense to begin with. The worst part is gum recession is not reversible. That’s why it’s so important to protect gum health proactively.

The sensitivity could be triggered by cavities or a cracked tooth, too. Whatever is giving you grief, the right mouthwash can make a world of difference. So, what separates the best mouthwash for sensitive teeth and gums from the rest?

What Ingredients Are in the Best Mouthwash For Tooth Sensitivity?

First, let’s talk alcohol. A lot of people avoid mouthwash because it’s notoriously difficult to commit to every single day. Let alone twice a day. Brands like Listerine load up the alcohol content to kill bacteria, but this burns - and it can dry out your mouth as a result.

The thing is, alcohol is a somewhat necessary evil. You do need its properties. You just don’t need the concentration it’s so often found in. The answer is a LOW-ALCOHOL formula.

Here are the other ingredients you should look for on the label:

Fluoride (sodium or stannous fluoride): Proven enamel-strengthening properties. It rebuilds the surfaces of your teeth that have worn thin, addressing the source of the sensitivity.
Potassium nitrate: This ingredient actually turns down the intensity of pain. It masks the discomfort while enamel recovers, desensitizing the nerve within the tooth.²
Cetylpyridinium chloride (CPC): An alcohol alternative in mouthwashes. This antiseptic cuts into bacterial load without that harsh burn you’ve come to associate with Listerine.
Stabilized chlorine dioxide: Fights the bacteria that let plaque thrive. Also balances oral pH. Not the most relevant for “the best sensitive tooth mouthwash,” but you’ll see it on labels nonetheless.
Activated Edathamil: An ingredient backed by 40 patents and 40 clinical studies. It dissolves plaque on a molecular level and prevents it from reattaching. May have remineralization properties, too.

What is the Best Mouthwash For Sensitive Teeth and Gums?

The best mouthwash for sensitive teeth and gums should help ease the discomfort, but more importantly, it should put you on the path to recovery by addressing the root cause of your sensitivity. That’s often plaque, which is why LIVFRESH is the #1 choice.

LIVFRESH Mouthwash

LIVFRESH has just 0.1% alcohol, so you won’t deal with that uncomfortable burn that’s even harder to tolerate with tooth and gum sensitivity. The real reason it’s the #1 choice, though, is the Activated Edathamil ingredient, which can help deliver:

72% better plaque reduction
114% better gum health
163% better tartar control

It’s safe for your microbiome and recommended by many dentists. Backed by a 30-day money-back guarantee.

Listerine Total Care Zero

Listerine heard the complaints about its aggressive formulas and came up with a solution - Listerine Total Care Zero. This alcohol-free version still features the essential oil blend Listerine is known for along with fluoride to support enamel repair.

CloSYS Gentle Oral Rinse

This rinse is formulated with Cloralstan, a stabilized chlorine dioxide that stops bacteria without alcohol. It’s pH-balanced as well so you don’t have to worry about the acidity you may have experienced with other mouthwashes, which matters when you already have sensitive teeth.

Tom’s of Maine Natural Antiplaque & Whitening Mouthwash

Tom’s of Maine makes one of the simplest formulas ever to be called the best mouthwash for tooth sensitivity. It’s alcohol-free and fluoride-free. So, what’s actually doing the heavy lifting? Zinc citrate fends off odor-causing bacteria while xylitol and aloe vera soothe sensitive tissue.

Crest Pro-Health Clinical Rinse

Crest’s CPC (0.07%) rinse doesn’t rely on alcohol, instead using this alternative antiseptic for plaque reduction and gingivitis prevention benefits. It’s less likely to dry out your oral tissue and make matters worse than a formula loaded with alcohol.

More Tips on Managing Sensitivity

The best sensitivity mouthwash is a great addition to your oral care routine. But it’s just one piece of the puzzle. There’s more you can do to put discomfort in the past.

First and foremost, make sure you’re not causing unnecessary harm with aggressive brushing. Anyone with sensitivity should use a soft-bristled toothbrush. You should pair your rinse with a good toothpaste for sensitive teeth, too. LIVFRESH has two great options. We recommend the Gum Protect+ formula because it has fluoride, which your teeth desperately need right now.

Keep in mind that even the best mouthwash for sensitive teeth and gums is NOT a replacement for brushing and flossing.³ Whether you use mouthwash before or after brushing, you have to make sure there are no gaps in your oral care habits.

When to Talk to Your Dentist

Most cases of sensitivity can be resolved through at-home remedies, and picking up a bottle of the best mouthwash for tooth sensitivity at LIVFRESH is an excellent start. Give it at least 4 weeks alongside the tips we mentioned above.

If you still deal with daily discomfort after that point, it may be time to schedule an appointment with your dentist. They can better diagnose the issue and determine the best path forward. For example, a cracked tooth is never going to get better without professional intervention. Gum recession is another example of when you want your dentist involved.

In the meantime, take the next step towards relief with LIVFRESH - the best mouthwash for tartar and plaque backed by clinical studies, dental professionals, and real users alike!

Frequently asked questions

Can mouthwash help with tooth sensitivity?

Yes. But the mouthwash in question matters. Some formulas can pull double-duty, strengthening the enamel that’s sensitive while calming the nerves that are flaring up.

Which mouthwash is better, Sensodyne or Listerine?

Sensodyne makes a solid rinse specifically for sensitivity, and Listerine Total Care Zero is a good choice as well. But you may find that neither is actually the best mouthwash for sensitive teeth and gums, because neither dissolves plaque on a molecular level and prevents it from reattaching. That’s what separates LIVFRESH from the rest.
